Polyformaldehyde turbine for weather-resistant automobile windshield wiper motor and preparation method of polyformaldehyde turbine

Abstract

The invention relates to automobile part manufacturing, in particular to a weather-proof polyformaldehyde turbine for an automobile windshield wiper motor and a preparation method of the weather-proof polyformaldehyde turbine. The invention relates to a polyformaldehyde turbine for a weather-resistant automobile windshield wiper motor. The polyformaldehyde turbine comprises the following components in parts by mass: 100 parts of a polyformaldehyde raw material, 2-4 parts of a stabilizer, 1.5-2.5 parts of an antioxidant, 2-4 parts of an emulsifier, 0.15 part of a dispersion lubricant, 1-2 parts of an ultraviolet light absorber and 2-5 parts of metal oxide. According to the invention, the polyformaldehyde raw material is blended with other micromolecular modifiers to modify polyformaldehyde, so that the polyformaldehyde has the advantages of ultraviolet light resistance stability, heat sample resistance stability and hot water resistance stability, and the durability of the product is improved.

Description

technical field [0001] The invention relates to the manufacture of auto parts, in particular to a weather-resistant polyoxymethylene turbine for automobile wiper motors and a preparation method thereof. Background technique [0002] The wiper motor is driven by the motor, and the rotary motion of the motor is converted into the reciprocating motion of the wiper arm through the link mechanism, so as to realize the wiper action. Generally, the wiper can work when the motor is turned on. By selecting the high-speed and low-speed gear, the motor can be changed. The size of the current, so as to control the motor speed and then control the speed of the scraper arm. [0003] The current wiper motor turbine is generally produced by injection molding to obtain turbine parts with light weight and high strength. However, the general injection molding method directly heats and injects the raw materials, and the product has low resistance and is easy to age and become brittle. SUMMARY...
