Problems solved by technology

Although these coatings have their own advantages, they are still closed protective coatings. Once the coating is damaged, the material will be corroded quickly.
Moreover, these coatings generally have disadvantages such as easy aging, intolerance to organic solvents, toxicity, and environmental pollution, so their scope of use is limited.
Since the 1990s, paint workers began to try to introduce nano-materials into coatings, but due to the small particle size and large specific surface area of ​​nano-materials, they are prone to agglomeration during use, which greatly hinders the performance of nano-materials.

Abstract

The invention discloses a kind of new industry dope. It comprises of two kinds of materials of following weight shares: Component A 95 - 105 and Component B 2 - 8 shares; thereinto, Component A is made from such materials as membrane forming object, pigment, filling agent, auxiliary agent, compound nanometer dispersing agent and solvent; Component B is made from nanometer Sb2O3 and mixed organic solvent carriers. The dope of the invention has following advantages: at room temperature, it has prominent heavy anticorrosion performance, and has excellent performances of acid resistance, alkali resistance, salt mist resistance, oil resistance, chemical reagent resistance, waiting resistance and ultraviolet resistance; it also has excellent fire protection and waterproof performance; the clinging strength of smearing membrane is good, membrane forming speed is fast, and performance is stable.

Description

technical field [0001] The invention relates to an industrial coating, in particular to an anti-corrosion and waterproof industrial coating and a preparation method thereof, belonging to the field of chemical industry. Background technique [0002] With the development of modern industry, the emergence of a number of emerging industrial fields and the construction of many modern projects have put forward higher requirements for the ability and service life of anti-corrosion coatings to withstand the environment. Commonly used anti-corrosion coatings can no longer meet these needs. In recent years, many new anti-corrosion coatings, such as chlorosulfonated polyethylene and chlorinated rubber, have been developed for the heavy-duty corrosion of large-scale equipment at home and abroad. Although these coatings have their own advantages, they are still closed protective coatings. Once the coating is damaged, the material will be corroded quickly. Moreover, these coatings gener...
