甲基丙烯酸铈的制备及其补强天然橡胶性能研究

制备甲基丙烯酸铈[Ce（MAA）₃]，并对其补强天然橡胶（NR）性能进行研究。结果表明：Ce（MAA）₃的粒径为20 μm左右；硫化后，胶料中Ce（MAA）₃的粒径明显减小，分散效果较好，与橡胶的相界面作用增强；在一定范围内，随着Ce（MAA）₃用量增大，Ce（MAA）₃补强NR硫化胶的拉伸强度和撕裂强度增大，Ce（MAA）₃用量为40份时，其补强效果较好。;In this study，cerium methacrylate[Ce（MAA）₃] was prepared，and the properties of Ce（MAA）₃ reinforced NR were investigated.The results showed that，the particle size of Ce（MAA）₃ was about 20 μm and it decreased significantly after curing. The dispersion of Ce（MAA）₃ and interface interaction with the rubber phase were also improved after curing.With the addition level of Ce（MAA）₃ increasing，within a certain range，the tensile strength and tear strength of Ce（MAA）₃ reinforced NR increased.When the addition level of Ce（MAA）₃ was 40 phr，the reinforcement effect was better
