Abstract

The invention relates to polymeric solutions, which can be used for waterproofing and as an adhesive, for example, for gluing ceramic tiles to concrete in conditions of high humidity. Polymer solution has high adhesion to wet concrete and ceramics, is characterized by rapid recruitment, strength and low toxicity. The polymer solution contains, May 4.: 1 polyisocyanate lOOj bottoms distillation of the production of glycerin 20-30; epoxy resin 8-12; triethylenetetramine 0.08-0.12; port (Landland 230-270; quartz sand 230-270.

4;: CO I 1 The invention relates to a construction solution containing an organic and inorganic binder. The purpose of the invention is to improve the strength of the polymer solution with from 5 wet concrete and ceramics under freezing and thawing conditions. Full solutions, which are listed in the table, are prepared in 3 solution under stirring of overdosed amounts of components; For the preparation of the compositions, a polyisocyanate is used - a derivative of diphenyl diisocyanate containing 4560% of individual diphenyldiisocyanate and 29.5-30% of free ESH-isocyanate groups, epoxy CMDjry ria based on diphenylolpropane containing 2 3-13.5% of epoxy groups ethylene-amide groups, VAT residues from the stage of the dissociation of glycerol production contain ii,%: NaCl not more than 10; water not more than AO; derivatives of glycerol to 50 (glycerin 0, diglyp, erik 70-80; tetraglycerol 5-10; pentagl; P; erin 5). The compositions of polymeric solutions are characterized by the properties listed in Table 2.
