Problems solved by technology

Since this method is carried out at room temperature and is obtained by conventional methods, the antibacterial properties of the prepared antibacterial plastic products cannot be fully exerted. At the same time, with the release of the antibacterial agent, the antibacterial activity is getting smaller and smaller, and the antibacterial agent is easily inactivated. , fail to achieve the purpose of antibacterial

Abstract

The invention discloses an antibacterial ABS (acrylonitrile butadiene styrene) plastic, which is prepared from the following raw materials in percentage by weight: 94.5 to 98.5 percent of ABS plastic masterbatch, 1.0 to 5.0 percent of acrylonitrile, 0.001 to 0.05 percent of nano-silver, 0.002 to 0.05 percent of dispersant, and 0.1 to 0.5 percent of antioxidant. The invention also discloses a preparation method of the antibacterial ABS plastic, which comprises the following steps of: uniformly mixing the acrylonitrile, the nano-silver and the dispersant to obtain a mixed auxiliary material; heating, stirring and mixing the mixed auxiliary material, the ABS plastic masterbatch, the antioxidant and an organic solvent in a stainless steel stirrer to obtain a mixed raw material; and extruding and granulating the mixed raw material to obtain the antibacterial ABS plastic. The preparation method has a simple process; and the prepared antibacterial plastic has strong bacteria resistance, and a lasting antibacterial effect.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an antibacterial ABS plastic and a preparation method thereof. Background technique [0002] At present, plastic products play a very important role in people's daily life and industrial and agricultural production. With the wide popularization and application of plastic products in the field of daily necessities, people frequently come into contact with and use plastic products, thus the requirements for plastic products are getting higher and higher. People often add some nanoscale silver, copper, zinc and other ions with bactericidal and antibacterial functions to plastic products to endow plastics with antibacterial functions. At present, antibacterial plastics have received widespread attention. [0003] The surface gloss of acrylonitrile-butadiene-styrene copolymer (ABS) material is good, and the casing of most electrical appliances is prepared by it...
