Abstract

The invention relates to a polyethylene adhesive tape and a preparation method thereof. The polyethylene adhesive tape comprises a thin film substrate layer, an organic silicone oil layer and an adhesive layer. The preparation method comprises: selecting a PT thin film substrate; coating organic silicone oil on a surface of a side of the PT thin film substrate, simultaneously carrying out baking in a baking channel; carrying out winding after removing from the baking channel, followed by aging standing at a room temperature; coating an adhesive on the surface of the other side of the stood PT thin film substrate, simultaneously carrying out baking in the baking channel; carrying out winding after removing from the baking channel, followed by aging standing at the room temperature; carrying out splitting after standing to obtain the finished product of the polyethylene adhesive tape. Compared to the prior art, the production process provided by the present invention has characteristics of simplicity, no toxic solvent consuming, high production efficiency, good product performance, and can be widely applicable for external corrosion protection for various steel pipes.

Description

technical field [0001] The invention relates to a polyethylene adhesive tape and a production method thereof, in particular to a polyethylene adhesive tape used for wrapping the outer wall of a metal pipeline to prevent corrosion and a production 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. [0003] The prior art discloses a method of using adhesive tape for anticorrosion. By wrapping sticky and waterproof adhesive on the surface of the pipeline, the problem of anticorrosion of buried pipelines is brought about. Compared with other anticorrosion materials for pipelines, it has better anticorrosion performance an...
