Abstract

The effect of hollow polymeric microspheres Expancel 909 DU 80, Expancel 043 DUT 80, Expancel 920 DET 40d25, Expancel 920 DUT 40, Expancel 930 MB 120 and Lega Foam 120 MB on the rheometric parameters of the rubber compound, physical and mechanical and operational properties of oil and petrol resistant rubber was studied. The rubber mixture contained: isoprene SKI‑3 and butadiene- methylstyrene SKMS‑30ARK caoutchoucs, vulcanizing agent – sulfur; vulcanization accelerators – thiuram D and thiazol 2MBS; vulcanization activators – zinc white, stearin; fillers – carbon black N 220, carbon black T 900, natural chalk; softener – rosin; plasticizer – dibutyl phthalate; scorch retarder – N‑nitrosodiphenylamine. The rubber mixture was prepared on laboratory rolls LB 320 160/160 at a roll temperature of 60–70 °C. The vulcanization parameters of the rubber compound were studied on a Mon Tech MDR 3000 Basic rheometer at 150 °C for 30 min in accordance with ASTM D 2084–79. Standard samples for determining physical and mechanical properties were vulcanized at a temperature of 150 °C for 30 min in a P-V‑100–3RT‑2-PCD type vulcanizing press. The main characteristics of the vulcanizates were determined according to the standards in force in the rubber industry. It has been established that rubber containing Expancel 043 DUT 80 microspheres has the best physical and mechanical properties, high wear resistance and resistance to aggressive hydrocarbon media
