2. Description of the Related Art Conventionally, bedding such as a mattress formed by covering a cushion material containing charcoal such as activated carbon, Bincho charcoal, bamboo charcoal, and pine nut charcoal with a cover material is known. Such a charcoal-containing cushioning material is produced, for example, by applying charcoal particles mixed with an aqueous binder to the surface of a cut flexible polyurethane foam, impregnating the inside slightly, and then evaporating water.
JP 2001-164032 A

しかし、上記の方法によれば、炭粒子はポリウレタンフォームの表面部に付着するが、同時に水性結合剤中に含まれる固形成分も付着してしまうために、ポリウレタンフォームの表面部が硬くなるとともに小さな力では伸びづらくなる。そのため、本来軟質ポリウレタンフォームが有する身体の形状への追従性、いわゆる体圧分散性が低下して図11に示すように身体の最も低い部分に体圧が集中するという問題がある。
本発明は、結合剤により付着した炭粒子を有しながらも、良好な体圧分散性を発現する炭入りクッション材を提供するものである。
However, according to the above method, the carbon particles adhere to the surface portion of the polyurethane foam, but at the same time, the solid component contained in the aqueous binder also adheres, so that the surface portion of the polyurethane foam becomes hard and small. It becomes difficult to grow with force. Therefore, there is a problem that the followability to the body shape inherent in the flexible polyurethane foam, so-called body pressure dispersibility, is lowered and the body pressure concentrates on the lowest part of the body as shown in FIG.
The present invention provides a charcoal-containing cushioning material that exhibits good body pressure dispersibility while having charcoal particles adhered by a binder.

本発明の炭入りクッション材は、炭粒子が表面に付着したポリウレタンフォームを含むクッション材において、炭粒子の付着部位は、凹部凸部の繰り返し面全域に連続しないように、凹部のみ又は凸部のみとされている
また、凹部と凸部の高低差が、最短距離に隣接する凸部頂点間の距離よりも大きくしてあることが好ましい。
さらに、凹部凸部の繰り返し面が、プロファイル加工により平面視千鳥格子状にされたものであることが好ましい。
The cushion material containing charcoal of the present invention is a cushion material including a polyurethane foam having charcoal particles attached to the surface, and the adhering site of the charcoal particles is only a concave portion or only a convex portion so as not to be continuous over the entire repeated surface of the concave convex portion. It is said that .
Moreover, it is preferable that the height difference between the concave portion and the convex portion is larger than the distance between the convex vertexes adjacent to the shortest distance.
Furthermore, it is preferable that the repetitive surface of the concave convex portion is formed in a staggered pattern in plan view by profile processing.

本発明のクッション材は、炭粒子の付着部位が、凹部凸部の繰返し面全域に連続しないように、凸部のみあるいは凹部のみとされ、フォームの表面部を伸ばそうとする力は、炭粒子の付着してない部分が伸びることで吸収されるので、身体形状への追従性の低下の問題は大きく改善される。そして、炭粒子の付着した部分が凸部を除いた部分とされた場合には、凸部への体圧の集中を緩和させることができる。
The cushion material of the present invention has only the convex part or the concave part so that the carbon particle adhesion site does not continue over the entire repeated surface of the concave convex part, and the force to stretch the surface part of the foam is Since the unattached portion is absorbed by stretching, the problem of a decrease in follow-up to the body shape is greatly improved. And when the part to which the carbon particle adhered was made into the part except a convex part, the concentration of the body pressure to a convex part can be eased.

炭粒子の付着した部分が凸部のみとされた場合には、凹部と凸部の高低差が最短距離に隣接する凸部間の距離よりも大きくすることで、身体荷重がかかったときに、凸部は比較的沈み込みやすくなるし、また横向き倒れやすくなるので、凸部への体圧の集中を緩和させることができる。   When the part to which the carbon particles are attached is only a convex part, when the body load is applied by making the height difference between the concave part and the convex part larger than the distance between the convex parts adjacent to the shortest distance, Since the convex portion is relatively easy to sink and is liable to fall sideways, the concentration of body pressure on the convex portion can be alleviated.

