Abstract

The invention discloses an anti-impact polyethylene glycol terephthalate composite material and a preparation method thereof. The composite material is prepared by the following raw materials by weight: 45% to 60% of polyester (PET), 10% to 20% of HIPS, 15% to 25% of glass fiber, 0.1% to 0.5% of antioxygen, 5% to 12% of fire retardant, 0.1% to 0.3% of lubricant and 2% to 10% of compatilizer. The self-prepared compatilizer is added into the polyethylene glycol terephthalate composite material, and rigidity and toughness can be maintained by changing proportions of the components. The material is good in anti-impact performance and low in material cost.

Description

technical field [0001] The invention relates to an impact-resistant polyethylene terephthalate composite material and a preparation method thereof, which can be used in industries such as home appliances and automobiles, and belongs to the technical field of polymer materials. Background technique [0002] Polyethylene terephthalate (PET) is currently the most important polyester, commonly known as polyester resin. PET mainly has the following characteristics: good resistance to organic solvents, weather resistance and dimensional stability. However, PET also has some inherent defects, such as slow crystallization rate, difficult molding process, long production cycle, poor impact performance and so on. Therefore, its comprehensive performance can be significantly improved by filling and strengthening modification. [0003] Modified PET can be widely used in electronic appliances, automobiles and machinery industries. At present, most of the research is to add ABS, PC, PP,...
