Material for forming waterproof coating film

Abstract

Abstract PURPOSE: To prepare a material for forming waterproof coating film having improved adhesivity, waterproofness, chemical resistance, etc., by adding a specific amount of an ethylene-vinyl acetate copolymer emulsion containing a water-soluble polymer such as PVA as emulsifier to granulated slag or Portland blast furnace cement composition. CONSTITUTION: The objective film-forming material is prepared by adding an ethylene-vinyl acetate copolymer resin emulsion having the vinyl acetate content of 60W90wt% to granulated slag composition or Portland blast furnace cement composition using a water-soluble polymer such as polyvinyl alcohol, a cellulose derivative, etc. as an emulsifier. The amount of the resin emulsion is 40W200wt% (solid basis) of the cement. COPYRIGHT: (C)1981,JPO&Japio
