Abstract

<P>PROBLEM TO BE SOLVED: To provide wallpaper made of a paper raw material and has more functions than those of conventional wallpaper. <P>SOLUTION: This wallpaper is made of a paper raw material and contains the powder of silica having a purity of 99.8% or more. The particle diameter is preferably 0.4-0.6 μm, and the content of the silica is preferably 30-50 wt.% based on the paper raw material. Since containing the silica, the wallpaper has excellent heat resistance, and since the silica has low heat conductivity, the wallpaper does not let the temperature of air in the room to escape. Since the silica reflects light, the paper raw material does not fade away. Since the powder of the silica is porous and has a large specific surface area, the powder of the silica has high adsorbability, good deodorizing effect, good air-cleaning effect, and good antibacterial effect. Since having good air permeability, the powder of the silica can prevent dew condensation. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

本発明は、純度の高いシリカ（ＳｉＯ_２）の粉末を含有することで種々の機能を付与した壁紙に関する。 The present invention relates to a wallpaper having various functions provided by containing high-purity silica (SiO ₂ ) powder.

従来、住宅などの壁仕上げに用いられる壁紙に、和紙を始めとする紙素材が用いられている。紙素材の壁紙は、通気性が良好であること、色や柄が豊富なこと、環境にやさしいことなどの特徴を有する。しかし、ビニール壁紙などで一般的な、抗菌性や消臭性などの機能を付与したいわゆる機能性壁紙は、あまり存在しなかった。そこで、文献１および２において、紙にシリカやアルミナなどの粉末を混合したものを含有させまたは塗被させた障子紙や壁紙が提案されている。
実開平４−７６９８号公報実開平１−１１０３００号公報 Conventionally, paper materials such as Japanese paper are used for wallpaper used for wall finishing in houses and the like. Paper-based wallpaper has features such as good air permeability, rich colors and patterns, and environmental friendliness. However, there are few so-called functional wallpapers that have functions such as antibacterial and deodorizing properties that are common in vinyl wallpaper. Therefore, Documents 1 and 2 propose shoji paper and wallpaper in which paper is mixed or coated with a powder of silica, alumina, or the like.

ここで、文献１の発明は、空気の清浄化という効果を有し、文献２の発明は、遠赤外線を輻射することで人体の健康を増進するという効果を有するものであるが、紙素材以外の壁紙と比較すると、充分な機能が付与されているとはいえなかった。 Here, the invention of Document 1 has an effect of cleaning air, and the invention of Document 2 has an effect of promoting the health of the human body by radiating far infrared rays. Compared with no wallpaper, it could not be said that sufficient functions were given.

本発明は、上記事情を鑑みたものであり、従来のものと比べてさらに多くの機能を付与した紙素材の壁紙を提供することを目的とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a paper wallpaper having more functions than those of conventional ones.

本発明のうち請求項１の発明は、紙素材からなり、純度が９９．８％以上のシリカの粉末を含有することを特徴とする。 The invention of claim 1 among the present invention is characterized in that it is made of a paper material and contains silica powder having a purity of 99.8% or more.

また、請求項２の発明は、前記シリカの粒子径が、０．４μｍ〜０．６μｍであることを特徴とする。 The invention of claim 2 is characterized in that a particle diameter of the silica is 0.4 μm to 0.6 μm.

さらに、請求項３の発明は、前記シリカの含有率が、紙素材に対して３０ｗｔ％〜５０ｗｔ％であることを特徴とする。 Furthermore, the invention of claim 3 is characterized in that the silica content is 30 wt% to 50 wt% with respect to the paper material.

本発明によれば、高純度のシリカを含有させることにより、紙素材でありながら耐熱性に優れる。また、シリカは熱伝導率が低いため、夏は室内の冷房の冷気を逃がさず外の熱気を遮断し、冬は室内の暖房の暖気を逃がさず外の冷気を遮断する効果がある。さらに、シリカが光を反射するため、紙素材が色あせしない。また、シリカの粉末は多孔質で比表面積が大きいことから吸着性が高く、消臭効果、空気を清浄化する効果および抗菌効果を有し、通気性が良好であるため、結露を防止することができる。 According to the present invention, by including high-purity silica, the paper material is excellent in heat resistance. In addition, since silica has low thermal conductivity, it has the effect of blocking the outside air without letting the cool air from the room air-conditioning in the summer, and blocking the outside air without letting the warm air from the room heating in the winter. Furthermore, since silica reflects light, the paper material does not fade. Silica powder is porous and has a large specific surface area, so it has high adsorptivity, has a deodorizing effect, an air cleaning effect and an antibacterial effect, and has good air permeability, thus preventing condensation. Can do.

