Abstract

The invention discloses a rubber modified asphalt waterproof coating material, which is prepared by mixing the following components: asphalt, rubber, an asphalt regenerant, an emulsifier, a stabilizer, water and other auxiliary agents. The invention further discloses a preparation method and applications of the rubber modified asphalt waterproof coating material. According to the present invention, in the rubber modified asphalt waterproof coating material preparation process, by using the asphalt regenerant, the added rubber can be fully fused with the asphalt, such that the modified asphaltwith high rubber content cannot segregate, and the asphalt regenerant can greatly reduce the high-temperature viscosity of the modified asphalt so as to reduce the emulsification difficulty of the modified asphalt with high rubber content; by using the preparation process comprising secondary pH value adjustment, the high solid content emulsified product can be prepared in the case of the low emulsifier adding amount; and by adding the stabilizer to the product of the invention, the occurrence of demulsification can be avoided so as to ensure the storage stability of the product at a later stage.

Description

technical field

[0001] The invention relates to the technical field of asphalt processing, in particular to a rubber-modified asphalt waterproof coating, its preparation method and application. Background technique

[0002] At present, the main waterproof coatings widely used in my country's building waterproofing projects include: polyurethane waterproof coatings, polymer cement waterproof coatings, acrylic waterproof coatings and water-emulsion asphalt waterproof coatings. These coatings have played a huge role in my country's building waterproofing projects by virtue of their unique material characteristics, such as polyurethane waterproof coatings, which have high strength, high elongation and other characteristics, and can resist stress damage caused by concrete cracking to a certain extent; polymerization Bio-cement waterproof coating, which is both rigid and flexible, and can be applied on a wet base surface. It is widely used in waterproofing of kitchens, bathrooms, b...
