Abstract
The invention discloses a vehicle fender-guard paint spraying process. The vehicle fender-guard paint spraying process comprises the following steps that 1, surface treatment is carried out on a fender-guard, and dust, grease and an old film are removed; 2, the fender-guard after surface treatment is performed is subjected to moisture drying; 3, the dried fender-guard is ground; 4, flame treatment is performed, so that the surface of the fender-guard is oxidized; 5, electrostatic precipitation is carried out, burrs of the surface of the fender-guard due to electrostatic adsorption are removed, and cleanness of workpieces before spraying is ensured; 6, priming paint is sprayed, and protection on a fender-guard base material is enhanced; 7, finish paint is sprayed on the fender-guard after the priming paint is sprayed, and the thickness of the finish paint is greater than that of the priming paint; 8, lac varnish is sprayed, the finish paint coverage layer is prevented from being oxidized, metallic lustre of finish paint color is increased, and the fender-guard is more attractive; 9, the fender-guard after the lac varnish is sprayed is leveled out and aired; 10, the leveled and aired fender-guard is baked and cured; 11, the finished fender-guard after being sprayed with paint is obtained. The superior quality of the fender-guard which is subjected to paint spraying is ensured, and attractiveness is good.
Description
Technical field
The present invention relates to auto parts and components field, be specifically related to a kind of bumper lacquer spraying technique.
Background technology
Along with the raising day by day of China's living standard, as one of the main traffic instrument of present people, ordinary citizen family more and more come into by automobile.The lacquer spraying technique of current domestic automobile bumper is not perfect, cause the automotive trim carpet end product quality that processes and aesthetic property relatively poor, can not satisfy the demands of consumers, waste raw material simultaneously, improve production cost.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of bumper lacquer spraying technique, this lacquer spraying technique step is clear perfect, the bumper quality high-quality after spraying paint and aesthetic property is good.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of bumper lacquer spraying technique, comprises the following steps:
1) surface treatment is carried out to bumper, except dust, grease and old coating film;
2) bumper after effects on surface process carries out moisture oven dry;
3) bumper after oven dry is polished, remove bumper surface irregularity or damage position;
4) carry out flame treatment, make the surface oxidation of bumper, increase it to the absorption affinity of painting;
5) electrostatic precipitation, removes the burr of bumper surface due to Electrostatic Absorption, ensures the cleanliness factor of workpiece before spraying;
6) spray-applied primer, strengthens the protection to bumper base material;
7) to the bumper spray paint after spray-applied primer, the thickness of finish paint is greater than priming paint;
8) spray lac varnish, avoid finish paint layer oxidized, increase the metallic luster of finish paint color, make it more attractive in appearance;
9) the bumper levelling having sprayed lac varnish is dried;
10) baking-curing is carried out to the bumper that levelling dries;
11) bumper product after spraying paint is obtained.
A kind of bumper lacquer spraying technique of the present invention, by surface treatment,---------------------processing step of spraying lac varnish---levelling dries---baking-curing to spray paint process to bumper spray paint spray-applied primer electrostatic precipitation flame treatment, and ensure to spray paint the bumper quality high-quality after processing and aesthetic property is good in polishing in moisture oven dry.
Detailed description of the invention
A kind of bumper lacquer spraying technique described in the embodiment of the present invention, comprises the following steps:
1) surface treatment is carried out to bumper, except dust, grease and old coating film;
2) bumper after effects on surface process carries out moisture oven dry;
3) bumper after oven dry is polished, remove bumper surface irregularity or damage position; Then carry out surface to clean;
4) carry out flame treatment, make the surface oxidation of bumper, flame activates the oxygen molecule in air, makes them be formed on the surface of bumper and divides into groups with the polarity of carbon molecule.The increase of surface grouping polarity and oxidation decrease the surface tension of bumper, increase the absorption affinity of material matrix to paint.
5) electrostatic precipitation, removes the burr of bumper surface due to Electrostatic Absorption, ensures the cleanliness factor of workpiece before spraying; Capital equipment can use electrostatic precipitation rifle, electrostatic precipitation ion blower, electrostatic precipitation ion dedusting wind rod etc.; Ensure the color homogeneity of topcoat;
6) spray-applied primer, strengthens the protection to bumper base material;
7) to the bumper spray paint after spray-applied primer, provide required decorative colors, make outward appearance reach the requirement of design, and protect metal surface not by the erosion of external environment air, Acid Rain Pollution, prevent ultraviolet light from penetrating, greatly increase ageing resistance.The thickness of finish paint is greater than priming paint;
8) spray lac varnish, strengthen the anti-extraneous erosiveness of topcoat, protective topcoat coating is not oxidized, increases the metallic luster of finish paint color, makes product appearance more bright-coloured.
9) the bumper levelling having sprayed lac varnish is dried;
10) baking-curing is carried out to the bumper that levelling dries;
11) bumper product after spraying paint is obtained.
A kind of bumper lacquer spraying technique of the present invention, by surface treatment,---------------------processing step of spraying lac varnish---levelling dries---baking-curing to spray paint process to bumper spray paint spray-applied primer electrostatic precipitation flame treatment, and ensure to spray paint the bumper quality high-quality after processing and aesthetic property is good in polishing in moisture oven dry.
Last it is noted that the foregoing is only the preferred embodiments of the present invention; be not limited to the present invention; for a person skilled in the art; it still can regulate the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
