摘　　要：为降低聚苯颗粒保温砂浆成本,以乳化沥青替代可再分散乳胶粉制备了乳化沥青聚苯颗粒保温砂浆,并对比研究了乳化沥青和可再分散乳胶粉对聚苯颗粒保温砂浆性能的影响。结果表明,乳化沥青聚苯颗粒保温砂浆的力学性能如抗压强度和压剪粘结强度略低于胶粉聚苯颗粒保温砂浆,而线性收缩率和耐水性(软化系数和吸水率)却好于后者。In order to reduce the cost of polystyrene grain thermal insulation mortars,the polystyrene grain thermal insulation mortars were prepared by using cheap asphalt emulsion to replace redispersible polymer powder,and the effects of the asphalt emulsion on the properties of the thermal insulation mortars were investigated by comparing with the effects of the redispersible polymer powder.The test results indicate that the mechanical properties（compressive strength and adhesion strength） of asphalt emulsion-polystyrene grain thermal insulation mortars are slightly lower than that of redispersible polymer powder-polystyrene grain thermal insulation mortars,but the linear shrinkage and water resistance（water absorption and softening coefficient） of the former are better than that of the latter.
