Preparation method of graphene-doped thermal-insulation fireproof material for fireproof door
The invention discloses a preparation method of a graphene-doped thermal-insulation fireproof material for a fireproof door. The preparation method comprises the following steps: carrying out addition reaction on sulfydryl (-SH) of sulfhydrylated graphene and an olefin part of dibutyltin maleate; according to the reaction, more stable thioether bonds are formed through direct addition of sulfydryl and carbon-carbon double bonds; due to the structural change, the interaction between graphene and other components is enhanced, and the thermal stability and flame retardance of the fireproof material are improved; a silicon-hydrogen bond (Si-H) in the 1, 1-bis (dimethylsilyl) iron and an olefin part of the dibutyltin maleate are subjected to an addition reaction; silicon atoms and carbon-carbon double bonds are added in the reaction to form silicon-carbon bonds (Si-C) of ferrocene, so that the structural stability and high temperature resistance of the material are further enhanced; the graphene-doped thermal-insulation fireproof material for the fireproof door, prepared by the preparation method disclosed by the invention, reaches the A1-grade fireproof building material standard.
本发明公开了一种用于防火门的石墨烯掺杂保温防火材料的制备方法，巯基化石墨烯的巯基(‑SH)与马来酸二丁基锡的烯烃部分进行加成反应；这种反应是通过巯基与碳碳双键的直接加成，形成更加稳定的硫醚键；这样的结构改变增强了石墨烯与其他组分之间的相互作用，提高了防火材料的热稳定性和阻燃性能；1，1`‑二(二甲基硅基)铁中的硅氢键(Si‑H)与马来酸二丁基锡的烯烃部分发生加成反应；这个反应通过硅原子与碳碳双键的加成，形成二茂铁的硅碳键(Si‑C)，进一步增强了材料的结构稳定性和耐高温性能；本发明制备的用于防火门的石墨烯掺杂保温防火材料，达到A1级防火建材标准。
