Problems solved by technology

[0002] High-impact polystyrene (HIPS) material is a two-phase system polymer composed of elastomeric rubber and continuous styrene rubber. Because of its low price, excellent processing performance and mechanical properties, HIPS is widely used in various household appliances. However, the shrinkage rate of HIPS changes greatly in the alternating cold and hot environment, the parts are easy to deform, and the dimensional stability is poor, which seriously limits its application range.

The material comprises, by weight, 60-80 parts of HIPS resin, 3-10 parts of a rubber composite material, 8-20 parts of a reinforcing agent, 3-10 parts of a blocking agent, 0.3-1.5 parts of a weather-proof agent, 0.1-0.6 part of an antioxidant and 0.1-0.6 part of a lubricant. The material not only has excellent strength, toughness and dimensional stability, but also can play a role in vibration and noise reduction, can solve the common abnormal sound problem of current household appliances and improve the living environment of people, and is low in comprehensive cost and wide in application range.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a low-shrinkage HIPS composite material for solving abnormal noise and a preparation method thereof. Background technique [0002] High-impact polystyrene (HIPS) material is a two-phase system polymer composed of elastomeric rubber and continuous styrene rubber. Because of its low price, excellent processing performance and mechanical properties, HIPS is widely used in various household appliances. However, the shrinkage rate of HIPS changes greatly in the alternating cold and hot environment, the parts are easy to deform, and the dimensional stability is poor, which seriously limits its application range. [0003] Air-conditioning products cause noise pollution due to size changes, vibration and resonance of different parts of the product when they alternate between hot and cold. Noise pollution has become a contemporary worldwide problem and is endangering people's ph...
