摘要: 采用动态粘弹谱（DMA）研究热固性丙烯酸酯类核—壳结构互穿网络水性阻尼涂料的动态力学性能。结果表明：合成的体系具有良好的动态力学性能。体系互穿网络间存在相互贯穿作用。互穿作用的大小依赖于MMA（甲基丙烯酸甲酯）/BA（丙烯酸丁酯）的比例及DVB（二乙烯基苯）的用量。当MMA/BA=4/6，DVB=0.1%时，涂膜具有较好的动态力学性能，且可同时满足涂膜的基本要求。

Abstract：The article studies the dynamic mechanical behavior of water-solubilized damping coating with interpenetrating polymer networks of core-shell type of thermoset polyacrylic by the dynamic viscoelastic spectrum. The result shows: by the two-step method and by the changing of main unit ratio MMA/BA and the changing of the weight fraction of DVB, we can synthesize a series of acrylic ester soap-free hydrosol with interpenetrating polymer networks(IPN) of MMA/BA" core-shell" type. IR symbol of the interpenetrating polymer networks shows all the monomer have taken part in the polyreaction . The composition system has very good dynamic mechanical behavior. The interpenetrating function exists among the interpenetrating metworks of this system, and the interpenetrating function depends on the ratio of MMA/BA and the dosage of DVB. When MMA/BA is 4/6 and DVB is 0.1%, the coating film has good dynamic mechanical behavior, and it can also reach the essential demand of the coating film. When add HMMM into hydrosol to mix coating and heat and solidify it , the partly chemical crosslink occurs, so the coating film has good damping behavior.

Key words： water-solubilized thermoset polyacrylic dynamic mechanical behavior
