Description

一种防刺穿内胎配方
技术领域
本发明涉及内胎，特别涉及一种防刺穿内胎配方。
背景技术
轮胎是在各种车辆或机械上装配的接地滚动的圆环形弹性橡胶制品。通常安装在金属轮辋上，能支承车身，缓冲外界冲击，实现与路面的接触并保证车辆的行驶性能。轮胎常在复杂和苛刻的条件下使用，而因为环境的原因，常常会在行驶过程中遇到钉刺等情况，而内胎是用于保证压力和轮胎的稳定性的，在外胎被刺穿的情况下，我们也希望内胎尽量不会受损。现有技术中的充气内胎，在制造中主要使用橡胶的两个系列，一为天然橡胶及天然橡胶为主要混合胶系列；二为丁基橡胶及以丁基橡胶为主的混合胶系列。天然橡胶及其混合胶系列，以其强度高，具有可修补性而著称，但其气密性差，抗热变形及老化性差，价格高限制了它的广泛使用。丁基橡胶及其混合胶系列，以气密性好而著称，不可修补，因此需要其具有较好的防刺穿性，即在保证气密性的前提下能够提高硬度和韧性。
发明内容
本发明要解决的技术问题是提供一种硬度高、韧性好的防刺穿内胎配方。
为了解决上述技术问题，本发明的技术方案为：一种防刺穿内胎配方，以重量份计，由如下成分组成：丁基胶70-90份、EPDM15-25份、碳黑25-35份、白炭黑15-25份、高岭土8-12份、环保油20-24份、氧化锌5份、硬脂酸0.8份、微晶蜡1份、TMTD1.8份、硫磺1.7份。
优选的，所述碳黑采用660碳黑。
一种防刺穿内胎配方，以重量份计，优选由如下成分组成：丁基胶80份、EPDM20份、碳黑30份、白炭黑20份、高岭土10份、环保油22份、氧化锌5份、硬脂酸0.8份、微晶蜡1份、TMTD1.8份、硫磺1.7份。
采用上述技术方案，使得生产出来的内胎硬度和韧性增强，并且能够同时保证内胎的气密性。
具体实施方式
下面对本发明的具体实施方式作进一步说明。在此需要说明的是，对于这些实施方式的说明用于帮助理解本发明，但并不构成对本发明的限定。此外，下面所描述的本发明各个实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互组合。
本具体实施方式披露了一种防刺穿内胎配方，以重量份计，由如下成分组成：丁基胶70-90份、EPDM15-25份、碳黑25-35份、白炭黑15-25份、高岭土8-12份、环保油20-24份、氧化锌5份、硬脂酸0.8份、微晶蜡1份、TMTD1.8份、硫磺1.7份。所述碳黑采用660碳黑。
可行的，配方可以优选由如下成分组成：丁基胶80份、EPDM20份、碳黑30份、白炭黑20份、高岭土10份、环保油22份、氧化锌5份、硬脂酸0.8份、微晶蜡1份、TMTD1.8份、硫磺1.7份。
通过高岭土可以有效的提高内胎的硬度，而通过环保油、微晶蜡和硫磺可以在炼胶的过程反复反应增加内胎的韧性，从而能够在保证气密性的前提下，提高丁基胶内胎的硬度和韧性，从而可以提高防刺穿的性能。
以上对本发明的实施方式作了详细说明，但本发明不限于所描述的实施方式。对于本领域的技术人员而言，在不脱离本发明原理和精神的情况下，对这些实施方式进行多种变化、修改、替换和变型，仍落入本发明的保护范围内。
