Abstract

The invention relates to a fan blade and a preparation method thereof. The centrifugal fan blade is prepared by injection molding of the following materials by mass percentage: 75-85% of ABS (acrylonitrile butadiene styrene), 10-20% of glass fibers, 0.5-2.0% of aramid fibers, 0.1-1.5% of a silane coupling agent DB792, 0.2-2.0% of an annular anhydride compatilizer, 0.5-1.0% of ethoxylated lauramide, 0.2-1.0% of an antibacterial agent ECOFRESH, 0.5-2.0% of microcrystalline wax, 0.5-3.0% of EVA (ethylene/vinyl acetate), 0.5-2.0% of a halogen-free flame retardant, 0.5-2.0% of an antioxidant, 0.1-1.0% of a light stabilizer and 0.1-1.0% of a heat stabilizer. The centrifugal fan blade has higher properties of heat resistance, chemical corrosion resistance, aging resistance, mold prevention, ultraviolet radiation protection and the like, is high in density and hardness and small in size distortion, and the tensile strength of a plastic material is enhanced. Meanwhile, the centrifugal fan blade also has antistatic, antibacterial and flame retardant properties, and the aging characteristic and the thermal decomposition characteristic are 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 centrifugal fan blades of air conditioners are made of ordinary glass fiber reinforced AS, ABS 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 ...
