Description

technical field [0001] The invention relates to the technical field of resins, in particular to a heat-resistant and aging-resistant high tensile strength ABS resin and a preparation process thereof. Background technique [0002] Polycarbonates are resins that can maintain good mechanical properties at high temperatures, but their relatively high price limits their applications. Conventional ABS resin (acrylonitrile-butadiene-styrene terpolymer) has many advantages such as good impact resistance, processability, dimensional stability, wear resistance and chemical corrosion resistance, and its service temperature range can be It varies between -40 and 100°C, so ABS resin has been widely used in many fields such as automobiles, home appliances, daily necessities, sporting goods, and office supplies in recent years. However, conventional ABS resin is limited by its own structure, and it is difficult to maintain its good rigidity and hardness when the temperature is higher than...
