Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the embodiments, so that those skilled in the art can implement it with reference to the description.

[0031] It should be understood that terms such as "having", "comprising" and "including" used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0032] The invention provides an electrostatic paint that can be sprayed into a thick film. The electrostatic paint is prepared by mixing component A and component B in a weight ratio of 3 to 5:10, and adding a diluent to adjust to a certain viscosity. and the electrostatic coating can be sprayed on the surface of the object to be coated into a certain thickness of coating film;

[0033] Wherein, the A component is composed of the first resin and an ester solvent or a ketone solvent; the B component includes the second resin, aromatic hydrocarbons, various color pigments, extender pigments a...

Abstract

The invention discloses an electrostatic coating which can be sprayed to form a thick film. The electrostatic coating is prepared by mixing a component A and a component B according to the weight ratio of 3-5 to 10, adding a diluent and performing blending to reach certain spraying viscosity, wherein the component A is prepared from first resin and an ester solvent or a ketone solvent, the component B is prepared from second resin, aromatic hydrocarbon, various colors of pigments, an extender pigment and multiple additives, and the diluent is prepared from hydrocarbon, ester and ketone solvents and an ES-80 electrostatic additive. The invention further discloses a construction method of the electrostatic coating which can be sprayed to form the thick film. The electrostatic coating is sprayed to the surface of a coated object by using a robot. The electrostatic coating can be blended to have multiple colors, has the advantages of being high in solid content, low in viscosity and small in smell, one-time coating thickness can be up to more than 40 microns during coating by using the robot, the utilization rate of the electrostatic coating is improved, the labor intensity is reduced, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of coatings, more specifically, the invention relates to an electrostatic coating that can be sprayed into a thick film and a construction method for spraying the electrostatic coating by using a robot. Background technique [0002] Electrostatic coatings are used for decoration and protection of light metal, steel surfaces, plastic surfaces, and solvent-resistant surfaces such as aircraft, trains, automobiles, ships, bridges, iron towers, outdoor electrical equipment, public facilities, and sculptures. Existing electrostatic paints have a relatively strong smell, a sprayed paint film thickness (dry film) is small, and the paint film is not plump, has poor adhesion, and does not have three-proof performance, which seriously limits the scope of application of electrostatic paints. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems and t...
