The invention discloses a kind of cold-tangled anticorrosion adhesive tape for pipeline anticorrosion, be made up of film layer and viscose glue oxidant layer, be combined on film layer through extruder Extrusion Coating after the mixing of described viscose glue oxidant layer each component and obtain；Described film layer is to be prepared with the copolymer of vinylacetate, Tissuemat E and butadiene-styrene rubber by Low Density Polyethylene, chlorinated polyethylene, ethylene；Described viscose glue oxidant layer is prepared by regeneration natural rubber, recovery polystyrene, paper mill sludge ash, coupling wood powder, terpene resin, polyisobutylene succinamide, nano silicon and ethoxydiglycol ether.The prepared cold-tangled anticorrosion adhesive tape for pipeline anticorrosion of the present invention is high to backing peel strength, specifically refers to the viscose glue oxidant layer back for film layer, has the highest peel strength, reach as high as 40.0N/cm, it is possible to meets anticorrosion and the reparation demand of buried steel pipe. |
