Abstract

The invention discloses an acrylic plate with excellent bending performance and a preparation method thereof, relates to the technical field of acrylic plates, and aims to solve the problems of brittleness, low impact strength and poorer bending performance of an existing acrylic plate. The acrylic plate comprises a polymerization monomer, an initiator, a stabilizer, a plasticizer, reinforcing fibers and a flame retardant, the polymerization monomer is formed by quaternary copolymerization of methyl methacrylate, acrylic acid, butyl acrylate and diallyl adipate, and the reinforcing fibers comprise unidirectional borosilicate glass fibers and short carbon fibers. The initiator is one or a combination of azobisisovaleronitrile, azobisisobutyronitrile and benzoyl peroxide, the stabilizer is cuprous chloride and methyltin, the plasticizer is one or a combination of dibutyl phthalate, phthalate, sebacate, chlorinated paraffin and camphor, the flame retardant is one or a combination of is bromo-phosphate, and the coupling agent is one or a combination of bromophosphate, dimethyl methylphosphonate and diethylhexyl tetrabromo phthalate.

Description

technical field [0001] The invention relates to the technical field of acrylic plates, in particular to an acrylic plate with excellent bending performance and a preparation method thereof. Background technique [0002] Acrylic, also known as specially treated plexiglass, is a replacement product of plexiglass. The board made of acrylic has the characteristics of good light transmission, pure color, rich color, beautiful and flat, long service life, and does not affect use. In addition, acrylic sheets can be perfectly combined with aluminum-plastic sheet profiles, advanced screen printing, etc., and it is a chemical material. The chemical name "PMMA" belongs to polyacrylate. The acrylic sheet has crystal-like transparency, and the light transmittance is over 92%. The acrylic sheet colored with dye has a good color development effect. In addition, the acrylic sheet has excellent Weather resistance, high surface hardness and surface gloss, and good high temperature resistance...
