Problems solved by technology

[0002] At present, the main problem of the PE surface layer of the domestic three PE anti-corrosion spiral steel pipe products is that the brittleness of the raw material after plasticization will lead to the unraveling of the winding layer, so the surface layer of the product is brittle, and the bonding effect with the adhesive resin layer is poor, and the compatibility is not good. , easy to crack or fall off. If the viscosity is too good, the PE layer material cannot be pulled into pieces. When winding, the material has a large falling force and is easy to break, resulting in unqualified products and requiring secondary rework, which virtually causes huge waste. The quality of the pipe is not effectively guaranteed, and it falls behind in the competition with other similar products

Description

Technical field [0001] The present invention relates to the technical field of spiral steel tubes, and more particularly to a three pee anti-coriased spiral steel pipe formulation and a preparation method thereof. Background technique [0002] At present, the main problems of the PE surface layers of three PE anti-corrosion spiral steel pipe products are the brittleness of the raw materials, which causes the winding layer to be opened, so the product surface is brittle, and the adhesive resin layer is poor, and the hypoal is not good , Easy to crack or fall off, if the viscosity is too good, the PE laminating sheet is not a piece, and the falling force is large, it is easy to discharge, causing unqualified products, and requires a quenching, invisible, huge waste, invisible The quality of the pipe is not effective, which falls in the lower wind in the competition with other similar products. Inventive content [0003] It is an object of the present invention to provide a three-P...
