Embodiment 1

[0033] Embodiment 1: butadiene rubber: 73 parts; Natural rubber: 27 parts; Reinforcing agent: 51 parts; Vulcanizing agent: 2.1 parts; Anti-aging agent: 6.7 parts; Agent: 4.6 parts; Accelerator: 2.6 parts.

[0034] For rubber materials, natural rubber has good elasticity, strength and adhesion, but poor wear resistance; butadiene rubber has good wear resistance, but its elasticity, adhesion and strength are poor. Therefore, a combination of natural rubber and butadiene rubber is used.

[0035] Selection of reinforcing agent: Due to the high wear resistance and strength requirements of the super wear-resistant conveyor belt, the reinforcing agent is selected through experiments. Through our many tests, we finally selected super wear-resistant carbon black N375 and high wear-resistant carbon black N234 provided by Qingdao Evonik Chemical Co., Ltd. Through test comparison, according to parts by weight, when the ratio of N375 and N234 is 55:45 , the abrasion resistance reaches ≤3...

Embodiment 2

[0047] Embodiment 2: The composition of the cover rubber material is in the following parts by weight: butadiene rubber: 71 parts, natural rubber: 29 parts, reinforcing agent: 48 parts, vulcanizing agent: 2.5 parts, anti-aging agent: 7.2 parts; dispersant: 1.8 parts parts; coupling agent: 2.0 parts; active agent: 3.9 parts; accelerator: 2.2 parts.

[0048] Selection of reinforcing agent: Due to the high wear resistance and strength requirements of the super wear-resistant conveyor belt, the reinforcing agent is selected through experiments. Through our many tests, we finally selected super wear-resistant carbon black N375 and high wear-resistant carbon black N234 provided by Qingdao Evonik Chemical Co., Ltd. Through test comparison, according to parts by weight, when the ratio of N375 and N234 is 55:45 , the abrasion resistance reaches ≤35mm 3 .

[0049] RD, 4020 and 4010NA and microcrystalline wax were selected as the anti-aging agent, and the ratio of the four components w...

Embodiment 3

[0054] Embodiment 3: The composition of the cover rubber material is in the following parts by weight: butadiene rubber: 67 parts, natural rubber: 33 parts, reinforcing agent: 45 parts, vulcanizing agent: 2.4 parts, anti-aging agent: 6.5 parts; dispersant: 1.5 parts parts; coupling agent: 1.9 parts; active agent: 3.7 parts; accelerator: 1.8 parts.

[0055] Selection of reinforcing agent: Due to the high wear resistance and strength requirements of the super wear-resistant conveyor belt, the reinforcing agent is selected through experiments. Through our many tests, we finally selected super wear-resistant carbon black N375 and high wear-resistant carbon black N234 provided by Qingdao Evonik Chemical Co., Ltd. Through test comparison, according to parts by weight, when the ratio of N375 and N234 is 55:45 , the abrasion resistance reaches ≤35mm 3 .

Abstract

The invention relates to ultrawear-resistant rubber conveyer belt cover rubber which is prepared from the following materials in parts by weight: 65-75 parts of butadiene rubber, 25-35 parts of nature rubber, 42-52 parts of reinforcing agent, 0.8-2.5 parts of vulcanizer, 5-8 parts of antiager, 1-2.5 parts of dispersing agent, 1.5-3.0 parts of coupling agent, 3-5 parts of active agent and 1-3 parts of accelerator. The invention also discloses a preparation method of the ultrawear-resistant rubber conveyer belt cover rubber. A conveyer belt prepared by adopting the technical scheme can improve the wear resistance, lower the wear resistance, and achieve better cover rubber strength and elongation at break.

Description

technical field [0001] The invention relates to a rubber product technology, in particular to a super wear-resistant rubber conveyor belt cover rubber and a preparation method thereof. Background technique [0002] Conveying is an indispensable tool in the material conveying industries such as mines, power plants, coal, and docks, and its continuity and efficiency of conveying play a huge role. At the same time, due to the increase in the current conveying volume, the large transport capacity and long transport distance of the steel wire rope conveyor belt are also gradually significant. But at the same time, the conveyor belt is affected by the material during operation, and the long-term contact and friction with the conveyor roller and the material will cause the conveyor belt cover rubber to be non-wearable and easy to fall off, resulting in frequent maintenance and short life. Therefore, the operating cost is higher, and the scrapped conveyor belt cannot be reused. Pr...
