Surface treatment technology of automobile trims

Abstract

The invention discloses a surface treatment technology of automobile trims. The technology includes the following steps that (1), the trims are placed into three alkaline tanks in sequence for ultrasonic washing; (2), ultrasonic washing is conducted on the trims subjected to alkaline washing; (3), the washed trims are subjected to ultrasonic washing; (4), the trims subjected to acid pickling are sequentially washed; (5), the washed trims are sequentially placed in two drying tanks for drying; (6), the dried trims are sequentially placed into three cooling tanks for cooling; (7), the cooled trims are placed in a primer tank for varnishing; (8), the trims are placed into the two drying tanks for drying; (9), the dried trims are sequentially placed into two cooling tanks for cooling; (10), the cooled trims are placed into a hardening tank for hardening; (11), the hardened trims are sequentially placed into three hot air drying tanks for heating and drying; (12), the trims are placed into the cooling tanks to be cooled for 7 min; (13) the trims are placed in a vacuum coating machine for coating.

Description

technical field [0001] The invention relates to a surface treatment process of an automobile trim, which belongs to the surface treatment process of plastic products. Background technique [0002] In the past, some of the trims in the car were made of glass, but in the event of a car accident or impact, the glass trim shattered, which would cause harm to the passengers and driver in the car. [0003] For the consideration of automobile safety, many car accessories are replaced by glass materials with plastic materials, but the surface of plastic materials is softer than glass materials, the light transmittance is not good, and it is easy to wear. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a surface treatment process for automotive trims. Through special processing, the surface of automotive plastic trims can be hardened to prevent scratches and maintain high transparency. [0005] In order to solve the prob...
