Abstract

The invention relates to the technical field of coatings, and provides a white fluorocarbon finish to solve the problem of no stain resistance of white fluorocarbon finishes. The white fluorocarbon finish is composed of a component A and a component B, and a mass ratio of the component A to the component B is (7.5-8.5):1; the component A comprises, by mass, 75-100 parts of fluorocarbon resin, 30-40 parts of titanium dioxide, 20.4-27.2 parts of xylene, 11.4-15.2 parts of butyl acetate, 1.5-2 parts of lotus leaf powder, 3-4 parts of a silane coupling agent and 7.5-10 parts of polysiloxane, the polysiloxane is a linear polymer chain, and end groups at both ends of the polysiloxane are a hydroxyl group and hydrogen respectively; and the component B includes a curing agent. The lotus leaf powder is added, and the stain resistance of the lotus leaf powder is used to facilitate the enhancement of the stain resistance of the white fluorocarbon finish without easily affecting the decoration function of the white fluorocarbon finish.

Description

technical field [0001] The invention relates to the technical field of coatings, more specifically, it relates to a white fluorocarbon topcoat. Background technique [0002] White fluorocarbon topcoat is a two-component self-drying coating with advanced fluorocarbon resin and special resin as the main film-forming substance. Due to the high electronegativity of the introduced fluorine element and strong carbon-fluorine bond energy, fluorocarbon resin coatings have properties such as weather resistance, heat resistance, low temperature resistance and chemical resistance. White fluorocarbon topcoats have been used in construction, electrical and electronic It is widely used in various fields such as industry and machinery industry. [0003] However, the surface of the white fluorocarbon topcoat is not stain-resistant. When the surface of the white fluorocarbon topcoat is in contact with dirt, it is easy to leave stains, and the stains will be more obvious on the white topcoat...
