Abstract

The invention relates to the technical field of paint coating processing, and discloses an alkyd resin magnetic protective paint with a high flash point. The paint comprises the following raw materials in parts by weight: 70 to 80 parts of acrylic acid modified alkyd resin, 0.4 part of a wetting dispersant AT203, 0.4 part of bentonite, 20 to 30 parts of titanium dioxide, 0.6 to 0.8 part of a composite drier, 0.1 to 0.2 part of an anti-skimming agent, and 3 to 5 parts of solvent oil. Through a two-step esterification method, a carboxyl group on an acrylic resin chain segment completely reacts with polyol ester so as to embed acrylic resin into an alkyd resin chain segment, and a good modification effect is achieved. The main raw material source of the alkyd resin magnetic protective paint is vegetable oil or fatty acid, the dependence on petroleum products is small, and the alkyd resin magnetic protective paint is cured in an air / oxygen mode, so that the resin curing cost is low. The paint has the advantages of quick drying and good outdoor weather resistance of an acrylic resin paint, overcomes the defects of low hardness and low drying speed of an alkyd resin paint, and has a great market application prospect.

Description

technical field [0001] The invention relates to the technical field of paint and coating processing, in particular to a high-flash point alkyd resin magnetic protective coating. Background technique [0002] Solvent-based coatings are highly decorative, durable, protective, and multifunctional, and are widely used in modern industry, national defense, information, biochemistry, new materials, aerospace, ocean development, renewable energy development, and environmental protection. Organic solvents in solvent-based coatings play a key role. For example, organic solvents can reduce the surface tension of coatings, improve the wetting and dispersion performance of pigments, adjust the viscosity of film-forming resins and coatings, and improve the fluidity of coatings. Coating products meet different paint making requirements and construction requirements. [0003] However, most of the organic solvents used in the existing solvent-based coatings are flammable and volatile, poll...
