Abstract

The invention belongs to the technical field of coatings and particularly discloses a quick-drying environment-friendly coating for surface treatment of mechanical equipment and a preparation method thereof. The coating is prepared from 20 to 35 parts of phenolic resin, 18 to 30 parts of furan resin, 15 to 30 parts of acrylic resin, 5 to 8 parts of a quick-drying silicon solution, 2 to 5 parts ofgraphene, 3 to 5 parts of a pigment, 1 to 1.5 parts of a binder, 1 to 1.5 parts of a defoaming agent, 2 to 3.5 parts of a coalescing agent and 0.5 to 1 part of a thickening agent. The phenolic resin,the furan resin and the acrylic resin are added, so that the coating has the characteristics of high strength, tear resistance, impact resistance, wear resistance and the like; the quick-drying silicon solution is added, so that the coating can be quickly dried and solidified; the graphene is added, so that a good physical barrier effect is achieved, and the corrosion resistance of the coating isenhanced; the prepared coating product has good corrosion resistance and impact resistance and is environmentally friendly, the drying speed of the coating is high, and the preparation method is simple and easy to implement.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a quick-drying environmentally friendly coating for surface treatment of mechanical equipment and a preparation method thereof. Background technique [0002] Paint, traditionally called paint in China. The so-called 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, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. [0003] At present, the existing coatings have a single function, cannot have good impact resistance, corrosion resistance and slow drying speed; in addition, some harmful organic antifungal agents are added to the existing coatings, which affects the physical and mental health of users . Contents of the invention [0004] The purpose of...
