Abstract

The invention belongs to the technical field of anticorrosion, and particularly relates to a sealing material used for anticorrosion of special-shape components. The sealing material is composed of afirst component and a second component, which are uniformly mixed according to weight ratio of first component to second component of 100:40 to 60:8. Then the mixture coats the surface of a special-shape component or fills gaps therein; after 1-2 h, the material is cemented and not flows anymore, and after 36 h at room temperature, the material is completely cured. The sealing material solves theproblem that the anticorrosive material for special-shape components in the prior art cannot satisfy the demand of coating on special-shape components. The sealing material can form a thick and full coating layer, has wettability and permeability, has airtightness and barrier effect, is cold and heat resistance, is long-lasting and durable, is free of trace after detachment, can be applied with moisture and rust, allows normal temperature construction, can save manpower and material, and is environment-friendly and low-cost.

Description

technical field [0001] The invention belongs to the technical field of anticorrosion, and in particular relates to a sealing material used for anticorrosion of special-shaped components. Background technique [0002] At present, in the field of corrosion control, the anticorrosion of special-shaped metal components has always been a difficult problem, so it is always the most severely corroded part. Outdoor valves, tees, bolts, expansion joints, flange gaps and other heterogeneous metal components are almost covered with rust after 1-2 years of use. Due to the complexity of the shape and the fear of leakage in some cases, it is almost impossible to thoroughly derust the surface of these rusty special-shaped components in reality. [0003] In addition, the corrosion of special-shaped metal components is much faster than that of regular components. This fact is also related to the complexity of its shape and the incompatibility of traditional anti-corrosion coatings. Due to ...
