Abstract

The invention relates to a polyethylene and microcrystal ceramic composite material, prepared by the following components in parts by weight: a polyethylene resin base system, including 100 parts of HDPE (High Density Polyethylene), 1-5 parts of silicone powder, 5-10 parts of elastomer graft toughening modifier and 0.5-1 part of antioxygen 1010; a microcrystal ceramic system, including 30-56 parts of silicate microcrystal ceramic, 60-66 parts of zinc oxide (with fineness more than 800 meshes), 2-03 parts of montmorillonoid and 2-3 parts of titanate coupling agent; the weight ratio of the PED base system to the microcrystal ceramic system is 70-80 / 30-20. The polyethylene and microcrystal ceramic composite material has the advantage that, the composite material provided by the invention solves the problems that a traditional oil-gas gathering and transferring pipeline may be corroded and worn during a using process. In the formula system, the silicone powder modifies the mobility of the system, and also increases toughness of the system; similarly, the elastomer graft toughening modifier can improve the interface bonding strength of the PE base and the microcrystal ceramic, improve the mechanical strength of the composite material and meanwhile play a role in toughening the base.

Description

technical field [0001] The invention relates to the technical field of resin-based ceramic composite materials and their preparation, in particular to a functionalized, high-performance new composite material with special properties such as high anticorrosion, high strength, high temperature resistance, and high wear resistance, and a preparation method thereof. Background technique [0002] The transportation of oil and natural gas resources in my country mainly depends on pipelines, which are generally steel spiral welded pipes. Due to the complex terrain that the pipeline traverses, the environment is not only spatially different, but also subject to erosion by various media over time. 28% of leaks in these pipelines were due to corrosion perforation. Corrosion of pipelines will not only cause oil and gas leakage loss caused by perforation, fire, etc., but also waste materials and manpower caused by maintenance. [0003] The composite material of the present invention i...
