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 anticorrosion, and in particular relates to a self-curing anticorrosion protective agent suitable for marine and atmospheric environments and its preparation and application. The self-curing anti-corrosion protective agent is calculated by weight percentage, 57-65% base emulsion, 2-4% corrosion resistance and strength enhancer, 22-29% main filler, 2-5% emulsion formulation and 0-6% pigment; The corrosion resistance and strength enhancer are nano cerium oxide and silane surface modifier, and the mass ratio of nano cerium oxide to silane surface modifier is 1:0.05. The invention makes the obtained anti-corrosion protective agent have the characteristics of environmental protection, greenness and non-toxicity, and the addition of silane-modified nano-cerium oxide makes it obtain excellent corrosion resistance and aging resistance, greatly improving the protective effect of the protective agent.

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...
