Abstract

一种橡胶组合物,包含:(A)橡胶;(B)第一填料;(C)第二填料;所述第一填料采用湿法混炼制备成第一母胶;所述第二填料以粉末或第二母胶形式加入所述第一母胶中。所述橡胶组合物可用于制造轮胎,能够降低轮胎的滚动阻力,提高抗湿滑性能,改善耐磨性能。

Description

湿法混炼母炼胶并用填料或母胶的橡胶组合物及制备方法 技术领域
本发明涉及橡胶领域,特别涉及一种湿法混炼母胶并用填料或母胶的橡胶组合物及其制备方法。
背景技术
湿法混炼是在液相条件下将填料均匀分散于橡胶中从而得到填料/橡胶母胶的一种技术。与传统的干法混炼相比,湿法母胶的硫化胶料具有填料分散度高,滞后损失低等优点。目前制备湿法混炼母胶的技术包括胶乳填料共同沉淀法(CN102153792A,CN102516418A,CN102634083A);德国粉末橡胶联合股份有限公司的粉末橡胶技术(CN101182376A);美国Cabot公司的乳液/填料液相连续混炼技术(CN1280534A);怡维怡橡胶研究院有限公司的溶液/填料液相连续混炼技术(CN103113597A)。其中前三种技术均采用乳液进行湿法混炼,而怡维怡橡胶研究院采用的是橡胶溶液。但是这些湿法混炼技术只集中于单一填料母胶的制备。
利用湿法混炼母胶并用填料的方式对胶料性能进一步改进的工作有米其林在炭黑湿法母胶中加入第二填料,进一步降低其滚动阻力(CN103347932A);中策橡胶有限公司在湿法白炭黑母胶中并用炭黑,以改善矿山胎胎面胶的性能(CN102807689A)。但是该两项专利中的炭黑湿法母胶、白炭黑湿法母胶均由胶乳制得,由于胶乳成分中非胶组分多,容易吸附到填料表面,降低填料/聚合物相互作用力,导致硫化胶的耐磨性能较差。本专利所述的溶液湿法混炼在避免乳液湿法混炼缺点的基础上,通过并用第二填料,进一步对湿法混炼母胶性能进行改善。
发明内容
针对现有技术的问题,本发明的目的是提供一种湿法混炼母胶并用填料或母胶的橡胶组合物。本发明的另一个目的是提供一种湿法混炼母胶并用填料或母胶的橡胶组合物的制备方法。

(B)第一填料;
(C)第二填料;
所述第一填料采用湿法混炼制备成第一母胶;
所述第二填料以固体或第二母胶形式加入所述第一母胶中。
所述湿法混炼为橡胶溶液/填料连续液相混炼,具体为在橡胶溶液中加入第一填料,混合分散均匀后注入凝聚器内凝聚,然后脱溶剂并干燥得到第一母胶,其中的凝聚包括液体介质凝聚、气体介质凝聚、无介质凝聚的至少一种。所述加入第一填料时还可加入添加剂,所述添加剂为本领域常规使用的添加剂即可。
所述橡胶溶液中的溶剂均为各种橡胶的良溶剂。溶剂具体可以是脂肪烃溶剂、芳香烃溶剂、氯化烃溶剂、酮类溶剂、醚类溶剂和酯类溶剂,所述脂肪烃溶剂包括但并不限于各种溶剂汽油、环烷烃、取代环烷烃、直链和支链烷烃,所述芳香烃溶剂包括苯、甲苯、二甲苯、苯乙烯,所述氯化烃溶剂包括二氯甲烷、三氯甲烷、四氯化碳、二氯乙烷、氯苯、四氯乙烯、氯甲苯。橡胶在溶液中的浓度范围为1%重量至60%重量,优选5%重量至40%重量,更优选10%重量至30%重量。
