Embodiment 1

[0020] A steel pipe anticorrosion treatment method is carried out in the following order:

[0021] (1) Pickling the steel pipe first;

[0022] (2) Wash the cleaned steel pipe with water and let it dry naturally;

[0023] (3) Dip the cleaned and dried steel pipe into the molten surface treatment agent to form an anti-corrosion coating. The surface treatment agent is composed of the following components and proportioned by weight percentage: polytetrafluoroethylene 6%, two Methylformamide 12%, Trifluoroacetyl Chloride 4%, Triethyl Benzene Tricarboxylate 3%, Zinc Undecylenate 6%, Carbon Nanotube 6%, Trifluoroethyl Acrylate 6%, Nano Diamond 8% , magnesium reagent 2%, dioctyl sebacate 5%, diphenylphosphoryl chloride 2%, amino 8%, alkoxy 12%, silane 20%.

[0024] (4) Put the soaked steel pipe into the furnace for drying, raise the furnace temperature to 120°C, keep it for 9 hours, then raise the furnace temperature to 180°C, keep it for 24 hours, and cool down to room temperature ...

Abstract

The invention discloses a steel pipe surface treating agent and an anti-corrosion treatment method. The surface treating agent is composed of the following components in percentage by weight: 3%-9% ofpolytetrafluoroethylene, 6%-12% of dimethyl formamide, 3%-6% of trifluoroacetyl chloride, 1%-3% of triethyl phenyltricarboxylate, 3%-6% of zinc undecylenate, 6%-8% of carbon nanotubes, 2%-6% of trifluoroethyl acrylate, 5%-8% of nano diamond, 1%-3% of a magnesium reagent, 3%-6% of dioctyl sebacate, 1%-3% of diphenyl phosphoryl chloride, 2%-8% of amino, 6%-12% of alkoxy and 10%-20% of silane. The steel pipe surface treating agent can effectively prevent a steel pipe from being corroded, the service life of the steel pipe is prolonged, the strength of the steel pipe is effectively improved, andapplication prospects are good.

Description

technical field [0001] The invention relates to the technical field of pipelines, in particular to a steel pipe surface treatment agent and an anti-corrosion treatment method. Background technique [0002] Steel pipes have a hollow section whose length is much greater than the diameter or circumference of steel. According to the cross-sectional shape, it is divided into circular, square, rectangular and special-shaped steel pipes; according to the material, it is divided into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes and composite steel pipes; Steel pipes for thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment, etc.; according to the production process, they are divided into seamless steel pipes and welded steel pipes, among which seamless steel pipes are divided into hot-rolled and cold-rolled (drawn) Two kinds, welded steel pipe is divided into straight seam welded steel ...
