Problems solved by technology

[0003] However, FRP is a fiber-reinforced plastic, which has the common defects of plastics, and is prone to aging phenomena. It is easy to cause performance defects under the action of ultraviolet rays, mechanical stress, wind, sand, rain, snow, media, etc., especially in marine environments, long-term exposure to ultraviolet rays, seawater, etc. The corrosion caused by the influence of ocean, atmosphere and marine organisms has seriously affected the performance and service life of FRP products.

Abstract

The invention provides an aging-resistant FRP material, which is prepared from the following raw materials in parts by weight: 100 parts of unsaturated polyester resin, 2-8 parts of styrene, 1-3 parts of curing agent, 1-3 parts of accelerator, 80-120 parts of glass fiber, 10-40 parts of illite functional powder material, 1-3 parts of coupling agent, 1-2 parts of zinc oxide, 5-6 parts of graphene. The preparation method is to pickle the illite powder, wash it with water until it is neutral, dry it, and use a coupling agent for secondary modification to obtain the illite functional powder material. The addition of illite functional powder material and other raw materials of the present invention can increase the degree of cross-linking between polymer chains, and effectively improve the aging resistance and mechanical strength of the FRP material. The aging-resistant FRP material of the present invention is especially suitable for ships and other marine applications. environment, its salt spray resistance, aging resistance and strength are significantly improved compared with ordinary FRP materials.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and relates to an aging-resistant glass fiber reinforced plastic material and a preparation method thereof. Background technique [0002] FRP, also known as fiber-reinforced plastic, refers to a composite material made of glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix, glass fiber, carbon fiber or boron fiber as reinforcing materials, and made through a composite process. Due to the different types of resin used, it is called polyester FRP, epoxy FRP, and phenolic FRP. The material is light and hard, non-conductive, high mechanical strength, good insulation, less recycling, good thermal performance, and corrosion resistance. The relative density of FRP is between 1.2-2.0, only 1 / 4-1 / 5 of that of carbon steel, but its tensile strength is close to or even higher than that of carbon steel, and its specific strength can be compared with that of high-g...
