Problems solved by technology

Patent CN107629653A discloses an outer protective coating for crawler tracks, which can greatly improve the wear resistance of track tracks, but its hydrophobicity is not very good, and the tri-n-butylamine used in it is highly toxic, which brings inconvenience to the preparation. bad impact on the environment
In order to improve the hydrophobicity of coatings, some researchers use fluorine-containing substances to reduce the surface energy of materials, but fluorine-containing substances are expensive and have certain harm to the environment, or use fluorine-free polymer coatings containing silicon-oxygen bonds , but there are certain problems in its binding force, and it is easy to peel off during exercise

Abstract

The invention discloses a wear-resistant anti-corrosion coating for underwater robot track protection and a preparation method of the wear-resistant anti-corrosion coating. The wear-resistant anti-corrosion coating is prepared from the following components in parts by mass: 120 parts of ethanol, 80 to 100 parts of polyurethane, 8 to 12 parts of dopamine, 10 to 20 parts of micron zinc oxide, 6 to 10 parts of nano silicon dioxide, 1.5 to 3.0 parts of stearic acid, 1 to 3 parts of gamma-aminopropyltriethoxysilane, 1 to 2 parts of zinc stearate, 0.3 to 0.8 part of an antioxidant, 0.3 to 0.5 part of ethyl lauroyl arginate hydrochloride and 0.5 to 1.5 parts of polyvinylpyrrolidone.

Description

technical field [0001] The invention relates to the field of superhydrophobic coating materials, in particular to a wear-resistant and anti-corrosion coating for underwater robot crawler protection and a preparation method thereof. Background technique [0002] With the needs of the development of human society and the progress of science and technology, the scale of underwater engineering is getting larger and larger, and more and more needs to be used in the investigation and detection of underwater resources, rescue and lifesaving, ocean development, and hull surface cleaning operations. to underwater robots. Underwater robots work underwater for a long time, and the relevant components will be eroded by seawater / sewage. The salt in seawater will accelerate the aging or corrosion of the crawler tracks. Clean the crawler tracks in time after use in such an environment; It will rub against sand, gravel, mud or other foreign objects in water to cause wear. In order to mini...
