Abstract

The recycling of zinc compound from waste tires and the negative impact of zinc oxide on environment have been major challenges in rubber industry. In this study, the components and microstructure of recovered carbon black (rCB) from waste tires pyrolysis are analyzed, in which the content of the ash and zinc element is 20 % and 6.1 %, and zinc sulfide is the main zinc compound. Zinc sulfide and zinc oxide could crosslink brominated butyl rubber (BIIR), and the crosslinking effect becomes more effective in the presence of carbon black N660. BIIR can be crosslinked and reinforced by rCB in the absence of other additives. BIIR/rCB composites have similar curing behavior and mechanical properties to the BIIR composites filled with N660 and cured by zine oxide. Therefore, rCB could replace commercial carbon black N660 and zinc oxide in BIIR, and this replacement will realize the effective use of carbon black and zinc compound in rCB from waste tires and promote the sustainable development of tire industry.

废轮胎回收炭黑对溴化丁基橡胶的硫化和补强效果

从废轮胎中回收锌化合物以及氧化锌对环境的负面影响一直是橡胶工业面临的主要挑战。本研究分析了废轮胎热解回收炭黑（rCB）的成分和微观结构，其中灰分和锌元素的含量分别为 20 % 和 6.1 %，硫化锌是主要的锌化合物。硫化锌和氧化锌可以交联溴化丁基橡胶（BIIR），在炭黑 N660 的存在下交联效果更佳。在不使用其他添加剂的情况下，溴化丁基橡胶可以通过 rCB 进行交联和增强。BIIR/rCB 复合材料的固化行为和机械性能与填充 N660 并用氧化锌固化的 BIIR 复合材料相似。因此，rCB 可以替代 BIIR 中的商品炭黑 N660 和氧化锌，这种替代将实现废旧轮胎 rCB 中炭黑和锌化合物的有效利用，促进轮胎工业的可持续发展。
