Abstract

The invention discloses flexible paint for plastics and a preparation method of the flexible paint. The flexible paint for the plastics comprises the following raw materials in mass percent: 60-70% of solid thermoplastic acrylic resin, 15-20% of bisphenol F liquid epoxy resin, 3-5% of a leveling agent and the balance of ketone and ester solvents. The paint prepared by adopting the formula and method of the invention is applied to the coating of plastic fittings, the flexibility is greatly improved on the premise of guaranteeing that the paint has relatively good adhesive force after the coating and solidification, the plastic fittings do not have a brittle phenomenon, the use requirements are satisfied, the ketone and ester solvents are adopted, and the VOC (volatile organic compounds) emission can be effectively reduced and is extremely low, so that the flexible paint is completely in conformity with environmental protection standards.

Description

technical field [0001] The invention relates to the technology in the field of coatings, in particular to a flexible coating used on plastics 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 ...
