Saline-alkaline resistant spray fast-setting rubber asphalt waterproof material

Abstract

The invention relates to a saline-alkaline resistant spray fast-setting rubber asphalt waterproof material which is a water-based spray coating prepared proportionally by preparing liquid rubber asphalt mastic latex from modified emulsified asphalt and high-molecular polymer rubber latex and mixing with a coagulating agent. Compared with the traditional coiled material, the saline-alkaline resistant spray fast-setting rubber asphalt waterproof material provided by the invention has the advantages of cold construction, fast film forming, strong saline-alkaline resistance and high recovery rate, wherein the operation is safe and reliable by mainly adopting a mechanical coating way; a film can be formed in 30 seconds after spraying; the formed elastic film has high elongation (greater than 1,000%), high bonding strength (greater than 0.5Mp) and good low-temperature flexibility (without breakage at -20 DEG C); experiments show that the elastic film after saline-alkaline treatment still has good elongation at break (greater than 800%) and low-temperature flexibility (without breakage at -20 DEG C); and the recovery rate is greater than 90%, thus the material provided by the invention has certain self-repairing ability and can realize self repairing of tiny cracks.

Description

technical field [0001] The invention relates to a waterproof paint, in particular to a saline-alkali-resistant spray-coated quick-setting rubber asphalt waterproof material. technical background [0002] Buildings in eastern coastal areas and other areas with high salinity are easily corroded due to long-term high-saline environment. Traditional waterproof materials have poor acid and alkali resistance, which greatly shortens their service life and are easily damaged and lose their waterproof effect. . In addition, it is very difficult to replace general building waterproof materials, so buildings in high-saline-alkaline areas have higher requirements for waterproof materials to withstand salt and alkali. Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the present invention provides a salt-alkali-resistant spray-coated quick-setting rubber asphalt waterproof material with outstanding saline-alkali resistance and long service l...

Problems solved by technology

[0002] Buildings in eastern coastal areas and other areas with high salinity are easily corroded due to long-term high-saline environment. Traditional waterproof materials have poor acid and alkali resistance, which greatly shortens their service life and are easily damaged and lose their waterproof effect.

In addition, it is very difficult to replace general building waterproof materials, so buildings in high-saline-alkaline areas have higher requirements for waterproof materials to withstand salt and alkali.
