Problems solved by technology

[0006] However, in the northeastern region at high latitudes, the winter is cold and long, and some areas are in the cold temperate zone. At present, there is no building waterproof material in the national standard that can effectively resist the influence of external stress in the environment of -30 ~ -40 ° C. Therefore, a A kind of polymer emulsion modified asphalt waterproof coating that can also be applied in cold regions is of great significance

Abstract

The invention discloses a water-based permeable self-healing high polymer modified asphalt waterproof coating with a hydrophobic surface as well as a preparation method and application thereof. The coating is prepared from emulsified asphalt, acrylate emulsion, an alkali swelling thickener, a polyurethane thickener, a dispersing agent, a multifunctional additive, a defoaming agent, a sterilizing agent, ground calcium carbonate powder, bentonite, an organic silicon water repellent, sodium silicate, a photoinitiator, a cross-linking agent and water. The coating disclosed by the invention mainlyhas rapid curing performance, self-healing performance, ultrahigh bonding strength and elongation rate and excellent water resistance and high and low temperature resistance, is suitable for various environments, can achieve a good waterproof effect on a building structure in any environment, is particularly suitable for waterproof engineering of various extremely complex environments, projects ofsome complex scenes and some special regions and projects, fills the blank of the material in severe cold regions, and is wide in application range.

Description

technical field [0001] The invention relates to a waterproof material for construction, in particular to a water-based permeable self-healing high polymer modified asphalt waterproof coating with a hydrophobic surface and a preparation method and application thereof. 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. At the same time, for modified asphalt technol...
