摘要

将“绿色”轮胎的胎面进行热解和水蒸气处理，获得了固体产品SiO2D。经IR-FTIR和EDXRF光谱分析发现，该产品含有65%的SiO2, 30%的碳，3%的ZnO和2%的其他成分。研究了不同SiO2D填充量的sSBR/ br基共混体系与传统SiO2和炭黑以2:1的比例填充体系的力学、动态性能和SEM显微图。研究了含氧化锌的复合材料以及含长链脂肪酸锌盐的复合材料。用SiO2D填充的硫化胶和用传统SiO2和炭黑以2:1的比例填充的硫化胶的机械性能(模量300、抗拉强度、耐磨性等)和动态性能(热积聚、tan δ等)都没有差异。SiO2D颗粒的大小与传统SiO2颗粒的大小相同。它们在橡胶基体中的分布也没有差别。

Silica Obtained Via Pyrolysis of Waste ‘Green’ Tyres - A Filler for Tyre Tread Rubber Blends

A solid product SiO2D has been obtained as a result of subjecting the tread of ‘green’ tyres to pyrolysis-cum-water vapor. It has been found by IR-FTIR and EDXRF spectroscopy that the product contains 65% of SiO2, 30% of carbon, 3% of ZnO, and 2% of other components. The mechanical and dynamic properties, and SEM micrographs of the vulcanizates of model sSBR/BR-based blends having a different SiO2D filler content have been compared to those of vulcanizates filled with conventional SiO2 and carbon black at a 2 : 1 ratio. Composites comprising ZnO as well as such comprising zinc salts of long-chain fatty acids have been investigated. Differences have been established neither in the mechanical properties (Modulus 300, tensile strength, abrasion, etc.) nor in the dynamic properties (heat build-up, tan δ, etc.) of the vulcanizates filled with SiO2D and of those filled with conventional SiO2 and carbon black at a 2 : 1 ratio. The size of SiO2D particles has been found to be the same as that of conventional SiO2. Their distribution in the rubber matrix also does not differ.
