Description
【Technical field】
The present invention relates to the technical field of commercial car coating process, particularly a kind of special long-life strong adhesive force of commercial car
The technical field of coating process.
【Background technology】
With the high speed development of national economy and science and technology, Chinese industrial production capacity constantly improves, especially with service
The industry of premises product target, need to use substantial amounts of means of transport in industrial processes, commercial car is main conveyance
One of, metallic paint is widely used on vehicle, metallic paint, is called metal flash paint, added with fine metal in its paint base
Powder (such as aluminium powder, copper powder), after light is mapped on metal dust, it is reflected to come through air film again.Therefore, it appears that seem
Metal is glittering the same.This metal flash paint, give people a kind of pleasant, brisk, novel sensation, change metal dust
Shapes and sizes, it is possible to control the shining of metallic coating film；In the outside of metallic paint, generally also added with one layer of varnish
Protected.Metallic paint typically has water-based and two kinds of solvent-borne type.Because although the water paint feature of environmental protection is preferable, metal dust is in water
With it is unstable in air, often occur chemical reaction and go bad, therefore its surface need progress specially treated, cause to be used for water paint
In metal powder it is expensive, using being restricted, current metallic paint is mainly based on solvent-borne type, according to paint base resin not
Together, solvent-borne type metallic paint includes metal acrylate paint, fluorine carbon metal paint etc..The most important application field of metallic paint is garage
Industry.The outer surface of automobile of metallic paint is coated, the metal plate part surface that can not only allow after application seems more glittering moving, and
And under a different angle, due to the refraction of light, car color, even profile can be allowed all to be varied from.Allow vehicle appearance and modeling
Seem more rich, more interesting, this is why " metallic paint " understands one of more and more universal reason.With coating and application water
Flat progress, effect of the people to commercial car coating have new knowledge, progressively recognize coating selection and construction quality to business
Have very big meaning with the use of car from now on, can reduce maintenance cycle and expense, whole service life etc. have it is critically important
Meaning.Modern coatings are developed so far the history of last 100 yearses, with the maximization of commercial car and the continuous deterioration of working environment,
To the quality requirements more and more higher of coating, the main function of coating is anti-corrosion, antifouling etc., the existing commercial car coating process life-span
Short, the quality retention time is short, clagging ability, easily cracks.
【The content of the invention】
The purpose of the present invention is exactly to solve the problems of the prior art, proposes a kind of special long-life strong adhesive force of commercial car
Coating process, the coating life-span on commercial car surface can be made longer, avoid the cracking of commercial car surface lacquer painting, coating process is simple
Effect is good, can improve operating efficiency, reduces cost, improves quality, improves enterprise competitiveness, can extend commercial car surface
The glossiness retention time of lacquer painting.
To achieve the above object, the present invention proposes a kind of special long-life strong adhesive force coating process of commercial car, including
