Abstract

A corrosion-resistant electric power steel pipe pole belongs to the technical field of an electric power steel pipe pole. The electric power steel pipe pole includes a steel pipe pole body and a protective layer arranged at the external surface of a steel pipe pole wall. The protective layer comprises, by weight, 20-30 parts of a hydroxyethyl cellulose aqueous solution, 0.1-0.2 part of glycerin, 1-3 parts of propanediol, 3-5 parts of propylene glycol butyl ether, 60-70 parts of a pure silicone acrylic emulsion, 0.05-0.1 part of sodium trichlorophenolate, 0.1-0.2 part of magnesium hydroxide, 0.1-0.2 part of zinc dimethyldithiocarbamate, 0.1-0.2 part of castor bean carbonized powder, 0.3-0.5 part of hydroxypropyl starch ether, 0.2-0.4 part of ethylene bisstearamide, 0.05-0.1 part of aluminium-magnesium silicate, 0.05-0.1 part of corn pollen, and 0.05-0.1 part of cyclodextrin. The pH value is adjusted to 8-9. The electric power steel pipe pole is good in corrosion resistance and long in service life, and has advantages of permeability resistance, water resistance, small mass, good flexibility and high strength.

Description

technical field [0001] The invention belongs to the technical field of electric steel pipe tower rods, and relates to a corrosion-resistant electric steel pipe tower rod. The corrosion-resistant electric steel pipe tower rods of the present invention have good corrosion resistance, long service life, impermeability, waterproof, light weight and good flexibility. , The advantages of high strength. Background technique [0002] At present, there are many kinds of transmission line steel pipe towers used in my country's electric power sector, such as multi-edge steel pipe towers. However, there are some problems with steel pipe towers at present. The root is 1 meter above the ground and is easily corroded by rainwater containing corrosive media splashed from the ground, resulting in a decrease in support strength and potential safety hazards. The anti-corrosion layer on the outer surface of the root has low strength. , Easy to be scratched and damaged, poor anti-corrosion effe...
