Description

Wear-resistant matte baking varnish coating for electric vehicle shell

Technical Field

The utility model belongs to the technical field of the baking finish coating, especially, relate to a wear-resisting type electric motor car casing mute light baking finish coating.

Background

Baking finish is actually a paint spraying manufacturing process, and the method comprises the following steps: spraying a plurality of layers of paint on the base material polished to a certain roughness, and baking and shaping at high temperature; the process has the advantages of high requirements on the performance of the paint and good color rendering property. After the electric vehicle shell is formed, a protective coating needs to be coated, wherein a baking varnish coating is one of the more common coatings. The matte paint is a paint with lower gloss than the bright paint, so that the matte paint can avoid light pollution, is convenient to maintain, and is widely applied to electric vehicles.

The matte baking varnish coating used on the existing electric vehicle shell has the problems of poor wear resistance and easy peeling and falling after high-temperature exposure.

SUMMERY OF THE UTILITY MODEL
