摘　　要：为了有效地提高环氧树脂(EP)防腐涂料的综合性能,本研究成功制备了新型无机纳米填料改性海泡石(OMSEP),将含量为0%、1%、2%、3%、4%和5%(质量分数,下同)的OMSEP纤维首次添加到纯EP防腐涂料中,并对比分析了纯EP涂料和OMSEP/EP复合涂料的综合性能。结果表明:新型无机纳米填料OMSEP的加入能有效提高纯EP涂料的综合性能,并且当OMSEP的添加量为3%时,OMSEP/EP复合涂料的附着力为1级,耐冲击性为52 kg·cm,磨耗量仅为0.01 g,在低频区(|Z|_(0.01 Hz))的阻抗模量比纯EP涂料高三个数量级,表现出最优的力学性能和耐腐蚀性能。In order to effectively improve the comprehensive performance of epoxy resin(EP)anti-corrosive coating,a new type of inorganic nanofiller modified sepiolite(OMSEP)was successfully prepared.Then the OMSEP fibers with a content of 0%,1%,2%,3%,4%and 5%were ad-ded to the pure epoxy resin(EP)anti-corrosive coating for the first time,and the comprehensive performance of OMSEP/EP composite coating and pure EP coating were compared and analyzed.The results show that the addition of the new inorganic nanofiller OMSEP can effectively improve the overall performance of pure EP coatings,and when the amount of OMSEP added is 3%,the adhesion of OMSEP/EP coating is level 1 and the impact resistance is 52 kg·cm,the abrasion amount is only 0.01 g,the impedance modulus in the low frequency region(|Z|0.01 Hz)is three orders of magnitude higher than that of pure EP coating,showing the best mechanical properties and corrosion resistance.
