Abstract

The invention discloses a weatherproof and antibacterial polycarbonate engineering plastic and a preparation method thereof. The engineering plastic is prepared from the following raw materials in part by weight: polycarbonate, weatherproof resin ASA, an antibacterialagent, a flexibilizer, a compatilizer, a dispersing agent, an antioxygen and other aids. The preparation method comprises the following steps: a, respectively performing force air drying on the polycarbonate and the weatherproof resin ASA; b, weighing the antibacterialagent and the dispersing agent, and mixing the two uniformly; c, weighing the flexibilizer, the compatilizer, the antioxygen and other aids, and putting into a super mixer for dry mixing, together with raw materials in step a and step b; and d, putting the mixedmaterials in the step c into a twin-screw extruder, and performing melt extrusion for granulation. The weatherproof and antibacterial polycarbonate engineering plastic has the advantages of ageing resistance, yellowing resistance, good weatherability, and durable antibacterial function.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a polycarbonate engineering plastic and a preparation method thereof. It can be widely used in automotive industry, electronic and electrical industry, machinery industry and other fields, such as automotive exterior parts, outdoor parts of home appliances, communication products, etc. Background technique [0002] Polycarbonate (PC) is a type of polymer containing carbonate in the molecular chain. It has particularly good impact strength, thermal stability, and gloss. It is one of the five general-purpose engineering plastics, and its output and consumption are second only to Nylon engineering plastics ranked second. Modified PC has excellent comprehensive performance, such as PC / ABS (polycarbonate / acrylonitrile-styrene-butadiene copolymer) composite material is the main variety of modified PC, and it is also an important engineering plastic composite material.
