Embodiment Construction

[0014] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0015] A trailer body painting process, characterized in that: comprising the following steps:

[0016] (1), pre-painting treatment

[0017] a. Substrate pretreatment: When taking steel substrates, if the corrosion is serious, use high-pressure water jets to scour the steel substrates to remove the rusted materials on the steel substrates; remove the rusted steel substrates with throwing The shot machine is used for polishing treatment to polish the surface of the steel substrate;

[0018] b. Sand blasting treatment: Before entering the sand blasting process of the whole vehicle, first remove the residual welding slag and spatter around the weld, and then spray quartz sand at high speed, and focus on the positions that are not conducive to operat...

Abstract

The present invention relates to the vehicle field, specifically a trailer body painting process, comprising the following steps: (1), pre-painting treatment: a, substrate pretreatment; b, sandblasting treatment; (2), painting And paint film drying: a. The choice of paint; b. The coating operation environment requires that the surface temperature of the steel plate should be higher than 5°C or the relative humidity should be less than 70%; c. Spraying operation. The coating process of the present invention uses high-pressure water jets to scour the steel substrate, which can effectively avoid the flying of dust when cleaning the steel substrate, and the addition of sprayed paint and mint juice helps to keep the car body fresh. Reduce driver fatigue.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a coating process for a trailer body. Background technique [0002] The automobile painting process can generally be divided into two parts: one is the surface treatment of the metal before painting, also called pre-treatment technology; the other is the construction process of painting. Surface treatment mainly includes the removal of oil, dust, rust on the surface of the workpiece, and the removal of the old paint layer during repair work, so as to improve the surface condition of the workpiece. Including mechanical processing and chemical treatment of the workpiece surface according to various specific conditions, such as phosphating, oxidation and passivation treatment. The existing automobile painting process can no longer meet the actual requirements for the use of modern car bodies, and needs further improvement. Contents of the invention [0003] Aiming at the problems in the ...
