Polymer cement-based waterproof coating with a suitable amount (1-3%), when the cross-linking agent with excessive waterproof coating, due to excessive cross-linking, but to make the coating performance degradation. By emulsion can be prepared by intercalation of organic Montmorillonite modified polymer emulsion. Polymer cement waterproof coating using the emulsion prepared with excellent mechanical properties, UV aging, thermal aging resistance and water resistance. The optimum amount of montmorillonite is 3%. By grafting treatment PEG-400 nanometer SiO_2 nano SiO_2 be prepared modified polymer emulsion. Polymer cement-based waterproof coating polymer cement-based waterproof coating quality, mess in the water market, the main reason is that market liquidity is a single component of the emulsion, no standard standard polymer cement-based waterproof coating for sale, and the polymer is a large part of the category, such as acrylic, vinegar C, VAE belong to the same product, but the performance is very different. Industry, cement-based waterproof coating polymer default execution GB / T23445-2009 "polymer cement waterproof coating" standard "Ⅱ" Standard. Polymer cement-based waterproof coating quality, waterproof coatings, long long source source Weifang waterproof material Limited. Weifang City for the source of waterproof material Ltd. (www.jiuyuanfangshui.com) strong, credible, Shandong Weifang waterproof, moisture-proof materials industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the long-source waterproof material into the brilliant and you work for a better future!
