Abstract

The present invention aims to solve the harm to the environment caused by the existing chromium-containing anti-fingerprint coatings in the process of preparation, storage, transportation and use, especially the pollution caused by chromium to the environment. The chemical components involved in the present invention are: water-based polyurethane resin 40~70wt%, silica sol 4~8wt%, water-based polytetrafluoroethylene wax paste 10~20wt%, deionized water 20~40wt%, EFTOP EF-112 0.2~0.3wt%, ethylene glycol 2~3wt% %, Asekahate B-1019 0.5~0.7wt%, put water-based polyurethane resin into the reaction kettle, add silicon dioxide, water-based PTFE wax slurry while stirring, then add film-forming aids, and then put into the reaction kettle For other additives, add deionized water into the reaction kettle at last, and continue to stir for 15 to 30 minutes to obtain the product chrome-free anti-fingerprint coating.

Description

technical field [0001] The invention relates to a coating composition, in particular to an anti-fingerprint coating for manufacturing anti-fingerprint steel plates. Background technique [0002] At present, as people's requirements for quality of life are getting higher and higher, not only are the daily necessities used beautiful, but they are also required to be environmentally friendly and harmless. With the continuous update of automobiles, home appliances, office supplies, etc., the requirements for steel plates are getting higher and higher. Fingerprint-resistant steel plates are an upgraded product and high value-added surface treatment product. Compared with ordinary bare steel plates, it is not only The corrosion resistance of the steel plate is improved, and there are many new properties such as fingerprint resistance, coating and electrical conductivity. In the existing technology, the anti-fingerprint steel plate treatment is to passivate the substrate wire and ...
