Abstract

The invention discloses super wear-resistant rubber, a preparation method and a crawler belt. The super wear-resistant rubber is prepared from the following basic materials in parts by weight: 100 parts of raw rubber, 2-5 parts of a vulcanization accelerator, 2-4 parts of magnesium oxide, 2-4 parts of zinc oxide, 1-2 parts of stearic acid, 3-6 parts of an anti-aging agent, 30-60 parts of carbon black, 10-30 parts of surface modified nano-diamond, 0.5-4 parts of graphene, 0.5-2 parts of a scorch retarder CTP, 0.5-2 parts of a light stabilizer, and 1-3 parts of a flame retardant. Through different raw rubber components and addition of the anti-aging agent, the scorch retarder, the flame retardant, the carbon black, the surface modified diamond, the graphene, the light stabilizer and the like, the wear resistance of the rubber is improved, and the service life of the rubber is prolonged; during actual use, the components and the proportion of the raw rubber and the proportion of the compounding agent can be adjusted according to actual requirements, so that the use requirements of different public products are met; the vulcanization accelerator, the magnesium oxide, the zinc oxide, the stearic acid and the like promote the vulcanization process of the rubber, so that the vulcanization of the rubber is more sufficient, different production methods are adopted for raw rubber with different components, and the requirement for wear resistance of the rubber is met.

Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to a super wear-resistant rubber, a preparation method and a track. Background technique [0002] Rubber track is a composite product made of rubber and metal or fiber materials. It is a new type of walking part that spans machinery and rubber and is developed to simulate metal tracks. It has the advantages of no damage to the road surface, small grounding specific pressure, good wetland passability, small vibration, low noise, fast speed, reduced overall weight, and good corrosion resistance. It is used in construction machinery, construction machinery, agricultural machinery, and garden machinery. The proportion of applications continues to increase. However, the rubber track is still a vulnerable part at present. The service life of the most advanced products at home and abroad is only 10,000km. For the rubber track with a load capacity of more than 15 tons, early wear i...
