Glass reinforced plastic forming method and glass reinforced plastic forming system

Abstract

The invention discloses a glass reinforced plastic forming method and a glass reinforced plastic forming system. The method comprises the following steps of: respectively pressurizing a phenolic resin feed liquid, a solidified agent and a glass fiber so as to spurt in a shape of fans and converge through three nozzlesof a spraying gun, wherein the fan-shaped injection surfaces of the solidified agent and the glass fiber are respectively positioned on the two sides of the injection surface formed by phenolic resin so as to spurt; injecting the solidifying feed liquid after converging under the propulsion of the injection pressure of the bakelite feed liquid in a fan shape to the target injection surface, and curing and forming the solidifying feed liquid on the target injection surface. The glass reinforced plastic forming method and the glass reinforced plastic forming system provided by the invention have the advantages that a purpose that the spraying gun is used for injecting so as to uniformly mix the phenolic resin, the solidified agent and the glass fiber is achieved through regulating the viscosity of the bakelite feed liquid, the bakelite forming efficiency is improved, the manufacture environment of employees is improved, and a gummosis condition meets a field injecting liner manufacturing process.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced plastic molding, in particular to a glass fiber reinforced plastic molding method and a system thereof by injection molding of phenolic resin. Background technique [0002] Phenolic resin has excellent corrosion resistance and temperature resistance, its performance far exceeds that of unsaturated resin, and also exceeds vinyl resin in some aspects, and its price is low, but it is restricted due to its difficult operation and slow curing. Therefore, the application in FRP is seldom used, especially in the large tank market. Due to the characteristics of phenolic resin, the curing speed of phenolic resin is much slower than that of unsaturated resin, and it needs to be heated to cure, which relatively prolongs the production cycle of phenolic FRP products. There is no successful example of using a spray gun in China, and it is generally achieved by hand painting. [0003] At presen...

AI Technical Summary

Problems solved by technology

[0004] One is the viscosity of phenolic resin. The general viscosity of phenolic resin is above 800MPa s / 25°C. Due to the high viscosity of phenolic resin, it is difficult to spray it through a spray gun.
