Problems solved by technology

[0003] Most of the existing axial flow impellers for air conditioners are made of ordinary glass fiber reinforced ABS, AS or PP materials. Due to their insufficient rigidity and high temperature resistance, they are prone to deformation during transportation and after long-term use, and vibration will occur during use. The problem of increased noise

Abstract

The invention relates to a fan blade and a preparation method thereof. An axial impeller is prepared from the following materials in percentage by mass through injection molding: 75 to 90 ppercent of AS (Acrylonitrile-Styrene), 15 to 20 percent of glass fiber, 1.0 to 5.0 percent of carbon fiber, 5.0 to 15 percent of mica, 0.1 to 1.5 percent of silane coupling agent kh 560, 0.1 to 1.5 percent of silane coupling agent KBM 403, 0.2 to 2.0 percent of cyclo-anhydride type compatilizer, 0.5 to 1.0 percent of ethoxylated lauramide, 0.2 to 1.0 percent of antibacterial agent ECOFRESH, 0.5 to 2.0 percent of microcrystalline paraffin, 0.5 to 3.0 percent of EVA (Ethylene-Vinyl Acetate), 0.5 to 2.0 percent of halogen-free flame retardant, 0.5 to 2.0 percent of antioxidant, 0.1 to 1.0 percent of light stabilizer and 0.1 to 1.0 percent of thermal stabilizer. The axial impeller disclosed by the invention has higher properties of heat resistance, chemical corrosion resistance, aging resistance, mildew resistance, ultraviolet radiation resistance and the like, the density is high, the hardness is high, the size deformation is small, and the tensile strength of a plastic material is increased.

Description

technical field [0001] The invention relates to wind blades and a preparation method thereof. Background technique [0002] With the improvement of living standards, people pay more and more attention to the requirements of the living environment. As an air conditioner used in an indoor airtight environment, its impact on fan noise is also increasingly concerned. The air conditioner indoor unit fan is the key component of the air supply of the air conditioner, so it has an important impact on the size of the indoor fan noise. [0003] Most of the existing axial flow impellers for air conditioners are made of ordinary glass fiber reinforced ABS, AS or PP materials. Due to their insufficient rigidity and high temperature resistance, they are prone to deformation during transportation and after long-term use, and vibration will occur during use. The problem of increased noise. Contents of the invention [0004] In order to solve the above-mentioned technical problems, the f...
