Oxidative polymerization type rust-proof anti-corrosion adhesive paste

Abstract

The invention relates to a rust-proof anti-corrosion adhesive paste, and in particular relates to an oxidative polymerization type rust-proof anti-corrosion adhesive paste. The rust-proof anti-corrosion adhesive paste comprises the following ingredients in percentage by weight: 57-63% of polybutene, 10-14% of organic bentonite, 3-5% of an antirusting agent, 0.1-1% of titanium dioxide, 0.1-1% of graphite, 26-30% of talc and 0.1-0.24% of silicon dioxide. The oxidative polymerization type rust-proof anti-corrosion adhesive paste is coated on the surfaces of protected objects, has strong adherence and permeability, can permeate to a rusting layer to inhibit rust deterioration and has good fitting tightness and sealing performance, good rust-proof and anti-corrosion performances and long service life; the adhesive paste is simple in protected object surface treatment, can be used for filling and levelling pits, can be applied to original rusty coating construction and is convenient to apply, high in efficiency and labor cost-saving; and moreover, the rust-proof anti-corrosion adhesive paste has good flexibility, ageing resistance and high-strength impact resistance and further effectively and stably prevents steel structures from being corroded for a long time, so that the protected objects can be enabled to be safely produced.

Description

technical field [0001] The invention relates to an antirust and anticorrosion adhesive paste, in particular to an oxidation polymerization type antirust and anticorrosion adhesive paste. 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. Exposure to the atmosphere, continuous exposure to wind, sun, rain, especially the influence of humid marine atmosphere, the corrosion is very serious. In order to ensure its safe operation, production, and resource conservation, it is necessary to formulate targeted anti-corrosion countermeasures. Many anti-corrosion methods have been used in the past, such as coating anti-corrosion coatings, metal spraying, epoxy coatings, cement coatings, etc. However, the cleaning requirements for the corroded surface of the pro...

AI Technical Summary

Problems solved by technology

However, the cleaning requirements for the corroded surface of the protected object are high, especially for various uneven steel surfaces, pits, gaps and complex-shaped mechanical equipment, which are difficult to clean; flexibility, sealing, impact strength and Aging resistance is limited, and the resistance to expansion, bending, and deformation of steel parts due to external forces is not ideal, and even cracks occur, which directly affects the anti-corrosion effect and anti-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 and splashing during coating is also very serious.
