Abstract

The invention relates to mastic fluorine paint and a preparation method of the paint. The paint is prepared from the following raw materials in parts by weight: 30-60 parts of fluororesin, 1-5 parts of propylene glycol, 5-10 parts of glycerol, 1-3 parts of plasticizer, 1-3 parts of defoaming agent, 1-3 parts of anti-settling agent, 1-2 parts of wetting agent, 20-40 parts of water, 1-2 parts of pigment and 0.1-0.5 parts of antirust agent. A coating formed after paint spraying is uniform in thickness, and the surface of a film is smooth and dense and free from cracking and blistering. Furthermore, the baked coating is good in acid resistance and alkali resistance and has excellent corrosion resistance. The paint is applicable to the corrosion resistance of ships, offshore petroleum drillingderricks, immersed parts and steel piles of bridges, equipment in chemical plants and the like and reduces the workload of surface protection maintenance and recoating of above steel structures.

Description

technical field [0001] The invention relates to the technical field of organic fluorine coatings, in particular to a high-build type fluorine coating and a preparation method thereof. Background technique [0002] In social life, metal materials are widely used because of their excellent performance, but metals are susceptible to corrosion due to the influence of the environment, resulting in a decrease in their performance and life. According to relevant statistics, the annual corrosion rate of existing steel and metal equipment in the world is about 10%, and the annual economic loss due to corrosion is about 700 billion to 1 trillion US dollars, which is about the sum of economic losses caused by natural disasters such as earthquakes, floods, and typhoons. 6 times, accounting for 2% to 4% of the gross national product (GDP) of each country. According to the authoritative data provided by the Chinese Academy of Engineering consulting project "China Corrosion Investigation ...
