Problems solved by technology
[0002] Farm vehicle tires are often used in farmland, ditches and other places that are more harmful to tires. There are many crop stubbles in farmland, and there are many sharp gravels in ditches, which are very harmful to tires. Now we have to solve this problem Most of the solutions are to replace tires, but seldom improve the puncture resistance of agricultural vehicle tires, resulting in frequent tire replacement and heavy burden on users, and the price of puncture-resistant rubber suitable for high-end tires is high. Difficult to apply to the field of agricultural vehicle tires

Embodiment 1
[0026]
[0027]
[0028] After using the above combined formula, the measured performance is as follows: Shore A hardness 62, tensile strength 21MPa, elongation 538%, abrasion performance far exceeds the benchmark requirement, reaching 101ml, far lower than the benchmark requirement of 150ml. The cost of rubber pure natural rubber formulations has dropped a lot, but the physical properties are basically the same or even better than pure natural rubber formulations.
Embodiment 2
[0030]
[0031] After using the above combined formula, the measured properties are as follows: Shore A hardness 60, tensile strength 20MPa, elongation 524%, abrasion resistance 106ml, rubber pure natural rubber formula cost much lower, but physical properties are basically the same or even better than pure natural rubber Natural gum formula.

Abstract
The invention discloses a tyre sizing material of an agricultural vehicle. The tyre sizing material is prepared from the following components in percentage by weight: 15-20% of natural rubber, 28-35% of butadiene-styrene rubber (SBR), 6-9% of a softener, 6-8% of natural reclaimed rubber, 25-30% of carbon black N339, 0.4-0.6% of resin, 2-3% of a protective system, 1-2% of a vulcanization system and 2.5-3.5% of other assistants. The tyre sizing material disclosed by the invention is low in cost and excellent in physical property, the excellent physical and mechanical property is maintained under the condition of greatly lowering the cost, and the abrasion performance is far beyond the benchmark. The tyre sizing material has good heat resistance and resistance to ozone aging, and the aging characteristic change rate is lower than that of similar products under same aging conditions.
Description
technical field [0001] The invention relates to a rubber, in particular to an agricultural vehicle tire rubber compound and a preparation method thereof. Background technique [0002] Agricultural vehicle tires are often used in farmland, ditches and other places that are more harmful to tires. There are many crop stubbles in farmland, and there are many sharp gravels in ditches, which are very harmful to tires. Now we have to solve this problem Most of the solutions are to replace tires, but seldom improve the puncture resistance of agricultural vehicle tires, resulting in frequent tire replacement and heavy burden on users. The puncture-resistant rubber suitable for high-end tires is expensive and very expensive. It is difficult to really apply to the field of agricultural vehicle tires. Contents of the invention [0003] The object of the present invention is to solve the above problems and provide a low-cost tire compound that can improve the puncture resistance of ag...
