The materials for injection molding process comprises, by mass, 70-90% of PP, 10-30% of glass fiber, 1.0-5.0% of carbon fiber, 5.0-20% of mica, 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 alkyl amine, 0.2-1.0% of silver loaded inorganic antibacterial agent, 0.5-2.0% of polyethylene wax, 0.5-3.0% of EVA, 0.5-2.0% of HFFR, 0.5-2.0% of anti-oxidant, 0.1-1.0% of light stabilizer and 0.1-1.0% of heat stabilizer. The gas assisted injection molding axial-flow fan blade has a high heat resistance, chemical corrosion resistance, anti-aging, anti-moulding, anti-ultraviolet radiation and the like, the fan blade is high in density and hardness, small in size deformation, and the tensile strength of the 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 gas-assisted forming axial flow fan blades of air conditioners are made of ordinary glass fiber reinforced PP, PP or PP materials. Due to their insufficient rigidity and high temperature resistance, they are prone to deformation during transportation and after long-term use. There will be a problem of increased vibration and noise. Contents of the invention [0004] In order to solve the above-mentioned technical proble...
