Abstract

The invention relates to a polyethylene pipe bonding material and a preparation method thereof. By selecting metallocene MDPE and HDPE for blending and LLDPE, sarin resin and POP for supplementing toperform maleic anhydride grafting reaction on a polyethylene polymer chain during melt blending, the polyethylene pipe bonding material is prepared, and the polyethylene pipe bonding material has tensile strength greater than 25 MPa, impact strength greater than 32 kJ/m<2>, melt flow rate less than 3.8 g/10 min and peel strength greater than 13.8 N/mm, while the higher peel strength greatly increases the bonding density of the polyethylene pipe bonding material with steel wires or steel pipes; the polyethylene pipe bonding material is applied to high-speed plastic coating of a steel wire meshin a steel wire reinforced polyethylene pipe, and can also be applied to bonding a steel pipe coated with epoxy powder and outer layer PE in a 3PE anticorrosive pipe; the bonding material has better bonding performance with the steel wires or steel pipes.

Description

technical field [0001] The invention relates to the technical field of polyethylene polymer materials, in particular to a polyethylene pipe bonding material and a preparation method thereof. Background technique [0002] Steel wire-wound reinforced polyethylene composite pipe is a kind of pressure-resistant pipe that combines the high strength of steel wire with the hygienic and anti-corrosion properties of polyethylene. Due to the introduction of helically wound reinforced steel wire, the composite pipe has a higher pressure resistance level, and at the same time can greatly reduce the wall thickness of the pipe, and has the advantages of light weight, low cost, and convenient transportation and transfer. Due to the excellent stability and pressure resistance of the composite pipe, it has obvious advantages in long-distance water supply and gas supply applications. At present, such pipelines are widely used in municipal water supply, agricultural irrigation, roads and brid...
