Attempts to absorb condensation have been disclosed (see, for example, Patent Document 1).
The dew condensation absorbing sheet is a sheet in which an adhesive layer is provided on the back surface of a water-absorbing material, and is adhered to a place where dew condensation occurs to absorb dew condensation.
However, it is difficult to confirm whether or not the dew condensation absorbing sheet is in a state of absorbing dew condensation, and there is a problem that it is difficult to determine the necessity of ventilation while being poor in detectability.

本発明は、前記従来の結露吸収シートの不具合を解消しようとするものであって、即ち、結露を吸収した状態を簡易に判別可能であり、よって、換気の必要性を判断し易い可逆変色性結露吸収テープを提供するものである。   The present invention is intended to solve the problems of the conventional condensation-absorbing sheet, that is, it is possible to easily determine the state in which condensation has been absorbed, and thus it is easy to determine the necessity of ventilation. Condensation absorbing tape is provided.

本発明は、片面に粘着層を設けた吸水保持力が200〜800g/m の布帛からなる水分吸収材の非粘着層側の表面に、低屈折率顔料をバインダー樹脂に分散状態に固着させた、非吸水状態で不透明であり、吸水状態で透明化する多孔質層を設けてなる可逆変色性結露吸収テープを要件とする。
更には、前記水分吸収材表面の多孔質層を設けた部分と設けていない部分の面積比が0.5:99.5〜50:50であること、前記布帛がナイロン樹脂とポリエステル樹脂とからなる分割型複合繊維により形成されてなること、前記粘着層が水不溶性であること、水分吸収材と多孔質層の間に着色層を設けてなること等を要件とする。
In the present invention, a low refractive index pigment is fixed to a binder resin in a dispersed state on the non-adhesive layer side surface of a moisture absorbent material comprising a fabric having an adhesive layer provided on one side and a water absorption retention of 200 to 800 g / m 2. Further, a reversible color-changeable dew-absorbing tape provided with a porous layer that is opaque in a non-water-absorbing state and transparent in a water-absorbing state is a requirement.
Furthermore, the area ratio of the porous layer provided part and provided no portion of the water absorbent surface 0.5: 99.5 to 50: it is a 50, before Symbol fabric nylon resin and a polyester resin the split is formed by composite fibers comprising consisting, before SL adhesive layer be water insoluble and such a requirement to be formed by providing a colored layer between the moisture absorbing material and the porous layer.

Can be provided.

前記水分吸収材は結露の吸収性と蒸発性(乾燥性)を有する織物、編物、組物、不織布等の布帛を平面状水分吸収材として用いる
なお、耐久性と剥離性の観点から水分吸収材としては布帛が好適であり、綿、麻、絹、ウール、パルプ、レーヨン、ナイロン、ビニロン、アクリル、ポリエステル、ポリプロピレン、ポリエチレン繊維等を例示でき、これらの繊維は一種用いてもよく、二種以上を組み合わせて用いてもよい。
前記布帛のうち、ナイロン樹脂とポリエステル樹脂とからなる分割型複合繊維が好適であり、結露の吸収性と、乾燥性の両性能を十分に満たすことができる。
前記布帛は吸水保持力が200〜800g/mである。吸水保持力が200g/m未満では結露を十分に吸収することができず、吸収されなかった結露が窓枠、床、カーテン等を濡らして黴や汚れを発生させ易くなる。また、吸水保持力が800g/mを超えると吸収した結露が蒸発し難く、布帛自体に黴や汚れを発生し易くなると共に、換気の必要性を判断することができなくなる。
なお、前記吸水保持力は、JIS L1018B法により、水を含浸させた布帛を吊干し、2分後の保水率(%)を算出した後、該保水率に布帛の目付け量(g/m)を乗じて求める。
The moisture absorbing material is absorbing the evaporative (drying) the Yusuke that woven of condensation, knitting, plaiting, using fabric such as a nonwoven fabric as a flat planar moisture absorbing material.
In addition, from the viewpoint of durability and releasability, a fabric is suitable as a moisture absorbing material, and examples include cotton, hemp, silk, wool, pulp, rayon, nylon, vinylon, acrylic, polyester, polypropylene, polyethylene fiber, These fibers may be used alone or in combination of two or more.
Among the fabrics, a split type composite fiber made of a nylon resin and a polyester resin is suitable, and can sufficiently satisfy both the dew absorbability and the drying performance.
The fabric has a water absorption retention of 200 to 800 g / m 2 . If the water absorption holding power is less than 200 g / m 2 , the condensation cannot be sufficiently absorbed, and the condensation that has not been absorbed easily wets the window frame, the floor, the curtain, etc., and tends to cause wrinkles and dirt. Further, if the water absorption holding power exceeds 800 g / m 2 , the absorbed dew condensation is difficult to evaporate, and it becomes easy to generate wrinkles and dirt on the fabric itself, and the necessity of ventilation cannot be determined.
The water-absorbing retention strength is determined by hanging a fabric impregnated with water according to JIS L1018B method, calculating a water retention rate (%) after 2 minutes, and then calculating the fabric weight per unit weight (g / m 2). ).

