Description

technical field [0001] The invention belongs to the technical field of asphalt waterproof paint, and relates to a highly cross-linked asphalt waterproof water-based paint. Background technique [0002] In the current civil engineering industry, building waterproofing has become the focus of attention, and people's property and life safety are seriously endangered due to the leakage of buildings and structures. Therefore, the research and development of new waterproof materials and the improvement of waterproof material performance have become the current The focus of research, of which bitumen-based waterproof coating is one of them. At present, modifying asphalt with modifiers has become one of the most effective ways to improve the performance of asphalt-based waterproof materials, and then it is prepared through a special process. [0003] Existing sprayed asphalt waterproof coatings have problems such as easy cracking of the coating film, weak adhesion, short service li...
