Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an acid-resistant coating for wooden ancient buildings in a heavy industrial environment, a preparation method for the acid-resistant coating for ancient wooden buildings in a heavy industrial environment, and an application method for the acid-resistant coating for ancient wooden buildings in a heavy industrial environment. Background technique [0002] In recent years, the harm of climate change and environmental change to ancient buildings has attracted more and more attention of cultural relic experts. With the development of human industrial activities, there are more and more acidic substances such as carbon dioxide, hydrogen sulfide, and sulfur dioxide in the atmosphere. These substances fall to the ground with rainwater, causing serious acid rain pollution. And acid rain is obviously harmful to ancient buildings. As the global climate warms, the temperature ...
