FIELD: production of water-proofing roll coverings.
SUBSTANCE: covering is made from polymer-bitumen composition based on chlorosulfurized polyethylene "Anticor", rubber sublayer "Unichrom" based on rubbers, and polyamide fabric. Polymer-bitumen composition contains chlorinated polyethylene as modifying additive with chlorine content of 40 wt%. Covering is additionally provided with protective layers of plasticized polyvinyl chloride and corrosion-resistant enamel based on chlorosulfurized polyethylene. Covering has increased elasticity (elongation at rupture), tensile strength and frost resistance while main operating properties (thermal resistance and water absorption) are kept.
EFFECT: improved properties of roll covering.
