Problems solved by technology

However, the processability of lignocellulosic raw materials is poor, therefore, lignocellulose must be properly modified before it can be used as a raw material for rubber composites
[0005] At present, there are few studies on styrene-butadiene rubber composite materials. How to make styrene-butadiene rubber composite materials with good compatibility and excellent processing performance has become a technical problem that needs to be solved at present.

Abstract

The invention discloses a butadiene styrene rubber/white carbon black/lignocellulose/montmorillonite rubber composite material. Lignocellulose is modified by graphene oxide and a titanate coupling agent, and then the modified lignocellulose is compound with the white carbon black and montmorillonite to obtain a compound reinforcing agent of butadiene styrene rubber. Tensile strength, hardness and anti-slippery performance of the rubber composite material are improved. The invention also discloses a preparation method of the butadiene styrene rubber/white carbon black/lignocellulose/montmorillonite rubber composite material. By means of the natural and reproducible lignocelluloses, wastes are turned into resources. The white carbon black/lignocellulose/montmorillonite compound reinforcing agent has excellent reinforcing effect on the butadiene styrene rubber, thereby improving processability of the material. The preparation method of the rubber composite material is simple and is environment-friendly and zero-pollution.
