Non-solidifying rubber asphalt building waterproof coating

Abstract

The invention discloses a non-solidifying (wriggling) rubber asphalt building waterproof coating and belongs to the field of chemical material building. The coating is prepared by processing the following raw materials: 50-400 parts of regenerated rubber powder, 100-600 parts of 10# asphalt, 50-300 parts of regenerated lubricating grease, 10-200 parts of regenerated flora and fauna grease, 50-300 parts of tertiary-distilled oil, 10-100 parts of polypropylene resin, 10-100 parts of polyamide (PA-12) resin, 10-500 parts of styrene butadiene styrene (SBS), 10-100 parts of coumarone resin, 10-100 parts of carbon 5 resin, 10-100 parts of polypropylene wax, 10-100 parts of paraffin base rubber oil, 10-100 parts of oleamide, 10-100 parts of attapulgite powder, 10-100 parts of smectite and 1 part to 20 parts of silicone oil defoamer. Inspections show that technical indexes of the non-solidifying (wriggling) rubber asphalt building waterproof coating are superior to JC / T864-2008 national material building industry standard of the 'polymer emulsion building waterproof coating', and stability and aging resistance of the coating are greatly improved.

Description

technical field [0001] The invention relates to chemical building materials. Specifically, it is a non-curing (creeping) rubber asphalt waterproof coating for buildings. Background technique [0002] Leakage of building structures has been a problem that has plagued the construction industry for a long time. According to statistics from relevant departments, more than half of the complaints about project quality are about building leakage. Therefore, building waterproof technology and waterproof materials have always been an important topic for researchers to study. [0003] At present, the waterproof construction design of domestic building waterproofing projects usually uses waterproof coatings and waterproof membranes alone or in combination. Architectural waterproof coatings are divided into solvent-based and water-based types according to the type of medium. When the medium volatilizes, the coating solidifies into a coating film to play a waterproof role; while the wa...

AI Technical Summary

Problems solved by technology

At present, the architectural waterproof coatings disclosed in China are all curing types. Although they have certain waterproof performance and bonding strength, their tear resistance is poor. When cracks appear in the base layer of the coated object, the coating film will also be destroyed, or Only a small extension, but no real ability to resist cracking of the base layer (the concept of "zero extension" has been recognized in the industry)

Once the coated base layer is deformed and cracked, it will cause the coating film to crack and lose its waterproof function; and the construction of waterproof membranes has many overlapping seams, which can easily cause the seams to bulge and cause water to leak; the second is waterproof rolls Although the material has a certain extension performance, but the base layer under construction has cracks or the building structure is deformed, the only small extension of the waterproof membrane does not have the ability to resist cracking of the base layer, so that the membrane cracks and loses its waterproof effect.
