Abstract

The invention relates to a high-strength bend-resistant anti-corrosion adhesive tape which is sequentially compounded from five layers, namely an aluminum foil reflecting layer, a PE (Polyethylene) high-strength mesh layer, a polyolefine heat-shrinkable layer, a polytetrafluoroethylene layer and a composite bonding layer, in all to form a tape shape. The PE high-strength mesh layer is in a through hole structure, the aluminum foil reflecting layer can be connected with the polyolefine heat-shrinkable layer through a through hole, and the surface of the polytetrafluoroethylene layer is in a wave-shaped structure. The high-strength bend-resistant anti-corrosion adhesive tape disclosed by the invention has the advantages of convenience for use, ultraviolet resistance, high tensile and compressive strength and high corrosion-resistant property, achieves very high bending strength without being broken under relatively high strength bending and achieves good sealing property due to the stress action of the polyolefine heat-shrinkable layer.

Description

technical field [0001] The invention relates to the technical field of pipeline anticorrosion, in particular to a high-strength bending-resistant anticorrosion adhesive tape. Background technique [0002] Anti-corrosion tape refers to the adhesive tape used for anti-corrosion winding, which is divided into cold-winding tape and hot-winding tape. Cold-winding tape generally includes polyethylene type anti-corrosion tape, polypropylene reinforced fiber anti-corrosion tape, aluminum foil anti-ultraviolet anti-corrosion tape, polyethylene 660 Type adhesive tape, double-sided adhesive anti-corrosion inner tape (this type of tape is rarely used in China, but it is very practical and widely used abroad, and is generally used for export), epoxy coal tar anti-corrosion tape and rubber-plastic epoxy coal tar pitch cold wrap bring. [0003] Among them, polyethylene anti-corrosion tape and polypropylene fiber anti-corrosion tape are widely used in chemical infrastructure and pipeline e...
