EPOXY BINDER FOR POLYMER COMPOSITE MATERIALS Russian patent published in 2014 - IPC C08L63/00 

FIELD: chemistry.

SUBSTANCE: invention relates to epoxy composite binders, used for production of composite materials, for instance fibreglass plastics and carbon-fibre-reinforced plastics, manufactured by methods of vacuum infusion and RTM, of wide spectrum of application, for instance in aviation, aerospace, ship-building, automobile and other branches of industry. Epoxy binder for polymer composite materials includes epoxy diane resin, diluents and hardener. As diluents used is furfural acetone resin, as hardener used is triethanolamine titanate, with the following ratio of binder components, wt.p.: epoxy diane resin - 100; furfural acetone resin- 5…50; triethanolamine titanate- 5…15.

EFFECT: creation of binder based on epoxy composition, which possesses increased exploitation characteristics, in particular lower viscosity and high heat resistance, which can be efficiently used in production of composite materials, produced by methods of vacuum infusion and RTM.
