Abstract

The invention discloses a rubber material for wear-resistant and antistatic rubber rollers. The raw materials include, by weight, 50-70 parts of carboxylated nitrile rubber, 30-50 parts of EPDM rubber, and 5-25 parts of naphthenic oil , 15-30 parts of reinforcing agent, 3-6 parts of modified nano-zinc oxide, 6-10 parts of plasticizer, 2-3 parts of vulcanizing agent, 1-3 parts of accelerator, 1-5 parts of auxiliary agent; wherein, The weight percent content of propylene units in the EPDM rubber is 40-50%, the weight percentage content of ethylene units is 45-55%, and the weight percentage content of ethylidene norbornene units is 4-6%. The invention adopts the blending of EPDM rubber obtained by polymerization of ethylene, propylene and ethylidene norbornene with a specific ratio and carboxylated nitrile rubber, which reduces the hardness of EPDM rubber and improves the tensile strength and wear resistance Performance, adding modified nano zinc oxide, improves the wear resistance and antistatic performance of the rubber roller, and at the same time improves the rubber vulcanization activity, shortens the vulcanization time and reduces the production cost.

Description

technical field [0001] The invention relates to the technical field of twist stick rubber materials, in particular to a rubber material for antistatic and wear-resistant rubber rollers. Background technique [0002] Rubber rollers are a main variety of rubber products, widely used in metallurgy, papermaking, fiber textiles, printing and dyeing, wood processing, plastic film processing, office equipment manufacturing and other industries, and are important industrial accessories.
