Abstract

The invention discloses an elevator roller rubber compound for a vertical elevator. The rubber compound comprises, by weight, 70-100 parts of natural rubber, 0-30 parts of butadiene rubber, 60-100 parts of N-550 carbon black, 0-15 parts of high aromatic oil, 1-3 parts of an anti-aging agent RD, 1-3 parts of an anti-aging 4010 NA, 4-6 parts of indirect method zinc oxide, 0.5-1.5 parts of stearic acid, 1-3 parts of microcrystalline wax ZF-10, 1-3 parts of a dispersing agent AT-A, 3-7 parts of coumarone, 0.1-0.6 part of a scorch retarder, 2-5 parts of resorcinol, 1.0-2.0 parts of insoluble sulfurIS-60, 0.5-2 parts of an accelerant NS, 0.5-1.5 parts of a vulcanizing agent DTDM and 1.5-4 parts of an accelerant HEXA-80. The rubber compound is small in compression permanent deformation and longin fatigue life, and therefore the use requirements under long-time harsh conditions are met.

Description

technical field [0001] The invention relates to an elevator roller, an important component used in a vertical elevator, in particular to a formula and a manufacturing process of a rubber component contained in the elevator roller used in a vertical elevator. Background technique [0002] my country has become the world's largest elevator production and consumption market. The world's major elevator brand companies have established wholly-owned or joint ventures in my country, which is the world's factory and manufacturing center in the elevator field. Elevator rollers are used in vertical elevators, which play a vital role in the stability and comfort of the elevator. At present, the structure of the existing elevator rollers generally includes standard bearings, roller bearing seats and rubber / plastic outer rings. The overall exposed structure of the ring, then put the standard bearing into the roller bearing seat, and finally rivet the standard bearing and the roller bear...
