The present invention relates to silane crosslinking catalyst comprising: —75 to 85 wt.-% of an olefin acrylate interpolymer and—15 to 25 wt.-% of a hindered amine light stabilizer (HALS) having a number average molecular weight Mn of 1500 to 4000 g / mol; and—optionally up to 5 wt.-% wax, wherein the silane crosslinking catalyst is free of tin, carboxylic acid(s) and sulphonic acid(s), all weight percentages with respect to the total weight of the silane crosslinking catalyst.

The invention discloses a scraping coating type polyurea elastomer corrosion-resistant and wear-resistant material and a preparation method thereof. The scraping coating type polyurea elastomer corrosion-resistant and wear-resistant material is characterized by comprising an ingredient A and an ingredient B, wherein the ingredient A is prepolymers with NCO end groups obtained through the reaction between 30 to 40 mass percent of polyether polyol and 60 to 70 mass percent of polyisocyanates; the ingredient B is prepared from 30 to 40 mass percent polyaspartic acid ester, 60 to 70 mass percent of filling materials and a small number of auxiliary agents through high-speed dispersion grinding. In the use process, the prepared ingredient A and the prepared ingredient B are weighed according to the weight ratio of 1:4, and are then uniformly mixed; next, scraping coating construction is performed. The material has the characteristics of high mechanical intensity, corrosion resistance, wear resistance, good anti-seeping performance, aging resistance, proper reaction speed, no solvent, convenient construction and the like. The scraping coating type polyurea elastomer corrosion-resistant and wear-resistant material is particularly suitable for industrial and mining enterprise equipment and spare part anti-corrosion wear-resistant liners.
