Preparation, structure, performance, industrialisation and application of advanced rubber/clay nanocomposites based on latex compounding method

In this paper, the research progress of compounding method using pristine clay and commercialised rubber latex to produce rubber/layered silicate nanocomposites, namely, latex compounding method, is summarised. The properties of a series of rubber/clay nanocomposites prepared by latex compounding method are systematically presented. Latex compounding method is a low cost and easily controlled process, and quite promising to be industrialised. The resulting structure of the nanocomposites by latex compounding method is either 'separated structure' or 'intercalated structure'. The nanocomposites exhibited desirable properties, such as excellent tensile strength, superior gas barrier property, improved flame retardant property, outstanding antifatigue properties, etc. As a result, the first production line of kiloton clay/rubber nanocomposites materials in China was established and a 10 000 ton scaled production line is being constructed. The applications of the nanocomposites in tire inner tube, tire inner liner, off the road tire tread and conveyer belt are investigated and initially presented.
