Abstract

The invention discloses an axial-flow fan of an automobile air conditioner and a preparation method thereof. The preparation method comprises the following steps: 1) blending and mixing PC (polycarbonate), ASA (acrylonitrile styrene acrylate copolymer), CPE (chlorinated polyethylene), p-tert-butylphenol-formaldehyde resin, nano titanium dioxide, tungsten disulfide, calcium naphthenate, aspartic acid, tributyl citrate, triethylene tetramine, diazolidinyl urea, diatomite, carbon fibers, ethyl cellulose, boron nitride, potassium fluotantalate, diborane and silane coupling agents to form a mixture; and 2) curing the mixture, thus preparing the axial-flow fan of the automobile air conditioner. The automobile air conditioner prepared by the method has excellent mechanical properties. Meanwhile, the method is simple in steps and raw materials are easy to obtain.

Description

technical field [0001] The invention relates to an automobile air conditioner assembly, in particular to an automobile air conditioner axial flow fan blade and a preparation method thereof. Background technique [0002] Automobile air conditioner axial fan blade is an important part of the exhaust system of automobile air conditioner, which mainly plays the role of ventilation and heat dissipation. Since the axial-flow fan blades of the automobile air conditioner need to rotate continuously in the working process to play a corresponding role, the high-speed friction between the axial-flow fan blades of the automobile air conditioner and the air generates heat. [0003] At present, the axial flow fan blades of automobile air conditioners are all made of polymer materials. During the long-term friction and heat generation process, the mechanical properties of the axial flow fan blades of automobile air conditioners show a gradual decline trend. In the long run, the axial flow ...
