Abstract

The invention discloses a wear-resistant and anticorrosive polyethersulfone coating, and a preparation method and an application thereof, and belongs to the technical field of coatings. The purpose of the invention is to solve the disadvantages of needing of cooperative use of multilayer coatings, tedious spraying process, unable consideration to the anticorrosion performance and the wear resistance, and obvious reduction of the anticorrosion and the wear resistance performances at a high temperature of present anticorrosive and wear-resistant coatings. The wear-resistant and anticorrosive polyethersulfone coating is prepared from polyethersulfone resin, polytetrafluoroethylene resin micro-powder, silicon carbide micro-powder and a composite solvent, and synergism of above components makes a coating layer obtained by using the coating has no change and maintains adhesion after being immersed in 10% sulfuric acid or 10% sodium hydroxide or toluene for 120h; and the friction coefficient and the wear rate of the coating layer are extremely low, so metal corrosion is effectively avoided, and difficult wearing failure of the coating layer is realized.

Description

technical field [0001] The invention belongs to the technical field of coatings. Background technique [0002] There are three main forms of failure of mechanical parts in modern industry, namely wear, fracture, and corrosion. Corrosion pervades all sectors of the national economy and brings huge economic losses to the national economy. With the process of industrialization, the corrosion problem is becoming more and more serious. The iron and steel equipment scrapped due to corrosion is equivalent to 30% of the annual output in the world every year. The annual economic loss caused by corrosion in developed countries accounts for about 2-4% of the gross national product; the United States consumes 3.4% more energy due to corrosion every year; the economic loss caused by corrosion in my country every year is at least 20 billion. The great harm of corrosion is not only reflected in economic losses, it will also bring heavy casualties, environmental pollution, waste of resou...
