RUBBER MIXTURE Russian patent published in 2005 - IPC

FIELD: rubber and tire industry.

SUBSTANCE: invention relates to rubber mixtures based on unsaturated rubbers and can be used in manufacturing protective rubbers. The rubber mixtures comprises oleic acid additionally in the mass ratio of stearic and oleic acids = 1:1.5, respectively, in the following ratio of components, mass. p. p.: unsaturated rubber, 100; sulfur, 1.7-2.2; rubber accelerator, 1.4-1.8; softening agent, 8.0-15.0; protective wax, 1.0-2.0; N-isopropyl-N'-phenyl-n-phenylenediamine, 1.0; polymerized 2,2,4-trimethyl-1,2-dihydroquinoline, 2.0; N-cyclohexylphthalimide, 0.2-0.3; technical carbon, 55.0-60.0; zinc oxide, 3.0-5.0; stearic acid, 0.8; oleic acid, 1.2. Invention provides expansion assortment of rubber mixtures eliciting the improved complex of technological and physical-mechanical properties: improved technological and some physical-mechanical properties of rubbers - increased wear resistance of rubbers, fatigue endurance and reduced cost of articles due to change of 60% of stearic acid for more cheap oleic acid.

EFFECT: improved properties of rubber mixtures and rubbers.
