Abstract (en)

The present invention provides a composition containing trivalent chromium compound, silica sol, organic carboxylic acid, and water, and having pH of 4-7. The present invention further provides a galvanized self-lubricating metal material comprising a galvanized metal substrate and a self-lubricating coat on the galvanized metal substrate, wherein the self-lubricating coat is produced by curing a self-lubricating composition which is the composition according to the present invention. As the self-lubricating coat is formed by curing the composition containing silica sol in the present invention, the galvanized self-lubricating metal material in the present invention not only has very high lubricating performance and corrosion resistance, but also dramatically lowers requirement for galvanized metal substrate, and allows use of hot dipped galvanized plate with high surface roughness fluctuation and low cost as substrate. Therefore, the inventive product has improved market competitiveness and economic benefits, and represents development trend of self-lubricating plate.
