Title:
WATERPROOF MATERIAL
Document Type and Number:
WIPO Patent Application WO/2017/092570
Kind Code:
A1
Abstract:
A waterproof material (100) comprises a sequentially configured waterproof substrate (110), pressure sensitive adhesive layer (120), and protection layer (130) formed by curing a permeation resistant coating. The protection layer (130) comprises an organic substrate (131) and inorganic fillings (133) and inorganic particles (132) spread in the organic substrate (131). A part of the inorganic particles (132) protrude outside a surface of the pressure sensitive adhesive layer (120) facing away from the organic substrate (131). The permeation resistant coating comprises the following components in percentage by mass: 5-50% of polymer emulsion, 5-15% of inorganic fillings, 20-70% of inorganic particles, 0-10% of a wetting agent, 10-50% of water, 0-5% of a dispersant, 0-5% of antifoam, 0-5% of a thickening agent, and 0-5% of additives. The waterproof material can combine with a concrete structure, and provide favorable weather resistance.
