Description

一种高扯断伸长率的橡胶
技术领域
本发明主要涉及注塑产品生产成型领域，尤其涉及一种高扯断伸长率的橡胶。
背景技术
为了满足零部件的性能要求，例如铁道混凝土轨枕下用橡胶垫板，要求天然混炼胶的硬度范围为72-82，扯断伸长率要求大于250%。该橡胶的硬度比较低，扯断伸长率要求比较高。
发明内容
本发明提供一种高扯断伸长率的橡胶，该橡胶具有硬度低于80，并且扯断伸长率要求大于350%，为了达到上述目的，本发明采用以下技术方案：本发明配方为：NR，100份；炭黑N990，10-30份；古马隆树脂，5-10份；氧化锌，5份；硬脂酸，1.5份；硫磺，1.5份；促进剂CZ，2.5份；防老剂4010NA，2份；白炭黑，0-8份。
优选的，所述炭黑N990，20份。
优选的，所述古马隆树脂，8份。
优选的，所述炭黑N990，20份；所述古马隆树脂，8份。
本发明的有益效果：本发明提供的橡胶配方生产的橡胶，具有硬度低于80，并且扯断伸长率要求大于350%，满足扯断伸长率要求比较高的橡胶需求。
具体实施方式
本发明配方为：NR，100份；炭黑N990，10-30份；古马隆树脂，5-10份；氧化锌，5份；硬脂酸，1.5份；硫磺，1.5份；促进剂CZ，2.5份；防老剂4010NA，2份；白炭黑，0-8份。
实施案例一：
一种高扯断伸长率的橡胶，其配方为：NR，100份；炭黑N990，10份、20份、30份；氧化锌，5份；硬脂酸，1.5份；硫磺，1.5份；促进剂CZ，2.5份；防老剂4010NA，2份；白炭黑，0-8份。
根据上述橡胶配方，对橡胶的硬度和扯断伸长率进行实验检测，得到炭黑N990对橡胶的硬度和扯断伸长率的影响，如表1所示，
表1为炭黑N990对橡胶的硬度和扯断伸长率的影响：
通过表1可以看出，随着炭黑用量的增加，橡胶的硬度不断增大,扯断伸长率不断减小。
实施案例二：一种高扯断伸长率的橡胶，其配方为：NR，100份；炭黑N990，20份；古马隆树脂，5份、8份、10份；氧化锌，5份；硬脂酸，1.5份；硫磺，1.5份；促进剂CZ，2.5份；防老剂4010NA，2份；白炭黑，0-8份。
根据上述橡胶配方，对橡胶的硬度和扯断伸长率进行实验检测，得到古马隆树脂对橡胶的硬度和扯断伸长率的影响，如表2所示：
通过表2可以看出，随着古马隆树脂用量的增加，橡胶的硬度不断减小,扯断伸长率不断增大。
根据上述实施案例一、二的实验结果，为了达到本发明的目的，该橡胶具有低于80的硬度，并且扯断伸长率要求大于350%，优选的，本发明的一种橡胶配方中
各组分及含量为：NR，100份；炭黑N990，20份；古马隆树脂，8份；氧化锌，5份；硬脂酸，1.5份；硫磺，1.5份；促进剂CZ，2.5份；防老剂4010NA，2份；白炭黑，0-8份。
上述实施例仅例示性说明本专利申请的原理及其功效，而非用于限制本专利申请。任何熟悉此技术的人士皆可在不违背本专利申请的精神及范畴下，对上述实施例进行修饰或改变。因此，举凡所属技术领域中具有通常知识者在未脱离本专利申请所揭示的精神与技术思想下所完成的一切等效修饰或改变，仍应由本专利请的权利要求所涵盖。
