AI Technical Summary

Problems solved by technology

Many anti-corrosion methods used in the past, such as coating anti-corrosion paint, metal spraying, epoxy coating, cement coating, anti-corrosion paste, anti-corrosion tape and other coating methods, are suitable for various special-shaped pipelines, protruding edges, valves, spherical Contacts, screws, nuts and other special parts and complex-shaped structural objects have limited fit and tightness, and it is difficult to resist external forces that cause expansion, bending, and deformation of the protected object to cause cracks, and even the penetration of corrosive media such as moisture and air. , resulting in short corrosion life
Moreover, the surface of the coated protection must be thoroughly cleaned before coating, which is time-consuming, labor-intensive, high labor costs, and low construction efficiency
In addition, the pollution caused by dripping or splashing during coating is also very serious.

Abstract

The invention relates to a rust-proof anti-corrosion adhesive tape, and in particular relates to an oxidative polymerization type rust-proof anti-corrosion adhesive tape for the rust protection and corrosion protection of power plant steel structures, bridge stay cables, various storage tank margin plates, oil and gas pipelines, valves, flanges, I-shaped steels, spherical junctions, screws, nuts, various mechanical equipment with complicated shapes and the like. The rust-proof anti-corrosion adhesive tape comprises the following ingredients in percentage by weight: 5-7% of polyester non-woven cloth, 20-28% of linseed oil, 25-33% of aluminium hydroxide, 10-22% of magnesium hydroxide and 10-12% of organic bentonite. A compound soaked on the rust-proof anti-corrosion adhesive tape has good permeability and can permeate to a rusting layer to inhibit rust deterioration; the adhesive tape has good adhesive force, can prevent metal from contacting with corrosive media such as water, air and the like and has well corrosion resistance; and the adhesive tape has good flexibility and structural displacement fitting capability, can be attached to various complicated parts in a levelling state after adhering or winding and effectively prevent cracking.

Description

technical field [0001] The invention relates to an anti-rust and anti-corrosion adhesive tape, specifically for steel structures in power plants, stay cables of bridges, edge plates of various storage tanks, oil and gas pipelines, valves, flanges, I-beams, spherical joints, screws, Anti-rust and anti-corrosion oxidation polymerized anti-rust and anti-corrosion adhesive tape for nuts and various complex-shaped mechanical equipment. Background technique [0002] Steel structures of power plants, bridge stay cables, edge plates of various storage tanks, oil and gas pipelines, valves, flanges, I-beams, spherical joints, screws, nuts, and various complex-shaped mechanical equipment and other steel structures.
