Coating and self-spraying paint

Abstract

The invention relates to a coating and a self-spraying paint. The coating comprises a film-forming substance, an antirust filler, a pigment, an auxiliary agent and a solvent, wherein the film-formingsubstance is polysulfide thermoplastic acrylic resin, and the structural formula of the polysulfide thermoplastic acrylic resin comprises a sulfydryl functional group. The sulfydryl functional group can endow the thermoplastic acrylic resin with good flexibility, solvent resistance, stress relaxation and other properties, and can obviously enhance the oil resistance of a paint film formed by the coating and the adhesive force on aluminum, zinc and other inorganic matrixes. Therefore, the coating and the self-spraying paint comprising the paint can be suitable for spraying of equipment making contact with gasoline or organic solvents, such as automobiles and motorcycles, and can also be suitable for spraying of aircrafts with high requirements for paint film performances, such as aircrafts,and realizes rapid repairing of paint films of aircrafts such as airplanes.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to coatings and self-spraying paints. Background technique [0002] Although traditional thermoplastic acrylic resin coatings dry quickly at room temperature and are easy to use, and the formed traditional paint film has good gloss and color retention properties, the traditional paint film has poor gasoline resistance, making traditional thermoplastic acrylic resin coatings unsuitable. It is suitable for the spraying of equipment exposed to gasoline or organic solvents, such as automobiles and motorcycles, and it is not suitable for the spraying of aircrafts that require higher paint film performance, such as airplanes. [0003] At the same time, due to the low surface energy of the substrates such as aluminum and zinc, the adhesion of traditional paint films on the substrates of zinc, aluminum and their alloys is low.

Problems solved by technology

[0002] Although traditional thermoplastic acrylic resin coatings dry quickly at room temperature and are easy to use, and the formed traditional paint film has good gloss and color retention properties, the traditional paint film has poor gasoline resistance, making traditional thermoplastic acrylic resin coatings unsuitable. It is suitable for the spraying of equipment exposed to gasoline or organic solvents, such as automobiles, motorcycles, etc., and it is not suitable for the spraying of aircrafts that require higher paint film performance, such as airplanes, etc.

[0003] At the same time, due to the low surface energy of the substrates such as aluminum and zinc, the adhesion of traditional paint films on the substrates of zinc, aluminum and their alloys is low.

When it is necessary to spray traditional thermoplastic acrylic resin coatings on aluminum, zinc, etc. Complex and cumbersome, labor-intensive, and the cost of various raw materials is relatively high
