Abstract

The invention discloses an antibacterial flame-retardant ABS material and a preparation method thereof. The antibacterial flame-retardant ABS material is prepared from ABS resin, a flame-retarding agent, a coordinative flame-retarding agent, an auxiliary flame-retarding agent, a thermal stabilizer, an antibacterial master batch, a compatilizer, an antioxidant and a lubricating agent in parts by weight, wherein the antibacterial master batch is prepared from ABS and at least one of a silver ion type antibacterial agent, zinc oxide and copper oxide by a mass ratio of 10 to 1. According to the ABS material disclosed by the invention, the silver ion type antibacterial agent or the zinc oxide or the copper oxide and the ABS are used for preparing the antibacterial master batch by the mass ratio of 10 to 1, so that the silver ion type antibacterial agent or the zinc oxide or the copper oxide is effectively uniformly dispersed in the ABS resin in order to improve the antibacterial efficiency and achieve a better antibacterial effect than an antibacterial agent which is used independently; and color changes of antibacterial ABS plastic can be effectively prevented, and the antibacterial properties of the antibacterial ABS plastic can be improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an antibacterial and flame-retardant ABS material and a preparation method thereof. Background technique [0002] Acrylonitrile-butadiene-styrene resin (abbreviated as ABS) is an important general-purpose synthetic resin. As a joint between general-purpose synthetic resin and engineering plastics, it has special importance. ABS resin is composed of more than 50% styrene and variable amounts of butadiene and acrylonitrile. Among them, styrene provides hardness and ease of processing, acrylonitrile provides chemical resistance and thermal stability, and butadiene provides toughness and impact strength. Therefore, ABS resin has the characteristics of high impact strength, good heat resistance and low temperature resistance, and is easy to process. It is widely used in the fields of electronic appliances, auto parts, stationery, daily necessities and industrial parts. ...
