Abstract

The invention discloses a polyethylene anticorrosion adhesive tape with good soil stress resistance and a preparation method thereof; the adhesive tape is composed of a polyethylene base film and an adhesive layer; the polyethylene base film is made from such as low-density polyethylene, high-density polyethylene, vinyltri(tert-butoxy)silane, bismaleimide, ethylene-vinyl acetate copolymer, nano silicon dioxide, antimony trioxide, promoter DM, magnesium stearate and an isocyanate at a certain ratio; the adhesive layer is made from butyl rubber, bisphenol-A epoxy resin, 2,6-ditert-butyl-4 cresol, nano zinc oxide, magnesium oxide, acetone, dibutyl phthalate, iron powder, boron powder, kaolin, crosslinking agent DCP, amino silicone oil, copper 8-hydroxyquinoline, a lignosulfonate, vinyltri(tert-butoxy)silane, organosilicon resin, and polyamide at a certain ratio. The adhesive tape prepared herein has excellent properties, has excellent corrosion resistance, and has good soil stress resistance and long service life up to 50 years and longer.

Description

technical field [0001] The invention relates to an adhesive tape, in particular to a polyethylene anti-corrosion adhesive tape with strong resistance to soil stress and a preparation method thereof. Background technique [0002] As we all know, it is the most economical and convenient way to transport crude oil, refined oil, intermediates, natural gas, etc. using buried pipelines in petroleum and chemical industries. Because most of the existing buried pipelines are iron pipelines, the biggest problem after they are buried underground is exactly the problem of anti-corrosion and anti-theft. The damage, stripping and aging of the anti-corrosion layer of buried oil and natural gas pipelines will cause corrosion, perforation and leakage of pipelines, which will bring serious property losses to enterprises and bring harm to the public and the environment. It is not uncommon for my country's underground oil and gas pipelines to be corroded and perforated 1-2 years after they are...
