Abstract

The invention discloses a high-hardness fingerprint-resistant coating and a preparation method thereof. The high-hardness fingerprint-resistant coating comprises the following components in percentage by weight: 10 to 30 percent of solvent, 40 to 60 percent of fluorocarbon resin, 10 to 20 percent of amino resin, 1 to 30 percent of nano granules, 5 to 10 percent of polytetrafluoroethylene, 2 to 5 percent of polyethylene wax and 1 to 2 percent of auxiliary agent, wherein the nano granules are at least one of nano silicon dioxide, nano titanium dioxide, nano zirconium dioxide and nano zinc oxide. Compared with the prior art, the high-hardness fingerprint-resistant coating does not contain metal ions with environmental pollution, has strong adhesion, and can be coated on the surface of a steel plate by adopting modes of dip coating, spray coating, roll coating and the like; and the coated steel plate has the characteristics of high hardness, fingerprint resistance, pollution resistance, high toughness, acid resistance, alkaline resistance and the like, and can be widely applied to home appliances and other living goods.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-hardness anti-fingerprint coating and a preparation method thereof. Background technique [0002] At present, with the improvement of people's quality of life, products such as automobiles, home appliances, and daily necessities are constantly updated, and higher requirements are put forward for the aesthetics and environmental protection of products. The performance of the steel plate used on the surface of the product directly affects the appearance of the product. Therefore, in view of the problem that the previous steel plate is easy to leave clear fingerprints when touched, people have researched and developed the fingerprint-resistant steel plate. The anti-fingerprint steel plate is a kind of composite coating plate obtained after anti-fingerprint treatment on the surface of the steel plate. At present, fingerprint-resistant steel plates are developing in the direc...
