THERMALLY CONDUCTIVE SILICONE COMPOSITION AND CURED PRODUCT OF SAME Russian patent published in 2017 - IPC C08L83/07 C08K3/36 C08K9/06 C08L83/05 C08L83/06 

FIELD: chemistry.

SUBSTANCE: invention relates to a thermally curable, thermally conductive silicone lubricant composition comprising the following main components: (A) 100 wt. parts of organopolysiloxane having a viscosity of 100 to 100,000 mPa⋅S at 25°C and containing at least one alkenyl group per molecule, (B) from 10 to 900 wt. parts of organopolysiloxane with the general formula

,

where R¹ Is an independently unbranched alkyl group having from 1 to 10 carbon atoms, R² Is an independently unbranched alkyl group having 1 to 10 carbon atoms, n is an integer from 2 to 100, and is an integer of 1 to 3, (C) an organohydride polysiloxane containing at least two hydrogen atoms bonded to silicon, Per molecule in such an amount that the number of Si-H groups divided by the number of alkenyl groups in components (A) and (B) can be in the range of 0.1 to 10.0, (D) a catalyst selected from the group, consisting of platinum and platinum compounds in an amount such that 0.1 to 500 m of the platinum atom, based on the weight of the component (A), (F) from 100 to 20,000 wt. parts of heat conductive filler with a thermal conductivity of at least 10 W/m °C and (G) from 0.1 to 100 wt. parts of highly dispersed silicon dioxide, which is particles of colloidal silicon dioxide with a treated surface.

EFFECT: lubricant has a good form stability, such that the shape can remain unchanged immediately after it is imparted and remains elastic after curing.
