Abstract
The physicochemical, mechanical, and rheological properties of the rubber mixture and vulcanizate obtained based on ethylene and polyethylene copolymers in the presence of a modifier have been studied. Studies have shown that when obtaining,g wear-resistant rubbers based on copolymers of ethylene and propylene, is based on modifying them.
Most importantly, we have selected natural materials and industrial wastes based on local sources of raw materials that can be used as fillers for the preparation of various compositions based on ethylene and propylene copolymers and studied their composition and properties. The ingredients of this composition are: oligomer acrylate modifier (OAM-9), sulfur vulcanizing agent, plasticizer stearic acid, thiuram (TMTD) – tetramethyl thiuram disulfide de and captaxx accelerator, zinc oxide is used as an activator of the vulcanization process in the production of resin. mixtures and carbon blare are used as a filler.
Various rubbertetramethyl thiuramken. For compact tax, a rubber composition without a modifier (OAM-9) was also prepared. A suitable formulation of the rubber mixture was compiled and a homogeneous mixture was prepared according to the recipe in a laboratory roller (temperature 40-60 ° C, time 20-30 minutes). The optimal mode of vulcanization was determined (temperature 150°C, time 20 minutes).
