Abstract

The invention provides an aerosol type coating spray and a preparation method thereof. The formula of the coating spray comprises the following components in parts by weight: 10.0 to 30.0 parts of an environment-friendly cosolvent, 40.0 to 65.0 parts of water-based modified resin, 5.0 to 30.0 parts of water, 0.1 to 3.0 parts of a surfactant and 0.1 to 3.0 parts of an auxiliary agent. The coating agent has the following beneficial effects that 1, a binary aerosol packaging mode is adopted, flammable and explosive gas and water-based products are not contained, combustion is avoided, the volatilization speed is moderate, and the environment-friendly requirement is met; 2, the construction operation is flexible, simple and convenient, and the storage stability is good; 3, a single-component self-drying product is cured at normal temperature and does not need to be baked; and 4, the coated coating is high in glossiness, high in hardness, wear-resistant, and good in hydrophobic, oil-repellent and anti-fouling properties. The invention further discloses a preparation method of the coating spray.

Description

technical field [0001] The invention relates to the technical field of aerosol coating agents, in particular to an aerosol type coating spray and a preparation method thereof. Background technique [0002] Coating technology is an important part of surface decoration engineering technology. With the rapid development of the national economy and the improvement of people's material and cultural living standards, people have put forward higher and higher requirements for the appearance of objects and the effect of use. The emergence of coating technology has met this demand with extremely high cost performance, and the coating industry has shown a good momentum of vigorous development. Coating technology has been widely used in various materials including metal materials and non-metal materials, especially plastic and glass. Plastic has the advantages of light weight, excellent performance, easy processing and molding, etc., but there are also some disadvantages, such as low...
