Problems solved by technology

Although this patent solution can embody the technical effect of the last paragraph on page 2 to the 12th line on page 3 of the specification, and has significant achievements compared with Japanese patent No. 57-200440, it lacks mechanical strength, slow molding speed, and unit It is a shortcoming that the molding efficiency of the product within a short time is low and the cost is high. Therefore, it is not necessary to plan the aforementioned phenolic molding compound with ideal antistatic effect, good mechanical strength, outstanding wear resistance and processability. has the meaning of reference

Abstract

The invention discloses antistatic phenolic moulding plastic, and belongs to the technical field of thermosetting plastics. The antistatic phenolic moulding plastic is prepared from the following raw materials in parts by weight: 20.0-45.0 parts of phenolic resin, 4.0-8.0 parts of curing agent, 0.2-2.0 parts of curing accelerator, 1.0-3.0 parts of lubricating agent, 5.0-30.0 parts of glass fiber, 10.0-20.0 parts of lignocellulose, 1.0-10.0 parts of conductive carbon black, 15.0-30.0 parts of nano inorganic filler, 0.5-2.0 parts of coupling agent and 5.0-20.0 parts of graphite. Through reasonable dosages of the nano inorganic filler, the coupling agent, the graphite and the conductive carbon black, the antistatic phenolic moulding plastic can realize ideal improvement on the antistatic effect, so as to meet antistatic requirements of packing materials for mineral electric equipment products and flammable and combustible materials; due to reasonable dosage of the glass fiber, the antistatic phenolic moulding plastic has obviously improved mechanical strength and shows wear resistance; the antistatic phenolic moulding plastic is cheap in selected materials, and can meet industrial high-efficiency amplified production requirements.

Description

technical field [0001] The invention belongs to the technical field of thermosetting plastics, and in particular relates to an antistatic phenolic molding compound. Background technique [0002] Phenolic molding compound is widely used due to its advantages of simple production process, easy availability of raw materials and low price, and excellent comprehensive performance of products obtained by injection molding. It is based on phenolic resin, supplemented by fillers and curing agents The additives are made by mixing and masticating. [0003] Although composite materials made of glass fiber reinforced phenolic resin base have good insulation properties, most of them are combustible materials, so when encountering situations such as friction, extrusion and impact, the surface of the product will generate static electricity due to charge accumulation , Electrostatic discharge can lead to production failures, fires and even explosions, resulting in economic losses and casu...
