In the beginning of the 20 th century, korea-this waterproof material limited invented a hot-melt type non-cured rubberized asphalt waterproof coating, which was heated and scraped/sprayed during construction, and was mainly used for adhering a coil material, and the waterproof effect was good. Since 2010, many domestic large-scale waterproof enterprises begin to develop and produce non-cured asphalt waterproof coatings, and the standards of JG/T2216-2018 'non-cured rubber asphalt waterproof coatings' are implemented, and the coatings are resistant to high temperature of 65 ℃, however, with the application of engineering, the use of the coatings is found to be limited. For example, the heating construction smoke is heavy, pollutes the environment and damages the physical and psychological health; the high temperature resistance is low, the flow of the vertical surface and the inclined surface is serious, and the attached layer on the upper surface collapses particularly in a high-temperature environment.
In order to make the material highly bright, the material continues to serve as building waterproofing. Provides a high-temperature non-curing rubber asphalt waterproof coating.
