ADHESIVE COMPOSITION FOR ADHESIVE TAPES Russian patent published in 2008 - IPC C09J127/22 C09J7/00 

Abstract RU 2334775 C1

FIELD: chemistry.

SUBSTANCE: invention refers to production of adhesive compositions used for adhesive polyvinylchloride (PVC) tapes applied to various surfaces. Invention can be used for production of polyvinylchloride adhesive tape intended for gas and oil pipelines wrapping as insulating and protecting coating, as well as for repair works. Technical result of invention is higher adhesion capacity of adhesive polyvinylchloride tapes when applied on steel. The specified technical result is achieved by that adhesive composition for adhesive polyvinylchloride tapes, containing perchorvinyl resin, plasticizing agent that is mixed dioctylphthalate and chlorinated α-olefins, e.g. ethylene oligomerisation residues, pine resin and, probably, bulk additive that is activated mixture of natural zeolite and calcium oxide taken in ratio 9:1, in addition contains brominated 1,2-polybutadiene of average molecular weight within 8000 to 120000. Application of brominated 1,2-polybutadiene in adhesive composition allows for higher adhesion capacity of adhesive polyvinylchloride tapes when applied on steel.

EFFECT: higher adhesion capacity of adhesive polyvinylchloride tapes when applied on steel.
