Problems solved by technology

[0003] Most of the existing cross-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

Abstract

The invention relates to a fan and a preparation method thereof. A cross-flow fan is injection moulded from the following materials in percentage by mass: 80-90% of ABS, 5-15% of glass fiber, 0.2-1.0% of carbon fiber, 0.1-1.5% of silane coupling agent DB792, 0.1-1.5% of silane coupling agent kh560, 0.2-2.0% of cyclic acid anhydride type compatilizer, 0.5-1.0% of ethoxylated 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 halogen-free flame retardant, 0.5-2.0% of antioxidant, 0.1-1.0% of light stabilizer and 0.1-2.0% of heat stabilizer. The oblique-blade cross-flow fan has relatively high properties in heat resistance, chemical corrosion resistance, aging resistance, mould prevention, ultraviolet radiation prevention and the like and high density and hardness and little size distortion and enhances the tensile strength of a plastic material. Meanwhile, the oblique-blade cross-flow fan also has static resistance, antibacterial property and flame retardation and enhances the aging property and thermal decomposition property.

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 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 ...
