包含玻璃泡和增韧剂的母料组合物和橡胶组合物以及相关方法
摘要：
本发明公开了一种包含在间规1,2-聚丁二烯和顺式-1,4-聚丁二烯的共混物中的玻璃泡和增韧剂的母料组合物。所述玻璃泡以基于所述母料组合物的总重量计至少25重量％的量存在。公开了一种由所述母料组合物制备橡胶组合物的方法，以及由所述母料组合物制成的橡胶组合物和硫化橡胶。也公开一种橡胶组合物，所述橡胶组合物包含间规1,2-聚丁二烯、顺式-1,4-聚丁二烯、包括氟塑料或者有机纤维或陶瓷纤维中的至少一种的增韧剂、以及基于所述橡胶组合物的总重量计至多25重量％的玻璃泡。
摘要（英）：

A masterbatch composition including glass bubbles and a toughening agent in a blend of syndiotactic 1,2-polybutadiene and cis-1,4-polybutadiene is disclosed. The glass bubbles are present in an amountof at least 25 percent by weight, based on the total weight of the masterbatch composition. A method of making a rubber composition from the masterbatch composition is disclosed as well as a rubber composition and vulcanized rubber made from the masterbatch composition. A rubber composition that includes syndiotactic 1,2-polybutadiene, cis-1,4-polybutadiene, a toughening agent that includes at least one of a fluoroplastic or an organic or ceramic fiber, and glass bubbles in an amount up to 25 percent by weight, based on the total weight of the rubber composition, is also disclosed.
