METHOD OF PRODUCING THE THERMOSHRINKAGING ADHESION MATERIAL Russian patent published in 1997 - IPC

FIELD: polymers. SUBSTANCE: invention relates to producing thermoshrinkaging adhesion material based on extruded and electron-chemically modified polyethylene or ethylene copolymer. Method involves applying adhesion composition containing rubber with polar groups, highly viscous bitumen and special addition on the modified and directed polyethylene or ethylene copolymer. Extruded band is subjected for calendering to make one of its surface as chamois-like form followed by electron-chemical modification up to the absorbed dose 0.15-0.35 MGr, directed by 30-50%. Then adhesion coating based on composition containing additionally filling agent, anticorrosion, fungicide and bactericide additions is applied. EFFECT: improved method of producing. 1 tbl
