Problems solved by technology

However, due to the high salinity and high humidity in the marine environment, it is one of the most corrosive natural environments. Therefore, the corrosion and protection of steel materials in the marine environment is an important issue that plagues human ocean development activities.
At present, in the marine atmospheric environment, the conventional means of protection are generally protection such as coating and butter, but long-term practice has shown that due to the high corrosiveness of the marine atmosphere, conventional means can no longer provide good protection.
In particular, the commonly used organic systems such as two-component protective agents have the disadvantages of serious environmental pollution and complicated construction. Therefore, the research on self-curing anti-corrosion protective agents for marine and atmospheric environments is of great significance

Abstract

The invention belongs to the field of metal corrosion protection and particularly relates to a self-setting anti-corrosion protective agent applicable to marine atmosphere environment and preparationand application thereof. The self-setting anti-corrosion protective agent applicable to the marine atmosphere environment is composed of, by weight percentage, 57-65% of base emulsion, 2-4% of anti-corrosion strength enhancer, 22-29% of main filler, 2-5% of emulsion auxiliaries and 0-6% of pigments, wherein the anti-corrosion strength enhancer is composed of nano cerium oxide and silane surfactantat a weight ratio of 1:0.05. The self-setting anti-corrosion protective agent applicable to the marine atmosphere environment has the advantages of being environmentally friendly, green and free fromtoxicity, and by adding the nano cerium oxide modified by silane, achieves corrosion resistance and ageing resistance and greatly improves the protecting effects.

Description

technical field [0001] The invention belongs to the field of metal anticorrosion, and in particular relates to a self-curing anticorrosion protective agent suitable for marine and atmospheric environments and its preparation and application. Background technique [0002] As the most commonly used construction material, iron and steel materials are widely used in marine environments. However, due to the high salinity and high humidity in the marine environment, it is one of the most corrosive natural environments. Therefore, the corrosion and protection of steel materials in the marine environment are important issues that plague human marine development activities. At present, in the marine atmospheric environment, the conventional means of protection are generally coatings, butter, etc., but long-term practice has shown that due to the high corrosiveness of the marine atmosphere, conventional means can no longer provide good protection. In particular, the commonly used org...