凹部凸部の繰り返し面が、プロファイル加工により平面視千鳥格子状とされた場合には、それぞれの凸部は、海に浮かぶ島のように孤立していることになるので、身体による荷重がかかったときに、その身体の形状に追従してフォームの表面部を表面方向に伸ばそうとする力自体がほとんど発生しない。したがって、フォームの表面部の伸び性の低下により身体の形状への追従性が低下するといった問題が大きく改善されるという効果がある。   If the repeated surface of the concave convex part is made into a staggered pattern in plan view by profile processing, each convex part is isolated like an island floating in the sea, so the load by the body is When applied, almost no force is generated to follow the shape of the body and to extend the surface of the foam in the surface direction. Therefore, there is an effect that the problem that the followability to the shape of the body is lowered due to the decrease in the extensibility of the surface portion of the foam is greatly improved.

本発明の炭入りクッション材の実施形態を以下図面に基づいて具体的に説明する。本発明の炭入りクッション材は、図1、図2に示すように、表面が凹部凸部の繰り返し面とされている軟質ポリウレタンフォームを用いる。図1のフォーム2は、表面が平面視千鳥格子状の凹部凸部の繰り返し面とされたもので、図2のフォーム3は、表面が縞状の凹部凸部の繰り返し面とされたものである。   Embodiments of the charcoal cushion material of the present invention will be specifically described below with reference to the drawings. As shown in FIGS. 1 and 2, the charcoal-filled cushion material of the present invention uses a flexible polyurethane foam whose surface is a repetitive surface of concave convex portions. Form 2 in FIG. 1 is a surface whose surface is a repeating surface of concave projections in a staggered pattern in plan view, and Form 3 in FIG. 2 is a surface whose surface is a repetition surface of striped concave projections. It is.

図1、図2に示すようなフォームは、図3に示すようなプロファイル加工装置5を使用して作製することができる。プロファイル加工とは、機械的にフォームを変形させて、変形状態のフォームを裁断することで凹部凸部の繰り返し面を形成する加工のことを言う。図2に示すようなフォームは2次元裁断機でも作製することができる。   The foam as shown in FIGS. 1 and 2 can be produced using a profile processing apparatus 5 as shown in FIG. Profile processing refers to processing in which the foam is mechanically deformed, and the deformed foam is cut to form a repeated surface of the concave convex portion. The foam as shown in FIG. 2 can also be produced with a two-dimensional cutter.

炭粒子は、結合剤に分散されたのち塗布によりフォームの表面部に付着される。結合剤としては、水分と反応して固化するウレタンプレポリマー、水分の蒸発により固化する水性接着剤などが挙げられるが、固形成分の使用量の割に多くの炭粒子をフォームに付着できる点で水性接着剤が好ましい。水性接着剤は、乾燥性、含浸性などを考慮して固形成分30〜60重量%のものを炭粒子1重量部に対し3〜30重量部の割合で用いることが好ましい。フォームへの前記固形成分の付着量は、炭粒子の付着部において表面積1mあたり60〜600gとすることが好ましい。固形成分があまり少ないと炭粒子をフォームへ付着させ難く、多いと炭粒子の付着部が硬くなりクッション材の体圧分散性が悪化する傾向にある。また、炭粒子の付着部において、表面を基準として1〜2mm深さにおける空間の割合が70%以上であることが好ましい。この部位におけるフォームの気泡が前記固形成分で埋まって空間が70%未満になるようであるとクッション材の体圧分散性が悪化する傾向にある。 The charcoal particles are dispersed in the binder and then attached to the surface portion of the foam by coating. Examples of the binder include urethane prepolymer that solidifies by reacting with moisture, and water-based adhesive that solidifies by evaporation of moisture. However, in terms of being able to adhere many carbon particles to the foam for the amount of solid components used. A water-based adhesive is preferred. The water-based adhesive is preferably used in a proportion of 3 to 30 parts by weight with respect to 1 part by weight of the carbon particles in consideration of drying properties, impregnation properties and the like. The amount of the solid component attached to the foam is preferably 60 to 600 g per 1 m 2 of the surface area in the part where the carbon particles are attached. If the solid component is too small, the charcoal particles are difficult to adhere to the foam. If the solid component is large, the adhering portion of the charcoal particles becomes hard and the body pressure dispersibility of the cushion material tends to deteriorate. Moreover, in the adhesion part of carbon particle, it is preferable that the ratio of the space in 1-2 mm depth is 70% or more on the basis of the surface. When the foam bubbles in this region are filled with the solid component and the space is less than 70%, the body pressure dispersibility of the cushion material tends to deteriorate.

