Problems solved by technology

At present, the pultrusion molding process of PMMA composite materials is divided into two types: one is pre-impregnated fiber pultrusion molding, which needs to complete the fiber resin impregnation separately before pultrusion molding, and the pre-impregnated fiber must be heated before entering the mold. The resin matrix is ​​in a viscous flow state, and then pultruded by a pultrusion device, and the composite material just out of the mold needs to be cooled; the other is direct pultrusion of fibers, which requires additional extrusion equipment on the basis of thermosetting resin composite pultrusion equipment. Out of the machine, the thermop

Abstract

The invention provides a flame-retardant PMMA (polymethyl methacrylate) resin material, a composite material and a preparation method thereof. The flame-retardant PMMA resin material comprises the following components in parts by mass: 100 parts of methyl methacrylate, 0.5-5 parts of a compound initiator, 0-50 parts of inorganic flame-retardant filler, 5-80 parts of a flame retardant and 2-5 parts of a release agent, the compound initiator is a combination of two or more than two of dibenzoyl peroxide, bis (4-tert-butylcyclohexyl) peroxydicarbonate, bis (lauroyl) peroxide, tert-butyl peroxy-2-ethylhexanoate and tert-butyl perbenzoate. According to the resin material, methyl methacrylate serves as a monomer, fibers are impregnated in an impregnation tank, monomer free radical polymerization is initiated in a mold under the action of a compound initiator, the monomer is low in viscosity and good in fluidity, equipment does not need to be transformed, pultrusion is completed directly through a thermosetting resin device, the existing thermoplastic pultrusion process is simplified, and operation is convenient; the composition of the initiator and the flame retardant is further improved, so that the mechanical property and the flame-retardant effect of the composite material are better.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and particularly relates to a flame-retardant PMMA resin material, a composite material and a preparation method thereof. Background technique [0002] The pultrusion process is a process in which reinforcing materials such as glass fiber are impregnated with phenolic resin under the traction of external force, and then preformed and cured by hot mold, and finally a continuous regular cross-section product is formed. It is a process method for continuous production of linear composite products. , has the advantages of low cost and high production efficiency. [0003] Thermosetting refers to a resin that undergoes chemical changes after heating, gradually hardens and forms, and does not soften or dissolve when heated; thermoplastic resins have the properties of softening by heating, hardening by cooling, and no chemical reaction, regardless of heating and cooling. No matter how many t...
