Abstract

The invention relates to a mixed flow fan blade and a preparation method thereof. The fan blade is produced by injection moulding of the following materials which comprise, by mass percentage, 75-90% of PP, 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 DB792, 0.1-1.5% of silane coupling agent kh560, 0.2-2.0% of cyclic anhydride type compatibilizer, 0.5-1.0% of ethoxylated lauryl amide, 0.2-1.0% of silver loaded inorganic antibacterial agent, 0.5-2.0% of microcrystalline wax, 0.5-3.0% of hyperbranched polymer, 0.5-2.0% of halogen-free flame retardant agent, 0.5-2.0% of anti-oxidant, 0.1-1.0% of light stabilizer and 0.1-1.0% of heat stabilizer. The mixed flow fan blade has high heat-resistant, anti-chemical-corrosion, anti-aging, mouldproof, ultraviolet-radiation-proof properties and the like, and is high in density and hardness, and small in size deformation. The preparation method of the mixed flow fan blade enhances the tensile strength of a plastic material.

Example Embodiment

[0019] Example 1
[0020] A diagonal flow fan blade which is injection molded from the following materials in terms of mass percentage:
[0021]
[0022] The above-mentioned preparation method of diagonal flow blades, the method includes the following steps: mixing PP resin, mica, silane coupling agent DB792, and silane coupling agent kh560 in a high-mixer for 10-15 minutes; place in a twin-screw extruder Add glass fiber, carbon fiber and other additives from the side feed port to the main feed port for melt extrusion. After cooling in the water tank, the pellets are cut, then dried and mixed to obtain injection pellets; the pellets are fed into the injection molding machine The diagonal flow fan blade is obtained by injection molding in the process.
