R and D and application on a new kind of flexible rubber-plastic: Water-storing equipment

Aiming at disadvantages of traditional cells and present large plastic containers for rainwater storing, new equipment was developed. The equipment's typical characteristics were protecting water quality and being folded for being transported expediently. The main materials of the equipment consisted of two layers of canvas and three layers of rubber. In order to protect the water quality, a kind of special coat of the inner layer was given. The inner layer was made of natural rubber (C5H8)n, food grade softening oil, carbon black, nanometer calcium filler, antioxidant and sulfide. The result of primary application indicated that the material had no bad effect on water quality, which could meet the related national standards in China. Compared with traditional water-storing equipment, this equipment could save in investment by 20% - 30% and 80% of construction time.
