Study on Preparation,Industrialization and Application of Clay/Rubber Nanocomposites
Clay/polymer nanocomposites have attracted great interests in the field of materials science and engineering for some superior properties. However, further development is limited by reasons like high price/performance ratio and deficiency in some properties. To break through the bottleneck we have to (1) develop preparation techniques with low cost; (2) exploit the acquired excellent properties and find optimum application fields. In this report, the compositing method using pristine clay and commercialized rubber latex to produce layered silicate/rubber nanocomposites, namely latex compounding method (recognized internationally), is introduced. The unique compositing mechanism and structure of the obtained nanocomposites are discussed, and properties of series of clay/rubber nanocomposites prepared by this method are systematically presented. Latex compounding method is a low-cost and easily controlled process, and quite promising to be industrialized. The structure of the nanocomposites is either Separated Structure or Intercalated Structure. The nanocomposites show desirable properties, such as excellent tensile strength,superior gas barrier property, improved flame retardant property, outstanding anti-fatigue properties, etc. In addition, the first production line of kiloton clay/rubber nanocomposites materials in China is introduced. The applications of the nanocomposites in tyre inner tube, tyre inner liner, OTR tyre tread and conveyor belts are presented. In the end, the directions in future development of the nanocomposites in research and applications will be discussed.
