The Preparation and Application of High Strength of Polyurethane Waterproof Coating
Abstract: According to China's express passenger railway line and green roof building needs and long-term development plan, high-strength polyurethane waterproof coating is expected to be widely used in these areas. This paper studied the preparation of high-strength polyurethane waterproof coating, high-speed railway to be met the requirements of special waterproof coating, and try to apply it to the roof planting waterproof layer. At the same time, we also do the research about the materials’ Puncture resistant study and study on resistance to plant roots puncture accelerate Exploration. The results showed that the coatings tensile strength increase, the puncture resistance capability will also increase. Results are very meaningful.
