Problems solved by technology

[0005] At the same time, in view of the improvement of customers' requirements for the flame retardant performance of current materials at this stage, the development and application prospects of flame retardant ABS materials are also relatively broad. It is easy to react with silver ion antibacterial agents during the process, thereby reducing the antibacterial efficiency of the material
Therefore, so far, there are few reports on the antibacterial research of flame retardant ABS materials.

Abstract

The invention provides a high antibacterial flame-retardant acrylonitrile-butadiene-styrene (ABS) material and a preparation method thereof. The high antibacterial flame-retardant ABS material is prepared from ABS resin, a flexibilizer, a brominated flame retardant, an auxiliary fire retardant, polytetrafluoroethylene, a heat stabilizer, an antioxidant, a lubricating agent, glycerol monostearate and a zinc ion antibacterial agent in parts by weight. By adopting the high antibacterial flame-retardant ABS material, the zinc ion antibacterial agent, the brominated flame retardant and the auxiliary fire retardant are adopted; meanwhile, an efficient dispersant glycerol monostearate is adopted to pre-disperse the antibacterial agent; the antibacterial material can be evenly dispersed in the composition; birdnesting of the antibacterial agent is prevented; meanwhile, gathering of the antibacterial agent at the surface of the flame-retardant ABS material is facilitated by the lubricating effect of the dispersant; the antibacterial effect of the material is greatly improved; the antibacterial effect of the antibacterial agent is improved; the antibacterial property, the fire resistance and excellent mechanical property of the ABS material are improved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a high antibacterial and flame-retardant ABS material and a preparation method thereof. [0002] Background technique [0003] Acrylonitrile-butadiene-styrene copolymer (referred to as ABS resin) is one of the five major synthetic resins, which combines polybutadiene (PB), polyacrylonitrile (PAN), polystyrene (PS) The performance is organically unified, and it has excellent mechanical properties of toughness, hardness, and rigid phase balance; and its impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties are excellent; it is also easy to process and produce Dimensional stability, good surface gloss and other characteristics, so ABS resin is widely used in refrigerators, air conditioners, washing machines and other daily necessities. [0004] At this stage, with the progress of society and the improvem...
