The invention discloses a silicon-containing flame-retardant foot pad for an automobile and a preparation method of the silicon-containing flame-retardant foot pad, and relates to the technical field of foot pads. The needle-punched cloth is modified, and the flame-retardant property of the foot pad is enhanced by using the flame-retardant microcapsules. Iron oxide and silicon dioxide are compounded, the dispersity of silicon dioxide is enhanced, then the surface of silicon dioxide is wrapped with polypyrrole, the microcapsule is further prepared, the microcapsule can generate phosphorus-containing and nitrogen-containing groups during combustion, the char forming capacity is improved, and therefore the thermal stability and the carbon residue barrier property are enhanced; therefore, the escape of harmful gas is further inhibited, and the flame-retardant property of the silicon-containing flame-retardant foot pad is enhanced. The surface of the foot pad is also coated with a flame-retardant coating, so that the flame retardance of the foot pad is further enhanced.
本发明公开了一种汽车用含硅阻燃脚垫及其制备方法,涉及脚垫技术领域。本发明对针刺布进行改性,使用阻燃微胶囊增强了脚垫的阻燃性能。本发明将氧化铁与二氧化硅复合,增强了二氧化硅的分散性,然后在其表面包裹聚吡咯,将其进一步制备为微胶囊,该微胶囊在燃烧时会产生含磷、含氮基团,改善成炭能力,从而增强热稳定性和残炭的阻隔性能,从而进一步抑制有害气体的逸出,增强含硅阻燃脚垫的阻燃性能。本发明还在脚垫的表面涂布了阻燃涂料,进一步增强了脚垫的阻燃性。
