Problems solved by technology

With the development of technology, there are also new types of coatings such as environmentally friendly coatings on the market. During the use of these coatings, it will be found that when the coating is applied, a coating film is formed, but because it contains more water, the coating film There will be whitening phenomenon, that is, the color of the coating film is lighter than the original and the coating film is white mist, and the unsealed coating is prone to freezing in winter, which will affect the subsequent use

Abstract

The invention relates to the technical field of coating preparation, in particular to negative oxygen ion environment-friendly coating and a preparation method thereof. The coating is prepared from, by mass, 25-30 parts of polyester, 48-52 parts of polyether, 35-45 parts of tourmaline, 3-7 parts of modified silane coupling agent, 3-7 parts of stearamide, 1.5-3 parts of soybean lecithin, 5-7 parts of high alcohol, 15-25 parts of kaolin, 5-15 parts of calcium carbonate, 15-23 parts of titanium dioxide and 8-15 parts of methyl cellulose. The preparation method comprises the following steps: S1, weighing the raw materials according to the weight for later use; and S2, adding polyether and polyester into a reaction kettle, conducting heating, reducing pressure, performing vacuum dehydration for 20-40 minutes, removing vacuum, conducting cooling, adding 1,6-hexamethylene diisocyanate, conducting stirring for 2-4 hours, adding tourmaline, and continuously conducting stirring for 20-40 minutes to obtain a solution A. The water content in the coating can be reduced, the whitening condition of a coating film is relieved, and the anti-freezing performance of the coating can be improved.

Description

technical field [0001] The invention relates to the technical field of paint preparation, in particular to a negative oxygen ion environment-friendly paint and a preparation method thereof. Background technique [0002] Paint refers to a continuous film that is coated on the surface of an object to be protected or decorated and can form a firm adhesion with the object to be coated. It is usually based on resin, oil, or emulsion, with or without adding pigments and fillers. The corresponding additives are viscous liquids prepared with organic solvents or water. With the development of technology, there are also new types of coatings such as environmentally friendly coatings on the market. During the use of these coatings, it will be found that when the coating is applied, a coating film is formed, but because it contains more water, the coating film There will be a whitening phenomenon, that is, the color of the coating film is paler than the original and the coating film is...
