Abstract

The invention discloses a scratch-resistant piano black coating and a preparation method thereof. The scratch-resistant piano black coating comprises the following raw materials in percentages by mass: 60 to 65% of acrylic resin, 15 to 20% of OH-based hydroxy acrylic resin, 1 to 2% of a scratch-resistant agent and 10 to 12% of a nanometer color paste, with the balance being ketone and ester solvents. The coating prepared by adopting a formula and a method provided by the invention is applied to coating of automobile parts; and after the automobile parts are coated with the coating provided bythe invention, scratch resistance is greatly improved under the premise of guaranteeing excellent adhesion force, and the gloss is better, belongs to high bright black, and meets the need of use; meanwhile, by adoption of the ketone and ester solvents, VOC emission can be effectively reduced and is extremely low, and the standards of environmental protection are completely met.

Description

technical field [0001] The invention relates to the technology in the field of coatings, in particular to an anti-scratch piano black coating and a preparation method thereof. Background technique [0002] Coatings are chemical products widely used in the fields of architectural coating, industrial metal, agricultural and construction equipment coating. Synthetic resin is one of the earliest, largest and most widely used coatings. It has the characteristics of good weather resistance, high adhesion, bright paint film, and convenient construction. Due to the diversity of synthetic resins, a variety of self-drying or drying enamel paints, primers, topcoats, and varnishes are produced. These synthetic resins with different properties are widely used in bridges and other buildings, as well as in the coating fields of machinery, vehicles, ships, and instruments. achieve universal application. Synthetic resin coatings have a wide range of uses. The coatings currently used on ...
