Problems solved by technology

This is because plastics are prone to mold due to migration of internal additives or external pollution, which affects the use of products.
In addition, in order to improve its impact resistance, acrylonitrile-butadiene-styrene copolymers generally add toughening agents, and the small molecular substances and monomers contained in commonly used toughening agents are the source of nutrition for molds, which promote the growth of molds. , increased consumption of antimicrobial agents in antifungal materials
[0004] At present, this goal is generally achieved by adding antibacterial agents, but natural antibacterial agents are highly safe but poor in heat resistance and easy to carbonize and decompose; organic antibacterial agents are fast and efficient in sterilization, but have the disadvantage of poor long-term effect; inorganic antibacterial agents have long-term sterilization Good, but the antibacterial effect is slow, and silver and copper antibacterial agents have the problem of easy discoloration

Abstract

The invention discloses an impact-resistant reinforced mildew-proof acrylonitrile-butadiene-styrene copolymer material and a preparation method thereof. The material is prepared from an acrylonitrile-butadiene-styrene copolymer, polymethyl methacrylate, a mildew preventive and an auxiliary agent. The acrylonitrile-butadiene-styrene copolymer material is modified by adding the compounded mildew preventive and the auxiliary agent, so that the prepared acrylonitrile-butadiene-styrene copolymer material not only has an efficient antibacterial effect and good long-term mildew resistance, but also has high material strength and good impact resistance.

Description

technical field [0001] The invention belongs to the technical field of macromolecules, and in particular relates to an anti-impact reinforced anti-mildew acrylonitrile-butadiene-styrene copolymer material and a preparation method thereof. Background technique [0002] Acrylonitrile-butadiene-styrene copolymer, English name: Acrylonitrile butadiene Styrenecopolymers, ABS for short. ABS is a thermoplastic polymer material with high strength, good toughness and easy processing. ABS resin is a terpolymer of acrylonitrile, 1,3-butadiene and styrene. It can perform normally in the environment of -25°C ~ 60°C, and has good formability. The processed products have a smooth surface and are easy to dye and electroplate. And it can be mixed with various resins to form a blend. It is now mainly used in alloys, plastics, and ABS grades. [0003] With the continuous development of its applications, people have put forward higher and more specific requirements for acrylonitrile-butadie...
