Abstract

The invention relates to a fan blade and a preparation method thereof. The cross-flow fan blade with the variable air outlet angle is prepared by injection molding of following materials: by mass, 70-85% of AS, 15-25% of glass fibers, 1.0-4.0% of carbon fibers, 0.1-1.5% of silane coupling agent DB792, 0.1-1.5% of silane coupling agent KBM-40, 0.2-2.0% of annular anhydride compatibilizer, 0.5-1.0% of ethoxylated lauramide, 0.2-1.0% of silver-loaded inorganic antibacterial agent, 0.5-2.0% of polyethylene wax, 0.5-3.0% of methyl methacrylate and butadiene and styrene terpolymer, 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. The cross-flow fan blade with the variable air outlet angle has high heat resistance, chemical corrosion resistance, aging resistance, mildew resistance, ultraviolet radiation resistance and other performance, is high in density and hardness and small in size distortion, and increases the tensile strength of plastic materials.

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 air conditioner cross-flow fan blades with variable air outlet angle are made of ordinary glass fiber reinforced AS, 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. , the problem of increased vibration and noise will occur during use. Contents of the invention [0004] In order to solve the above-mentione...
