Abstract

The invention discloses an ABS modified material with high heat resistance, high gloss and flame retardance and a preparation method thereof. The material comprises ABS, SAN (Styrene Acrylonitrile), a flame retardant, a heat resistant agent, a compatibilizer, an antioxidant and a lubricating agent. The preparation method comprises the steps of: weighing raw materials; sequentially adding the raw materials into a high mixing machine in a material mixing sequence; stirring and mixing for at least 2 minutes; putting the mixed raw materials into a double-screw extruder for extruding and granulating, wherein the screw rotating speed is 200 to 450 revolutions/minute, the screw temperature is 180 DEG C to 220 DEG C, the residence time is 1 to 2 minutes and the melt pressure is 10 to 20MPa; extruding to obtain particles; and drying the particles at 60 DEG C to 90 DEG C for 2 to 4 hours. The invention provides the ABS modified material which achieves high heat resistance, flame retardance and high gloss.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to an ABS modified material, in particular to a high heat-resistant, high-gloss, flame-retardant ABS modified material and a preparation method thereof. Background technique [0002] Acrylonitrile-butadiene-styrene copolymer (ABS) is widely used in machinery due to its good rigidity, hardness, high toughness and processing fluidity, low cost and light weight. , household appliances, daily appliances and other industries. However, since the ABS material contains butadiene rubber, its oxygen index is about 18%, and it is a flammable product. If it is to be made into a home appliance, it needs to be modified for flame retardancy. On the other hand, the automotive industry and the home appliance industry also have an increased demand for ABS materials, such as automotive dashboards, grilles, electric water heater components, heating appliance shells (hair dryers, etc.), etc. ar...
