Description
Technical Field
The invention relates to the field of coatings, in particular to a high-temperature-resistant recoating single-component compression process water-based finish coating and a preparation method thereof.
Background
In recent years, with the development of the automobile industry, the coating industry is also being innovated, the original solvent-based automobile coating is being changed to the water-based coating, and the traditional process (such as: 3C 2B) is also being accelerated to be changed to the novel compact process (such as: B1B2, 3C 1B)).
3C2B shown in FIG. 1 is a conventional process, wherein 2 high-temperature baking ovens are used for middle coating and varnish, 1 high-temperature baking oven is used for colored paint, and a middle coating polishing room is needed after the middle coating is baked; the 3C1B process requires 2 pre-baking furnaces and 1 high-temperature baking furnace; the B1B2 process only needs 1 pre-baking furnace and 1 high-temperature baking furnace;
it can be seen that the B1B2 process has significant advantages in energy consumption and efficiency, and is also the mainstream process at present.
However, in the production process of the B1B2 process, it is inevitable that unqualified products need to be re-sprayed, and therefore, many problems, most commonly poor adhesion, are encountered in the normal re-spraying process, because the original coating is cured after the primary coating is subjected to high-temperature baking, and the original substrate needs to be sanded to obtain good adhesion on the original coating, but this increases a process step and causes an increase in cost; therefore, it becomes very important here to adapt a high temperature rework repainted coating product.

The isoparaffin is Isopar L.
The technical principle on which the invention is based is as follows:
1) Talc powder is a hydrous magnesium silicate mineral with a composition of 3 MgO.4SiOH.20. In the lattice structure of the talcum powder, the silicon-oxygen tetrahedron is connected into a layered structure, has higher length-diameter ratio, and is easy to crack because layers attract each other by weak residual bonds; meanwhile, the thermal expansion of the talcum powder is smaller than that of the medium, so that the talcum powder can reduce the thermal expansion of the paint film and improve the flexural rigidity of the coating at high temperature, thereby avoiding solvent volatilization during high-temperature baking and the shrinkage ratio of the paint film during paint film crosslinking, and further improving the adhesive force of the high-temperature resistant coating at high temperature.
2) The acidic phosphate auxiliary agent as an adhesion promoter can effectively solve the problems of adhesion, adhesion and the like of inorganic base materials such as metal, glass, ceramics, stone and the like; is mainly used for improving the adhesion with a metal substrate and the interlayer adhesion with a coating film.
3) The structure of the phosphate compound contains various organic substituent groups and phosphate radicals capable of generating acid-base reaction with metal inorganic substrates, and the organic groups can be alkyl groups, aliphatic groups and aromatic hydrocarbons, and can also be organic chain segments with hydroxyl groups and carboxylic acid groups. Different organic groups are suitable for different solvent-based or water-based products.
4) Because the activity of the phosphate radical is high, the metal substrate surface has the defects of slight rusting, peeling, bubbling and the like, a barrier can be formed through the chemical reaction of the phosphate radical and the metal surface, and the aim of improving the adhesion is fulfilled. Meanwhile, because of high activity, the paint has larger influence on a packaging container of the paint and other components in a paint formula; in amino baking paint and a two-component polyurethane system, active phosphate radical can further promote the reaction to make the paint film more completely cross-linked.
