| 摘 要： | 用硅烷偶联剂甲基丙烯酰氧丙基三甲氧基硅烷(MPTMS)和丙烯酸丁酯(BA)对硅土(SE)进行表面接枝改性,用傅立叶红外光谱分析了改性硅土的表面化学结构。以改性硅土与EPDM和PP等共混,采用动态硫化的方法制备了热塑性弹性体(TPE),考察了改性硅土对热塑性弹性体的力学性能和耐磨性能的影响。结果表明:添加改性硅土可使TPE的100%定伸强度、撕裂强度和耐磨性能有所提高,但是拉伸强度有所下降。

| Abstract: | Siliceous earth is modified by surface grafting polymerization of methacryloxyl-propyl trimethyl silane and butyl acrylate. The surface of the modified siliceous earth is determined by Fourier infra-red spectrum. Ethylene-propylene-diene-monome/ Polypropyle thermoplastic elastomers filled with the modified siliceous earth is prepared by dynamically vulcanized. The mechanical and abrasion properties of the filled TPE are tested. Results show that the modulus at 100 %, tear strength and abrasion ofthe TPE filled with the modified siliceous earth are improved, but tensile strength decreases. |