前記水分吸収材表面に設けられる多孔質層は、低屈折率顔料をバインダー樹脂と共に分散状態に固着させた層であり、乾燥状態と結露を吸収した吸液状態で透明性が異なる層である。

なお、前記珪酸の塩としては、珪酸アルミニウム、珪酸アルミニウムカリウム、珪酸アルミニウムナトリウム、珪酸アルミニウムカルシウム、珪酸カリウム、珪酸カルシウム、珪酸カルシウムナトリウム、珪酸ナトリウム、珪酸マグネシウム、珪酸マグネシウムカリウム等が挙げられる。
又、前記低屈折率顔料は2種以上を併用することもできる。
The porous layer provided on the surface of the moisture absorbing material is a layer in which a low refractive index pigment is fixed in a dispersed state together with a binder resin, and is a layer having different transparency in a dried state and a liquid absorbing state in which condensation is absorbed.
Examples of the low refractive index pigment include silicic acid and salts thereof, barite powder, barium sulfate, barium carbonate, calcium carbonate, gypsum, clay, talc, alumina white, magnesium carbonate, and the like. It is in the range of 1.8, and shows good transparency when water is absorbed.
Examples of the silicic acid salts include aluminum silicate, aluminum potassium silicate, sodium aluminum silicate, aluminum calcium silicate, potassium silicate, calcium silicate, calcium sodium silicate, sodium silicate, magnesium silicate, and magnesium potassium silicate.
Two or more of the low refractive index pigments can be used in combination.

前記多孔質層は、一般的な塗膜と比較して着色剤に対するバインダー樹脂の混合比率が小さいため、十分な皮膜強度が得られ難い。そこで、耐擦過強度を高めるために、前記のバインダー樹脂のうち、ナイロン樹脂又はウレタン系樹脂を用いると効果的である。
前記バインダー樹脂において、架橋性のものは任意の架橋剤を添加して架橋させることにより、さらに皮膜強度を向上させることができる。
前記バインダー樹脂には、水との親和性に大小が存在するが、これらを組み合わせることにより、多孔質層中への浸透時間、浸透度合い、浸透後の乾燥の遅速を調整することができる。更には、適宜分散剤や界面活性剤を添加して前記調整をコントロールすることができる。
The low refractive index pigment is dispersed in a vehicle containing a binder resin as a binder, applied to a translucent support, and then the volatile matter is dried to form a porous layer.

Since the porous layer has a smaller mixing ratio of the binder resin to the colorant than a general coating film, it is difficult to obtain sufficient film strength. Therefore, in order to increase the scratch resistance, it is effective to use a nylon resin or a urethane resin among the binder resins.
In the binder resin, the crosslinkable resin can be further improved in film strength by adding an arbitrary crosslinking agent and crosslinking.
The binder resin has a large or small affinity with water. By combining these, the penetration time into the porous layer, the degree of penetration, and the slow speed of drying after the penetration can be adjusted. Furthermore, the said adjustment can be controlled by adding a dispersing agent and surfactant suitably.

In the normal state (non-water-absorbing state), the dew-absorbing tape allows a porous layer made of a white floral pattern to be visualized on a pink fabric. A pink appearance is visible. In the water-absorbing state, the entire surface was kept in a pink state, but as it dries, it gradually returns to the state in which a white floral pattern is printed on the original pink base, and the above-mentioned change in appearance can be reproduced repeatedly. It was.
When the release paper is removed from the dew condensation absorbing tape and attached to the room side of the glass window, the dew generated on the glass window is absorbed, and the white floral pattern gradually fades from the top. Furthermore, the color changed from the upper part to the lower part by absorbing the condensation.

In the normal state (non-water-absorbing state), the dew-absorbing tape allows a porous layer composed of a white star pattern to be visually recognized on a white fabric. However, when water is sprayed, the porous layer becomes transparent due to liquid absorption, and a blue star is formed. The handle is visible. Although the blue star pattern was maintained in the water absorption state, it gradually returned to the original white star pattern as it dried, and the above-mentioned change in appearance could be reproduced repeatedly.
Remove the release paper from the condensation absorption tape and stick it to the room side of the glass window.It absorbs the condensation generated on the glass window and gradually changes to a blue star pattern from the top.
