FIELD: rubber-technical production.
SUBSTANCE: invention relates to rubber mixtures for making frost-resistant and oil-and-gasoline-resistent rubber articles with high physical and mechanical properties and resistance to thermal aging, used in automotive, oil and oil refining industries. Rubber mixture contains, pts. wt.: BNKS-18AMN rubber – 100.0, UHMWPE – 5.0–15.0, technical carbon of N550 grade – 80.0, dibutyl sebacetate – 20.0, zinc oxide – 5.0, 6PPD – 1.0, 4010 – 1.0, antioxidant D – 4.0, stearic acid – 1.75, altax – 1.5, CZ – 1.5, dicumyl peroxide – 2.0 and sulfur 1.0.
EFFECT: invention increases resistance to thermal aging in hydrocarbon medium and air, improves physical and mechanical properties, frost resistance and wear resistance.
