Description
【考案の詳細な説明】 本考案は石こう板の構造に関するものである。[Detailed explanation of the idea] The present invention relates to the structure of a gypsum board.
さらに詳しくは、ガラス繊維などの補強繊維を含有する

削し起毛層３，３′を設けた石こう板の構造である。More specifically, synthetic fiber or glass fiber nonwoven fabrics 2 and 2 are formed on both sides of a foamed or non-foamed gypsum board 1 containing reinforcing fibers such as glass fibers so as to be integrated with the iron gypsum board.
This is a gypsum board structure in which raised layers 3 and 3' are formed by laminating layers of non-woven fabrics and then thinly grinding the surface of the nonwoven fabric using a sander or the like.
一般に石こう板又は石こうボードは成形特にボード厚紙
と称せされる成形厚紙が用いられ、その成形内部にスラ
リー状の石こう配合物が注入されるが、この厚紙は厚さ
も０．８〜１．Ｑｍｍと厚くしかも組織的に緻密である
ため、スラリー中に含まれる過剰水分の滲出・排出が不
可能である。Generally, a gypsum board or a gypsum board is formed by molding, particularly a molded cardboard called board cardboard, into which a slurry-like gypsum compound is injected, and this cardboard has a thickness of 0.8 to 1 mm. Since it is as thick as Qmm and has a dense structure, it is impossible for excess water contained in the slurry to ooze out or be discharged.
特にガラス繊維等の無機質繊維を補強繊維として混入し
、かつスラリー中に微細な空気泡を混入した発泡石こう
配合物の場合は、ガラス繊維の均一分散と気泡の均一混
入のために通常の非気堆石こうの場合よりも多量の水分
を添加した配合物を用いる。In particular, in the case of a foamed gypsum compound in which inorganic fibers such as glass fibers are mixed as reinforcing fibers and fine air bubbles are mixed into the slurry, ordinary non-air-filled gypsum compounds are used to ensure uniform dispersion of glass fibers and uniform inclusion of air bubbles. A formulation with a higher amount of water added than in the case of mortar is used.
かかる配合物では、板状に成形した後いかに早く過剰水
分を排出させるかが決め手となるが、前記の厚紙ではそ
の排出が不可能か非常に遅く、そのため作業性を著しく
悪くするという欠点があった。For such compounds, the deciding factor is how quickly excess water can be drained off after being formed into a plate shape, but with the above-mentioned cardboard, this draining is either impossible or very slow, and this has the disadvantage of significantly impairing workability. Ta.
本考案の場合はこの厚紙に代えて、厚さが約０．４ｍｍ
坪量６０ｇ／ｍ２の比較的薄手のポリエステル繊維不織
布を用いる。In the case of this invention, instead of this cardboard, the thickness is about 0.4 mm.
A relatively thin polyester fiber nonwoven fabric with a basis weight of 60 g/m2 is used.
ポリエステル繊維不織布の場合は、注入と同時に配合物
の自重による緊縮により過剰水分の排出が行われるめで
厚紙の場合と異なり、作業性が極めて良く連続生産が可
能となる。In the case of polyester fiber nonwoven fabric, excess moisture is discharged simultaneously with injection due to contraction due to the compound's own weight, and unlike in the case of cardboard, workability is extremely good and continuous production is possible.
石こうスラリー注入後、その上面に同様の不織布を積層
することにより所定の石こう板が得られるが、この場合
不織布中にスラリーが浸入し石こう部との積層が一体的
となり、強度にすぐれた製品が得られる。After injecting the gypsum slurry, a similar nonwoven fabric is laminated on top of the gypsum slurry to obtain a desired gypsum board. In this case, the slurry penetrates into the nonwoven fabric and the gypsum part becomes integrated with the gypsum part, resulting in a product with excellent strength. can get.
不織布はポリエステル繊維製の代りにガラス繊維製不織
布も有効である。Instead of polyester fiber nonwoven fabric, glass fiber nonwoven fabric is also effective.
本考案の石こう板の場合は、このポリエステル繊維不織
布２．２′の表面をサンダー等によって薄く研削するこ
とにより合成繊維による起毛層３，３′を設ける。In the case of the gypsum board of the present invention, the raised layers 3, 3' made of synthetic fibers are provided by thinly grinding the surface of the polyester fiber nonwoven fabric 2, 2' with a sander or the like.
この起毛層の存在は極めて有効な作用効果を発揮する。The presence of this raised layer exhibits extremely effective effects.
即ち、石こう層１に巨大気泡が混入してその部分がガラ
ス繊維不織２，２′を通して透視出来る場合であっても
サンダーがけをし、不織布に含まれる石こう分を均一に
沈積させるのと同時に合成繊維の起毛層を設けることに
より、この透けた泡跡がポカされて目立たなくなりすぐ
れた外観を有する石こう板が得られる。That is, even if giant bubbles are mixed into the gypsum layer 1 and the bubbles can be seen through the glass fiber nonwovens 2 and 2', sanding is performed to uniformly deposit the gypsum contained in the nonwoven fabric. By providing a raised layer of synthetic fibers, these transparent bubble traces are absorbed and become less noticeable, resulting in a gypsum board with an excellent appearance.
また、該起毛層３，３′が存在することにより石こう板

仕上げの場合は塗料と石こう板との喰いつきが良くなり

されているので塗料の伸びが良く塗装ムラもすぐなくな
る。In addition, due to the presence of the raised layers 3 and 3', when finishing the gypsum board with paint etc., especially in the case of plaster finishing, the paint and the gypsum board have good adhesion, and when sanding the gypsum board Since the surface is evenly leveled, the paint spreads well and unevenness disappears quickly.
本考案の石こう板は上記の如き構造のものであるため製
造工程の合理性のみならず間仕切り材、壁面材とした場
合の塗装適性の極めてすぐれたものであった。Since the gypsum board of the present invention has the above-mentioned structure, it is not only rational in the manufacturing process but also extremely suitable for painting when used as a partition material or wall material.
