Problems solved by technology

At present, there are not many studies on water-based non-curing. Among them, in the water-based non-curing rubber asphalt coating and its preparation method disclosed in CN105038593A, cationic rubber modified emulsified asphalt is compounded with other additives such as tackifying resin emulsion, but cationic The preparation of rubber-modified emulsified asphalt requires deionized water, and the storage performance is poor. In addition, the solvent ethyl acetate is needed in the preparation process of the tackifying resin emulsion, which needs to be removed after it is made. The process is complicated and it is not conducive to environmental protection requirements.

Description

technical field [0001] The invention relates to the technical field of anionic water-based non-curing rubber asphalt waterproof coating. Background technique [0002] Non-curing rubber asphalt waterproof coating is a waterproof coating that maintains a viscous paste within the service life and is made by mixing rubber and asphalt as the main components with additives. Because of its good adhesion, extensibility, low temperature flexibility and creep self-healing properties, it is a new type of waterproof material that has developed rapidly in the past ten years. Non-curing rubber asphalt waterproof coating is famous for its high solid content. The coating itself has environmental protection performance, but its construction process needs to be heated to about 180 ℃ to flow, before it can be sprayed or brushed, which will cause certain construction inconvenience and smoke. Environmental pollution is also harmful to the health of construction workers. In the prior art, non-c...
