Description
Technical Field
The invention relates to the field of automobiles, in particular to a preparation process of a paint layer of a local pre-formed film on the surface of an automobile.
Background
The automobile painting means that a layer of paint is coated on the surface of an automobile to achieve the effect of protecting the automobile. Baking paint is generally used for automobile painting. In an automobile manufacturing factory, the welding of a frame and a shell is finished, and the next procedure is paint spraying. The paint can be common paint, metal paint and pearlescent paint. The automobile paint spraying process comprises the following steps: puttying, polishing, painting, etc. The automobile painting includes: common paint; a metallic paint; pearlescent paint; varnish; and (4) matte paint.
Automotive paints generally have four basic components: film-forming substances (resins), pigments (including extender pigments), solvents and additives.
(1) The film-forming substance is the main component of the paint, and its function is to keep the pigment in a bright state, make it firm and durable, and adhere to the surface of an object, and is the substance that determines the type of paint. Generally, the resin is prepared from drying oil or semi-drying oil modified natural resin (such as rosin), artificial resin (such as malic acid anhydride resin), and synthetic resin (such as methyl methacrylate, polyurethane, polystyrene, polyvinyl chloride, etc.). It is common to adjust, improve its durability, adhesion, corrosion resistance, abrasion resistance and toughness by the addition of plasticizers and catalysts.
(2) The pigment is one of two nonvolatile substances in paint, and can endow the finish with color and durability, and simultaneously make the paint have hiding power, improve strength and adhesive force, change gloss, and improve fluidity and coating performance.
(3) The solvent is a volatile component in the paint, and the main function of the solvent is to fully dissolve the resin in the paint film so that the paint can be normally applied. The high-quality solvent can improve the coating performance and the paint film characteristic of the finish paint, enhance the luster and reduce the paint reticulate pattern, thereby reducing the polishing workload and being beneficial to more accurate color matching. In addition to the solvents already present in the paint, they also act as diluents for diluting the paint to make its viscosity suitable for the application requirements.
(4) And (3) an additive. In the last decade, paint technology has changed dramatically and the use of additives has become more and more common. Although the proportion of additives in the paint does not exceed 5%, they play a variety of important roles. The gloss-reducing agent has a curing agent capable of accelerating drying and enhancing gloss, a retarder capable of slowing drying speed and a flatting agent capable of reducing gloss, and some additives play a comprehensive role: i.e. reduced wrinkling, accelerated drying, prevention of blushing, and improved resistance to chemicals.
In the prior art, due to accidental scratch of an automobile, the automobile paint is always subjected to local accidental damage, and as for the local damage, an automobile owner cannot find the local accidental damage in time, and the following problems are easily caused when paint is not repaired in time, wherein one problem is that the local part is easy to rust, so that the difficulty is increased when the subsequent paint is repaired, and the other problem is that the part with the local damage is easy to generate secondary damage, so that the part with the damaged paint is increased.
