Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high and low temperature resistant coating. Background technique [0002] Traditional coatings use organic substances as solvents, which will release volatile organic substances during processing and production, which will pollute the environment. Water-based coatings use water as a solvent, and are environmentally friendly, energy-saving, safe, and easy to use, and have developed rapidly in various countries. However, with the rapid development of industry, people have higher and higher requirements for the performance of water-based coatings. The high and low temperature resistance of water-based coatings can no longer meet the needs of industrial development, so a new coating needs to be provided. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a high and low temperature resistant coating, wh...
