Problems solved by technology

PVDF fluorocarbon coating, as the "king of coatings", has been favored by the market because of its excellent weather resistance, but the fluorocarbon coating has low hardness, dull luster, easy to be polluted, poor cleaning performance, and easy to be scratched. Reduce the performance of fluorocarbon paint coating; especially in the lower floors of buildings decorated with fluorocarbon coating panels or hall passages, where there is a large flow of people, the coating is easy to be touched and easily damaged and dirty

Abstract

The invention provides anti-fouling and rubbing-resisting fluorocarbon nano-varnish. The anti-fouling and rubbing-resisting fluorocarbon nano-varnish is prepared from 30-60 parts by weight of fluorocarbon resin, 30-60 parts by weight of fluorosilicon resin, 10-20 parts by weight of amino resin, 0-5 parts by weight of an auxiliary and 2-10 parts by weight of a solvent. The anti-fouling and rubbing-resisting fluorocarbon nano-varnish has excellent gloss and hardness, has superb effect in fouling resistance and graffiti prevention, especially has excellent rubbing resistance, can meet requirements of areas having higher demands for rubbing resistance, also has better compatibility, can be applied to a conventional PVDF fluorocarbon coating and has excellent interlayer adhesion force with theconventional PVDF fluorocarbon coating, use range of the fluorocarbon varnish is expanded, after baking and curing, not only are weather resistance and other conventional properties of the original fluorocarbon coating not sacrificed, but also the original coating is further endowed with excellent gloss and hardness. The invention further provides a preparation method and an application of the anti-fouling and rubbing-resisting fluorocarbon nano-varnish.

Description

technical field [0001] The invention relates to the technical field of fluorocarbon varnishes, in particular to a fluorocarbon nanometer anti-fouling and abrasion-resistant varnish and its preparation method and application. Background technique [0002] With the development of social science and technology, coating products show a high-performance development trend. PVDF fluorocarbon coating, as the "king of coatings", has been favored by the market because of its excellent weather resistance, but the coating of fluorocarbon coating has low hardness, dull gloss, easy to be polluted, poor cleaning performance, and easy to be scratched. Reduce the performance of fluorocarbon paint coating; especially in the lower floors of buildings decorated with fluorocarbon coating panels or hall passages, where there is a large flow of people, the coating is easy to be touched and easily damaged and dirty. [0003] To this end, it is necessary to develop a kind of fluorocarbon nano antif...
