Abstract

The invention discloses a glass fiber reinforced plastic curing agent composition and a glass fiber reinforced plastic composite material prepared by the same as well as a cable trough. The glass fiber reinforced plastic curing agent composition is formed by the following components in parts by weight: 50-60 parts of unsaturated polyester resin, 15-20 parts of aluminum hydroxide, 1-2 parts of zinc stearate, 0.2-0.5 part of de-molding agent, 0.5-1 part of benzoyl peroxide, 0.5-1 part of benzoyl peroxide tert-butyl ester, 0.1-0.2 part of antioxidant, 0.1-0.2 part of ultraviolet absorbent, and 0.1-0.2 part of antistatic agent. A glass fiber reinforced plastic material is prepared by an extruding and molding process. The glass fiber reinforced plastic material prepared by the curing agent composition disclosed by the invention is low in production cost, has light weight and high strength, and has good weather resistance even under an extreme hygrothermal environment.

Description

technical field [0001] The invention relates to the field of FRP production, in particular to a FRP curing agent composition, a FRP material and a cable trough made from it. Background technique [0002] With the progress of society and the development of science and technology, the role and value of information for human beings are becoming more and more important, and the carrier of information transmission - the safety protection materials of cables, are also increasingly valued by people. The commonly used cable protection facility in the prior art is the cable trough, and its main steel material and magnesite composite material have certain defects, such as easy to rust or poor durability. Therefore, someone proposed to replace steel and magnesite composite materials with glass fiber reinforced plastic materials to overcome the defects of heavy and easy to rust steel and low strength and poor durability of magnesite composite materials, and achieved good results. [00...
