Abstract

The invention discloses a method for preparing a high-strength and high-toughness double-wall corrugated water discharge pipe material by using waste beverage bottles. The method comprises: S1, pretreatment of waste beverage bottles; S2, chain extension of the waste beverage bottles; and S3, molding of water discharge pipe material. The invention further discloses the high-strength and high-toughness double-wall corrugated water discharge pipe material prepared according to the method. According to the invention, with the method, the resource recycling of waste beverage bottles can be efficiently and rapidly achieved, waste can be turned into wealth, the double-wall corrugated water discharge pipe with characteristics of high strength, high toughness, good weather resistance, good flame retardance, good high-temperature resistance and long service life can be manufactured, and high economic value, social value and ecological value are achieved.

Description

Technical field [0001] The invention relates to the technical field of pipes, in particular to a method for preparing high-strength and high-toughness double-wall corrugated pipes by using waste beverage bottles. Background technique [0002] At present, cement and metal drainage pipe construction methods are mainly used in the construction of outdoor buried drainage pipes in municipal engineering rainwater and sewage discharge, industrial wastewater discharge, community drainage projects, and embedded pipelines. The construction speed is slow and the pipes are heavy. , The transportation is inconvenient, the labor intensity is high, and the installation cost is high, which wastes both material resources and human resources. [0003] Double-wall corrugated drainage pipe is a kind of plastic structure wall pipe developed in recent years. It is mainly used as sewage river drainage pipe, especially large-diameter corrugated pipe. It generally uses high-density polyvinyl chloride as ra...
