Vegetable oil-based metal anticorrosion coating and preparation method thereof

Abstract

The invention relates to the field of polymer materials, and concretely relates to a vegetable oil-based metal anticorrosion coating completely using a biomass substance and having the advantages of strong adhesion with steel, good anticorrosive effect, renewability, safety, economical property, moderate curing speed, good weather resistance, wide application range, greenness, environmental protection and excellent comprehensive performances, and a preparation method thereof. A preparation formula of the coating includes a component A and a component B according to a mass ratio of 5:1 to 5:4.The component A and the component B are uniformly mixed according to the above mass ratio, and then can be pasted to a substance for preventing adhesion, and the two components are separately stored when not used.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a vegetable oil-based metal anti-corrosion coating and a preparation method thereof. Background technique [0002] At present, the annual economic losses caused by metal corrosion in our country account for about 2% to 4% of the gross national product, and some developed countries are even higher; metal corrosion has caused a lot of waste of metal resources and energy; the production of metal materials not only needs to consume A large amount of metal ore, and it needs to consume a lot of energy; and the corrosion of metals causes equipment damage accidents and environmental pollution problems; sudden accidents such as equipment corrosion, perforation, and fracture often lead to catastrophic consequences, and material loss and runaway caused by equipment corrosion Drip leaking is an important cause of environmental pollution; metal corrosion also seriously hinders the development...

Problems solved by technology

[0002] At present, the annual economic losses caused by metal corrosion in our country account for about 2% to 4% of the gross national product, and even higher in some developed countries; metal corrosion has caused a lot of waste of metal resources and energy; the production of metal materials not only consumes A large amount of metal ore, and it needs to consume a lot of energy; and metal corrosion causes equipment damage accidents and environmental pollution problems; sudden accidents such as equipment corrosion, perforation, and fracture often lead to catastrophic consequences, and material loss and runaway caused by equipment corrosion Dripping and leaking is an important cause of environmental pollution; metal corrosion also seriously hinders the development of new technologies; therefore, the research of metal anti-corrosion materials is particularly important

[0003] The corrosion prevention of metal materials can be divided into electrochemical corrosion, chemical corrosion, physical corrosion, etc. The organic anti-corrosion method layer is widely used because of its convenient construction and good anti-corrosion effect; Organic solvent-based anti-corrosion paints are mainly used, but because most of the organic solvents they contain are flammable, volatile, and smelly, they will dissolve into the water body and cause pollution to the environment; while traditional methods for preventing metal corrosion are mostly complicated in process and construction Difficult, the high cost of anti-corrosion has limited the traditional metal anti-corrosion; therefore, it is imperative to develop a metal anti-corrosion coating that is renewable, simple in process operation and low in cost.
