Abstract

The invention relates to a fan blade and a preparation method thereof. An axial flow fan blade is prepared by, by mass, 80-90% of AS, 10-15% of glass fibers, 5.0-10.0% of carbon fibers, 0.1-1.5% of silane coupling agent DB792, 0.1-1.5% of silane coupling agent KBM-403, 0.2-2.0% of cyclic anhydride compatibilizer, 0.5-1.0% of ethoxylated lauramide, 0.2-1.0% of silver-loaded inorganic antibacterial agent, 0.5-2.0% of butyl stearate, 0.5-3.0% of ethylene-vinyl acetate copolymer, 0.5-2.0% of halogen-free flame retardant, 0.5-2.0% of antioxidant, 0.1-1.0% of light stabilizer and 0.1-1.0% of heat stabilizer in an injection molding mode. The axial flow fan blade has high heat resistance, chemical corrosion resistance, aging resistance, mould resistance, ultraviolet radiation resistance and other performance, and is high in density and hardness and small in size deformation, and the tensile strength of a plastic material is improved.

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 fan blades 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 and noise will be generated during use. Increased problem. Contents of the invention [0004] In order to solve the above-mentioned technical problems, the first object of t...
