Anticorrosion tape and preparation method thereof

Abstract

The invention discloses an anticorrosion tape. The anticorrosion tape comprises, from top to bottom, a thin-film layer (1), an anticorrosion wearing layer (2), a connection layer (3) and a binder layer (4). The invention also discloses a preparation method for the anticorrosion tape. The preparation method comprises the following steps: heating the anticorrosion wearing layer (2) and the connection layer (3), and subjecting the anticorrosion wearing layer (2), the connection layer (3), the thin-film layer (1) and the binder layer (4) to rolling together so as to form the anticorrosion tape; or heating the anticorrosion wearing layer (2) and the connection layer (3), then subjecting the anticorrosion wearing layer (2), the connection layer (3) and the thin-film layer (1) to rolling so as to form an outer surface layer anticorrosion tape, and compounding the outer surface layer anticorrosion tape with the binder layer (4) so as to form the anticorrosion tape. The anticorrosion tape for a pipeline in the invention has the advantages of environment friendliness, high strength, good toughness, resistance to friction, water, moisture, high and low temperature and corrosion, long service life, etc.

Description

technical field [0001] The invention belongs to the technical field of pipeline anticorrosion materials, and in particular relates to an anticorrosion tape and a preparation method thereof. Background technique [0002] At present, in the field of pipeline anti-corrosion, especially in the field of oil and gas gathering and transportation pipelines on the surface of oil fields, the anti-corrosion pipelines used are still traditional petroleum asphalt pipes, glass steel pipes, polyethylene tape anti-corrosion pipes, etc. These products have exposed some problems in practical applications. , high energy consumption, polluting the environment, poor thermal shrinkage, poor adhesion between layers and many other problems, reducing the service life. [0003] The application number is 201220444716.7, which discloses a corrosion-resistant and anti-corrosion belt. In this patent, the base material PVC and glass fiber cloth are vulcanized and connected by fluorosilicone rubber. The st...
