SBR - SBR modified acryl-urethane waterproof composition including water-soluble urethane polymer and preparation method thereof

摘要

The present invention relates to a waterproof composition including a styrene butadiene rubber (SBR) modified acryl-urethane resin containing an urethane polymer and nano sulfur particles having surfaces modified to be hydrophilic, wherein the waterproof composition of the present invention is not easily damaged by temperature change or vibration, can effectively prevent water or salt from penetrating into a building, is environmentally-friendly as an organic solvent is not used and has excellent durability, stretchability and adhesion to a substrate.
