Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the examples, and the parts involved in the examples are all calculated by weight.

[0013] Weigh 65 parts of No. 1 smoked sheet and put it in the second section of mastication for 24 hours, mix the smoked sheet after mastication with 35 parts of butadiene rubber and 10 parts of polyurethane in a banbury mixer for 1 minute, then drop into 50 parts of carbon black, promote 1.2 parts of anti-aging agent, 2 parts of stearic acid, 5 parts of zinc oxide, 3 parts of anti-aging agent, 2 parts of dispersant, 2 parts of paraffin, 0.2 parts of molybdenum disulfide, 5 parts of white carbon black, 8 parts of third line oil, 1.8 parts of sulfur, Knead for 4~5 minutes, control the temperature of banburying below 110 degrees, then lower the sheet of the mill to cool down, stop for 24 hours to add vulcanization, produce semi-finished products, mold and vulcanize at 160°C x 12 minutes.

Abstract

The invention discloses a rubber composition for a double spiral rubber reversing wheel. The rubber composition consists of the following components in part by weight: 65 parts of tobacco flake No.1 section 2, 35 parts of butadiene rubber, 10 parts of blending-type polyurethane, 1.2 parts of accelerator, 2 parts of stearic acid, 5 parts of zinc oxide, 3 parts of age resister, 2 parts of dispersing agent, 2 parts of paraffin, 0.2 part of molybdenum disulfide, 50 parts of carbon black, 5 parts of white carbon black, 8 parts of third line oil, and 1.8 parts of sulfur. The rubber composition for the double spiral rubber reversing wheel has high elasticity, intensity, abrasive resistance, tearing strength and ageing resistance; and through detection, the service life of the double spiral rubber reversing wheel which is prepared from the rubber composition for the double spiral rubber reversing wheel reaches more than six months when the double spiral rubber reversing wheel works.

Description

technical field [0001] The invention relates to a rubber composition, in particular to a rubber composition for a double-helix rubber reverse wheel. The invention also relates to a preparation method of the rubber composition. Background technique [0002] The rubber reversing wheel is the core component of an environmentally friendly road sweeper. The rubber reversing wheel includes a polyurethane soft foam shaft sleeve and a rubber outer sleeve set outside the polyurethane soft foam sleeve. The outer surface of the rubber outer sleeve There are burrs, and the burrs are spirally distributed on the outer surface of the rubber outer sleeve. When the road sweeper cleans up the garbage on the ground, it uses the burrs on the outer surface of the rubber sleeve of the rubber reversing wheel to rub against the ground to pick up foreign objects on the ground, and then sends the garbage to the garbage storage box in the car through the conveyor belt. At present, the rubber counter...
