摘　　要：精准选择乳液为单一的纯丙乳液或为纯丙和苯丙的混合物,乳液Tg在-10~20℃之间,填料为碳酸钙或云母粉或两者混合物,丙烯酸树脂乳液与填料的比例合理;发泡温度控制在140℃;改性淀粉在高温烘烤时产生糊化效应,能够有效减少开裂或鼓包现象,可以得到在140℃不鼓包不开裂的新型水性阻尼涂料。A single pure acrylic emulsion or a mixture of pure acrylic and styrene-acrylic is chosen.The Tg of emulsion is between-10°C and20°C,and the filler is calcium carbonate or mica powder or a mixture of the both,the ratio of acrylic resin emulsion to filler is reasonable,the foam-ing temperature is controlled at 140°C,and the gelatinization effect of modified starch is made during the high temperature baking,which can effec-tively reduce the cracking and bulging,finally a new type of water-based damping coating without bubbling and cracking at 140°C can be obtained.
