Abstract

The invention provides high-molecular special anticorrosive coating. The high-molecular special anticorrosive coating is prepared from the following raw materials in parts by weight: 30 to 60 parts of a castor oil modified vinyl polymer, 1 to 10 parts of a plasticizer, 0.1 to 1 part of a silane coupling agent, 0.01 to 0.1 part of a stabilizer, 1 to 10 parts of pigment and 20 to 80 parts of filling.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a special polymer anti-corrosion coating. Background technique [0002] The phenomenon that the function of the material is damaged due to the chemical or electrochemical interaction between the material and the environment is called corrosion, and the commonly referred to as corrosion refers to metal corrosion. Corrosion problems will damage equipment, cause a lot of waste of resources and energy, pollute the environment, and more seriously, cause disastrous accidents such as personal casualties. [0003] By studying the corrosion mechanism and reducing the corrosion rate by adopting reasonable material selection, applying anti-corrosion coatings, changing corrosive media (desalination, adding corrosion inhibitors, etc.), and providing electrochemical protection, the operating cycle of equipment can be greatly improved. Among them, coating anti-corrosion coatings is the most effective, ...