炭粒子の塗布手段としては、吹付け、ロールコーティングなどが利用できる。このような炭粒子の付着方法によれば、フォームの表面及びある程度の深さまでの表面部に炭粒子を付着させることができる。炭粒子を付着させる深さは、1〜5mmとすることが好ましい。炭粒子の付着深さをあまり深くすると、炭付着によって硬化したフォームの表面部が、身体荷重によって変形したのち復元しない傾向にあるばかりでなく、クッション材の体圧分散性も悪化する傾向にある。炭粒子の付着量は、炭粒子の付着部において表面積1mあたり10〜100gとすれば消臭効果が得られる。 Spraying, roll coating, or the like can be used as a means for applying the carbon particles. According to such an adhesion method of charcoal particles, charcoal particles can be adhered to the surface of the foam and a surface portion up to a certain depth. The depth to which the carbon particles are attached is preferably 1 to 5 mm. If the adhesion depth of the charcoal particles is too deep, the surface portion of the foam cured by the charcoal adhesion tends not to be restored after being deformed by body load, and the body pressure dispersibility of the cushioning material also tends to deteriorate. . The deodorizing effect can be obtained if the amount of carbon particles attached is 10 to 100 g per 1 m 2 of the surface area in the carbon particle adhesion part.

炭粒子は、活性炭、備長炭、竹炭、松果炭などが利用される。炭粒子の大きさは特に限定されないが、フォームのやや内側にも付着させるためにフォームの平均セル径よりも小さくする必要があり、100μm以下とすることが好ましい。   For the charcoal particles, activated carbon, Bincho charcoal, bamboo charcoal, pine nut charcoal and the like are used. The size of the charcoal particles is not particularly limited, but it needs to be smaller than the average cell diameter of the foam in order to adhere to the inner side of the foam, and is preferably 100 μm or less.

軟質ポリウレタンフォームは、一般にはポリオキシアルキレンポリオールなどのポリオールおよびジイソシアネートに、発泡剤、製法剤および触媒等の副原料を混合することによって製造される。   A flexible polyurethane foam is generally produced by mixing auxiliary materials such as a foaming agent, a preparation agent and a catalyst with a polyol such as a polyoxyalkylene polyol and a diisocyanate.

ポリオールとしてポリオキシアルキレンポリオール中でアクリロニトリル、スチレンなどのエチレン性不飽和単量体を重合させて得たポリマーポリオールをポリオキシアルキレンポリオールに含んだものを使用することで、軟質ポリウレタンフォームは高弾性となり本発明の炭入りクッション材としては好ましい。つまり、結合剤中に含まれる固形成分によって硬化したフォームの表面部分は、身体荷重によって変形したまま復元しない傾向にあるのだが、高弾性フォームを使用することで復元性を保つことができる。   By using a polyoxyalkylene polyol that contains a polymer polyol obtained by polymerizing an ethylenically unsaturated monomer such as acrylonitrile or styrene in a polyoxyalkylene polyol, the flexible polyurethane foam becomes highly elastic. The charcoal-containing cushion material of the present invention is preferable. That is, the surface portion of the foam hardened by the solid component contained in the binder tends to not be restored while being deformed by the body load, but the resilience can be maintained by using a highly elastic foam.

クッション材は、単一のポリウレタンフォームでも良いし、凹部凸部の繰り返し面の反対側に別のポリウレタンフォーム、ポリエチレンフォームあるいは固綿などを積層した積層構造としても良い。   The cushion material may be a single polyurethane foam, or may be a laminated structure in which another polyurethane foam, polyethylene foam, solid cotton or the like is laminated on the opposite side of the concave convex portion.

