Embodiment 1

[0019] Example 1: An anti-corrosion and flame-retardant treatment process for FRP gratings, the steps are as follows: mix unsaturated resin, curing agent, plasticizer, diluent, and modifier to form a resin mixture and inject it into the liquid storage tank. The mass ratio of the above unsaturated resin is 100:1.75-2:2-2.5:0.5-1:0.5-1, and then the glass fiber filaments are transported by the guide mechanism to the unsaturated resin storage tank for full impregnation; The glass fiber filaments are introduced into the mold and heated and solidified, and taken out after demoulding; place the semi-finished FRP product on the workbench, coat a layer of unsaturated polyester resin on its surface, and immediately cover a layer of melamine resin skin on the unsaturated polyester On the resin, put a layer of silicon dioxide wear-resistant layer on the melamine resin skin; turn the FRP semi-finished product 180 degrees, apply a layer of unsaturated polyester resin on the other side, and ...

Embodiment 2

[0020] Example 2: Mix unsaturated resin, curing agent, plasticizer, diluent, and modifier to form a resin mixture and inject it into the reservoir. The unsaturated resin has a mass ratio of 100:1.75:2: 0.5:0.5, and then transfer the glass fiber filaments from the guide mechanism to the unsaturated resin reservoir for full impregnation.

Embodiment 3

[0021] Example 3: Mix unsaturated resin, curing agent, plasticizer, diluent, and modifier to form a resin mixture and inject it into the reservoir. The unsaturated resin has a mass ratio of 100:2:2.5: 1:1, and then the glass fiber filaments are transported by the guiding mechanism to the unsaturated resin reservoir for full impregnation, the glass fiber filaments are introduced into the mold to be heated and cured by electric heating, and the release agent is added before demoulding.

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 ...
