Waste tires can be processed in tire reclaimed rubber after a series of process operations, and tire reclaimed rubber can be reused in the production of tires through a rational formula design. The use of tire reclaimed rubber to produce tires, different types of rubber tires in the reclaimed rubber performance requirements and the amount of mixed different, the performance is more obvious is the agricultural vehicle tires and truck tires.
Compared with agricultural vehicle tires, the weight of heavy-duty tires is much greater than that of agricultural vehicles. Generally, the heavy-duty tires travel fast on smooth high-speed roads. They require high wear resistance performance and physical comprehensive performance, and have low friction and heat generation. Heavy-duty tires do not puncture tires at high speeds due to excessive heat generated by friction; agricultural vehicle tires are usually driven in the field and are used for crop planting and harvesting. They have low bearing weight and low speed, but the road conditions are complex and may very well In response to slopes, paddy fields, stones, etc., compared with truck tires, the tear resistance and puncture resistance of agricultural vehicle tires are even higher than their wear resistance requirements. As for comprehensive performance, the requirements for rubber raw materials for truck tires are higher than those for agricultural vehicles. Therefore, the amount of tire reclaimed rubber used in truck tires is not too much, and the amount of tire reclaimed rubber used in agricultural vehicle tires can be appropriately increased.
In many tire reclaimed rubber products, the tread reclaimed rubber has the highest gel content, the best elasticity, high strength, and excellent wear resistance, and therefore can be used in the production of various rubber tires. For lightweight heavy duty tires in heavy-duty tires, the blending amount of tire reclaimed rubber with a tensile strength above 16 Mpa can be around 30%. The adjustment of tire weight can be achieved by adjusting the proportion of rubber raw materials for load-bearing tires and increasing the amount of anti-aging agents. The performance of rubber-loaded tires; agricultural vehicle tires are usually produced by using styrene-butadiene rubber and tire reclaimed rubber in combination, and the proportion of tire reclaimed rubber blended can be over 80%. At the same time, the vulcanization efficiency of agricultural vehicle tires with tire reclaimed rubber is higher. The tear strength and tensile strength of automobile tires have also been improved, and ozone resistance and aging resistance are better than those of agricultural vehicle tires produced from pure styrene-butadiene rubber.
Whether it is the production of agricultural vehicle tires or heavy-duty tires, when selecting the tire reclaimed rubber, we must select the right tire reclaimed rubber product according to the needs of its own products. Based on the rubber tire index requirements, choose the tire reclaimed rubber product that is closest to its index. Therefore, in order to ensure the quality of rubber tires, we can minimize the raw material cost of rubber tires.
