Novel porous composite silicate thermal insulation material and preparation method thereof
The invention discloses a novel porous composite silicate thermal insulation material and a preparation method thereof, and belongs to the technical field of inorganic thermal insulation materials. The material disclosed by the invention is prepared by compounding main materials including soluble fibers and vitrified microbeads with a dispersing agent, an adhesive, a penetrating agent, sepiolite fabric, calcium sulfate whiskers, silicon dioxide and an anti-thermal radiation material. The soluble fibers are used to replace the traditional ceramic fibers, and the soluble fibers have sufficient solubility in the human body fluid, such that the residence time in the human body is shortened, and the damage of the traditional ceramic fibers to the human body is reduced to the minimum. Asbestos is not contained, so that the environment is not polluted. The thermal insulation material prepared by the invention is suitable for thermal equipment of departments such as electric power, petroleum,chemical industry, light industry and national defense industry, transportation, metallurgy and the like, cold (heat) preservation engineering of the inner wall of a chimney and a kiln shell, heat preservation and insulation of pipelines and the like, and has the advantages of environmental friendliness, no toxicity, low heat conductivity coefficient, high temperature resistance, good thermal stability, good mechanical property, convenience in construction and the like.
本发明公开了一种新型多孔复合硅酸盐绝热材料及其制备方法，属于无机保温材料技术领域。本发明材料以可溶性纤维和玻化微珠为主，并加入分散剂、粘结剂、渗透剂、海泡石绒、硫酸钙晶须、二氧化硅、抗热辐射材料复合而成，用可溶性纤维代替传统陶瓷纤维，可溶性纤维在人体体液中有足够的溶解度，缩短在人体内的停留时间，将传统陶瓷纤维对人体的损害降到最低；且不含石棉，不污染环境。本发明制备的绝热材料适用于电力、石油、化工、轻工和国防工业、交通、冶金等部门的热力设备、烟囱内壁和炉窑外壳的保（温）冷工程、管道的保温隔热等，具有环境友好，无毒，导热系数低，耐高温，热稳定性好，力学性能好，施工方便等优点。
