摘　　要：以丙烯酸酯聚合物的乳液为成膜物,三聚氰胺(MEL)、季戊四醇(PER)和多聚磷酸铵(APP)为膨胀阻燃体系,加入空心聚合物微球,制备了具有保温隔热功能的膨胀型建筑物用防火涂料,对其隔热性能、防火性能以及涂层的物理力学性能进行研究。结果表明:空心聚合物微球与聚合物成膜物具有良好的相容性,结合牢固,其涂层的附着力和柔韧性均明显优于空心玻璃微球。添加空心聚合物微球后,涂层的热传递能力显著下降,耐燃时间有所提高,但对炭化层的厚度以及致密性无明显影响。The insulation flame-retardant coating was prepared with Acrylate polymer emulsion as film forming matter,Mela-mine（MEL）,Pentaerythritol（PER）and Ammonium Polyphosphate（APP）as flame retardant expansion system,and the hollow polymer microspheres was used as filler to form the expansion flame retardant system for buildings.The performance of heat insulation,flame prevention and physical and mechanical properties of the coating was studied.The results showed that：good compatibility was found between the hollow polymer microspheres and the film forming matters as well as better adhesion and flexibility of coating were discovered compared with those including hollow glass microspheres;by adding the hollow polymer microspheres,the heat transfer ability decreased and flame resistance time improved with no obvious changes of thickness and compactness of char layer.
