Problems solved by technology

[0003] The synthesis of traditional phenolic resin is generally prepared by phenol and liquid formaldehyde (the mass fraction of liquid formaldehyde is 37-40%). In the production process, not only the energy consumption is high, the labor efficiency is low, but also a large amount of phenolic resin will be produced during the dehydration or drying process. Waste water, according to statistics, every ton of thermoplastic phenolic resin produces 500-600 kg of waste water, and every ton of thermosetting phenolic resin produces 600-800 kg of waste water. The manufacturer adopts various methods to treat phenolic waste water, and has received certain results , but still cannot fundamentally solve the problem

Abstract

The invention provides glass-fiber reinforced molded plastic of heat-resistant environment-friendly phenolic resin, and relates to the technical field of synthetic resin material processing and manufacture. The plastic is characterized by comprising environment-friendly phenolic resin, alkali-free glass fiber cut silk, coupling agent KH-550, internal releasing agent, pigment, silicon dioxide, industrial alcohol, graphite and siliceous lime. The glass-fiber reinforced molded plastic has the advantages of reasonable method, clear proportion, high tensile strength, good bending strength and low heat distortion temperature.

Description

Technical field: [0001] The invention relates to the technical field of material processing and production of synthetic resins, in particular to a glass fiber-reinforced molding compound of heat-resistant and environmentally friendly phenolic resin. Background technique: [0002] As one of the three thermosetting resins, phenolic resin has a development history of more than 100 years. Its remarkable features are low price, heat resistance, ablation resistance, flame retardancy, and less smoke when burning. With the development of electronics, machinery, transportation, etc. With the rapid development of transportation and national defense industry, phenolic resin and its composite materials have also been developed rapidly, but the weakness of ordinary phenolic resin is that hydroxyl and methylene are easily oxidized, and phenolic hydroxyl generally does not participate in chemical reactions in resin synthesis. There are many hydroxyl groups, and the phenolic hydroxyl group ...
