High-fire-resistance low-heat-conduction composite material
The invention discloses a high-fire-resistance and low-heat-conduction composite material which comprises the following components in percentage by volume: 40-72% of hollow silicon-aluminum foaming fire-resistant granules, 25-40% of cementing material and 3-6% of silicon fiber, and the absolute volume ratio of the hollow silicon-aluminum foaming fire-resistant granules is 40-72%, the absolute volume ratio of the cementing material is 25-40%, and the absolute volume ratio of the silicon fiber is 3-6%. The hollow silicon-aluminum foaming fire-resistant granules, the cementing material and the silicon fibers are formed by wet-type mixing or dry-type extrusion, and the hollow silicon-aluminum foaming fire-resistant granules, the cementing material and the silicon fibers form the fire-resistant component. According to the present invention, the hollow silicon-aluminum foaming fire-resistant particle material, the cementing material and the silicon fiber are formed according to the absolute volume ratio, and the hollow silicon-aluminum foaming fire-resistant particle material and the silicon fiber are cemented by the cementing material after the wet-type mixing or the dry-type extrusion molding so as to form the discontinuous porous property and block the heat conduction path, such that the characteristics of high temperature resistance and low back temperature are provided; and radiation propagation of accumulated heat in a fire scene can be effectively blocked.
本发明公开了高耐火低热传导复合材料，包括中空硅铝发泡耐火粒料、胶结料和硅纤维，中空硅铝发泡耐火粒料的绝对体积比为40～72％，胶结料的绝对体积比为25～40％，硅纤维的绝对体积比3～6％，中空硅铝发泡耐火粒料、胶结料和硅纤维利用湿式拌合或者干式挤压成型，中空硅铝发泡耐火粒料、胶结料硅纤维组成耐火构件。本发明通过由中空硅铝发泡耐火粒料、胶结料和硅纤维按绝对体积比所组成，利用湿式拌合或者干式挤压成型后，该胶结料将中空硅铝发泡粒料及硅纤维胶结住，会形成不连续多孔性质，阻绝热传导路径，因而具有耐高温及背温低的特性，可有效阻隔火场内聚积热的辐射传播。
