Abstract

The invention belongs to the technical field of corrosion prevention for pipelines and particularly relates to an oil-resistant, thermal-insulating and anti-corrosion adhesive tape. The anti-corrosion adhesive tape consists of a base layer and an adhesive layer, wherein the adhesive layer is prepared from raw materials in parts by weight as follows; 50-55 parts of epoxy resin, 0.8-1 part of hydroxyl-fluoro silicone oil, 3-5 parts of zinc phosphate, 2-3 parts of silicon dioxide spheres, 0.5-2 parts of rhodamine B, 0.8-1.5 parts of sodium diethylhexyl sulfosuccinate, 5-7 parts of silicon boride, 3-5 parts of fatty acid amide and 1-2 parts of polyvinyl alcohol. The prepared anti-corrosion adhesive tape has low surface energy and high oil repelling property under the synergistic effect of all components and can have a shielding protection function in an oily environment to prevent oil from entering a material.

Description

technical field [0001] The invention belongs to the technical field of pipeline anticorrosion, and in particular relates to an oil-resistant, heat-insulating and anticorrosion adhesive tape. Background technique [0002] Anti-corrosion tape refers to the adhesive tape used for anti-corrosion winding, fungus-resistant and bacteria-resistant tape, which has good impact strength, good toughness and tensile strength, and is resistant to moisture, thermal expansion and wear. features. Polyethylene anti-corrosion tape is an anti-corrosion industrial tape composed of polyethylene base material and adhesive layer. It is mainly used for anti-corrosion on the outer surface of buried steel pipelines such as oil, natural gas transmission, chemical industry, water supply and drainage in urban construction, and gas transmission. , with the characteristics of convenient construction and no pollution. However, during the operation of polyethylene anti-corrosion tape, it will become brittl...
