High-abrasion-resistance rubber/phyllosilicate nano composite material fabric core conveyer belt cover rubber and preparation method thereof

The invention discloses a high-abrasion-resistance long-service-life rubber/phyllosilicate nano composite material fabric core conveyer belt cover rubber and a preparation method thereof. The preparation method comprises the following steps: selecting excellent-abrasion-resistance butadiene styrene rubber and high-elasticity natural rubber as main raw materials, preparing nano phyllosilicate by an intercalation process, and intensely mixing the nano phyllosilicate with the rubbers and a compounding agent thereof by a mechanical blending process to prepare the rubber/phyllosilicate nano composite material cover rubber. Since the phyllosilicate in the prepared composite material is uniformly dispersed in the system in a nano lamina mode; and the phyllosilicate has favorable binding force with the rubber base, thereby greatly synchronously enhancing the abrasion resistance, tearing strength, aging resistance, dielectric resistance, heat resistance, flame retardancy and the like of the composite material and the conveyer belt, and prolonging the service life of the conveyer belt. The conveyer belt prepared by the cover rubber has the advantages of long service life and high cost performance. The invention has important application value.
