Document Type and Number:
WIPO Patent Application WO/2020/054968
Kind Code:
A1
Abstract:
The present invention relates to a highly elastic inorganic filler for repairing and reinforcing a cracked region and a method for repairing and reinforcing a cracked region by using same, wherein the highly elastic inorganic filler can be efficiently used especially in a cracked region mainly generated on a building wall surface or a road surface, and can be used to form a waterproofing coating at the time of painting concrete building exterior walls to thereby make it possible to provide a clean appearance in cases of exterior painting and avoid as much as possible the inconvenience of frequent repairs. The reinforcement of the cracked region is attained by not only selectively employing a reinforcing unit provided in the present application but also applying, to the cracked region, a highly elastic inorganic filler formed by mixing: any one powder selected from a stone powder, a calcium carbonate powder, Portland cement, calcium sulfoaluminate-based cement, and blast furnace cement, which have a particle size of 100-200 mesh; a main material part resulting from the mixing of 45-55 wt% of ethylene vinyl acetate, 20-30 wt% of a diluent, 15-25 wt% of distilled water, 1-5 wt% of polyurethane, 1-5 wt% of rosin or rosin ester, and 0.05-0.3 wt% of a pH adjuster; and a setting accelerator, at a weight ratio of 1:0.4-0.6: 0.1-0.2.
