Polyurethane raw materials is active elastomer material, the change in the shape of polyurethane lags stress time under stress so that the majority of the flushing strength stress produced under stress translate into internal energy and scatter in the form of heat energy. The remaining small portion of the flushing strength bounces back to conveying medium with polyurethane lag deformation to offset subsequent stress erosion. Therefore, the characteristics of polyurethane skillfully use the way of leveraging the power that greatly reducing the abrasion and flushing strength from transmission medium to wear-resistance layer, so as to achieve an unexpected durable effect. Many industry experts hailed it “Tai Chi” of wear-resistant industry. The carbon nanomaterials used in polyurethane is a leading international business technology. A certain proportion and complex process make it possible to complement each other’s advantages and disadvantages. As a lot of related analogue experiments and engineering applications has shown, the carbon nano polyurethane materials have been highly optimized in many aspects of physical properties, especially the anti-aging properties which does not exceed 0.26% in 50 years.
