Enabling increased recycled tyre crumb content in 'safety surfaces'

2011年欧盟轮胎产量为3.02亿条，重量约为480万吨。磨损后，可回收的重量约为300万TE。轮胎回收利用有多种轮胎回收技术和多种应用。主要方法是机械回收生产轮胎胶粉。其中一些碎屑是使用水性乳液体系着色的，这些体系的耐用性相对较差，色彩范围和亮度有限。我们把轮胎回收成碎屑，用来做运动场和安全场。对于要求具有高耐用性的鲜艳/鲜艳的颜色的应用，则通常使用原始的有色三元乙丙橡胶化合物。然而，我们的新想法是使用一种改进的彩色涂层处理回收橡胶屑，这将使我们的颜色耐久性更好，颜色范围更广，颜色和亮度更鲜艳。

EU production of tyres for 2011 was 302 million units weighing ~4.8 million te. After wear, the weight available to be recycled is ~3 million te. Numerous tyre recycling technologies and several applications exist for tyre recyclate. The main method is mechanical recovery producing tyre crumb & powder. Some of this crumb is coloured using water based emulsion systems that have relatively poor durability and a limited colour range and brightness. We recycle tyres into crumb and use them for sports & safety surfaces. For applications where bright/vivid colours with high durability are required, then virgin, coloured compounds of EPDM are often used. However, our new idea is to use a modified colour coating treatment for recycled rubber crumb that will give us much greater colour durability, wider colour range and more vivid colours & brightness.
