Tread reclaimed rubber is higher in rubber content and stronger in strength than other parts of tire reclaimed rubber products. It can produce a variety of high-strength, high wear-resistant rubber products; natural rubber is the most widely used general-purpose rubber. The most important feature is good elasticity and high elongation at break. The tread reclaimed rubber and natural rubber can be well compatible. The combination of the two can reduce the raw material cost of rubber products and improve the processing performance, mechanical properties and aging resistance of the rubber materials. Among them, the addition ratio of tread reclaimed rubber and natural rubber directly affects the performance of rubber products.
Data studies have shown that when 20 phr of NR raw rubber is added to the tread reclaimed rubber, the amount of carbon black N220 is 20 phr, the plasticizer 30# oil is 8 to 12 phr, and the anti-aging agent is 1 phr, the blend has good mechanical properties. Performance and aging properties, the tensile strength retention rate and tensile elongation at break retention are more than 90%. Different rubber products can be designed according to the performance of a suitable combination of tread reclaimed rubber and natural rubber.
When rubber products are produced with tread reclaimed rubber as the main raw material, a small amount of natural rubber is used in the formulation of the tread reclaimed rubber products, which can increase the rubber content of the tread reclaimed rubber products, improve the tear strength of the products, and improve the flexibility of the products. Cracking defects, while increasing the elongation of the product elongation, increase the elasticity and elasticity of the tread reclaimed rubber products, greatly improving the physical and mechanical properties of the tread reclaimed rubber products, delaying the aging time, and prolonging the service life.
When natural rubber is used as the main raw material to produce rubber products, the use of tread reclaimed rubber in the formulation of natural rubber products can improve the processing technology of natural rubber (the tread reclaimed rubber itself has good plasticity, good fluidity, and simple processing technology). Improve the anti-aging performance and wear resistance of natural rubber products (Tire recycled rubber itself contains a certain amount of carbon black, antioxidants and other substances); the most important is the natural rubber is expensive, the price of tread reclaimed rubber is very cheap, can reduce the natural The raw material cost of rubber products; no need to plasticize the recycled rubber of the tread, it can be added after the natural rubber plastic refining is finished, and it can also save labor and energy.
The combination of tread reclaimed rubber and natural rubber is of great significance in improving the performance of rubber products and reducing the production cost. Rubber product manufacturers can design a reasonable combination formula according to their own needs, and strive to adjust the performance of rubber products to the best and the price to a minimum. . Hongyun Superfine Tread Reclaimed Rubber is made of 80 to 900-1200 scrap tire rubber powder as raw material. It features high fineness, small specific gravity, high strength, and no taste in the national standard. It is widely used in inner tubes, cables and hoses. The rubber products with smooth surfaces, such as glue, etc., can significantly increase the tear strength and flex resistance of rubber products while reducing the cost of raw materials.
