Abstract

The invention discloses a film forming agent for coatings. The film forming agent is prepared from the following substances of styrene resin, isooctyl acrylate, C9 petroleum resin, urea-formaldehyde resin, methyl cellulose, triethyl borate, ethylene glycol dimethacrylate and seaweed gel. The film forming agent disclosed by the invention has the beneficial effects that the spreadability, the smoothness and the adhesiveness are good, and the protective effect and the service life of the coating are effectively improved, so that the film forming agent has extremely high promotion and use values.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a coating film-forming agent. Background technique [0002] In modern society, in order to make full use of petrochemical by-products and residual liquid of liquefied petroleum gas, the residual liquid is generally used as raw material to make the residual liquid into gas. In the gas production process, the raw material liquid needs to be gasified. Then liquid gasification tank equipment will be used, and the tank body of the liquid gasification tank is usually made of steel. In order to improve its surface quality in the atmospheric environment, it needs to be treated with anticorrosion. It is common to apply a layer of anti-corrosion coating on its surface, and the effect of anti-corrosion treatment is closely related to the quality of anti-corrosion coating. Coating film former is the matrix substance in anti-corrosion coatings, which determines the quality of coatings to...
