Abstract

ABSTRACT The increasing number of scrapped tyres constitutes a global problem. One way of recycling them is to mill the rubber waste to produce ground tyre rubber (GTR), which is utilised as a component of fresh rubber compounds for manufacturing new tyres. This paper is focused on the characterisation and application of five grades of GTR produced via three methods: ambient, cryogenic, and waterjet milling. Each GTR was separated using sieves into five size fractions. Each fraction was mixed into a fresh rubber compound based on styrene–butadiene rubber (SBR), natural rubber (NR), and butadiene rubber (BR), designed for agricultural tyre tread. The higher Mooney viscosities of GTR-containing compounds indicate different processability while the curing properties changed only moderately. Smaller GTR particles result in better mechanical properties than larger ones. The waterjet milling process seems to be the most perspective.

通过环境磨、低温磨和水喷磨生产的磨胎橡胶:磨磨方法和粒度对农用轮胎胎面SBR/NR/BR化合物性能的影响

越来越多的废弃轮胎构成了一个全球性问题。回收它们的一种方法是将橡胶废料磨成磨碎的轮胎橡胶(GTR)，它被用作制造新轮胎的新橡胶化合物的组成部分。本文重点介绍了环境、低温和水射流三种方法生产的五种GTR的特性和应用。每个GTR用筛子分离成五个大小的馏分。将每个馏分混合成以丁苯橡胶(SBR)、天然橡胶(NR)和丁二烯橡胶(BR)为基础的新鲜橡胶化合物，设计用于农用轮胎胎面。含gtr化合物的较高穆尼粘度表明其加工性能不同，而固化性能变化不大。较小的GTR颗粒比较大的GTR颗粒具有更好的机械性能。水射流铣削工艺似乎是最有前景的。

期刊介绍： Plastics, Rubber and Composites: Macromolecular Engineering provides an international forum for the publication of original, peer-reviewed research on the macromolecular engineering of polymeric and related materials and polymer matrix composites. Modern polymer processing is increasingly focused on macromolecular engineering: the manipulation of structure at the molecular scale to control properties and fitness for purpose of the final component. Intimately linked to this are the objectives of predicting properties in the context of an optimised design and of establishing robust processing routes and process control systems allowing the desired properties to be achieved reliably.
