Abstract

The invention relates to a mixed flow fan blade and a preparation method thereof. The fan blade is produced by injection moulding of the following materials which comprise, by mass percentage, 75-90% of PP, 10-30% of glass fiber, 1.0-5.0% of carbon fiber, 3.0-15% of mica, 0.1-1.5% of silane coupling agent DB792, 0.1-1.5% of silane coupling agent kh560, 0.2-2.0% of cyclic anhydride type compatibilizer, 0.5-1.0% of ethoxylated lauryl amide, 0.2-1.0% of silver loaded inorganic antibacterial agent, 0.5-2.0% of microcrystalline wax, 0.5-3.0% of hyperbranched polymer, 0.5-2.0% of halogen-free flame retardant agent, 0.5-2.0% of anti-oxidant, 0.1-1.0% of light stabilizer and 0.1-1.0% of heat stabilizer. The mixed flow fan blade has high heat-resistant, anti-chemical-corrosion, anti-aging, mouldproof, ultraviolet-radiation-proof properties and the like, and is high in density and hardness, and small in size deformation. The preparation method of the mixed flow fan blade enhances the tensile strength of a plastic material.

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 oblique flow fan blades for 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, th...
