この発明は、住宅等の落第構造に使用される蓄熱建材に
関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a heat storage building material used in a failing structure of a house or the like.

熱蓄熱材が、特に注目されている。BACKGROUND ART Conventionally, a heat storage structure has been adopted in the openings and floors of a room using a sensible heat storage material such as concrete or water, or a latent heat storage material such as an inorganic hydrate salt, paraffin, or polyalcohol. Among these, polyalcohol photothermal storage materials that have a large amount of heat storage per unit amount and utilize solid phase transition (transition heat) are attracting particular attention.

、水に溶けると潜熱蓄熱材としての特性が無くなってし
まうというものであった。This polyalcohol-based latent heat storage material is an excellent heat storage material, but it is hygroscopic and easily dissolves in water, and when it dissolves in water, it loses its properties as a latent heat storage material. there were.

移を起こしにくくなるという欠点があった。For this reason, even if a polyalcohol-based latent heat storage material is dispersed in building materials such as gypsum board, it will absorb moisture when the humidity is high, melt and seep out onto the surface of the building material, resulting in sticky residue or solid phase transition. The disadvantage was that it became difficult.

熱建材を要旨とする。In view of these circumstances, the present invention aims to provide a heat storage building material in which the polyalcohol latent heat storage material dispersed in the building material body always maintains a stable state and always exhibits a stable heat storage effect. [Disclosure of the Invention] In order to achieve the above object, the present invention contains polyalcohol-based WIF4'? The gist is a heat storage building material in which M thermal material is dispersed and the surface of the main body is impregnated with paraffin having a melting point higher than the operating temperature of the building material.
以下に、この発明の詳細な説明する。The present invention will be explained in detail below.
建材本体としては、石膏ボードが挙げられる。Examples of the building material itself include gypsum board.
ポリアルコール系潜熱蓄熱材（以下に、「蓄熱材」との
み称する）としては、ネオペンチルグリコール、ペンタ
グリセリン、ペンタエリスリ１−一ル等の、建材の使用
温度域に固相転移点を有するものが挙げられる。Polyalcohol-based latent heat storage materials (hereinafter simply referred to as "thermal storage materials") include those that have a solid phase transition point in the temperature range in which building materials are used, such as neopentyl glycol, pentaglycerin, and pentaerythritol. Can be mentioned.
つぎに、この蓄熱建材の製法をその工程の順に詳しく説
明する。Next, the manufacturing method of this heat storage building material will be explained in detail in the order of the steps.

ド中で固相転移できるようになる。First, instead of water, an aqueous solution of the heat storage material described above is added to a base material such as gypsum, kneaded, and then molded into a boat and hardened. In addition, when the base material is gypsum, the blending ratio of the heat storage material is set to 40% by weight or less based on the gypsum. This is because when the dispersion 9 of the heat storage material is large, the amount of heat storage increases and it becomes a good heat storage building material, but when it is more than 40% by weight, the gypsum becomes difficult to harden. Next, this hardened board (main body of the building material) is dried to evaporate moisture, and the heat storage material is solidified in a dispersed state within the board. The solidified heat material can undergo a solid phase transition in the board.

ない。普通は２０〜３０重量％くらいである。Paraffin having a melting point higher than the maximum temperature at which the building material is used for heat storage is melted, and this melted liquid is impregnated into the voids that are created after the moisture of the board in which the heat storage material is dispersed has evaporated, and then hardened. . As mentioned above, paraffin has a melting point higher than the operating temperature of the building material, so it does not liquefy during use, and it always tightly covers the board surface, and the heat storage material in the board absorbs the effects of moisture in the outside air. As a result, it does not lose its latent heat storage ability and does not seep out to the surface. Method for dispersing heat storage material into board 1 Alternatively, the board may be formed in advance, impregnated with an aqueous solution or melt of the heat storage material, and then dried. Even in this method, if the board is a gypsum board, it is impossible to disperse more than 40% by weight due to its porosity. Usually it is about 20 to 30% by weight.
