IMPROVED ASPHALT WATERPROOF SHEETS

摘要

A rubber asphalt waterproof sheet for composite waterproofing is provided to make a film waterproofing layer uniform and to maximize waterproofing performance by forming a perfect double-composite waterproofing layer. The rubber asphalt waterproof sheet(S) for composite waterproofing is composed of a rubber asphalt layer(20); a synthetic resin film(30) attached on the rubber asphalt layer; a first primer coating layer(40) formed on the synthetic resin film; and a fiber cloth attached under the synthetic resin film and a second primer coating layer formed under the fiber cloth, which are stacked between the rubber asphalt layer and the synthetic resin film. Primer forming the first and second primer coating layers consists of main materials and a hardening agent. The main material consists of polyolefin chloride of 10~20wt.% and a solvent of 80~90wt.%. The hardening agent is made of polyisocyanate of 100wt.%.
