    • The present invention relates to a mineral hydrate insulation material which is made of natural minerals and is not harmful to a human body and the environment, wherein multiple functions including the improvement of high insulation, lightweight, fire resistance, and durability properties can be expressed. A method for producing a mineral hydrate insulation material according to a preferable embodiment of the present invention comprises the steps of: (a) pulverizing quartzite and ordinary Portland cement (OPC); (b) producing slurry including 125-135 parts by weight of mixed water, 0.05-0.15 parts by weight of polydimethyl siloxane as an additive, and 0.03-0.1 parts by weight calcium chloride as an additive to control the size of average pores in a mixed powder based on 100 parts by weight of the mixed powder, wherein the mixed powder containing 50-60 wt% of pulverized OPC, 25-35 wt% of pulverized quartzite, 10 wt% of quicklime, and 5 wt% of anhydrous gypsum, and the slurry is maintained within a temperature of 0 to 50°C inclusive; (c) molding a molded product by mixing 0.3-0.5 wt% of a foaming agent with the slurry based on 100 wt% of the mixed powder; (d) adding the molded product in a thermo-hygrostat having 50°C and relative humidity of 50% and aging the same for 4-6 hours; and (e) hydrothermally synthesizing the same at 160-180°C for 3-5 hours using an autoclave.
    • 本发明涉及一种矿物水合物绝缘材料,其由天然矿物制成并且对人体和环境无害,其中可以表现出包括提高高绝缘性,轻质,耐火性和耐久性的多种功能。 根据本发明的优选实施方案的矿物水合物绝缘材料的制造方法包括以下步骤:(a)粉碎石英岩和普通硅酸盐水泥(OPC); (b)制备包含125-135重量份混合水,0.05-0.15重量份作为添加剂的聚二甲基硅氧烷和0.03-0.1重量份氯化钙作为添加剂的浆料,以控制一个平均孔的尺寸 基于100重量份的混合粉末的混合粉末,其中含有50-60重量%的粉碎OPC,25-35重量%的粉碎石英岩,10重量%的生石灰和5重量%的无水石膏的混合粉末, 并将浆液保持在0〜50℃的温度范围内; (c)通过将0.3-0.5重量%的发泡剂与基于100重量%的混合粉末的浆料混合来模制成型产品; (d)将成型品加入到50℃,相对湿度为50%的恒温恒湿器中,老化4-6小时; 和(e)使用高压釜在160-180℃水热合成3-5小时。
