▎ 摘  要

NOVELTY - Reinforced wear-resistant polyethylene water supply pipe comprises a pipe body (1), and the pipe body comprises a pressure-resistant layer (101) and a compatible layer (102). The compatibility layer is arranged inside the pressure-resistant layer. A wear-resistant layer (2) is provided on the inner side of the compatible layer. The pressure-resistant layer comprises 94.5-95.5% polyethylene resin, and 4.5 -5.5% Graphene black masterbatch. The compatibility layer s a polyethylene graft resin. The wear-resistant layer comprises 94.5-95.5% block copolymer polypropylene, 4.5 -5.5% graphene black masterbatch, or 94.5-95% ultra-high molecular polyethylene, and 4.5-5.5% graphene black masterbatch. USE - The water supply pipe is useful for trenchless construction. ADVANTAGE - The water supply pipe: is fast and convenient; has high work efficiency; saves costs; avoids the accumulation of wear-resistant paint on the inner bottom of the pipe body; has uniform thickness of the wear-resistant layer and more flexible spraying mechanism; and ensures wear resistance of the pipe body, which can be applied to the spraying work of long-length pipelines. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing a reinforced wear-resistant polyethylene water supply pipe for trenchless construction. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the reinforced wear-resistant polyethylene water supply pipe for trenchless construction.
