RUBBER MIXTURE MODIFIED WITH COMPOSITION OF ULTRA-HIGH MOLECULAR WEIGHT POLYETHYLENE AND MAGNESIUM NANO-SPINEL Russian patent published in 2011 - IPC C08L9/02 C08L23/06 C08K3/04 C08K3/06 C08K3/22 C08K5/09 C08K5/10 C08K5/18 C08K5/31 C08K5/375 

FIELD: chemistry.

SUBSTANCE: rubber mixture based on butadiene-nitrile rubber BNKS-18 is prepared. 2-5 pts.wt synthetic magnesium nano-spinel with particle size less than 100 nm is added to 10 pts.wt powdered ultra-high molecular weight polyethylene per 100 pts.wt rubber and then mixed for 2-3 minutes in a blade mixer. The obtained composition is added to the rubber mixture on rollers or rubber mixer. The rubber mixture also contains natural rubber, sulphur, N,N-diphenylguanidine, di-(2-benzothiazolyl)-disulphide, zinc oxide, aldol-α-naphthylamine, N-(4-hydroxyphenyl)-naphthylamine-2, N-(1,3-dimethylbutyl)-N-phenylenediamine-1,4, technical carbon P803, stearic acid, dibutyl phthalate.

EFFECT: invention enables to obtain rubber with given level of operational properties with high and stable complex of operational characteristics.