本発明の壁紙の具体的な構成について説明する。本発明は、一般的な紙素材からなる壁紙であって、これに粉末状のシリカを含有させたものである。シリカを含有させる方法としては、紙素材が和紙である場合には、紙をすくための水にシリカの粒子を混ぜておき、その水ですくことにより、紙の全体にわたって均等にシリカを含有させることができる。また、紙素材が洋紙である場合には、原料となるパルプにあらかじめシリカを混ぜておく。ここで、含有させるシリカの量は、紙素材に対して３０ｗｔ％〜５０ｗｔ％であることが望ましい。 A specific configuration of the wallpaper of the present invention will be described. The present invention is a wallpaper made of a general paper material, which contains powdered silica. As a method of containing silica, when the paper material is Japanese paper, the silica particles are mixed with water for scrubbing the paper, and the water is used to mix the silica evenly throughout the paper. be able to. In addition, when the paper material is western paper, silica is mixed in advance with pulp as a raw material. Here, the amount of silica to be included is desirably 30 wt% to 50 wt% with respect to the paper material.

また、上記の方法とは別に、紙素材の表面にシリカの粉末を塗布してもよい。この場合、シリカをスプレーで吹き付ける、あるいは刷毛で塗るなど、どのような手段を用いてもよい。 In addition to the above method, silica powder may be applied to the surface of the paper material. In this case, any means such as spraying silica or painting with a brush may be used.

本発明において用いられるシリカの粉末は、純度が９９．８％以上であり、その粒子径が０．４μｍ〜０．６μｍであることが望ましい。以下の表１に、その組成の分析結果を示す。なお、これはあくまでも組成の一例であり、シリカの純度が９９．８％以上のものであれば、それ以外の成分は異なっていてもよい。

The silica powder used in the present invention preferably has a purity of 99.8% or more and a particle size of 0.4 μm to 0.6 μm. Table 1 below shows the analysis results of the composition. In addition, this is an example of a composition to the last, and as long as the purity of a silica is 99.8% or more, other components may differ.

本発明の壁紙は、上記のとおり９９．８％以上という高純度のシリカを含有していることから、紙素材でありながら耐熱性に優れる。また、シリカは熱伝導率が低いため、本壁紙を施工した壁は断熱性が高められる。よって、夏は室内の冷房の冷気を逃がさず、外の熱気を遮断し、冬は室内の暖房の暖気を逃がさず、外の冷気を遮断する効果がある。また、紙素材は光が当たることで色あせしやすいが、本壁紙の場合、含有するシリカが光を反射するため、紙素材が色あせしない。また、シリカの粉末は多孔質で比表面積が大きいことから吸着性が高く、消臭効果、空気を清浄化する効果および抗菌効果を有し、通気性が良好であるため、結露を防止することができる。 Since the wallpaper of the present invention contains silica of high purity of 99.8% or more as described above, it is excellent in heat resistance while being a paper material. In addition, since the thermal conductivity of silica is low, the wall on which this wallpaper is constructed has improved heat insulation. Therefore, in the summer, there is an effect that the cool air from the indoor cooling is not released and the outside hot air is blocked, and in the winter, the warm air from the indoor heating is not released and the outside cool air is blocked. In addition, the paper material is likely to fade when exposed to light, but in the case of this wallpaper, the silica contained therein reflects the light, so the paper material does not fade. Silica powder is porous and has a large specific surface area, so it has high adsorptivity, has a deodorizing effect, an air cleaning effect and an antibacterial effect, and has good air permeability, thus preventing condensation. Can do.

本発明の壁紙は、通常の紙素材の壁紙とまったく同じように施工することができる。もとより紙素材の壁紙は施工しやすいが、本発明はその施工性を損なわず、新築の建物はもちろん、既存の建物に対しても容易に施工することができる。 The wallpaper of the present invention can be constructed in exactly the same way as a normal paper material wallpaper. Originally, wallpaper made of paper is easy to construct, but the present invention does not impair its construction, and can be easily constructed not only for newly built buildings but also for existing buildings.
