Description
技术领域
本发明涉及再生胶生产技术领域，具体涉及一种高强力再生胶及其制备方法。
背景技术
橡胶因其具有很好的弹性、可塑性、耐磨性等特点，广泛应用于工业、国防等领域，长期成为国家重要的战略物资，在国民经济和社会发展中占有重要地位。我国是橡胶消费大国，消费量占世界总量的28％，但橡胶资源仅占世界的12.2％，每年80％以上的天然橡胶、46％的合成胶依赖进口，连续5年低于国际安全线30％以下，成为继石油之后的第四大紧缺性战略物资。同时，我国又是一个废旧橡胶产生量最大的国家，随着我国汽车工业的发展和汽车保有量的增加，废旧轮胎增速高于6％。因此，我国橡胶工业在大力开发合成橡胶新品种、提高合成橡胶总产量的同时，各地企业不断注重废轮胎的回收利用。其中废轮胎生产再生胶，是弥补我国橡胶资源短缺的有效途径之一。
再生胶是以废旧橡胶制品为原料，经过粉碎、脱硫和精炼工艺过程，生产得到的具有一定可塑度，能重新使用的橡胶材料。所谓“脱硫”，是把废旧橡胶经过化学的与物理的加工处理后，使弹性硫化胶发生部分降解，分子的网状结构受到破坏，降低其弹性而恢复其可塑性和流动性的过程，但是普遍存在能耗高，生产过程中气味重，严重危害工人健康，环保压力大等问题。
发明内容
本发明针对现有技术的不足，提供了一种机械性能好的高强力再生胶。
本发明还提供了该高强力再生胶的制备方法。

本发明的连续动态环保脱硫罐为连续动态高温常压脱硫，无废水、废气排放，低压运行，安全可靠。
3)出料后所得胶料依次经过开炼机和精炼机精炼，自动卷片称重切片，冷却储存。
所述开炼机辊筒的辊距离为0.3-0.5mm，辊温为50-60℃；所述精炼机的辊距离为0.2-0.3mm，辊温在40-50℃。
本发明的有益效果：本发明制备的再生胶抗拉强度和拉断伸长率好，气味小，再生胶的密度、灰分等物理性能均能达到杂胶再生橡胶的标准要求，毒性远远低于标准要求的数值范围，使再生胶性能提高，可用于生产民用制品，属于无味再生胶范畴，具有显著的经济和社会效益。

从表1中可以看出，实施例1-3制备的再生胶的各项性能均达到《GB/T13460～2008再生橡胶》中的TA1类标准的要求，对环境及人体都无害。
对比例中没有添加乙烯基双硬脂酰胺和乙二醇乙醚醋酸酯，制备的再生胶的抗拉强度和拉断伸长率不符合《GB/T13460～2008再生橡胶》中的TA1类标准。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
