Problems solved by technology

The HDPE double-wall corrugated pipes used in drainage and sewage pipes in my country have the advantages of good rigidity and low price; however, they also have the disadvantage of poor low-temperature impact performance, and are easily damaged during construction in winter in the north.
PE double-wall corrugated pipe has obvious advantages in low temperature toughness, but due to the characteristics of PE material, its rigidity is worse than that of cement pipe, and the ring stiffness and creep resistance of the pipe are worse than HDPE corrugated pipe. During long-term use, it is easy to Deformed by gravity, affecting the service life of the product

Abstract

The invention relates to an HDPE (High-Density Polyethylene) steel belt reinforced spiral corrugated pipe and a production process thereof. The HDPE steel belt reinforced spiral corrugated pipe is prepared from the following raw materials in parts by weight: 50 to 70 parts of HDPE, 20 to 28 parts of high-modulus PP (Polypropylene), 4 to 7 parts of attapulgite, 25 to 30 parts of HDPE stiffened master batch, 26 to 29 parts of HDPE toughened master batch, 5 to 8 parts of polyester modified acrylic resin, 2 to 4 parts of siloxane modified acrylic resin, 4 to 7 parts of ABS (Acrylonitrile-Butadiene-Styrene) high glue powder, 1 to 4 parts of acrylic impact modifier ACR and 5 to 8 parts of color master batch. A mining HDPE double-wall corrugated composite pipe made by the production process has high low-temperature toughness, high rigidity, high ring stiffness and high creep resistance, and is not be deformed by gravity in a long-term use process, thus prolonging the service life of a product; the HDPE steel belt reinforced spiral corrugated pipe can be popularized on a large scale.

Description

technical field [0001] The invention relates to a HDPE steel strip reinforced spiral corrugated pipe and a production process thereof, belonging to the technical field of plastic pipe processing. Background technique [0002] With the sustained and stable high-speed growth of my country's national economy, it provides a good macro environment and broad space for urban infrastructure construction. With my country's increasing emphasis on environmental protection, governments at all levels from the central government to local governments have issued a series of policies and regulations on water conservation, pollution control and environmental protection. Water supply, water saving, drainage and sewage treatment will become the focus of urban municipal construction in the future, which provides market development space for the promotion and application of large-diameter plastic pipes. Because structural wall pipes can save raw materials and reduce costs, structural wall pipes...
