Description

technical field

[0001] The invention relates to the technical field of automobile coatings, in particular to a water-based antirust primer. Background technique

[0002] Over the past 30 years, my country's automobile industry has developed rapidly, especially in the last 20 years, the automobile industry has shown a blowout rapid growth. In 2009, the total output of automobiles nationwide reached 13.79 million, and the number of automobiles has reached 76.19 million. The great development of the automobile industry has also led to the development of automobile coating technology. At the same time, automobile coatings have also made great progress.

[0003] At present, my country's automotive coatings are still dominated by solvent-based systems, which contain a large amount of volatile organic compounds (VOC), which pollute the environment very seriously. Since the 1960s, in order to protect the living environment of human beings, countries around the world have enacted r...
