Abstract
The invention discloses a coating process for an iron plate part of an electric vehicle. The coating process comprises the following steps: (1) surface treatment, wherein a wax layer on the surface is removed at first, then water milling is performed by clear water to remove cleaning liquid, drying is performed, and the iron plate part is subjected to surface dust scraping treatment; (2) primer spraying, wherein a primer adopts an inorganic waterborne zinc-rich coating; (3) middle coating spraying, wherein three layers of middle coating primers are applied respectively; (4) red plaster supplementation; (5) top coating spraying, wherein spraying is performed by adopting a spray gun in a circular motion mode, and the spray gun is moved outwards from the center; finally check and decoration are performed. The primer adopts the inorganic waterborne zinc-rich coating, has excellent mechanical property and anti-rust performance, is oil-resistant, solvent-resistant, high-temperature-resistant, safe and environment-friendly, and realizes zero VOC (volatile organic compound) discharge; moreover, the operation is simple and the production efficiency is greatly improved.

Traditional solvent based coating can discharge a large amount of organic solvent (VOC), VOC has multiple harmfulness to human body and environment, this kind of coating contains a large amount of volatile organic matters, in use not only waste resource, also cause environmental pollution, and existing coating process is comparatively loaded down with trivial details, production efficiency is low.
Summary of the invention
Object of the present invention is intended to solve the deficiencies in the prior art, and provides a kind of electric motor car iron plate part coating process of easy to operate, saving resource, preventing pollution environment.
The present invention for achieving the above object, by the following technical solutions: a kind of electric motor car iron plate part coating process, comprises following processing step:
(1) surface treatment:
Iron plate part strip first uses 150
#waterproof abrasive paper dips in 8112 metal cleaner water mills, then with clear water water mill removing cleaning fluid, carries out surface and scrapes ash process: first scrape one atomized ash after drying to iron plate part, dry after polishing dries up and scrape one atomized ash again, again carry out oven dry polishing and dry up;
It is as follows that grey method is scraped on described surface: taken out in right amount by atomized ash, after fully concocting in the ratio of 50:1 and curing agent, evenly scrape on rejected region surface with grey cutter, be as the criterion with smooth, that can not scrape is too thick, then pushes in barn, toasts, make it harden, toast 20 minutes under the environment of 50 DEG C;
(2) primer spray:
Priming paint adopts inorganic aqueous zinc-rich paint,
Priming paint is prepared: binding agent: 20 parts ~ 30 parts, zinc powder: 70 parts ~ 80 parts,
Basecoat paint: basecoat paint in iron plate surface, has been sprayed rear drying, right rear ash-scraping by employing spraying equipment, again dry;
(3) be coated with in spray
By in prime and pour spray gun into, be applied to whole putty surface by priming in ground floor, after leaving standstill a period of time, solvent evaporation in priming in making (until in prime lose part gloss) apply again two-layer in prime, then dry.
(4) red ash is mended
Red ash is mended to iron plate part, completes rear ash-scraping and drying, baking temperature 75 DEG C ~ 78 DEG C, with 1500 after dry
#liquid honing, carries out drying after polishing again, by clean for iron plate part surface wipes after drying;
(5) topcoating
Adopt spray gun to spray, spraying adopts circular movement pattern, makes spray gun from center outward movment; Dry after having sprayed, dried rear employing 1500
#fine sandpaper sanding and polishing, finally carries out checking and modifying.
As preferably, in described step (2), binding agent is made up of following constituent mass percentage: potassium silicate: 50 parts ~ 60 parts; Silicone acrylic emulsion: 20 parts ~ 30 parts; Ludox: 10 parts ~ 30 parts;
As preferably, in described step (2), zinc powder is 500 order zinc powders;
The invention has the beneficial effects as follows: priming paint of the present invention adopts inorganic aqueous zinc-rich paint, it has excellent mechanical performance and rustless property, oil resistant, solvent resistant, high temperature resistant, Diamond Search discharge, safety and environmental protection, and simple to operate, substantially increases production efficiency.
