Problems solved by technology

However, the commonly used rubber track has a low load-bearing capacity and is prone to early aging, which cannot meet the requirements for load-bearing capacity and service life of construction machinery.
[0003] At present, domestic research on the anti-aging performance of rubber tracks has improved the aging properties of rubber tracks by adding accelerators, anti-aging agents, plasticizers, diatomaceous earth powder, etc., but this also leads to a decrease in the strength of rubber tracks, to a certain extent The use level of the crawler is reduced; the domestic research on the bearing capacity of the rubber crawler mainly improves the strength of the crawler by adding carbon black, white carbon black, homogenized anti-tearing agent, etc. This method improves the strength of the crawler, but There is no improvement in the anti-aging performance of the track, and even the early aging phenomenon of the track

preparation example Construction

[0036] The preparation method of described high-strength rubber track is as follows:

[0037] step one:

[0038] Raw material preparation: prepare raw rubber, cut it into wedge-shaped pieces of 8kg, and then dry; crush and dry the compounding agent, sieve it, and weigh it according to the proportion.

[0039] Step two:

[0040] Mastication: Set the speed ratio of the front and rear rollers of the mill to 1:1.2, adjust the roller distance of the mill to 0.8mm, add raw rubber for plastication, and make triangular bags, 5 times.

[0041] Step three:

[0042] Mixing: Adjust the roller distance of the open mill to 0.8mm, and add raw rubber into the mixing.

[0043] Step four:

[0044] Final refining: Add mixed rubber into the open mill, and then add various compounding agents for final refining. After the powder is finished, pack it several times to evenly disperse the raw rubber and compounding agents. Then the rubber material was unloaded and parked for 4 hours.

Abstract

The invention discloses a rubber track. The rubber track is prepared from raw materials including raw rubber, sulfur, an accelerant, magnesia, zinc oxide, an anti-aging agent, a titanate coupling agent, an anti-coking agent, carbon black, a flame retardant, micro-crystal wax and a light stabilizer through plastication, mixing and final refining. The strength and wear resistance of rubber are enhanced by adding different raw rubber components, carbon black, the titanate coupling agent and the like. The aging resistance of rubber is improved and the service life of rubber is prolonged by addingthe anti-aging agent, the anti-coking agent and the light stabilizer. Thus, the rubber track has the characteristics of high strength and high reliability.

Description

technical field [0001] The invention relates to a rubber material and a preparation method thereof, in particular to a high-strength rubber track and a preparation method thereof. Background technique [0002] The rubber track is a new type of walking part developed to simulate the metal track. It has good longitudinal flexibility and lateral rigidity. The advantages of road surface, fast speed, and light weight have been widely used in agricultural machinery, and the proportion of application in construction machinery has continued to increase. However, the currently widely used rubber crawlers have low load-bearing capacity and are prone to early aging phenomena, which cannot meet the requirements of load-bearing capacity and service life on construction machinery. [0003] At present, domestic research on the anti-aging performance of rubber tracks has improved the aging properties of rubber tracks by adding accelerators, anti-aging agents, plasticizers, diatomaceous ear...
