Preparation method of environment-friendly antibacterial plastic

Abstract

The invention discloses a preparation method of environment-friendly antibacterial plastic. The preparation method comprises the following steps: stirring and mixing ABS, a silane coupling agent, a toughening agent, a dispersing agent, a foaming agent and an environment-friendly antibacterial agent together in a high-speed mixer or an internal mixer, after the materials are uniformly mixed, addinga mixture into a twin-screw extruder, wherein processing temperatures of the twin-screw extruder are as follows: temperature of a first area is 175 DEG C, temperature of a second area is 185 DEG C, temperature of a third area is 190 DEG C, temperature of a fourth area is 195 DEG C, temperature of a fifth area is 210 DEG C, temperature of a sixth area is 220 DEG C, temperature of a seventh area is230 DEG C, temperature of an eighth area is 240 DEG C, and temperature of a ninth area is 245 DEG C, extruding, then cooling and staying, and carrying out air drying and dicing, so that the environment-friendly antibacterial plastic is obtained; and the following raw materials in parts by weight are adopted: 50 parts of ABS, 5 parts of the silane coupling agent, 10 parts of the toughening agent,1 part of the dispersing agent, 2 parts of the foaming agent and 1 part of the environment-friendly antibacterial agent, and the environment-friendly antibacterial agent comprises a mixture of antibacterial masterbatches and titanium dioxide. The environment-friendly antibacterial agent is added, so that the environment-friendly antibacterial property of ABS plastic is greatly improved.

Description

technical field [0001] The invention relates to a preparation method of an environment-friendly antibacterial plastic. Background technique [0002] ABS resin is an important general-purpose synthetic resin, mainly a blend or terpolymer of acrylonitrile, butadiene and styrene. It is a tough and rigid thermoplastic with a wide range of uses. It is often used in the automotive industry. Manufacture of auto parts such as instrument panels, body panels, interior trim panels, steering wheels, etc. The home appliance industry is often used to manufacture such as refrigerators, televisions, vacuum cleaners, etc., and the construction industry commonly used to manufacture such as sanitary appliances, swimming pool linings, pipes And pipe fittings, etc., in addition to the manufacture of helmets, motorcycle baffles, toys, clocks, cosmetic boxes and so on. [0003] Although ABS is widely used, due to the characteristics of the molecular structure and performance of ABS itself, ABS is...
