HDPE (High-Density Polyethylene) composite material for winding reinforcing pipe

Abstract

The invention relates to a HDPE (High-Density Polyethylene) composite material for a winding reinforcing pipe, which belongs to the technical field of high molecular materials and is used for solving the technical problems of unreasonable mixture ratio of a composite material, high cost and poor ring stiffness of the prepared winding reinforcing pipe existing in the prior art. The invention provides a HDPE composite material for a winding reinforcing pipe. The material comprises the following components in parts by weight: 75-85 parts of HDPE, 0.5-1.0 part of calcium carbonate, 15-25 parts of ultrafine talc powder, 2.0-5.0 parts of nanometer silicon dioxide, 3.0-6.0 parts of a modifier, 3.0-6.0 parts of a coloring agent, 0.5-0.8 part of an anti-ultraviolet agent and 0.5-1.0 part of an antioxidant, and can further comprise 0.5-1.0 part of a flame retardant and 0.5-1.0 part of a lubricating agent. The composite material disclosed by the invention has the advantages of reasonable component mixture ratio, good synergistic effect, low cost, and high mechanical property and ring stiffness on the winding reinforcing pipe.

Description

technical field [0001] The invention relates to a composite material, in particular to an HDPE composite material used for winding reinforced pipes, and belongs to the technical field of polymer materials. Background technique [0002] Winding reinforced pipe, also known as carat pipe, most of the existing HDPE winding reinforced pipe is made of high-density polyethylene (HDPE) as the main raw material, using hot winding processing technology, and polypropylene (PP) corrugated pipe as the main material. The support structure is made of pipe with high resistance to external pressure. Because the winding reinforced pipe can achieve the strength of the cement drainage pipe or even stronger; and there is no gap after the pipe is plugged in, it overcomes the phenomenon that the water inside the pipe overflows or the water outside the pipe seeps in due to the gaps existing in the plugging of the cement drainage pipe. And the use of winding reinforced pipes also has the advantages...

Problems solved by technology

When the composite material is used for pipes, it solves the problems of low-temperature brittleness, wear resistance, and aging resistance of polyethylene pipes, but it does not disclose performance parameters such as the ring stiffness of the pipes when the composite material is used for pipes, and its material High-cost raw materials such as nano-rare earths are used in the process, which also increases the production cost to a certain extent.
