Abstract

The invention relates to a fan blade and a preparation method thereof. The axial fan blade with a reinforced sweepforward blade is prepared from, by mass, 76-89% of PP, 15-25% of glass fiber, 1.0-5.0% of carbon fiber, 3.0-10% 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 lauryl amide, 0.2-1.0% of silver-loaded inorganic antibacterial agent, 0.5-2.0% of ethylene bis-stearamide, 0.5-3.0% of methyl methacrylate-butadiene-styrene copolymer, 0.5-2.0% of halogen free flame retardant, 0.5-2.0% of anti-oxidant, 0.1-1.0 part of light stabilizer and 0.1-1.0% of heat stabilizer. The axial fan blade with the reinforced sweepforward blade has a high heat resistance, chemical corrosion resistance, anti-aging, anti-moulding, anti-ultraviolet properties and the like, the density and hardness are high, the size change is small, and the tensile strength of the plastic material is increased. At the same time, the axial fan blade with the reinforced sweepforward blade has the anti-static, antimicrobial, fire-retardant properties, and increased anti-aging property and a thermal decomposition performance.

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 reinforced with forward-swept blades 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. There will be a problem of increased vibration and noise. Contents of the invention [0004] In order to solve the above-mentioned technical problems,...
