Abstract

The invention discloses a polyester fireproof plate material, which is prepared from the following raw materials in parts by weight: 10 to 13 parts of zinc hydroxystannate, 10 to 15 parts of alkalinediatomite powder, 7 to 8 parts of octyl epoxy stearate, 10 to 14 parts of allyl triphenyl phosphine bromide, 0.01 to 0.012 part of an initiator, 180 to 220 parts of methyl methacrylate, 5 to 7 parts of ammonium persulfate, 30 to 40 parts of ethyl orthosilicate, 0.7 to 1 part of sp-80 and 7 to 12 parts of chlorinated paraffin. According to the invention, the introduced silica sol not only can effectively improve the mechanical properties of the finished plate, but also has a good synergistic antibacterial effect when being blended with the quaternary phosphonium salt, so that the comprehensivequality of the finished material is improved.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a polyester fireproof board material and a preparation method thereof. Background technique [0002] Polymethyl methacrylate, polymers obtained by polymerization of acrylic acid and its esters are collectively referred to as acrylic resins, and the corresponding plastics are collectively referred to as polyacrylic plastics, among which polymethacrylate methyl is the most widely used, polymethylmethacrylate Methyl acrylate resin is a non-toxic and environmentally friendly material, which can be used to produce tableware, sanitary ware, etc. It has good chemical stability and weather resistance. Polymethyl methacrylate resin is not easy to produce sharp fragments when it is broken. The United States, Japan Countries and regions such as China have made mandatory regulations in the law that polymethyl methacrylate resin must be used for glass in primary and secondary schools and ...
