POWDER FILLER FOR ELASTOMER MATERIALS ON BASE OF RUBBER Russian patent published in 2011 - IPC C08L21/00 C08L11/00 C08L23/34 C08K9/04 

FIELD: machine building.

SUBSTANCE: invention refers to rubber industry, particularly to development of powder fillers for thermo-plastic elastomer materials on base of rubber and can be implemented at fabrication of various extrusive profiles and moulded flexible parts made of rubber mixtures for automobile, cable, light and building industries. For elastomer materials on base of rubber, particularly, poly-chloroprene, sulpho-chlorinated polyethylene powder filler contains natural mineral schungite and as modifier - methane-amine and/or teotropine. Also, size of powder particles of filler with modifier is chosen from 100 nm to 20 mcm, and external specific surface of filler with modifier is from 20 to 40 m²/g. Methane-amine and/or teotropine are introduced by dissolution or after their intermixing with schungite, for example, in a ball mill or in impact mill.

EFFECT: increased strength of elastomer materials on base of rubber at stretching, maintaining percent elongation of elastomer materials on base of rubber and maintaining process characteristics during treatment of materials.
