Spraying coating and preparation method and spraying method thereof

Abstract

The invention relates to the field of coatings, the invention discloses a spraying coating, and a preparation method and a spraying method thereof. The spraying coating is prepared from 40 to 45 partsof a waterborne epoxy resin emulsion, 5 to 10 parts of a waterborne acrylic emulsion, 0.5 to 2 parts of propylene glycol butyl ether, 0.5 to 1.5 parts of a dispersoid, 1 to 2 parts of a dispersing agent, 0.1 to 0.5 part of a leveling agent, 0.04 to 0.05 part of antifoaming agent, 20 to 25 parts of deionized water, 1 to 2 parts of a pigment and 1 to 2 parts of a filler. According to the spraying coating prepared by the invention, deionized water is used as a diluent; impurity introduction can be further avoided; the waterborne acrylic emulsion is added, the spraying coating can be matched withwaterborne epoxy resin emulsion to obtain the spraying coating which is easy to spray, good in adhesive force and toughness; spraying can be carried out more quickly and better; the propylene glycolbutyl ether is added, so that the coalescence performance of the spraying coating is improved, the toxicity of the propylene glycol butyl ether is extremely low, the environment-friendly performance of the spraying coating can be guaranteed, the dispersoid and the dispersing agent are added, stirring and dispersing can be better and faster conducted in the spraying coating preparation process, andthe more uniform spraying coating is obtained.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a spray coating, a preparation method thereof, and a spray coating method. Background technique [0002] Paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated. The formed film is generally called a paint film or a paint film or a coating. The paint is usually made of resin or oil or emulsion. The main component is to add pigments, fillers and corresponding additives according to actual production needs, and then formulated with organic solvents or water. Spray coatings are easy to produce and are suitable for industrial production. They are also widely used and common types of coatings. It has a wide range of applications and brings convenience to people's lives. It can not only increase the durability of the product, but also increase the aesthetics of the product. [0003] However, the types ...

[0003] However, the types of paint generally include oil-based paint and water-soluble paint. Oil-based paint is a type of paint with dry oil as the main film-forming substance. It is easy to produce, low in price, good in brushability, flexible in coating film, and good in protection performance. However, oil-based paints contain irritating gas odors, contain more harmful substances, are not environmentally friendly, are likely to endanger people's health, are flammable, and are not easy to store, while water-soluble paints generally use water as a diluent and do not contain harmful substances. , is harmless to human health, and is an environmentally friendly material. However, since water-soluble coatings generally use water as a diluent, the compatibility between various raw materials is poor, and it is easy to affect the leveling of the prepared coating products. , affecting the use of paint, the performance of water-soluble paint needs to be improved
