All the use of tire reclaimed rubber can produce ordinary rubber products, significantly reducing the cost of raw materials, but also a lot of rubber products such as miscellaneous pieces of rubber, rubber plates and other manufacturers commonly used methods of production. However, in order to improve the service performance and service life of reclaimed rubber products and make up for the defects of reclaimed rubber tires, there are many places to pay attention when designing rubber product formulations, including the choice of vulcanization accelerator, the amount of various fillers, With the accelerator and other cooperation. Xiaobian posted on the platform today using a tire reclaimed rubber production of ordinary rubber formulations, and we share the exchange:
Reclaimed rubber, 300 parts; Baiyin plastic, 20 parts; naphthenic oil / engine oil / pine tar, according to the appropriate amount of hardness of the product; sulfur, 8-10 g / kg; polyethylene glycol, ; 1 part of polysulfide rubber; 1 part of wax; 1 part of accelerator; 0.5 part of accelerator M; 0.5 part of accelerator D; 1 part of accelerator RD; 1 part of accelerator DM; 1 part of accelerator CS / NS; Thiuram, 1-1.2 g / kg; carbon black, qs; light calcium carbonate, qs.
The use of tire reclaimed rubber production of ordinary rubber products, in order to improve the flex cracking of rubber products, reclaimed rubber products recipes can be added to a certain amount of natural rubber, such as the above formula of tobacco smoke, neither will The cost of rubber products to bring the burden, but also can improve the plastic content of recycled rubber products, rubber tires to extend the life of renewable products.
In tire reclaimed rubber product formulation, vulcanization system and vulcanization temperature design have the greatest impact on the performance of rubber products. Therefore, formulating reclaimed rubber products should be rationally formulated according to the performance requirements of rubber products. In order to obtain the optimum vulcanization temperature and vulcanization time of reclaimed rubber products, , The best number of trials, by increasing or decreasing the amount of vulcanizing agent, accelerant to adjust to obtain the highest comprehensive ratio of tire reclaimed rubber products formula; reclaimed rubber formulations recipes add an appropriate amount of carbon black, calcium carbonate, either Reduce the cost of raw materials, but also improve the wear resistance of recycled rubber products, but the tire reclaimed rubber itself contains carbon black, calcium carbonate and other substances, so the amount needed to reduce its amount.
The use of tire reclaimed rubber as the main raw material for ordinary rubber miscellaneous materials is the best way to reduce raw material costs. Reasonable formula design can fully meet the demand of products. With the continuous development of tire reclaimed rubber production technology, tire reclaimed rubber can not only be used in the production of ordinary rubber products, but also can produce more and more odorless rubber products, environmentally friendly rubber products, under the premise of ensuring quality, significantly reduce the raw materials cost.
