Problems solved by technology

However, an important problem brought about by the fast driving speed is that the rubber track is seriously heated, and the thermal conductivity of rubber is poor, so the heat cannot be removed in time, and a large amount of heat will be accumulated on the rubber track, which will cause the temperature to rise. Cause thermal damage, accelerate its aging speed, and reduce its mechanical properties. If the temperature is too high, it will degrade the rubber molecular chain and cause early damage.
Generally, during use, the method of stopping construction will be used to reduce the temperature of the track, but this will greatly affect the efficiency of the rubber track

Embodiment 1

[0100] Each of embodiment 1 and comparative example 1 provides a kind of rubber material, and the ratio of raw materials is as shown in table 2 below:

[0101] Table 2

[0102]

[0103]

[0104] Example 1

[0105] According to the ratio of raw materials shown in Table 2, the rubber was prepared according to the following steps.

[0106] step one:

[0107] Prepare magnesium oxide, zinc oxide, stearic acid, anti-scorch agent PVI, pulverize and dry, sieve, weigh in proportion and put into a container and stir evenly.

[0108] Step two:

[0109] Add natural rubber, styrene-butadiene rubber, rare earth butadiene rubber, and white carbon black 1115MP into the open mill for mastication. The speed ratio of the front and rear rollers of the open mill is 1:1.2, and the roll distance is adjusted to 0.9mm, and the plasticization is completed. Finally, add the ingredients in step 1 to continue masticating, and after the masticating is completed, cool and park for 15 hours.

Abstract

The invention relates to a low-heat-generation rubber material. The material is obtained by refining a raw material composition containing the following components: natural rubber, butadiene styrene rubber, rare earth butadiene rubber, a vulcanization accelerator, insoluble sulfur, magnesium oxide, zinc oxide, stearic acid, an anti-aging agent, carbon black, white carbon black, carbon nanotubes, asilane coupling agent, an anti-scorching agent, a plasticizer, a flame retardant and a light stabilizer.

Description

technical field [0001] The invention relates to the field of materials, in particular to a low heat generation rubber material and a rubber track. Background technique [0002] Rubber tracks are widely used in tracked vehicles, especially in construction machinery, agricultural machinery, military machinery and equipment. With the development of industrialization, people have higher and higher requirements for rubber crawlers, and rubber crawlers are developing in the direction of diversification and complete specifications. [0003] Compared with metal track, the main advantage of rubber track is fast driving speed. However, an important problem brought about by the fast driving speed is that the rubber track is seriously heated, and the thermal conductivity of rubber is poor, so the heat cannot be removed in time, and a large amount of heat will be accumulated on the rubber track, which will cause the temperature to rise. Cause thermal damage, accelerate its aging speed,...
