【発明の詳細な説明】 この発明は無機硬化体の製造方法に関するものである。[Detailed description of the invention] This invention relates to a method for producing an inorganic cured body.
従来、カルシウムアルミネートトリサルフェートハイド
レート（３ＣａＯ” Ａｔ２０３” ３ＣａＳＯ＋”３
１〜３２Ｈ２０、以下ＴＳＨと略す）を主成分とする無
機硬化体は、つぎのようにしてつくられていた。Conventionally, calcium aluminate trisulfate hydrate (3CaO"At203"3CaSO+"3
An inorganic cured body containing 1-32H20 (hereinafter abbreviated as TSH) as a main component was produced in the following manner.
すなわち、カルシウムアルミネートモノサルフェートハ
イドレート（３ＣａＯ−Ａｔ２０３・ＣａＳＯ４・１２
Ｈ２０、以下Ｍ Ｓ Ｈと略す）に、石こう（Ｃａ５Ｏ
＋ ’ ２ Ｈ２Ｏ、Ｃａ５Ｏ＋ ６１ ／ ２Ｈ２０
Ｃａｎｏｅ）と水とを加えて反応させて製造する。That is, calcium aluminate monosulfate hydrate (3CaO-At203・CaSO4・12
H20 (hereinafter abbreviated as MSH), gypsum (Ca5O
+ '2 H2O, Ca5O+ 61/2H20
Canoe) and water are added and reacted to produce it.
このようにして得られたＴＳＨ硬化体は、主として建築
用材として用いられているが、強度をより大きくするこ
とができれば一層建築用材としての価値が高くなる。The thus obtained cured TSH body is mainly used as a building material, but if its strength can be increased, its value as a building material will be even higher.
したがって、この発明の目的は、強度の一層大きい無機
硬化体の製造方法を提供することである。Therefore, an object of the present invention is to provide a method for producing an inorganic cured product with higher strength.
要約すれば、この発明の製造方法は、ＭＳＨと石こうと
水とを混合して粒状体を形威し、この粒状体を高分子物
質で被覆し、これを加圧して所望の形状に賦形したのち
養生することを特徴とするものである。In summary, the manufacturing method of the present invention involves mixing MSH, gypsum, and water to form granules, coating the granules with a polymeric material, and pressurizing the granules to shape them into a desired shape. It is characterized by the fact that it is then cured.
その結果、養生中に被覆粒状体内でＭＳＨと石こうと水
とが反応してＴＳＨになり硬化膨張する。As a result, during curing, MSH, gypsum, and water react within the coated granules to form TSH, which hardens and expands.
そのため、被覆粒状体が膨張し相互に強固に密着して硬
化体の強度が著しく大きくなる。Therefore, the coated granules expand and adhere firmly to each other, significantly increasing the strength of the cured product.
また、一般にＴＳＨ硬化体は、炭酸ガスにより分解され
て強度低下を招来するが、この発明の方法では、それを
高分子物質で被覆しているため、そのようなことが生じ
ない。Further, generally, a TSH cured product is decomposed by carbon dioxide gas, resulting in a decrease in strength, but in the method of the present invention, since it is coated with a polymeric substance, such a problem does not occur.
また、生成した無機硬化体を切断しても、ＴＳＨ硬化体
が被覆されているため、内部まで炭酸ガスによる影響を
受けない。Furthermore, even if the produced inorganic cured body is cut, the inside thereof will not be affected by carbon dioxide gas because the TSH cured body is coated.
つぎに、この発明の詳細な説明する。Next, this invention will be explained in detail.
粒状体の形成は、例えばペレツテングマシンにより行な
うことができる。Formation of the granules can be carried out, for example, using a pelletizing machine.
高分子物質としては、例えばポリアクリル酸、カゼイン
、ポリアミノカルボン酸系のキレート樹脂等が用いられ
る。As the polymer substance, for example, polyacrylic acid, casein, polyaminocarboxylic acid-based chelate resin, etc. are used.
つきに、実施例について説明する。Examples will now be described.
実施例 １〜５
ＭＳＨと石こうと水とをＴＳＨ生成モル比に選んで混合
し、これをペレツテングーｌシンで粒状体にした。Examples 1 to 5 MSH, gypsum, and water were mixed at a molar ratio selected to produce TSH, and the mixture was made into granules using pellets.
この場合、遅延剤を添加して反応をコントロールした。In this case, a retarder was added to control the reaction.
つぎに、この粒状体を次表に示す高分子物質で被覆して
被覆粒状体にし、これをプレス（プレスモ２０ ｋｇ／
ｃｒｒｔ ） ｌ、て賦形し、５０℃で養生して４０℃
で乾燥し、次表に示す密度を有する無機硬化体を得た。Next, this granule is coated with a polymeric substance shown in the following table to form a coated granule, which is then pressed using a press (Presmo 20 kg/
crrt) l, molded, cured at 50℃, and heated to 40℃
An inorganic cured product having a density shown in the following table was obtained.
このようにして得た無機硬化体について、従来の方法で
製造した無機硬化体を対照用として性能試１験を行なっ
た。A performance test was conducted on the thus obtained inorganic cured body using an inorganic cured body produced by a conventional method as a control.
その結果を次表に示す。The results are shown in the table below.
上記の表から明らかなように、この発明の方法によれば
、得られた無機硬化体の曲げ強度は、従来のものに比べ
て２０％大きくなり、かつ炭酸化速度が１／１０程度に
なる。As is clear from the above table, according to the method of the present invention, the bending strength of the obtained inorganic cured product is 20% higher than that of the conventional method, and the carbonation rate is about 1/10. .
