Abstract

The invention discloses a chrome-free fingerprint-resistant environment-friendly coating. The coating contains the following components in parts by weight: 40-50 parts of a film-forming condensation polymer, 5-8 parts of aminopropanol ascorbic acid phosphate modified graphene oxide, 15-20 parts of epoxy resin, 1-4 parts of a dispersing agent, 1-4 parts of a flatting agent, 1-4 parts of a defoamingagent and 20-40 parts of water. The invention further discloses a preparation method of the chrome-free fingerprint-resistant environment-friendly coating. The preparation method comprises the stepsof adding the film-forming condensation polymer into water, uniformly stirring, adding other components, stirring at a rotation speed of 800r / min-1300r / min for dispersion for 50-60 minutes, and filtering, so as to obtain a finished product. The chrome-free fingerprint-resistant environment-friendly coating has relatively excellent corrosion resistance, stability and alkali blackening resistance and is safe and environment-friendly in use.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a chromium-free fingerprint-resistant environmental protection coating and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the demand for stainless steel plates with good corrosion resistance and decorative properties is increasing in the fields of household appliances, kitchen and bathroom, and building materials. However, the stainless steel plate in the prior art has the problems of hand sweat and grease pollution, and the fingerprints on the surface of the smooth stainless steel plate are difficult to remove, which not only affects the appearance, but also introduces the problem of local corrosion during use, which cannot meet the use under special conditions. Require. In order to further expand its application field to meet market demand, people have put forward higher requirements for stainless steel plates, n...
