Problems solved by technology

The resin based on PCT (1,4-cyclohexanedimethylene terephthalate) has good temperature resistance, but the material performance is insufficient and the cost is high
[0005] Existing polyester resin-based composite materials use a large amount of glass fiber or talcum powder as the reinforcing material system, but with the thinning and miniaturization of applied products, the large amount of glass fiber or talcum powder leads to fluidity during processing. Poor, difficult to process into thin-walled and miniaturized devices, and the enhancement effect is not enough, it can no longer fully meet the needs of the market

Abstract

The invention discloses a high anti-environmental aging and high temperature resistant polyester resin matrix composite material. The composite material is prepared by mixing of the following raw materials by weight percentage: 30-80% of thermoplastic resin, 0.5-15% of modified attapulgite powder, 5-30% of titanium dioxide, 0.1-0.5% of an antioxidant, 0.2-0.5% of a mould release agent, 3-10% of glass fiber, and 5-20% of mineral powder. The composite material provided by the invention has the advantages of high temperature resistance, good aging resistance, high structural strength, high dimensional stability under long-term high temperature use condition, high anti-yellowing performance, and high flow performance under processing condition, and is suitable for application in thin walled parts.

Description

Technical field [0001] The invention relates to a polyester resin-based composite material, in particular to a polyester resin-based composite material with high environmental aging resistance and high temperature resistance. Background technique [0002] Polyethylene terephthalate (PET) is a crystalline saturated polyester resin, generally a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface. It has excellent physical and mechanical properties in a wide temperature range. The long-term use temperature can reach 120℃, and the short-term use temperature can reach 150℃. It can withstand low temperatures of -70℃ and has little effect on its mechanical properties at high and low temperatures. ; Excellent electrical insulation, creep resistance, fatigue resistance, friction resistance, and dimensional stability; stable chemical resistance, low gas and water vapor permeability, and good barriers to gas, water, oil and Odor performance; high transpa...
