纳米填料改性橡胶电缆料的研究

Study on properties of rubber improved with nanomaterials used in cable

为了提高橡胶电缆的使用寿命 ,通过在橡胶电缆料中加入不同种类、粒径和经过不同方法进行表面处理的无机纳米粒子 ,改善了对橡胶基体机械、硫化、介电等性能。结果表明 :不同的纳米粒子及添加量对橡胶性能的影响不同。总体上看 ,纳米粒子的加入能够对橡胶起到改善强度、韧性等机械性能、缩短硫化时间等作用 ,同时不使橡胶原有的优良介电性能恶化 ,并且在某些方面还有一定的提高。

The properties of chloroprene rubber can be improved by adding nanomaterials for the special effects expressed on the nanoparticles.The mechanical,sulfuration and dielectric properties of the rubbers are studied in this paper by adding three kinds of nanoparticles(nano-Al 2 O 3 ,nano-SiO 2 and nano-ZnO).It is shown that the properties of the base rubber are changed dissimilarly according to adding different kind or content of the nanoparticles.In conclusion,the tear strength and plasticity of the rubber are increased by adding the three kinds of nanoparticles.The sulfuration property of the rubber with nano-ZnO is not the same to that of the rubbers with other two nanoparticles.The dielectric deterioration has not been found.In some content of nanoparticles,volume resistivity of the composite is improved clearly and di-electric loss reduced.