炭粒子を付着するポリウレタンフォームは、密度30〜40kg/mのものが好ましい。これより密度が小さいと良好な弾性が発現せず、これより密度を大きくしても重くなるばかりである。このような密度範囲のもとでポリウレタンフォームは、硬さ130〜190N(JIS−K6400−2:D法)のものが好ましい。これより硬さが小さいと、炭の付着によって硬化したフォームの表面部分が、身体荷重によって変形したのち復元しない傾向にあり、これより硬さが大きいと凸部に体圧が集中して体圧分散性が悪化する傾向にある。 The polyurethane foam to which the carbon particles adhere is preferably one having a density of 30 to 40 kg / m 3 . If the density is lower than this, good elasticity will not be exhibited, and even if the density is increased, it will only become heavy. Under such a density range, the polyurethane foam preferably has a hardness of 130 to 190 N (JIS-K6400-2: Method D). If the hardness is lower than this, the surface portion of the foam hardened by the adhesion of charcoal tends to not be restored after being deformed by body load. Dispersibility tends to deteriorate.

図1に示すように、凹部凸部の繰り返し面が、平面視千鳥格子状に形成されたものにあっては、図4、図5及び図6に示すように凹部と凸部の高低差hが最短距離に隣接する凸部間の距離pよりも1〜20%大きいことが好ましい、図2に示すように、凹部凸部の繰り返し面が、縞状に形成されたものにあっては、図7、図8及び図9に示すように凹部と凸部の高低差hが隣接する凸部間の距離pよりも1〜60%大きいことが好ましい。この割合があまり大きいと身体荷重を受けたときにすべての凸部が倒れやすくなるので体圧分散性が悪化する傾向にある。   As shown in FIG. 1, when the concave and convex portions have a repeating surface formed in a staggered pattern in plan view, the height difference between the concave and convex portions as shown in FIGS. It is preferable that h is 1 to 20% larger than the distance p between the convex portions adjacent to the shortest distance. As shown in FIG. 2, the repeating surface of the concave convex portions is formed in a stripe shape. 7, 8, and 9, it is preferable that the height difference h between the concave portion and the convex portion is 1 to 60% larger than the distance p between the adjacent convex portions. If this ratio is too large, all the convex portions are liable to fall when subjected to a body load, so that the body pressure dispersibility tends to deteriorate.

前記高低差h及び前記凸部間の距離pの数値範囲は、図4〜図9で説明すると、hが30〜50mmであり、pが20〜40mmであることが好ましい。高低差hがあまり小さいと体圧分散性が不足する傾向にあり、あまり大きくしても体圧分散性の向上はみられない。凸部間の距離pが20mmより小さいと凸部の容積が小さくなって破損しやすくなり、40mmより大きいと体圧分散性が悪化する傾向にある。   The numerical range of the height difference h and the distance p between the convex portions will be described with reference to FIGS. 4 to 9. It is preferable that h is 30 to 50 mm and p is 20 to 40 mm. If the height difference h is too small, the body pressure dispersibility tends to be insufficient. Even if the height difference h is too large, the body pressure dispersibility is not improved. If the distance p between the convex parts is smaller than 20 mm, the volume of the convex parts becomes small and easily damaged, and if it is larger than 40 mm, the body pressure dispersibility tends to deteriorate.

(炭入り水性結合剤の作製)松果炭粒子と水とを1:3.5の割合で混ぜた後、このものに対して水性1液ゴム系接着剤(SIMALFA−309固形分濃度54重量%;ALFA Klebstoffe AG社製)を1:4の割合で混ぜて炭入り水系結合剤を作製した。この炭入り水性結合剤は、100gあたり炭粒子4.4g、固形成分43.2g、水分52.4gである。松果炭粒子は250メッシュの篩を通過したものを使用した。   (Production of charcoal-containing aqueous binder) After mixing pine nut charcoal particles and water in a ratio of 1: 3.5, an aqueous one-pack rubber adhesive (SIMALFA-309 solid content concentration 54 wt. %: ALFA Klebstoff AG) was mixed at a ratio of 1: 4 to prepare a charcoal-based water-based binder. This charcoal-containing aqueous binder has 4.4 g of charcoal particles, 43.2 g of solid components, and 52.4 g of water per 100 g. The pineapple charcoal particles passed through a 250 mesh sieve were used.
