SU956524A1 - Composition for waterproofing coatings - Google Patents

Description

The invention relates to waterproofing materials used in construction, primarily for the construction of soft and suited roofs. A known composition comprising a filler, a heavy pyrolysis resin, sub-standard butyl rubber, a solvent, sub-standard dichloropropane and sub-standard trichloropropane 1. However, coatings based on this composition have insufficient strength. The closest in technical essence and the achieved result to the invention is a composition for waterproofing coatings, including bitumen, varnish kukersol rubber component in the form of a 25% aqueous solution of UMC-50 mastic in gasoline, asbestos and andesite flour 2. Coatings based on this composition do not have a high softening temperature, however, they have insufficient tensile strength and low water resistance and frost resistance. The purpose of the invention is to increase the water resistance, tensile strength and frost resistance of the coating. This goal is achieved by the fact that a composition for waterproofing coatings, including bitumen, varnish, kukersol, rubber-containing component, asbestos and andesitic flour 5, contains 20% butyl rubber in white spirit as a rubber-containing component | ethane, including, may. %: tolylnaftiJ letan 0.5-5; dinaphthylmethane 10-25; Dixilylnaphthalene 10-20 and triaryl and methane - the rest, with the following correlation of components, May.%: Varnish kukersol 20% solution of butyl rubber in white spirit 12-15 Asbestos 4-7 Andesite flour 3-5 Vat residues of production of tolyl naphthylmethane 3-6 V the compositions use bottoms from the production of tolylnaphthylmethane from waste from the production of pyrolysis resins of petrochemical plants.

Examples of a specific implementation of the proposed position are presented in the table.
