Problems solved by technology

[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

Abstract

The invention relates to a fan blade and a preparation method of the fan blade. The centrifuging fan blade is prepared through injection moulding from the following materials by mass percent: 75-85% of ABS, 10-20% of glass fiber, 1.0-2.0% of aramid fiber, 0.1-1.5% of a silane coupling agent DB792, 0.1-1.5% of a silane coupling agent kh560, 0.2-2.0% of a cyclic anhydride type compatilizer, 0.5-1.0% of ethyoxyl lauramide, 0.2%-1.0% of antibacterial agent ECOFRESH, 0.5-2.0% of microcrystalline wax, 0.5-3.0% of EVA, 0.5-2.0% of a halogen-free flame retardant, 0.5-2.0% of antioxygen, 0.1-1.0% of a light stabilizer, and 0.1-1.0% of a heat stabilizer. The centrifuging fan blade has the higher performances of heat resistance, resistance to chemical attack, ageing resistance, mildew prevention, protection from ultraviolet rays and the like, is high in density and hardness and small in size deformation, and improves 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 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 ...
