Abstract

The hydro-insulation material includes hard hydraulic connecting substances, fillers, modificators and liquid hydrophobic additives on the basis of synthetic and/or natural macro-molecular materials and water, where the hard part of the connecting hydraulic substances consist of weight part of cement and/or gypsum from 30.0 to 60.0; a filler - a quartz sand, basalt fibres, microasbestos, timber andesite, limestone, dolomite from 35.0 to 65.0; from 2.0 to 4.- modificators, which are derivatives of the cellulose, mainly hydroxyethylcellulose, methylcellulose, carboxymethylcellulose, methylhydroxipropylcellulose, acetylcellulose and alcalcellulose and/or acid casein; 0.5-3.0 siloxide and/or calcium stearate. Each 100-weight part of rigid substance contain between 10.0 to 60.0 weight part of liquid hydrophobic component consisting of water dispersion of at least one co-polymer forming at co-polymerization of the vinylchloride with vinylacetate, ethylacrylate, buthilakrilate, 2-ethylhexiacrylate, acryl acid, mono-N-butilmalleinate, N-butyl-malonate, malleinate anhydride or malleine acid, stirol and 1.3 butadien with content of between 50 to 90 weight part., primarily between 60 to 82 weight part of co-polymerized vinylchloride with a dry residue of between 30 to 52% weight parts.
