▎ 摘  要

NOVELTY - Waterproofing composition comprises 27-33 wt.% water-soluble acrylic silicone resin, 1-2 wt.% a thickener, 1-2 wt.% emulsifier, 1-2 wt.% silica and water-soluble acrylic resin (balance). The composition further comprises 1-2 wt.% duck feather powder and 1-2 wt.% conductive fibers. The conductive fiber is a copper conductive acrylic short fiber in which copper ions generated from copper sulfide are bonded to an acrylic fiber. USE - The composition is useful for civil structures e.g. roof of a concrete building, top of the underground parking lot, outer wall of the basement, underground tarin, underpass, and common ward. ADVANTAGE - The composition: has high adhesion performance and tensile performance; prevents degradation of construction and cracking; improves waterproofness by coping with other construction defects in buildings; solves the problem of destruction of chemical bonds caused by ultraviolet rays and moisture; has excellent weather resistance; and prevents external shocks.
