Abstract

A surface gloss treatment agent and a preparation method thereof, the surface gloss treatment agent is formed by mixing component A and component B; the component A includes the following raw materials: hydroxyl acrylic resin, functional matting resin, butyl acetate , propylene glycol methyl ether acetate, cyclohexanone, methyl isobutyl ketone, toluene and xylene; the B component includes raw materials: HDI trimer curing agent and butyl acetate. The surface gloss treatment agent of the present invention can form a paint film with a stable glossy surface through the mutual matching of a medium-low hydroxyl value acrylic resin and a functional matting resin, and can form glossy surfaces on different glossy surfaces after being cross-linked with a trimer curing agent. Uniform paint film; after spraying the surface treatment agent, the gloss is stable and the appearance effect is uniform. It is especially suitable for the repair of hydroxyacrylic semi-gloss paint in construction machinery, and its preparation method is simple.

Description

technical field [0001] The invention relates to a gloss treatment agent and a preparation method thereof, in particular to a surface gloss treatment agent and a preparation method thereof. Background technique [0002] The surface gloss treatment agent is a kind of agent used to deal with the color difference and gloss inconsistency between the repaired area and the unrepaired area, and the appearance effect is greatly different. The surface gloss treatment agent can make the repaired area and the unrepaired area have the same gloss and color difference. It is mainly used in the repair of engineering machinery hydroxyacrylic semi-gloss paint. [0003] After the existing surface gloss treatment agent is repaired at the rivet, the problems of blooming and whitening are prone to occur. [0004] CN101469247A discloses a two-component polyurethane coating composition, with a group A acrylic resin with a branched chain carbon number less than 6 and a B component polyisocyanate a...
