Abstract

The invention discloses a special coating for acrylic finishes, and a making method thereof. The special coat comprises a component I and a component II having a same amount with the component II, the component I is formed by a component A and a component B, the component A in the component I comprises modified epoxy resin, a flexibilizer, mica, an assistant and an anti-settling agent, the component B in the component comprises a curing agent and a coupling agent; and the component II comprises polyurethane modified acrylic resin, rutile titanium dioxide, a film forming assistant, purified water, an antifoaming agent, a dispersant, a flash rust inhibitor and a thickening agent. The special coating is obtained by preparing the component I, preparing the component II and compounding the component I with the component II. The coating has the advantages of strong adhesion, unlikely shedding, good impermeability, good corrosion resistance, strong weatherability, unlikely saponification and fast drying, and has a very good protection effect at a low temperature.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a special coating for an acrylic topcoat and a preparation method thereof, belonging to the technical field of anti-corrosion coatings. Background technique [0002] Outdoor steel structure materials include large construction machinery, bridges, public facilities, etc. It is necessary to take anti-corrosion measures for outdoor steel structure materials. Among various anti-corrosion technologies and measures, the use of coating anti-corrosion is the simplest and most effective method. There are also some paints for spraying on the surface of objects in the prior art, but the spraying effect is not very satisfactory, and there are shortcomings such as poor appearance quality, easy corrosion, wear, and poor outdoor weather resistance, thereby affecting the appearance quality and image of the object. Traditional coatings for outdoor steel structure materials are solven...
