摘　　要：对3种聚合物胶粉改性XPS板外墙外保温体系中水泥砂浆的粘结强度进行了试验研究.试验结果表明:在满足标准规定的粘结强度要求下,纯丙烯酸基胶粉501掺量≥1.9%(以砂浆质量计),瓦克5044N胶粉掺量≥2.9%,国内EVA胶粉A掺量≥3.1%.结果表明纯丙烯酸基胶粉是XPS保温板的粘结砂浆中优良的聚合物胶粉.The test research on the adhesion sproperties of bonding mortar modified three types of polymer latex powder in XPS plate used for the outer insulation system of external wall was made.The results showed that the admixing content of pure acrylic copolymer latex powder and Wake 5044N latex powder and latex powder made in China（belonging to EVA） respectively was or surpassed 19% and 29% and 31%（based on mortar mass）.The conclusion was that pure acrylic copolymer latex powder would be excellent polymer latex powder in XPS plate used for the outer insulation system of external wall.
