Waterproofing compound and construction method using the compound

Abstract

The invention provides a waterproof composition and configuration and construction method thereof. The waterproof composition is an asphalt waterproof composition using liquid rubber, having high restoring force, cold resistance and adhesiveness. Based on 100 parts of neoprene latex by weight, 100 parts of neoprene latex, 160 to 240 parts of oil-extended styrene buadiene rubber, 160 to 240 parts of carboxylic styrene butadiene rubber, 90 to 1600 parts of emulsified asphalt and 2 to 100 parts of additive by weight are mixed so as to provide the waterproof composition with the pH value of 7 to 12.

Description

Technical field [0001] The present invention provides a bituminous waterproof compound, and more specifically, it provides a method that utilizes Chloroprene Rubber latex (CR), oil-extended styrene butadiene rubber (SBR), Carboxylated Styrene Butadiene Rubber; XSBR) and emulsified asphalt bitumen waterproof compound. Background technique [0002] Water proofing compound (water proofing compound) generally refers to a composition that uses the film left after the water or solvent of the water-coated or oily waterproofing liquid on the building and structural walls to evaporate water or solvent to obtain a waterproof effect, and the above-mentioned waterproof compound is usually It is waterproof and used on the roof and outside of buildings and civil engineering structures, the walls and roofs of underground structures, toilets, bathrooms, and balconies. [0003] At present, the most popular waterproof compounds include emulsion waterproof compounds with rubber asphalt, acrylic rub...

AI Technical Summary

Problems solved by technology

[0005] As mentioned above, rubber bitumen waterproofing compounds have the advantages of high elongation, crack resistance, cold resistance and jointability, but also have the disadvantages of low recovery force, chemical resistance, ozone resistance and UV resistance

[0006] In particular, since the recovery force of the water-repellent compound mainly composed of oil-extended jasmine rubber is too low, if the above-mentioned water-repellent compound is stretched repeatedly, thermalization may occur to cause the consequence that the above-mentioned water-repellent compound loses its physical properties, and also will lead to deterioration of its quality

Also, the waterproof compound mainly composed of oil-extended jasmine rubber has low chemical resistance, ozone resistance and ultraviolet resistance, so if the above waterproof compound is exposed to chemical substances and ozone or ultraviolet rays for a long time, it will quickly leads to quality deterioration

[0007] On the contrary, the waterproof compound with neoprene latex as the main component has low cold resistance, so the above-mentioned waterproof compound cannot adapt to the surrounding environmental changes in time and effectively.

[0008] In order to improve the above problems, although some countermeasures have been suggested, these countermeasures are still not enough for the surrounding environmental changes and are not good for the life of the waterproofing agent. Can meet the requirements, so a kind of new technology that can overcome the above problems is urgently needed in this technical field
