Technical Field

The invention relates to the technical field of materials, in particular to a special anticorrosive paint for a water-based nano tank car and a preparation method thereof.

Background

Corrosion is one of the biggest challenges facing industries such as steel, metallurgy, construction, transportation and the like, and the direct economic loss caused by corrosion is about 2.5 trillion yuan each year around the world. Coating the surface of a metal substrate with one or more corrosion protection coatings is an important way to protect the article from corrosion. Currently, several commonly used anticorrosive coatings include epoxy systems, acrylic acid systems, polyurethane systems, alkyd systems, and the like. With the increasing importance of environmental protection and sustainable development in various countries in the future, the solvent-based coating is increasingly limited due to excessive VOC emission, and the water-based coating is increasingly favored by the market due to environmental friendliness.

The application research and practice at home and abroad proves that the eucommia bark rubber has unique rubber-plastic duality and extremely high adhesive property, so that the performance of the eucommia bark rubber is greatly superior to that of natural rubber produced by the hevea trees in many aspects, and various special rubber products with excellent comprehensive performance, which are suitable for the fields of aviation, navigation, medical treatment and the like, can be prepared by blending or modifying the eucommia bark rubber with the hevea rubber, other synthetic rubber and plastics, and can also be used for producing safe and long-life oil-saving tires and other rubber products.

In conclusion, the special anticorrosive paint for the water-based nano tank car and the preparation method thereof, which can meet the comprehensive performance requirements, are lacked in the field.
