New process for painting container of engineering dump truck

Abstract

The invention provides a new process for painting a container of an engineering dump truck, which comprises the following processes of pre-degreasing, degreasing, washing, surface adjusting, phosphating, washing, drying and spraying paint integrating primer with finishing paint. The paint integrating the primer with the finishing paint is sprayed after the container of the engineering dump truck is phosphated integrally so as to simplify the conventional double-spraying and double-drying process for the container of the engineering dump truck. The new process integrally phosphates the container of the engineering dump truck, simplifies the conventional double-spraying and double-drying process for the container of the engineering dump truck by using the paint integrating the primer with the finishing paint, provides a pretreatment process and a single-spraying and single-drying process for the engineering container of the vehicle, and has the advantages of less investment, small occupied area, low operating and maintenance cost, simple and practicable process, improvement on product quality, reduction in production cost and the like.

Description

technical field [0001] The invention relates to a coating process for cargo boxes, in particular to a coating process for automotive engineering cargo boxes, and belongs to the automobile manufacturing industry. Background technique [0002] At present, the known painting process of the cargo box of the self-unloading engineering vehicle is: derusting the surface of the cargo box → degreasing the surface of the cargo box with gasoline → drying the surface of the cargo box naturally → spraying anti-rust primer → drying the primer → Spray the topcoat of the cargo box → dry the topcoat (two-spray and two-baking process). The process uses gasoline, which is prone to fire and has serious safety hazards. In this process, there are too many manual processes, the quality is difficult to control, and the production efficiency is low. It is difficult to achieve large-scale production and the production cost is high. And it is greatly affected by the weather and the site. When the con...
