Abstract

The invention relates to a fan blade and a preparation method. An oblique flow fan blade is prepared by injecting and molding the following materials in percentage by mass: 75-90 percent of ABS, 5-10 percent of glass fibers, 1.0-5.0 percent of aramid fibers, 0.1-1.5 percent of saline coupler DB792, 0.2-2.0 percent of cyclic anhydride compatilizer, 0.5-1.0 percent of ethoxy lauramide, 0.2-1.0 percent of an antibacterial agent ECOFRESH, 0.5-2.0 percent of polyethylene wax, 0.5-3.0 percent of hyperbranched polymer, 0.5-2.0 percent of halogen-free flame retardant, 0.5-2.0 percent of antioxidant, 0.1-1.0 percent of light stabilizer and 0.1-1.0 percent of thermal stabilizer. The oblique flow fan blade has relatively high performances of heat resistance, chemical corrosion resistance, aging resistance, mildew prevention, ultraviolet radiation resistance and the like, has high density, high hardness and small size deformation, and can be used for improving the tensile strength of plastic materials. Furthermore, the oblique flow fan blade has anti-static and antibacterial performances and flame retarding performance, and the aging performance and thermal decomposition performance can be improved.

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 air conditioner oblique flow fan blades 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 fir...
