Problems solved by technology

[0003] However, most of the organic solvents used in the existing solvent-based coatings are flammable and volatile, pollute the environment, and are harmful to the human body, especially their low flash point makes the coatings have great potential safety hazards during production, transportation and use; and During the production, construction, drying, and curing of solvent-based coatings, the volatile organic compounds (VOC) contained in them are emitted into the air in the form of gaseous molecules, which not only causes environmental pollution, but also poses a threat to human health.

Abstract

The invention provides a high-flash-point alkyd resin protective coating as well as a preparation method and an application thereof, and belongs to the technical field of coatings. The high-flash-point alkyd resin protective coating provided by the invention comprises the following components in parts by weight of 60-65 parts of alkyd resin, 15-20 parts of titanium dioxide, 5-15 parts of barium sulfate, 5-10 parts of an alcohol ether solvent, 0.3-0.4 parts of fumed silica, 0.2-0.4 parts of a wetting agent, 0.3-0.5 parts of a dispersing agent, 0.7-1 part of a drier, and 0.2-0.3 parts of an anti-skinning agent. According to the coating, alkyd resin is used as a main body, and the alcohol ether solvent, titanium dioxide, barium sulfate and fumed silica are added, and the obtained alkyd resinprotective coating has high flash point and is safer in the production, transportation and use processes under the action of the wetting agent, the dispersing agent, the drier and the anti-skinning agent; and the alkyd resin protective coating has excellent performances such as acid resistance, alkali resistance, weather resistance and the like, and is low in toxicity, green and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-flash point alkyd resin protective coating and a preparation method and application thereof. 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 flammabl...
