摘　　要：以ELOTEX产品和新疆当地材料为基础,在不同的环境下,添加不同的聚合物胶粉和憎水性添加剂,对胶粘剂和抹面砂浆的粘结强度、系统抗冲击强度和吸水量的影响进行了试验。结果表明,在膨胀聚苯板薄抹灰外墙外保温系统的胶粘剂和抹面砂浆中添加2.7%～3.1%的VAE胶粉,可以获得优异的粘结强度和抗冲击强度;添加0.25%～0.3%ELOTEX憎水剂SEAL80可获得良好的耐水粘结强度和抗冻融强度,并使系统获得满足JG149—2003标准要求的低吸水量(≤500g/m2)。对聚合物改性砂浆作用机理进行分析,给出在新疆地区聚合物使用的方法。Based on Elotex produets and local raw materials in Xinjiang region influence of adding different polymer powder and hydrophobic agent under different environment on the adhesive strength of float work mortar and adhesive mortar as well as on the impact resistance and water absorption of external insulation system are tested. The result proved that by adding 2.7%-3.1% VAE polymer powder in float work mortar and adhesive mortar of expanded polystyrene EIFS,excellent adhesive strength and impact resistance can be achieved. By adding 0.25%-0.3% Elotex hydrophobic agent SEAL80,good wet adhesive strength and freeze/thaw strength as well as low water absorption（≤500 g/m^2）which is required by standard JG 149--2003 can also be achieved. The mechanism of polymer modified mortar is analyzed and the usage of polymer in Xinjiang region is given.
