Description

一种行车电缆绝缘用橡胶组合物
技术领域
本发明涉及起重机电缆，尤其涉及行车电缆用橡胶组合物。
背景技术
传统配方生产的橡胶，耐油性差、耐臭氧性差、耐候性差，使橡胶在户外、臭氧环境中极易老化，尤其是在低温、高温环境中，橡胶的老化会加速，致使电缆的使用寿命缩短。
发明内容
本发明旨在解决上述缺陷，提供一种行车电缆绝缘用橡胶组合物。本发明节省了成本，简化了工艺，提高了生产效率，满足了客户的使用要求。
为解决上述问题，本发明一种行车电缆绝缘用橡胶组合物，它包括下列重量份数的：
EPDM                                        100份
醋酸乙烯脂橡胶，VA含量60%，               10～20份， 
纳米氧化锌                                 6～12份
工业硬脂酸                                 1～4 份
抗水解剂P-50                               1～2.5份
硅烷偶联剂A-172                            1～1.75份
硅烷改性煅烧陶土                           100～160份
过氧化物硫化剂DCP                          3.5～4.0份
石蜡油2280                                 5.0～6.0份；
将上EPDM和醋酸乙烯酯橡胶混合开练后，投入密炼机并加入其它组分经密炼后经开炼、滤胶后轧片切片即得到所述行车电缆绝缘用橡胶组合物。
    所述的行车电缆绝缘用橡胶组合物，所述EPDM包括重量比1：1的EPR4770和EPR4640。
本发明以EPDM和活化ACM为基胶，在基胶的基础上加入纳米级氧化锌、工业硬脂酸、抗水解剂P-50、硅烷偶联剂A-172、硅烷改性煅烧陶土、过氧化物硫化剂，以上物质进行混炼，混炼完毕后，进行开炼，然后滤胶、压片、切片从而完全解决了上述传统橡胶缺陷。利用两种牌号的乙丙橡胶进行共混和乙烯醋酸乙酯共混，醋酸乙烯酯类橡胶具有非常优异的耐臭氧性、耐候性、电性能、从而使混合胶具有乙丙橡胶的柔软性，又兼具醋酸乙烯酯橡胶的耐臭氧性、耐候性、耐高温性、耐油性、耐水性。
具体实施方式
本发明一种行车电缆绝缘用橡胶组合物，它包括下列重量份数的：
EPDM                                        100份
醋酸乙烯脂橡胶，VA含量60%，                10～20份， 
纳米氧化锌                                 6～12份
工业硬脂酸                                 1～4 份
抗水解剂P-50                               1～2.5份
硅烷偶联剂A-172                            1～1.75份
硅烷改性煅烧陶土                           100～160份
过氧化物硫化剂DCP                          3.5～4.0份
石蜡油2280                                 5.0～6.0份；
将上EPDM和醋酸乙烯酯橡胶混合开练后，投入密炼机并加入其它组分经密炼后经开炼、滤胶后轧片切片即得到所述行车电缆绝缘用橡胶组合物。
所述的行车电缆绝缘用橡胶组合物，所述EPDM包括重量比1：1的EPR4770和EPR4640。
