ADHESIVE COMPOSITION FOR POLYMER COMPOSITE MATERIALS Russian patent published in 2021 - IPC C09J163/10 

FIELD: adhesives.

SUBSTANCE: invention relates to production of adhesive materials for adhering products made of polymer materials and composites based thereon. The adhesive composition for polymer composite materials comprises polyethylene polyamine in an amount of up to 10% wt. and an adhesive mixture including a soluble reactive oligomeric product based on epichlorohydrin and diphenylolpropane, wherein an epoxy diane resin of the brand "ED-20" is used as such product, or a reactive compound, wherein a diglycidyl ether of bisphenol A is used as such compound. The adhesive mixture also includes a high molecular weight thermoplastic polymer - plasticiser, wherein polystyrene PSM 151 is used as such polymer, a solvent, a finely dispersed strengthening inorganic filler, wherein talc and/or aerosil is used as such filler, and a dye.

EFFECT: invention allows for creation of high-strength adhesive seams when adhering products made of heat-resistant polymer materials, ensuring the manufacturability of the adhering process.
