Anticorrosive flame-retardant treatment process for glass fiber reinforced plastic grid

Abstract

The invention discloses an anticorrosive flame-retardant treatment process for a glass fiber reinforced plastic grid. The anticorrosive flame-retardant treatment process comprises the following steps: mixing unsaturated resin, a curing agent, a plasticizer, a diluent and a modifier to prepare resin mixed liquor, injecting the resin mixed liquor into a liquor storage tank, transmitting glass fiber filaments into the unsaturated resin storage tank by a guide mechanism for being sufficiently soaked, heating and curing the soaked glass fiber filaments, and taking out the glass fiber filaments after de-molding the glass fiber filaments; placing a glass fiber reinforced plastic semi-finished product on a workbench, then coating a layer of unsaturated polyester resin on the surface of the glass fiber reinforced plastic semi-finished product, immediately coating a layer of melamine resin cover on the unsaturated polyester resin and then coating a silicon dioxide wear-resisting layer on the melamine resin cover; placing the glass fiber reinforced plastic semi-finished product, upper and lower surfaces of which are adhered, into a hot press to carry out hot-pressing; and cutting and trimming glass fiber reinforced plastics subjected to the hot-pressing, and checking and warehousing a finished product. The anticorrosive flame-retardant treatment process is high in production efficiency, fireproof and flame-retardant, wear-resisting and efficient, advanced in production process and capable of resisting ageing and prolonging the service life.

Description

technical field [0001] The invention relates to the field of composite material manufacturing, in particular to an anti-corrosion and flame-retardant treatment process for FRP grids. Background technique [0002] Glass fiber is an inorganic non-metallic material with excellent performance. There are many kinds. The advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but the disadvantages are brittleness and poor wear resistance. It is made of glass balls or waste glass through high-temperature melting, wire drawing, winding, weaving and other processes. The diameter of its single filament is several microns to more than 20 microns, which is equivalent to a hair. 1 / 20-1 / 5 of that, each bundle of fiber precursors consists of hundreds or even thousands of monofilaments. The glass fiber is often used as reinforcing material of composite material, electrical insulation and heat insulation materials, substrate and other ...
