Abstract

The invention discloses an automobile air conditioner fan shroud and a preparation method thereof. The preparation method comprises the following steps: 1) soaking montmorillonite and bamboo charcoal ash into a hydrochloric acid solution, carrying out ultrasonic vibration, and filtering to obtain a filter residue; 2) smelting PVC (polyvinyl chloride), ABS (acrylonitrile-butadiene-styrene copolymer), an ethylene-propene-nonconjugated diene terpolymer, PEI (polyetherimide), melamine cyanurate, diisodecyl phthalate, zinc oxide, rare earth oxide, vanadic oxide, citric acid, starch and the filter residue; carrying out curing and formation to obtain the automobile air conditioner fan shroud. The automobile air conditioner fan shroud is excellent in weatherability and mechanical property; moreover, the preparation method is simple in step and high in raw material availability.

Description

technical field [0001] The invention relates to automobile air conditioner components, in particular to an automobile air conditioner wind protection ring and a preparation method thereof. Background technique [0002] The windshield of the car air conditioner is an important part of the car air conditioner. It plays the role of protecting the fan blades and guiding the flow, and can also improve the efficiency of the wind. Very serious, only through the diversion of the windshield to improve the efficiency of the air conditioning fan. At the same time, the distance between the fan and the wind protection ring is generally controlled within a certain range. If the distance is too large or too small, the air diversion effect of the wind protection ring will be greatly reduced. [0003] At present, automotive air conditioner windshields are generally made of polymer materials. Due to the large temperature difference between the two sides of the car air conditioner windshield...
