几十年来,由于聚合物纳米复合材料能够改善机械性能、热学性能、绝缘性和阻燃性而受到广泛关注。其优势在于添加非常少(低于10%)的填料就能够实现补强效果,而传统聚合物复合材料则需要填充30%~70%。轮胎行业中,采用填料来提高橡胶的耐磨性、强度和模量。炭黑作为传统的橡胶补强填料,能够为通用橡胶提供良好的补强效果,且成本较低。现在,橡胶行业采用各种浅色填料来提高和完善弹性材料的物理性能。例如,在白色轮胎胎侧胶料中应用碳酸钙、粘土、

For decades, polymer nanocomposites have drawn much attention due to their ability to improve mechanical properties, thermal properties, insulation and flame retardancy. The advantage is that reinforcement can be achieved by adding very little (less than 10%) filler, compared with 30% to 70% for traditional polymer composites. In the tire industry, fillers are used to increase the abrasion resistance, strength and modulus of the rubber. As a traditional rubber reinforcing filler, carbon black can provide general rubber with good reinforcing effect and low cost. Now, the rubber industry uses a variety of light-colored fillers to improve and perfect the physical properties of elastic materials. For example, in the white tire sidewall compound application of calcium carbonate, clay,
