【発明の詳細な説明】
本発明は表面が硬く、かつ、弾力性を有する強化石こう
の製造法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing reinforced gypsum having a hard and elastic surface.
従来、石こうは建材等の材料、または成型材料として、
広く一般に使用されているが、硬化した石こう成型物は
弾性がなく、もろく、崩壊し易く、とくに耐衝撃性に乏
しいという欠点があり、これがためその用途に大きな制
約があった。Traditionally, gypsum has been used as a building material or as a molding material.
Although widely used, cured gypsum moldings have the drawbacks of being inelastic, brittle, and easily disintegrating, and particularly having poor impact resistance, which has severely limited their use.
本発明は上記の欠点を解消し、強度が大きく、かつ、弾
力性のある強化石こうの製造法を提供することを目的と
するものである。本発明に係る強化石こうの製造法の要
旨は、半水石こう粉末に、酒石酸、コハク酸の鉄塩また
は３価のアルミニウムからなる金属塩の１０％溶液と、
１〜３％のペントナィト溶液とを適量加え、均一燈拝し
た後成型固化したものである。The object of the present invention is to eliminate the above-mentioned drawbacks and to provide a method for producing reinforced gypsum having high strength and elasticity. The gist of the method for producing reinforced gypsum according to the present invention is to add a 10% solution of a metal salt consisting of tartaric acid, iron salt of succinic acid, or trivalent aluminum to hemihydrate gypsum powder,
A suitable amount of 1 to 3% pentonite solution was added, uniformly heated, and then molded and solidified.
このようにして製造した強化石こうは、表面がきわめて
平滑で、かつ、硬度が大であり、内部は膨潤化した石こ
うで充満され、適度の弾力性を有しており、衝撃等に対
しても容易に破損しないものである。The reinforced gypsum produced in this way has an extremely smooth surface and high hardness, and the interior is filled with swollen gypsum and has moderate elasticity, making it resistant to impacts. It is not easily damaged.
しかも、石こう全体の比重は０．３〜０．４と軽く耐火
性も大である。Furthermore, the specific gravity of the gypsum as a whole is 0.3 to 0.4, which is light and has high fire resistance.
本発明に係る製造法により、このようなすぐれた特長を
有する強化石こうが得られる理由は、詳細は不明である
が、半水石こうに酒石酸、コハク酸の１種からなる鉄塩
もしくは３価アルミニウムからなる金属塩の溶液を混入
すると、この両者が複雑な化学反応を起こして膨潤化し
つつ、硬化する。The reason why reinforced gypsum with such excellent features can be obtained by the production method according to the present invention is not clear in detail, but the reason why reinforced gypsum with such excellent features can be obtained is that iron salt consisting of one of tartaric acid and succinic acid or trivalent aluminum is added to hemihydrate gypsum. When mixed with a solution of metal salts, the two undergo a complex chemical reaction, causing swelling and hardening.
そしてこの際、石こう中に均一に分散しているペントナ
ィトのコロイド粒子が、水分を保有したまま石こうの固
化した組織中に残存し、かつ、石こう分子と化学的に結
合して堅牢、繊密な組織を形成するためであると考えら
れる。次に本発明に係る強化石こうの製造法の実施例に
ついて説明する。At this time, the pentonite colloidal particles uniformly dispersed in the gypsum remain in the solidified structure of the gypsum while retaining water, and chemically combine with the gypsum molecules to form a solid and delicate structure. It is thought that this is to form an organization. Next, an example of the method for manufacturing reinforced gypsum according to the present invention will be described.
〔実施例 １〕
酒石酸第１鉄 １０％溶液 ５の重量部ペン
トナィト ３％溶液 ５の重量部半水石こう
粉末 ４０〜１０の重量部上記３成分を
損梓混合し、注型し、硬化させた。[Example 1] Ferrous tartrate 10% solution 5 parts by weight Pentonite 3% solution 5 parts by weight Hemihydrate gypsum powder 40 to 10 parts by weight The above three components were mixed together, cast, and hardened. .
出来上った強化石こうは比重０．３ふ表面が硬質な陶器
状の平滑面であり、若干の可操性を有したものであった
。The resulting reinforced gypsum had a specific gravity of 0.3 ft, a hard ceramic-like smooth surface, and had some maneuverability.
