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 anti-aging glass fiber reinforced plastic material. The anti-aging glass fiber reinforced plastic material 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 a curing agent, 1-3 parts of an accelerant, 80-120 parts of glass fibers, 10-40 parts of an illite functional powder material, 1-3 parts of a coupling agent I, 1-2 parts of zinc oxide and 5-6 parts of graphene. The preparation method comprises the following steps: pickling illite powder, washing with water to be neutral, drying, and modifying with a coupling agent II to obtain the illite functional powder material. The illite functional powder material is added and compounded with other raw materials, so that the crosslinking degree between macromolecular chains can be increased; the anti-aging glass fiber reinforced plastic material is particularly suitable for marine environments such as ships, and the salt fog resistance, the aging resistance and the strength of the anti-aging glass fiber reinforced plastic material are remarkably improved compared with those of a common glass fiber reinforced plastic material.

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...
