However, the leakage problem of the building engineering, especially the leakage problem of the roof, is high for a long time, and causes great loss and unnecessary trouble to the national property and the life of people. According to the survey of the national institute of building and waterproof industry, 65% of new houses in China can leak in different degrees within one to two years at present, and 65% of building and waterproof projects need to be renovated after 6 to 8 years. Building leakage has become the second major building problem outside of the structure, and has long plagued the broad masses of developers and people.
At present, no waterproof material specially used for roof repair exists in the market, various waterproof coatings, sealing materials or grouting materials are used for replacing the waterproof material, and hot melt asphalt is even directly used as a repair material for some waterproof materials, so that the waterproof materials cannot meet the requirements of a roof repair agent in the aspects of construction performance, application performance and aging resistance. Particularly, in the rainy environment in the south, the roof is in the leakage problem under the conditions of extreme humidity, open water and even rain for a long time, and no roof repairing material suitable for open water construction exists in the market. Therefore, aiming at the leakage problem of the building roof, the development of the open water construction modified asphalt roof repairing agent which has strong permeability, good bonding property to the base layer, good construction performance and good adaptation to the base layer, can be applied to most of base layers (cement, concrete, high polymers, metals and the like) and harsh use conditions (in the rain process or in the open water base layer), has good aging resistance and can be applied to the roof repairing material in the exposed environment is urgently needed.
