DESCRIPTION OF THE INVENTION

The invention relates to the field of building materials and can be used for gluing various building elements and parts, as well as for gluing tiles, linoleum and other materials.

Known is an adhesive composition comprising a latex of a copolymer of butadiene with acrylonitrile and methacrylic acid, saponified with alkali ( see Russian patent 2,036,945, published June 9, 1995 ).

The closest analogue to the invention is an adhesive , H: isoprene-nitrile latex (dry weight) 90-100, filler 3-60, surfactant 0.3-3, thickener 0.1-2.5, thixotropic additive 0.1-2.5, 20 % Aqueous solution of ammonia or potash 0,1-2,5, water - the rest (see copyright certificate of the USSR No. 729227, published on April 27, 80).

The object of the invention is to increase the adhesion of the adhesive to the surface of the materials to be bonded.

The above object is achieved in that the adhesive for construction works, including synthetic latex, surfactant, thickener, alkali, filler and water, contains as a surfactant the product of treatment of mono- and dialkylphenols with ethylene oxide OP-7 or OP-10 , And as filler - chalk and quartz sand and additionally dispersant, coalescent, biocidal additive, antifreeze, antifoaming agent, plasticizer and antimony trioxide at the following proportions of components, mass%:

  • Synthetic latex - 5-30
  • The surfactant OP-7 or OP-10 is 0.1-1.5
  • Thickener - 0.05-1.5
  • Dispersant 0.1-1.5

  • Antimony trioxide - 3-5
  • Alkali - 0.05-5
  • Sand - 0-25
  • Chalk - 30-70
  • Water - Other

In this case, the glue may additionally contain talc and / or quartz flour.
