POLYMER COMPOSITION FOR ACCELERATED COLD CURING Russian patent published in 2016 - IPC C08L63/02 C08G59/56 C08K3/36 C08K9/00

Abstract RU 2595651 C2

FIELD: chemistry.

SUBSTANCE: invention relates to cold curing polymer compositions based on epoxy diane resin and can be used in composite-coupling repair of oil and oil product pipelines in various climatic conditions. Composition includes epoxy diane resin, curing agent and filler. Curing agent used is a mixture an amine curing agent with toluene sulphonic acid. Filler is 90% made up of VS quartz sand treated with aminoethylaminopropyltrimethoxy silane in amount of 1 % to 3 % of weight of curing agent.

EFFECT: invention improves quality and speed characteristics of process of adhesion of resin and filler and reduces pipeline down time by 4-6 hours after composite-coupling repair of strength of polymer composition for compression 70 kg/cm² during 18-20 hours.
