纳米层状硅酸盐在轮胎气密层中的应用研究

聚合物纳米复合材料因其分散相的高度精细化和纳米尺寸效应而具有与传统复合材料明显不同的力学性能和功能性能。其中,层状硅酸盐聚合物纳米复合材料又以分散相的高形状系数比而具有更为突出或特异的性能,如高刚性、高强度、高阻隔、高阻燃性等。因此聚合物纳米复合材料自问世以来便受到各国学者和工业界广泛关注。在轮胎气密层橡胶中,可以充分利用纳米层状硅酸盐材料的高阻隔性,从而起到提高气密性的作用。更进一步的应用研究表明,可以通过使用纳米层状硅酸盐填充橡胶作为气密层,在不损失气密性的情况下,减少气密层厚度,从而降低轮胎重量,实现原价节俭和滚动阻力降低的双重效果。

Study on application of nano layerd Mg-silicate in tire inner liner

Polymer nano composites has different phsical and functional properties because of its high sophisticated fillers and nanometer size effect. With high structure ratio fillers, nano layerd silicate composite has more standing and excellent properties. Such as: high rigidity, high strength, high air resistance and high flame retardent. So, this kind of materials are focused by researchers and industry. In tire industry, this composites can be used in inner liner to recieve better air resistance property. Further study shows that inner liner thickness can be small by using nano layerd composites to make tire weight down. Then both tire material cost and rolling resistance will be down.
