FIELD: chemistry.SUBSTANCE: invention relates to field of obtaining glue compositions, used for production of adhesive polyvinylchloride (PVC) tapes, intended for insulation and protective coating of gas and oil pipelines. Glue composition for adhesive polyvinylchloride tapes contains perchlorovinyl resin, chloroparaffin CP-470 or chlorinated ?-olefins, rosin, chalk or milled marble and additionally contains plasticiser DES, basically representing modified mixture of high-boiling ethers of dioxane alcohols (4-methyl-1,3 dioxane-4ethanol) with addition of stabilisers.EFFECT: application of invention makes it possible to increase glue stickiness, reduce area of coating detachment in cathode polarisation at temperature 20°C, cost of polymer material and extend raw material base of plasticisers.10 ex, 1 tbl |
