HYDROINSULATING MATERIAL WITH INCREASED FROST RESISTANCE

摘要

The invention concerns a hydro-insulating material with increased frost resistance designed for hydro-insulation of roof coverings and similar purposes. The material consists of 120 to 180 mass parts of waste pitch from the production of dimethyl terephthalate containing 70 to 75 % by weight carbon, 20 to 25 % by weight hydrogen and 20 to 25 % by weight oxygen, 1 to 15 mass parts dibutylphthalate, 35 to 50 mass parts copolymer vinylchloride-vinylacetate with content of 8 to 30 % by weight vinylacetate, 7 to 15 mass parts stabiliser, particularly aluminium dust, 70 to 150 mass parts solvent, particularly toluene, acetone, or their combination and 2 to 10 mass parts rubber coagulate or un-catalysed viscous rubber.
