Problems solved by technology

[0005] Ordinary HIPS itself is extremely flammable and releases a large amount of toxic gas, so it is difficult to meet the heat resistance requirements of the electronic and electrical industry
Usually, HIPS meets this requirement by adding a large amount of flame retardants for extrusion modification. Most of the current flame retardants are powders, and the processing site environment is harsh. At the same time, more powder content makes higher requirements for processing equipment. Satisfy the stable flame retardant performance of the final material, and this processing method is only suitable for plastic modification plants, and cannot be applied to end injection molding customers
[0006] At present, HIP plastics with good antibacterial properties and good flame retardant properties are still rare

Abstract

The invention discloses antibacterial HIPS (High Impact Polystyrene) plastic and discloses a preparation method of the antibacterial HIPS plastic. The antibacterial HIPS plastic is prepared from the following raw materials in parts by weight: 45 to 65 parts of HIPS resin, 0.1 to 2 parts of a silane coupling agent, 0.4 to 1.0 part of an antioxidant, 0.3 to 1.2 parts of an antibacterial agent, 12 to18 parts of a flame retardant and 1 to 5 parts of filler. The antibacterial agent is nano-silver and / or melaleuca alternifolia oil. The antibacterial HIPS plastic prepared by the preparation method can be processed and injected into various automobile functional parts, electronic appliance parts and the like. After the antibacterial HIPS plastic disclosed by the invention is used for a long period, the antibacterial HIPS plastic still has relatively strong bacterium inhibition, bacterium killing and mildew-prevention effects.

Description

technical field [0001] The invention relates to an antibacterial plastic, in particular to an antibacterial HIPS plastic and a preparation method thereof. Background technique [0002] The automobile industry has become one of the important pillar industries of my country's national economy. With the development of the economy, due to the comprehensive consideration of energy, environment, economy, and benefits, the high-speed and light-weight transportation tools such as automobiles and railways The increasingly high level of quantification has prompted a substantial increase in the use of plastics in automotive and other industrial fields, especially plastic alloys with high performance and low prices will receive increasing attention. [0003] High-impact polystyrene (HIPS) is one of the five most commonly used general-purpose plastics in industrial production. It has the advantages of low specific gravity, easy molding and processing, and easy coloring. It is widely used ...
