Problems solved by technology

Its modified material has excellent mechanical properties in a wide temperature range, and its long-term use temperature can reach 140 ° C. It has excellent electrical insulation. Even at high temperature and high frequency, its electrical and mechanical properties are still good, and its creep resistance resistance, fatigue resistance, friction resistance, excellent dimensional stability, and high heat distortion temperature, but its corona resistance is poor, crystallization speed is slow, and low temperature resistance is poor
[0004] A lot of research has been carried out on the melt blending modification of ABS and PET resins. However, the compatibility between the two is not very good, resulting in low mechanical properties, especially impact resistance, and the transparency of the materials modified by the two. Poor, thus affecting its application

Abstract

The invention discloses an acrylonitrile butadiene styrene / polyethylene terephthalate (ABS / PET) composite and a preparation method of the ABS / PET composite. The ABS / PET composite comprises the following formula components, by weight, 100 portions of ABS, 10-40 portions of PET, 5-35 portions of polyethylene terephthalate glycol (PETG), 1-8 portions of permeability improving agents, 0.5-3 portions of antioxidant and 0.5-3 portions of processing agents. According to the ABS / PET composite, ABS and PET serve as matrix components, and in the process of melt extrusion, the components are subjected to synergistic effect. Thus, the ABS / PET composite has high transparency and excellent processing and mechanical properties, and the anti-shocking performance is particularly excellent. Besides, the ABS / PET composite is easy to color and can maintain the original transparent effect of the materials after colored. The composite is relatively strong in chemical corrosion resistance, stable in size, and small in creep deformation. The preparation method of the ABS / PET composite is simple in technology, the conditions are easy to control, the cost is low, and the requirements for equipment is low, and the preparation method of the ABS / PET composite is suitable for industrial production.
