Problems solved by technology

[0002] FRP is a composite material, which is composed of two or more materials to form another material that can meet people's requirements. It is widely used in engineering construction, automobiles and mechanical parts. However, the current FRP material After being exposed to light, the aging speed is accelerated, and the strength of the surface itself is low, which affects the use in actual life

Abstract

The invention relates to the technical field of glass fiber reinforced plastic materials, in particular to a black anti-aging glass fiber reinforced plastic composite material. The material comprisesthe following components by weight: 50-60 parts of polyester resin, 20-30 parts of glass fiber, 10-23 parts of filler, 5-8 parts of a light stabilizer, 2-6 parts of an accelerant, 5-15 parts of a curing agent and 20-35 parts of a black color paste. The filler comprises 3-9 parts of calcium powder, 5-10 parts of glass beads and 3-4 parts of aluminum hydroxide; and the accelerant is any one of cyclohexanone peroxide, methyl ethyl ketone peroxide or dibenzoyl peroxide. The invention provides the black anti-aging glass fiber reinforced plastic composite material, under the condition of long-time illumination, the aging speed can be slowed down, the service life is prolonged, and meanwhile, through raw material collocation, the surface hardness is also greatly improved.

Description

technical field [0001] The invention relates to the technical field of FRP materials, in particular to a black aging-resistant FRP composite material. Background technique [0002] FRP is a composite material, which is composed of two or more materials to form another material that can meet people's requirements. It is widely used in engineering construction, automobiles and mechanical parts. However, the current FRP material After being exposed to light, the aging speed is accelerated, and the strength of the surface itself is low, which affects the use in actual life. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a black anti-aging FRP composite material for the above-mentioned technical deficiencies, which can slow down the aging speed and improve the service life under long-term light conditions. Hardness has also been greatly improved. [0004] In order to solve the above-mentioned technical problems, th...
