Abstract

Disclosed is a two-component isocyanate coating. The coating comprises an A component and B component. The coating comprises following raw materials in parts by weight: 30 parts of hydroxyl acrylic resin, 25 parts of polyacrylate aqueous dispersoid, 7 parts of water-based polyaniline emulsions, 15 parts of inorganic pigments, 15 parts of fillers, 10 parts of graphite-phase carbon nitride, 1.5 parts of defoaming agents, 6 parts of coalescing agents, 2 parts of neutralizers, 2 parts of a dispersing agent, 4 parts of a thickening agents, 12 parts of distilled water and 3 parts of wetting agents;1.5 parts of leveling agent, 1 part of antirust agent, 0.8 part of guaiacol and 2 parts of cellulose; the component B is a water-based isocyanate curing agent, graphite-phase carbon nitride is added in the preparation process of the coating, the self-cleaning performance of a coating film can be effectively improved, the combination of cellulose and the curing agent is beneficial to accelerating the drying of the coating and guaranteeing the mechanical performance of the coating film, the formula of the coating is reasonable, and the sprayed coating film can be quickly leveled; the excellent leveling and smoothing effects are achieved, and the coating film is high in hardness, high in scratch resistance and high in pollution resistance.

Description

technical field [0001] The invention relates to a two-component isocyanate coating, specifically in the technical field of coating preparation. Background technique [0002] With the advancement of science and technology and the rapid development of the national economy, people's awareness of environmental protection is increasing day by day, and their pursuit of health is getting higher and higher. Environmental protection and energy saving have become the main issues facing the global coatings industry. [0003] Two-component isocyanate coatings are widely used as metal protection and wood furniture due to their superior performance. However, with the development of society, other performance requirements for coatings are also getting higher and higher. Cleaning function, and the anti-corrosion and anti-rust performance is also poor, the hardness is low, and the scratch resistance is poor. [0004] Therefore it is very necessary to study a kind of environmental protection...
