Problems solved by technology

For example, sulfur is used as a rubber vulcanizing agent, but there are many problems in the traditional vulcanization method, such as high content of free sulfur, poor solubility, uneven cross-linking structure, etc.; the surface properties of fillers are very different from those of rubber, resulting in poor compatibility , although the silane coupling agent can improve the compatibility, the interaction between the silane coupling agent and the rubber is weak, which is not conducive to the dispersion of silica in the rubber, and the price is relatively expensive, which is not conducive to cost control

Abstract

The invention belongs to the field of rubber, and relates to low-rolling-resistance rubber and a track; the rubber raw material comprises raw rubber, an accelerant, a vulcanizing agent, an activatingagent, an anti-aging agent, carbon black, a flame retardant and a light stabilizer, and the low-rolling-resistance rubber is prepared by mixing through an open type rubber mixing mill. The track comprises tooth rubber arranged on the annular inner side of the caterpillar band and pattern side rubber arranged on the annular outer side of the caterpillar band. When the rubber disclosed by the invention is prepared, the self-made vulcanizing agent which is good in dispersity, high in vulcanizing speed and good in vulcanizing performance is added into the rubber, so that the hysteresis characteristic of the rubber is reduced, and the rolling resistance of the rubber is effectively reduced while the comprehensive performance of the rubber is maintained.

Description

technical field [0001] The invention belongs to the field of rubber, and in particular relates to a low-rolling-resistance rubber, a track and a preparation method thereof. Background technique [0002] Rubber track is a tracked vehicle running part made of rubber and skeleton, which has the advantages of small ground pressure, fast speed, low noise, small vibration, and road friendly. Therefore, in the fields of construction machinery, special equipment, agricultural and forestry machinery, etc., the application rate of rubber tracks is constantly increasing. But due to the long-chain structure of rubber macromolecules and the stepwise nature of macromolecular motion, the strain of rubber cannot respond instantaneously to stress. When the drive wheel applies power to the rubber track, the rubber track not only has to overcome the friction with the rollers, guide wheels, ground, etc., but also overcomes the internal resistance of the rubber molecules. The specific energy lo...
