High-strength low temperature-resistant glass reinforced plastic and preparation method thereof

Abstract

The invention provides a high-strength low temperature-resistant glass reinforced plastic and a preparation method thereof, and relates to the technical field of glass fiber reinforced plastic processing. The high-strength low temperature-resistant FRP composite material is prepared from, by weight, 14-15 parts of a glass fiber, 12-14 parts of an unsaturated polyester resin, 8-10 parts of acetal resin, 12-14 parts of an epoxy resin, 4-6 parts of a carbon fiber, 2-4 parts of kaolin, 1-3 parts of diatomite, 2-3 parts of dioctyl maleate, 1-2 parts of molybdenum dioxide, 2-3 parts of zinc oxide, 1-3 parts of nanometer titanium dioxide, 2-3 parts of copovidone, 1-3 parts of hexamethylphosphoric triamide, 1-2 parts of diisobutyl phthalate, 2-3 parts of sodium polyacrylate, 1-3 parts of a crosslinking agent, 2-2.4 parts of a lubricant and 1-2 parts of an antioxidant. The preparation method overcomes the deficiencies of the prior art, improves the strength of the glass fiber reinforced plasticmaterial, and can greatly improve the cold resistance, enhance the stability of the product in a low temperature environment, enlarge the application range and increase economic benefits by compounding a plurality of substances.

Description

technical field [0001] The invention relates to the technical field of FRP processing, in particular to a high-strength and low-temperature resistant FRP and a preparation method thereof. Background technique [0002] Fiberglass, also known as GFRP, or fiber reinforced plastic, refers to the use of glass fiber to reinforce unsaturated polyester, epoxy resin and phenolic resin matrix, and glass fiber, carbon fiber or boron fiber as reinforcement materials. Composite material made by composite process. [0003] As a composite material, its formula can be adjusted according to its different scope of use to meet the application in aerospace, railway, decorative construction, home furniture, advertising display and other fields. The main material is resin, and its strength is also strengthened with the addition of glass fiber, but there is still a certain gap in the demand strength of various industries.

Problems solved by technology

[0003] As a composite material, FRP can adjust its formulation according to its range of use, so as to meet the needs of aerospace, railways, decorative buildings, home furniture, advertising display, etc. The main material is resin. With the addition of glass fiber, its strength is also strengthened, but there is still a certain gap in the strength demanded by various industries.

[0004] In order to solve the problem of insufficient strength of FRP, "a high-strength FRP" with the retrieved application number CN201610505694.3 provides a FRP formula in which various metal components are added to strengthen the strength of FRP. However, due to the main base of FRP itself The material is resin, which has the phenomenon of low-temperature embrittlement, which seriously affects the scope of application and service life of FRP. Therefore, research on a high-strength and low-temperature-resistant FRP is a major direction at this stage.
