Creep type non-cured rubber asphalt based waterproof coating and preparation method thereof

Abstract

The invention relates to a creep type non-cured rubber asphalt based waterproof coating and a preparation method thereof. According to a formula, the waterproof coating comprises, by weight: 10%-50% of asphalt, 20%-55% of solvent oil, 1%-20% of a polymer modifier, 5%-20% of tackifying resin, and 8%-30% of ordinary gelatine powder. The product involved in the invention can be used individually, and also can be used together with other waterproof coiled materials, and especially can effectively solve the water leakage problem caused by waterproof layer cracking resulted from base layer deformation.

Description

technical field [0001] The invention relates to a creep type non-curing rubber asphalt-based waterproof coating and a preparation method thereof, belonging to the field of chemical building materials. Background technique [0002] At present, in the field of domestic building waterproofing, waterproof coatings and waterproof membranes are usually used alone or in combination. When the solvent of the building waterproof coating is volatilized or chemically cross-linked, the coating solidifies into a coating film to play a waterproof role; while the waterproof membrane covers the base layer to play a waterproof role. According to the survey, domestic architectural waterproof coatings are basically cured. 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 is also destroyed. Or there is only a slight extension, and it does not have the real ability to...

AI Technical Summary

Problems solved by technology

According to the survey, domestic architectural waterproof coatings are basically cured. 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 is also destroyed. or only slight extension without real resistance to base cracking

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.

[0003] However, the existing domestic modified asphalt waterproof coatings are mainly solvent-based and water-emulsion-based. These waterproof coatings are not very satisfactory in terms of mechanical properties, waterproof performance and durability. Brittle cracks and delamination occur, seriously affecting the waterproof performance of buildings

Because the paint contains volatile solvents or moisture, during construction, especially in poorly ventilated kitchens and bathrooms and buildings, one is to prolong the period of construction operations, and the other is to cause health effects on workers
