Abstract

A water-based air-dry finishing coat is prepared form, by mass, water-based epoxy modified acrylic acid dispersions, dispersing agents, F5RK, ethylene glycol butyl ether, water, water-based epoxy modified acrylic acid dispersions, thickening agents, wetting agents, leveling agents and water. The water-based air-dry finishing coat has excellent adhesive force, weather resistance, impact resistance, chemical resistance, high rigidity, yellowing resistance, image distinctness, high luster and transparency and others.

Description

technical field [0001] The invention relates to the technical field of design coatings, in particular to a water-based self-drying topcoat. Background technique [0002] The rise and development of polymerization science has advanced the coating science and coating industry to a new modern coating stage. However, these synthetic resin coatings use a large amount of organic solvents in the production and coating process to adjust the viscosity, improve the construction process and construction performance, and cause a large amount of organic solvents to volatilize into the air, causing serious environmental pollution and ecological damage. The production, processing and use of coatings have become one of the main sources of industrial pollution. Therefore, the widely used solvent-based organic coatings are products that are difficult to meet environmental protection requirements, and will be replaced by new coatings that meet health, environmental protection, and safety stan...
