Abstract

The invention belongs to the technical field of coatings, and provides an anti-pollution polyurethane matte clear coating as well as a preparation method and application thereof.The anti-pollution polyurethane matte clear coating is prepared from acrylic resin, polyether polyol resin, a solvent, oxidized polyethylene wax powder and an isocyanate curing agent, and the anti-pollution polyurethane matte clear coating is prepared through interaction of all the components. The flexibility of a coating film is adjusted, meanwhile, the anti-pollution performance of the coating film can be improved, and the coating can be widely applied to furniture and woodware.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an anti-pollution polyurethane matt clear coating and its preparation method and application. Background technique [0002] Since the 1990s, with the development of social economy, the furniture industry has also developed rapidly. The styles, colors and functions are diversified to meet the needs of people's daily life. The development trend of coatings, one is the direction of energy saving and environmental protection, and improving efficiency, such as increasing the solid content of coatings, reducing VOC content, better water-based coatings, and UV-curable coatings. Another direction is the functionalization of coatings, such as artistic effects such as shape and color, protective properties such as wear-resistant color retention and gloss retention, and other chemical resistance aspects closely related to use, such as acid and alkali resistance, hand sweat resistance, etc...
