Integrated method of coating, intermediate coating, color-registering for cab

Abstract

The invention discloses a process method which integratedly implements the prime gluing, intermediate coating and color-registering for an automobile cab. The method comprises the following steps: (1) coating equipment is adopted for spraying the cab welding seam glue, the vehicle bottom coating; (2) the spraying welding seam glue, the vehicle bottom coating cab is changed into intermediate coating paint spray chamber for intermediate coating; (3) the spraying of the color-registering part is conducted according to requirements; (4) the cab which passes through the technology courses of prime gluing, intermediate coating and color-registering is integratedly dried. The color-registering part adopts shielding material for shielding, and the whole spraying of the cab is conducted, after the drying is conducted, the shielding material can be removed for recycling. The application of the invention lies in that the energy consumption caused by repeated drying of the cab is avoided, the color-registering production process for cab is innovated, the production efficiency is increased, and the energy-consumption is reduced, and the invention has good economic and social benefits.

Description

technical field [0001] The invention relates to a coating process for an automobile cab, in particular to an integrated process of cab glue coating, intermediate coating and color registration. Background technique [0002] At present, in the automotive painting process, in order to meet the sealing requirements of the cab and pursue high weather resistance and high decorative performance, weld glue extrusion coating, underbody paint spraying, intermediate coating spraying and special pattern filming technologies are widely used. [0003] In the traditional production process, weld glue extrusion coating, vehicle bottom paint spraying-drying-intermediate coating spraying-drying-color registration spraying-drying-cab topcoat-overall drying are generally used. Dry process method. Using this process method requires repeated baking of the cab and thorough drying of each coating, which requires 2 additional drying chambers. At the same time, each coating must be equipped with a ...

AI Technical Summary

Problems solved by technology

Using this process method requires repeated baking of the cab and thorough drying of each coating, which requires 2 additional drying chambers. At the same time, each coating must be equipped with a fixed location and special spraying equipment. Add one spray booth for intermediate coating and one spray booth for color registration, so there are problems of large energy consumption and large area occupied by process layout, which does not meet the requirements of the concept of "environmental friendliness" for automobile painting

[0004] In the traditional coating production line for intermediate coating spraying, the production method of intermediate coating spraying on the topcoat line is often used, and then the topcoat is sprayed twice. This production method affects the improvement of production efficiency and causes a burden on energy consumption.

[0005] It is difficult to meet the requirements of low cost and low energy consumption by traditional process methods. The use of traditional high-temperature curing intermediate coatings mainly restricts the performance of high-temperature drying of intermediate coatings, the configuration of coloring coatings and the production of masking materials.
