Problems solved by technology

However, many advantages of polymer cement waterproof coatings (also known as JS coatings) have not been fully discovered, especially how to make it better waterproof and widely used in the waterproof and corrosion resistance of metal pipelines in underground engineering construction. It has been truly solved. The currently commercially available JS coatings have a large poly-ash ratio (large amount of polymer), limited elongation rate, poor water resistance, high water absorption rate, and obvious softening strength after long-term immersion. Solve the problem of polymer cement waterproof coatings ( Also known as JS paint) to play a better role in waterproofing and widely used in underground engineering construction waterproof and corrosion resistance is a very important issue

Description

technical field [0001] The invention relates to a polymer cement waterproof coating, in particular to a polymer cement waterproof coating composition for underground engineering pipelines. Background technique [0002] With the rapid development of the national economy, my country's underground engineering construction is also booming, especially oil pipelines, gas pipelines, underground tunnels, subways and urban construction are currently at the forefront of the world. In the great development of underground engineering construction, how to do a good job of waterproofing and corrosion resistance of underground engineering pipelines is the most concerned issue for engineering construction parties. To overcome technical difficulties, we must rely on scientific and technological progress and adopt advanced technologies, including the application of new materials. In recent years, polymer cement waterproof coating (also called JS coating), which has developed rapidly, has been...
