ADHESIVE COMPOSITIONS CONTAINING GRAPHENE CARBON PARTICLES Russian patent published in 2017 - IPC C09J11/04 

FIELD: chemistry.

SUBSTANCE: invention relates to adhesive compositions used, for example, for gluing blades of wind plants, gluing automotive structural components, for coating, as well as to methods of forming a laminated substrate. Adhesive compositions include (a) a first component containing one or more epoxy compounds, (b) a second component containing a curing component which enters into chemical reaction with first component, and (c) particles of graphene carbon, having density in pressed state 0.9 g/cm³ or less, or 0.5 wt% of a solution of said particles of graphene carbon in butyl cellosolve has bulk liquid conductivity of at least 100 mcS, determined using a conductivity meter.

EFFECT: compositions have improved rheological properties (higher shear thinning and higher thixotropy index), improved mechanical properties, such as high modulus of elasticity in tension.
