Abstract

The invention belongs to the technical field of composite materials, and particularly relates to a resin composite material with an abnormal sound prevention function suitable for air conditioner parts and a preparation method thereof. The resin composite material comprises the following raw material components in parts by weight: 5-30 parts of compound PPO, 5-30 parts of PP, 20-70 parts of PS, 1-5 parts of a paraffin-based graft copolymer, 5-10 parts of a compatilizer, 2-5 parts of a flexibilizer, 1-5 parts of a plasticizer, 0.3-0.6 part of an antioxidant, 0.5-1.0 part of a lubricant, 1.5-2.5parts of LLDPE, 0.5-2.0 parts of a slipping agent, 2-4 parts of a viscosity reducer and 0.5-2.0 parts of an acid acceptor. The material can reduce the vibration frequency of a workpiece after injection molding so that the purpose of reducing the abnormal sound of the plastic part is achieved, the problem of friction abnormal sound of the air conditioner part is solved from the aspect of materials, the effect is remarkable, the mode is simple and the use prospect is good.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a resin composite material suitable for air-conditioning parts and having an anti-abnormal noise function and a preparation method thereof. Background technique [0002] After the air conditioner is running or shutting down, due to sudden changes in temperature, the plastic shell and internal plastic parts will expand with heat and contract with cold, and thus make a "click" sound. According to the analysis given by the air-conditioning laboratory, it is mainly due to the sliding displacement of the plastic parts after thermal expansion and contraction, and the plastic parts make abnormal noises through the friction generated by the sliding displacement. At present, the main methods to prevent the abnormal noise caused by the friction include adding gaskets, non-woven fabric insulation, applying lubricating oil, adding anti-abnormal noise coating lubricati...
