Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a durable waterproof engineering coating and a preparation method thereof. Background technique [0002] In recent years, China's speed represented by high-speed rail has brought many people a convenient and comfortable life experience. From "four vertical and four horizontal" to "eight vertical and eight horizontal", it has greatly met the growing demand for passenger transportation. The world is no longer far away, and the wonderful world is in front of us. The travel plans of ordinary people suddenly increase. Wherever the high-speed rail goes, it becomes the first choice for tourism. High-speed rail not only accelerates the well-being of the people, but also boosts the development of the local economy. With the rapid development of railway construction, especially the high-speed rail business, the railway system technology is also developing continuously. One of the most im...
