Abstract

The invention discloses a composite material, a preparation method thereof and air conditioner workpieces. The composite material comprises the following materials, in parts by weight: 50-70 parts of polypropylene, 10-20 parts of chopped glass fibers, 20-30 parts of an inorganic filler, 5-10 parts of a graft compatilizer, 0.2-0.8 part of an antioxidant, 0.5-2.0 parts of a lubricant, 0.1-1.0 part of a nucleating agent, and 0.5-2.0 parts of a rare earth oxide. The composite material has a low linear expansion coefficient and excellent dimensional stability, when the air conditioner workpieces are prepared by adopting the composite material, noise caused by thermal expansion and cold contraction in an air conditioner usage process can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular, the invention relates to a composite material, a preparation method thereof and an air conditioner. Background technique [0002] With the improvement of people's living standards, air conditioners have become a must-have for family life. They have the functions of adjusting indoor temperature and humidity and purifying the air. While bringing comfort to people, they also have the problem of noise pollution. [0003] Therefore, existing air-conditioning still needs to be improved. Contents of the invention [0004] The present invention proposes based on the inventor's discovery of the following problems and facts: [0005] The root cause of the noise of the indoor unit of the air conditioner is that the air conditioner parts (such as the chassis of the split machine, the volute tongue, the air outlet frame, the air duct assembly of the cabinet machine, the inner air outlet fra...
