【発明の詳細な説明】 〔技術分野〕 本発明は、建築用複合断熱板材の改良に関し、建築材
料を製造、販売、使用する産業分野で利用されるもので
ある。Description: TECHNICAL FIELD The present invention relates to improvement of a composite heat insulating plate material for construction, and is used in the industrial field of manufacturing, selling, and using construction materials.
近時、建築物の軽量化、工期の短縮化、省エネルギー
等の目的から、所謂A.L.C.板材（軽量気泡コンクリート
板材）が大量に使用されていることは周知であり、ま
た、A.L.C.板材は極めて軽量であり、優れた断熱性及び
切断、打釘の容易性等々の数多くの長所を備えているた
めに最近益々その需要が増大しつつあることも周知であ
る。Recently, it is well known that so-called ALC board materials (lightweight aerated concrete board materials) are used in large quantities for the purpose of reducing the weight of buildings, shortening the construction period, and saving energy, and ALC board materials are extremely lightweight. It is also well known that the demand thereof has recently been increasing more and more because of its many advantages such as excellent heat insulating property, cutting property, and ease of nailing.
然るに、A.L.C.板材には多数の気泡が内在されている
ため、その強度は必ずしも充分満足するべきものではな
く、且つまた、耐水性及び非透水性に全く欠けるため、
極めて湿潤、透水し易く、したがって乾燥時には抜群の
良断熱性を示すが、湿潤時には断熱性、強度性が大巾に
低下するという重大な欠点がある。However, since a large number of air bubbles are contained in the ALC plate material, its strength is not necessarily satisfactory, and since it is completely lacking in water resistance and water impermeability,
It is extremely wet and easily permeable to water, and therefore exhibits excellent heat insulation properties when dried, but has a serious drawback that the heat insulation properties and strength are greatly reduced when wet.
そこで、A.L.C.板材の強度を向上するために、鉄筋、
金網等の補強材を内装した製品が開発提供されている
が、切断時及び打釘時にそれらの補強材が障害になるば
かりでなく、例えば隅角部等の補強材不在個所の脆弱欠
点は全く改善され得ぬと共に、補強材の内装は資材及び
工程の増加を来すために不経済である。Therefore, in order to improve the strength of the ALC plate,
Products containing reinforcing materials such as wire nets have been developed and provided, but not only do these reinforcing materials hinder cutting and nailing, but there are no fragile defects in the absence of reinforcing materials such as corners. While it cannot be improved, the interior of the reinforcing material is uneconomical due to the increase of materials and processes.
また、耐水性の向上及び湿潤の防止を図って、防水塗
料を塗布したり、防水被膜で被覆したりする手段が用い
られているが、未だに湿潤時における良断熱性を充分満
足できる程度に保ち得るものは提供されていない。In addition, a means for applying a waterproof coating or covering with a waterproof film is used to improve water resistance and prevent wetting, but still keep good thermal insulation to a sufficient degree when wet. No gain is offered.
本発明は、上記背景技術に鑑みて発明されたもので、
すなわち、従来のA.L.C.板材に較べて、曲げ強度、圧縮

な建築用複合断熱板材を提供することを目的とする。The present invention has been invented in view of the above background art,
That is, it is an object of the present invention to provide an extremely useful composite heat insulating plate material for construction, which is excellent in bending strength, compressive strength, water resistance, heat insulating property, workability, etc., as compared with conventional ALC plate materials.

物層を一体的に層成して構成されている。In order to achieve the above-mentioned object, the composite heat insulating board material for construction according to the present invention, an adhesive agent is applied to the surface of the plywood, and then 1.5 to 10 parts by weight of an asphalt aqueous emulsion is added to 100 parts by weight of cement. Add to it the required amount of water,
An uncured lightweight mortar mixture made by adding aggregate and 0.001 to 5 parts by weight of protein-based air entraining agent, etc. is poured and allowed to foam and cure, and the above lightweight mortar mixture layer is integrally laminated on a plywood via an adhesive. Is configured.
本発明において、軽量モルタル混合物の成分範囲を上
記の割合に規定したのは次の理由に基づく。In the present invention, the component range of the lightweight mortar mixture is defined as the above ratio for the following reason.
セメント100重量部に対してアスファルト水性エマル
ジョンの添加量が1.5重量部未満の場合は、製品板材の
気泡体の強度が低く、且つ吸水性が大きくなって性能的

接着剤と軽量モルタル混合物層との結合強度が低下する
ものでもあった。When the addition amount of the asphalt aqueous emulsion is less than 1.5 parts by weight with respect to 100 parts by weight of cement, the strength of the foam of the product plate material is low, and the water absorption becomes large, and a satisfactory value cannot be obtained in terms of performance, Further, it was found that when the amount exceeds 10 parts by weight, further improvement in performance cannot be expected and the cost increases. Moreover, when the amount of the asphalt aqueous emulsion added exceeds 10 parts by weight, the water absorbency of the lightweight mortar mixture becomes too low, which makes it difficult for the adhesive to impregnate it, and the adhesive and lightweight mortar mixture layer There was also a decrease in the bonding strength with.

る。Further, when the amount of protein-based air entraining agent added to 100 parts by weight of cement is less than 0.001 parts by weight, the specific gravity of the product plate material becomes high and the heat insulating property deteriorates, and the desired performance cannot be expected, Further, if it exceeds 5 parts by weight, the specific gravity is lowered and the heat insulating property is improved, but the strength as a plate material is lowered, and it has been found that there is a problem in strength at the current research stage.

0.05 parts by weight, 0.01 parts by weight of alkali-resistant glass fiber, and 60 parts by weight of water are added, and a sufficiently kneaded uncured lightweight mortar mixture is poured and cured to integrally layer the lightweight mortar mixture on plywood. A composite heat insulating plate material was obtained.

In addition to being improved, the appearance is also good, and the work period can be shortened by labor saving of the process.

て、両者が強固に層成一体化されるものである。As described above, the composite heat insulating board material for construction of the present invention has excellent heat insulation and water resistance characteristics as compared with the conventional ALC board material due to the unique mixing components and mixing ratios of the lightweight mortar mixture layered on the plywood. Since it is provided and is excellent in terms of bending strength, compressive strength, workability, etc., it can exert an unparalleled effect as a building board material. In particular, in the composite heat insulating board material for construction of the present invention, an adhesive is applied to the surface of the plywood and a lightweight mortar mixture layer is integrally laminated on the surface of the plywood, so that the thickness is replenished by the base plywood. It is possible to form a thin mortar mixture layer that is rich in fire resistance and waterproofness on the surface side, completes curing of the lightweight mortar mixture layer in a short time, and can be manufactured easily and inexpensively, and, The adhesive applied to the surface of the plywood penetrates into the surface of the plywood and the back surface of the lightweight mortar mixture layer, which is uneven due to the bubbles, in an anchor form, and both are firmly layered and integrated.

断熱性及び耐水性は一層向上されるものである。Furthermore, in the present invention, since a protein-based air entraining agent is used as a means for containing bubbles, the diameter of the bubbles generated can be freely changed by changing the addition amount, stirring time, and stirring speed. In addition to the great advantage that the above various properties can be easily adjusted, all the bubbles generated by the protein-based air communicating agent are independent bubbles, and thus the above heat insulation and water resistance are further improved. .
