Styrene-butadiene ultra-fine recycled rubber is generally made of elastic tape, hose as the main raw material, after crushing, magnetic separation, desulfurization, refining and other processes, with tear resistance, wear resistance and anti-aging, high plasticity, easy mixing, low heat generation, low temperature flexibility, high fineness, no impurities and other characteristics, can be used alone or combined with natural rubber, styrene-butadiene rubber to produce various rubber products, reduce production costs by about 20%. How much styrene-butadiene recycled glue is appropriate? How to design a formulation containing benzene-butadiene ultrafine recycled glue?
1. The dosage method and dosage of styrene-butadiene ultrafine recycled rubber in rubber products
The dosage method and dosage of styrene-butadiene ultrafine recycled rubber in rubber products are determined according to the performance requirements of rubber products. In actual production, styrene-butadiene recycled rubber can be used alone, or in combination with styrene-butadiene rubber and natural rubber in appropriate proportions; For example, 10-20 parts of styrene-butadiene recycled rubber can be mixed in anti-skid tires, and 50 parts can be increased to 50 parts in seals. When using styrene-butadiene ultra-fine recycled rubber for rubber products, it is recommended to conduct a small test first to observe the fluidity, vulcanization speed and changes in finished product performance.
2. The main application areas of styrene-butadiene ultrafine recycled rubber
Styrene-butadiene ultrafine recycled rubber has a wide range of applications in rubber products, including anti-skid tires, sole sponges, foam rubber tubes, rubber plates, rubber strips, conveyor belts, V-belts, inflatable core films and other products. For E5LYY722 example, the use of an appropriate amount of ultra-fine styrene-butadiene recycled rubber in tire tread adhesive can ensure the wear resistance of the finished product while reducing the cost of raw materials; The mixing of styrene-butadiene recycled rubber in sidewall glue can improve the aging resistance of vulcanized rubber.
3. Key points of formula design of styrene-butadiene ultrafine recycled rubber production rubber products
When producing rubber products from styrene-butadiene ultrafine recycled rubber, sulfur, sulfur donor, and organic peroxide vulcanization can be used. The sulfur content in styrene-butadiene rubber and styrene-butadiene recycled rubber is lower than that in natural rubber, and the vulcanization speed can be accelerated by increasing the amount of accelerators (such as CZ and DM). Carbon black is the most commonly used reinforcing agent, such as carbon black N330, combined with calcium carbonate to reduce costs; Commonly used softeners include coumallon resin, pine tar, petroleum-based operating oil, etc.
When using styrene-butadiene ultra-fine recycled rubber to produce rubber products, rubber product manufacturers not only need to choose the appropriate styrene-butadiene recycled rubber and reasonably design the rubber formula, but also need to appropriately adjust the production process parameters, especially the compounding and vulcanization processes, and then share with you the key points of the production process of styrene-butadiene ultrafine recycled rubber.
