RUBBER COMPOSITION Russian patent published in 2017 - IPC C08L83/04 C08K3/36 C08K5/14 C09K3/10 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to rubber industry, in particular to development of elastomeric materials for sealing purposes, and can be used for production of rubber components of sealing assemblies of external and internal circuits of machines and mechanisms operating in air medium in all climatic conditions, including Arctic climate conditions. Rubber mixture contains, wt%: silicone rubber – 100, dicumyl peroxide – 1, anti-structuring additive – 8, finely dispersed silicon dioxide – 40, fire-retardants – aluminium hydroxide with particle size not more than 10 mcm – 60–90 or decabromodiphenyl oxide – 15–25, dyes – titanium dioxide pigment – 10, technical carbon – 0.1–2.5 or fine powdered ceramic pigments – 0.1–5.0.

EFFECT: invention reduces flammability of sealing rubber while maintaining acceptable technical level of physical and mechanical properties, heat-and frost resistance.
