CN104275293A - Paint-spraying treatment process of electric vehicle metal plate - Google Patents

Abstract

The invention discloses a paint-spraying treatment process of an electric vehicle metal plate. The paint-spraying treatment process of the electric vehicle metal plate is characterized by comprising the following process steps: (1) brushing emulsion, namely coating one layer of the emulsion on the electric vehicle metal plate; (2) scraping putty powder, namely after the emulsion on the metal plate is dried, scraping the putty powder on a part, needing to be subjected to paint spraying, of the metal plate; drying and polishing; (3) coating priming paint, namely coating the priming paint on the metal plate on which the putty powder is scratched; (4) spraying finishing paint, namely shielding one part which does not need to be subjected to paint spraying and spraying paint on the metal plate by a paint spraying manner, and drying; and (5) polishing, namely polishing the metal plate sprayed with the finishing paint and sticking a label. According to the paint-spraying treatment process of the electric vehicle metal plate, the disadvantages in the prior art are overcome; the emulsion is brushed to further isolate air and prevent the metal plate from being rusted; the appearance of the metal plate is flat by scraping the putty powder and polishing; finally, the priming paint is brushed and the finishing paint is sprayed so that the times of brushing the priming paint can be reduced under the precondition that the dustproof capability is guaranteed; and the cost is effectively lowered, the dustproof capability is high, the appearance is beautiful and the application range is wide.

Description

Electric motor car panel beating spraying process

Technical field

The present invention relates to electric motor car panel beating lacquering technologies field, specifically belong to electric motor car panel beating spraying process.

Background technology

Existing panel beating spraying process: scrape first floor powder of lacquer putty for use on → two layers of powder of lacquer putty for use on → polishing of polishing → scrape → upper priming coat → upper → topcoating → polishing of priming; Gloss and the antirust ability on surface is ensured by multilayer powder of lacquer putty for use on and multilayer priming paint, but electric motor car is located this process due to the market price and is increased cost greatly undoubtedly, some producers come cost-saving by the treatment process reducing powder of lacquer putty for use on and priming paint, but have and cannot ensure antirust ability.

Summary of the invention

The object of this invention is to provide electric motor car panel beating spraying process, overcome the deficiencies in the prior art, further completely cut off air placement by brush latex to get rusty, ensure the smooth of panel beating outward appearance, last priming and topcoating process by Puttying powder, polishing again, ensure the number of times reducing priming under antirust ability prerequisite, effectively save cost, antirust ability is strong simultaneously, and outward appearance is beautiful, and usage range is wide.

The technical solution used in the present invention is as follows:

Electric motor car panel beating spraying process, is characterized in that: its processing step is as follows:

(1) brush latex: smear one deck latex by electric motor car panel beating;

(2) Puttying powder: needs powder of lacquer putty for use on is scraped at the position of spraying paint at panel beating after having waited the latex on panel beating to do, polishing after dry;

(3) priming paint: be coated with priming on the panel beating having scraped powder of lacquer putty for use on;

(4) topcoating: by not so blocking of not needing to spray paint, sprays paint to panel beating by the mode of spraying paint, dry;

(5) polishing: polishing is carried out to the panel beating having sprayed finish paint, the process of labeling will.

Described emulsion thickness is 0.2MM.

Described brush latex preorder is provided with rust cleaning and antirust treatment.

Compared with the prior art, beneficial effect of the present invention is as follows:

The present invention further completely cuts off air placement by brush latex and gets rusty, the smooth of panel beating outward appearance is ensured again by Puttying powder, polishing, last priming and topcoating process, ensureing the number of times reducing priming under antirust ability prerequisite, effectively save cost, antirust ability is strong simultaneously, and outward appearance is beautiful, and usage range is wide.
