Description
技术领域
本发明涉及一种无线电装置用橡皮电缆环保抗菌护套组合物。
背景技术
电缆护套广泛应用于通讯设备、仪表仪器、以及运载工具上的配电设备中，由于环境因素及工作条件的影响，要求电缆护套除具有绝缘等基本性能外，为了适应不同应用，还要求电缆护套具有拉力性能、硬度、抗老化、弹性以及抗菌、屈挠老化防护等各个方面的优良特性，但是随着科技的发展，电缆护套已经不能满足相关设备的需要，尤其设计航空航天等极端环境条件下，现在的电缆护套配方制备的电缆护套已经很难适应此类工作环境，尤其现有的电缆护套不具备抗臭氧氧化的性能。并且传统的电缆护套的生产涉及到橡胶的生产工艺，传统橡胶硫化工艺复杂，产品大量含可能导致严重环境污染的硫、汞或铅等有毒化合物，特别是长期接触含硫量高的橡胶制品，不仅危害人体健康，而且报废后脱硫工艺产生大量含硫气体，污染环境，因此减少橡胶制品中有害物质的含量，有利于保护环境。现有的橡胶产品的制备中，所用的材料较为普遍，特别的是纳米活性白炭华，它是一种新型橡胶专用纳米活性补强产品，该产品具有粒径小（15～40nm），粒度分布窄，比表面积大，化学活性高等特点，同时该产品所独有的“表面效应”、“小尺寸效应”以及“量子效应”，使得同橡胶产生较好的兼容性，大量填加仍可以赋予制品优异的使用性能，同时具有细腻的手感，平整密实的外观，良好的加工工艺性能， 作为一种功能性纳米活性补强材料，可以明显改善其外观光滑程度，柔软特性，同时焦烧时间可延长30％以上，抗撕性能也得到明显提高（并用10phr白炭黑可以达到9N／mm以上），特别适用于恶劣环境下使用的电缆的外护套材料配方。
发明内容
本发明的目的在于提供了一种无线电装置用橡皮电缆环保抗菌护套组合物，它所制备的电缆护套具有优良的抗臭氧氧化、耐磨性、抗菌性、抗撕性和耐热性能。
本发明是这样来实现的，一种无线电装置用橡皮电缆环保抗菌护套组合物，其特征在于该组合物组成成分按重量份配比为：天然橡胶 766份、丁苯橡胶 679份、促进剂TMTD 18份、促进剂ZDC 1份、防老剂RD 33份、防老剂4010NA 11份、纳米氧化锌 56份、硬脂酸 89份、石蜡 54份、陶土 567份、碳酸钙694份、混气炭黑 278份、32#机油 69份、纳米白炭华 289份、橡胶防霉剂RHA-M-1 7份。
发明的技术效果是：无铅、汞等符合ROHS要求，使用防老剂RD和4010NA增加抗臭氧性，防止电缆护套使用龟裂现象；使用纳米氧化锌，产品具有极强的耐磨性、抗撕性和耐热性等机械性能；增加软化剂改善低温性能；加入RHA-M-1添加剂，具有极强的抗菌效果。
具体实施方式
TMTD和 ZDC均为促进剂，可以缩短硫化时间，较少了产品中的硫含量；防老剂RD对热和氧引起的老化防护效果极佳；防老剂4010NA是通用型优良防老剂，对臭氧、屈挠龟裂的防护性能特佳；纳米氧化锌作为硫化活性剂等功能性添加剂，提高橡胶制品的光洁性、耐磨性、机械强度和抗老化性能性能指标；减少普通氧化锌的使用量，延长使用寿命；纳米氧化锌是一种多功能性的新型无机材料，其颗粒大小约在1～100纳米；由于晶粒的细微化，其表面电子结构和晶体结构发生变化，产生了宏观物体所不具有的表面效应、体积效应、量子尺寸效应和宏观隧道效应以及高透明度、高分散性等特点；硬脂酸是天然橡胶、合成橡胶广泛应用的硫化活性剂，也用作软化剂；石蜡提高橡胶抗老化性和增加柔韧性、提高制品外观光洁性，陶土提高电缆包皮的耐热、耐磨等性能；碳酸钙在橡胶行业使用填充粉料，可提高产品的拉伸、抗张、耐热、耐老化、耐撕裂等性能；32#机油为橡胶软化油；RHA-M-1为橡胶防霉剂，对霉菌有很强的抑杀能力，能抑制和杀死黑曲霉、黄曲霉、变色曲霉、木霉、枝孢霉、桔青霉、拟青霉等绝大多数霉菌；在生产中按重量份配比为：天然橡胶 766份、丁苯橡胶 679份、促进剂TMTD 18份、促进剂ZDC 1份、防老剂RD 33份、防老剂4010NA 11份、纳米氧化锌 56份、硬脂酸 89份、石蜡 54份、陶土 567份、碳酸钙694份、混气炭黑 278份、32#机油 69份、纳米白炭华 289份、橡胶防霉剂RHA-M-1 7份；生产的橡皮电缆环保抗菌护套具有含硫量低，抗菌性、抗臭氧氧化性能好，其他各项机械性能均能满足应用需要，特别适用于温度-30℃~+50℃条件下舰船、飞船、战车上配套电器、电讯设备和仪器仪表装置的连接电缆。
对由本发明制备而成的电缆护套，各项性能进行试验测试，试验结果记录在下表1中
通过表1可以看出本发明所制备的电缆护套各项性能与现有电缆护套相比表现突出，尤其表现在抗菌效果、耐臭氧、抗张强度和断裂伸长率等，尤其能够适应于恶劣环境下使用的电缆的外护套。
