Abstract

The invention discloses a glass-fiber-reinforced PET / ABS composite material and a preparation method thereof. The glass-fiber-reinforced PET / ABS composite material comprises the following components in percentage by mass: 20%-50% of PET, 20%-50% of ABS, 15%-30% of glass fiber, 3%-8% of a compatibilizer, 0.5%-2% of a lubricant, 0.1%-1% of an antioxidant and 0.1-1% of a light stabilizer. The PET / ABS composite material prepared by the preparation method has the beneficial effects of good compatibility, strong aging resistance, good processing flowability, high notched impact strength, good elongation at break and heat resistance and excellent comprehensive properties, particularly excellent mechanical properties; by adding the glass fiber, the strength of the material is not only further increased and the temperature value of the glow wire of the material is also significantly increased.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a glass fiber reinforced PET / ABS composite material and a preparation method thereof. Background technique [0002] Polyethylene terephthalate (PET) was widely used in the 1960s due to its low price and excellent wear resistance, heat resistance, chemical resistance, electrical insulation, molding dimensional stability and high mechanical strength. S is widely used as an engineering plastic. However, PET has disadvantages such as slow crystallization speed, difficult molding process, high mold temperature, long molding cycle, poor impact strength, and high water absorption, which limit its application. ABS (acrylonitrile-butadiene-styrene copolymer) is currently the plastic with the largest output and the most widely used, and the price is relatively cheap. ABS not only has the mechanical properties of toughness, hardness, and rigid phase balance, but also has good siz...
