The adhesion-intensified waterproofing sheet of recycled poly-vinyl chloride and the composite waterproofing construction method using this waterproofing sheets

摘要

PURPOSE: A recycled poly(vinyl chloride) waterproof sheet and a complex waterproof technique using the sheet are provided, to improve the adhesive strength and the construction convenience. CONSTITUTION: The recycled poly(vinyl chloride) waterproof sheet comprises 70-80 wt% of the waste poly(vinyl chloride) resin; 10-14 wt% of a recycled resin obtained by recycling the waste vinyl acetate copolymer adhesive film scrap; 5-8 wt% of a recycled resin obtained by recycling the waste vinyl acetate copolymer adhesive; and 5-8 wt% of powdered stone. The complex waterproof technique comprises the steps of coating the surface of concrete(1) to be repaired with an adhesive, and covering the recycled poly(vinyl chloride) waterproof sheet(10) on the surface; coating an acryl acetate-based coating waterproof agent(20) onto the sheet(10) one or two times; and coating the surface with a top coating protection finishing material(21).
