METHOD OF IMPROVING ADHESION OF SILICON COMPOSITE MATERIALS OBTAINED FROM POLYADDITION REACTION Russian patent published in 2010 - IPC C08L83/04 C08L83/07

Abstract RU 2401850 C1

FIELD: chemistry.

SUBSTANCE: invention relates to silicon composite materials obtained from a polyaddition reaction. The silicon composite material, which has high adhesion and is obtained from polydimethylsiloxane with terminal vinyl groups of general formula (CH₂=CH)(CH₃)₂Si-[O-Si(CH₃)₂-]_nO-Si(CH₃)₂(CH=CH₂)_, (n=1280-1300, weight ratio of vinyl groups equals 0.08 wt %, dynamic viscosity equals 92822-93000 cP), contains at least 40 pts. wt organosilicon resin of general formula {[(CH₃)₃ SiO_1/2]_x[SiO₂]₁[(CH₃)₂SiO]_y[CH₃VinSiO]_z} (x=0.9-1.2; y=0-0.4; z=0.1-0.4), and an adhesion-enhancing additive in form of 5-25 pts. wt halloysite per 100 pts. wt polymer. The method is relevant for filling compounds, sealing and damping coatings and other possible applications.

EFFECT: higher adhesion power of silicon composite materials obtained from a polyaddition reaction.
