Abstract:
     Waste vulcanized rubber is used as main raw material. The method includes such technological steps as brominating or oxidizing the devulcanized waste vulcanized rubber to make up high-saturation regenerated rubber, addition of less raw rubber and compounding agent, chloridizing natural rubber to imporove its anti-ageing performance, pugging, extrusion, calendering and vulcanization to obtain various water-proof materials. Its advantages are low cost, less energy consumption, and excellent anti-ageing performance for its products.
