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 cross-flow fan blade and a preparation method thereof. The cross-flow fan blade is formed by injection moulding of the following materials in percentage by mass: 80-90% of PP, 10-15% of glass fiber, 1.0-5.0% of carbon fiber, 5.0-10% of mica, 0.1-1.5% of a silane coupling agent KH560, 0.1-1.5% of a silane coupling agent KBM-403, 0.2-2.0% of cyclic anhydride type compatilizer, 0.5-1.0% of ethoxylated lauramide, 0.2-1.0% of a silver-loaded inorganic antibacterial agent, 0.5-2.0% of a microcrystalline wax, 0.5-3.0% of hyperbranched polymer, 0.5-2.0% of a halogen-free flame retardant, 0.5-2.0% of an antioxidant, 0.1-1.0% of a light stabilizer and 0.1-1.0% of a heat stabilizer. The cross-flow fan blade has relatively high heat resistance, chemical corrosion resistance, aging resistance and mildew prevention, is high in density and hardness and small in size deformation, and the tensile strength of the plastic material is increased.

Description

technical field [0001] The invention relates to a cross-flow fan blade 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 pro...
