High-temperature ceramic blocking fireproof door sealing strip
The invention discloses a high-temperature ceramic blocking fireproof door sealing strip. The sealing strip is mainly formed by mixing and hot-pressing rubber, inorganic powder, thermal expansion microspheres and additives. Wherein the inorganic powder comprises at least one of aluminum-containing inorganic powder, titanium-containing inorganic powder, magnesium-containing inorganic powder and silicon-containing inorganic powder; wherein the mass ratio of the rubber to the inorganic powder is 1: 1-3: 1, the use amount of the thermal expansion microspheres is 1-5wt% of the use amount of the inorganic powder, and the use amount of the additive does not exceed 10wt% of the use amount of the inorganic powder. The porous ceramic is formed by mixing inorganic powder containing aluminum, titaniumand the like with the thermal expansion microspheres and sintering at high temperature, the air tightness of the sealing strip is improved to block a fire source by utilizing the porous ceramic structure, and the sealing strip has excellent fireproof performance.
本发明公开了一种高温陶瓷阻断防火门密封条，所述密封条主要由橡胶、无机粉末、热膨胀微球、添加剂经过混炼、热压而成；所述无机粉末包括含铝无机粉末、含钛无机粉末、含镁无机粉末、含硅无机粉末中的至少一种；按质量比计，所述橡胶与无机粉末的用量比为1∶1～3∶1，所述热膨胀微球的用量为所述无机粉末用量的1～5wt.％，所述添加剂的用量不超过所述无机粉末用量的10wt.％。本发明通过将含铝、钛等无机粉末与热膨胀微球进行混合，高温下烧结形成多孔陶瓷，利用多孔陶瓷结构，增加密封条的气密性阻断火源，具备优异的防火性能。
