Since 1949, marine coatings and their coatings have made great development and innovation. By 1995, with the use of sand blasting in surface treatment and the appearance of etching primer and ethylene primer, the service life of the ship has been extended to l.5-2.0 times. The red lead coating or zinc chromate coating is used as the base coat and the oil-soluble phenolic resin coating containing cuprous oxide is used as the top coat, which greatly improves the defects of foaming and peeling of the coating. 1954 entered the shipbuilding boom for the first time, which was the result of the development of long-term exposure of primer and sandblasting treatment on the steel surface, and further, it was the result of adopting some shipbuilding methods for the first time in the world. From 65438 to 0960, due to the appearance of zinc-rich epoxy coatings and the development of epoxy asphalt coatings, it turned to thick film long-term anti-corrosion system. In the following three years, it entered the second shipbuilding boom, and epoxy asphalt replaced oily coatings and chlorinated rubber coatings for rust prevention, accounting for more than half. 1967, with the appearance of inorganic zinc-rich workshop primer, the ship became larger, the construction efficiency was improved, and the corresponding heavy-duty anti-corrosion methods became the mainstream. 1975, in order to improve production efficiency, the research and development of coatings entered fierce competition, and low-concentration inorganic zinc-rich workshop primer appeared. One year later, the copolymer of tributyl methacrylate (TBT) antifouling paint was put into practical use, and the construction of cargo ships increased rapidly. From 65438 to 0982, due to marine pollution, the United States, Britain and Japan restricted the use of "TBI" on a global scale. The second specific form of tributyltin compound produced in Japan in 1990 is also restricted. As a result, Wuxi antifouling paint appeared. In 1993, IMO stipulates that in order to prevent oil leakage, oil tankers should have double hulls. The double-shell ballast tank adopts epoxy asphalt coating, but the modified epoxy coating still attracts attention from the aspects of safety, sanitary performance, working environment of local coating and inspection efficiency of oil tank coating.

The marine coatings in China are accompanied by the rise of shipbuilding industry in China. In 1980s, as the world shipbuilding industry moved to East Asia, China shipbuilding industry gradually became an important part of industrial manufacturing industry, and formed the industrial layout around Bohai Sea, Pearl River Delta and Yangtze River Delta. With the rapid growth of shipbuilding industry, the output of marine coatings has reached 673,000 tons in 2005, which is about 265,438 tons in China.

At present, there is still a big gap between China's ship painting technology and foreign countries, which is manifested in the long painting cycle, low efficiency and high cost. The main reasons are: the design depth of ship painting production is not enough, and the concept of shell painting integration is not strong; The degree of mechanization and automation of ship painting process equipment is not high, which leads to high standards of derusting and painting and serious problems in implementation; Pretreatment quality and shop primer performance need to be improved; The management of ship production needs to be strengthened urgently, and the problem of repeated painting is very serious because of the damage of other types of construction to the coating film.
