Problems solved by technology

[0003] Most of the existing cross-flow fan blades for air conditioners are made of ordinary glass fiber reinforced ABS, 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, and vibration will occur during use. The problem of increased noise

Abstract

The invention relates to a fan and a preparing method thereof. A cross-flow fan is prepared from, by mass, 75-90% of AS, 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 DB 792, 0.1-1.5% of silane coupling agent kh 560, 0.2-2.0% of cyclic anhydride type compatilizer, 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 EVA, 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 through injection molding. The cross-flow fan has high heat resistance, chemical corrosion resistance, ageing resistance, mouldproof performance and ultraviolet radiation performance, is high in density and hardness and small in size distortion and improves 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 cross-flow fan blades for air conditioners are made of ordinary glass fiber reinforced ABS, 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, 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 ...
