Technical Field

The invention relates to the technical field of rubber hoses, in particular to a high-performance wax film large-caliber rubber hose.

Background

The production process of the water hose commonly applied generally uses polyester industrial yarns as a woven layer, and inner and outer rubber layers as anti-leakage and wear-resistant layers. Compared with other high polymer pipes, the rubber hose has the advantages of excellent chemical and mechanical resistance, good elasticity, good aging performance and the like, so that the rubber hose has a great application field.

The existing rubber co-extrusion water band production process comprises the following steps:
