High-strength fireproof mortar and preparation process thereof
The invention relates to the field of mortar, in particular to high-strength fireproof mortar and a preparation process thereof.The high-strength fireproof mortar is prepared by taking aluminum hydroxide as a flame retardant, modifying the aluminum hydroxide, firstly using (3-mercaptopropyl) trimethoxysilane to sulfhydrylate the surface of the aluminum hydroxide, and then using mercapto-double bond light click to prepare the high-strength fireproof mortar. Introducing a double-bond-containing flame-retardant monomer and vinyl branched polysiloxane to the surface of the flame-retardant resin; the flame-retardant monomer containing double bonds is a flame-retardant monomer prepared by modifying a small molecular flame retardant adenosine monophosphate with glycidyl methacrylate; the vinyl branched polysiloxane is hyperbranched polysiloxane which is synthesized by dipropylene glycol and vinyltriethoxysilane and contains a large number of Si-O bonds and double bonds; the organic silicon modified polycarboxylic acid water reducing agent with strong hydrophilicity, high reaction activity and high water reducing effect is prepared by grafting vinyl branched polysiloxane with strong reaction activity and acrylic acid with strong hydrophilicity by taking an efficient polycarboxylic acid water reducing agent raw material allyl polyoxyethylene ether as a main chain.
