Mechanical properties of polymer-modified cement-based waterproof coating and waterproof coating, water resistance, heat aging properties and UV aging properties were studied. The main conclusions are as follows: Poly gray than to have a significant impact on the structure and properties of the polymer cement-based waterproof coatings. High polymer cement ratio, the polymer constitutes the continuous phase, cement and other particulate dispersed in a polymer in the coating film having excellent elongation and low temperature flexibility; when oligomeric cement ratio, the formation of a rigid cement hydration topical gel network, the coating film elongation and low temperature flexibility are significantly reduced, but a coating film can improve water resistance and heat aging UV aging ability. Melamine formaldehyde resin crosslinking agents can significantly improve the mechanical properties, heat resistance and water resistance of polymer cement-based paint. Polymer cement-based waterproof coating for another reason, JS polymer cement-based waterproof coating polymer cement-based waterproof coating quality one-component, not the standard in the detection time, quality inspection institutions need to provide producers with powder polymer cement-based waterproof coating for sale, and distribution of powder specifically, can reduce the amount of cement to increase the amount of acrylic powder, relatively poor JS polymer cement also through GB, so national standards becomes very subtle. A friend lamented, with a sample of polymer cement-based waterproof coating pictures, censorship ten times, there are six or seven times, but off, in fact, when the inspection inspection agency is also very delicate. Polymer cement-based waterproof coating quality | long source (certified) | waterproof coating provides long-source by Weifang waterproof material Limited. Weifang City for the source of waterproof material Ltd. (www.jiuyuanfangshui.com) Shandong Weifang, waterproof, moisture-proof materials, leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the long leading source of waterproof material with the staff warmly welcome all inquiries negotiations to create long waterproof material source a better future.
