Abstract

The invention belongs to the field of metal corrosion preventing, and particularly relates to a high-viscosity anti-corrosive belt suitable for the marine atmospheric environment and a preparation method and application thereof. The anti-corrosive belt is non-woven fabric on which high-temperature anti-corrosive paste impregnation is conducted. The anti-corrosive paste comprises, by weight, 28-30%of high-viscosity modified polymerized linseed oil, 2-3% of a corrosion inhibitor, 5-8% of an insulation agent and 59-65% of fire-retardant inorganic filler. The anti-corrosive belt has the advantages of excellent bonding performance, infiltration performance and anti-corrosive performance and is applied to the marine atmospheric environment with high humidity and high salinity.

Description

technical field [0001] The invention belongs to the field of metal anti-corrosion, and in particular relates to a high-viscosity anti-corrosion tape suitable for marine and atmospheric environments, a preparation method and application thereof. Background technique [0002] According to the ISO classification, the marine environment is the most corrosive natural environment. Different from the terrestrial atmospheric environment, the marine atmosphere has the corrosion characteristics of high salt content and high humidity, and the corrosion of steel structures, especially special-shaped steel structures, is significantly accelerated. The corrosion and protection of special-shaped steel structures in the marine atmospheric environment has always been a shortcoming of marine steel structure protection. At present, the conventional protection methods are generally coatings, large butter and other protection methods, but long-term practice shows that due to the high corrosiven...
