The butyl reclaimed rubber processed from waste butyl inner tube retains the basic performance characteristics of butyl rubber, has the characteristics of good air tightness, heat resistance, ozone resistance, and chemical resistance. It can replace the appropriate ratio of butyl raw rubber to produce cost-effective rubber. Products. Compared with butyl rubber, although the mechanical strength of butyl reclaimed rubber is lower, the product price, processing performance and damping performance are better than butyl virgin rubber, so it has a wide range of applications in the rubber product industry.
1. Low product price
At present, the price of butyl reclaimed rubber on the market is about 6000-7000 yuan/ton, the price of butyl rubber is generally above 13000 yuan/ton, and the price of some brands of butyl rubber has exceeded 25000 yuan/ton. From the price point of view, butyl reclaimed rubber 2YLYY810 has significant advantages over butyl virgin rubber, and is an ideal raw material to replace high-priced butyl virgin rubber to produce rubber products and reduce raw material costs. In actual production, proper adjustment of rubber product formula can solve the problem of low mechanical strength of butyl reclaimed rubber.
2. Good process performance
Butyl rubber has slow vulcanization speed, poor mutual adhesion, and poor compatibility with other rubbers. Compared with butyl rubber, butyl reclaimed rubber has been significantly improved in terms of plasticity, fluidity, vulcanization performance, and compatibility. Taking natural rubber as an example, blending butyl reclaimed rubber with natural rubber can not only improve the mechanical properties of the vulcanized rubber, but also improve the original poor processing performance of butyl rubber and prepare rubber products with better performance.
3. Excellent damping
There are two methyl groups in the monomer molecules of butyl rubber, the elastic hysteresis is relatively large, and it has obvious damping effect. After the butyl reclaimed rubber is desulfurized, the internal cross-linking network is severely damaged, and part of the main rubber molecular chain is broken, so the relative molecular weight is reduced.It can be seen that butyl reclaimed rubber has better damping performance than butyl virgin rubber.
When the butyl reclaimed rubber processed from waste butyl inner tubes replaces butyl raw rubber in a suitable ratio to produce rubber products, it can not only reduce the cost of raw materials, but also improve the processing performance of the rubber. It is widely used in rubber inner tubes, vulcanized bladders, and airtightness. Products such as layers, damping and shock-absorbing blocks, anti-virus appliances, inner tube valve cores, anti-corrosion products and heat-resistant conveyor belts are in production. The editor has the opportunity to continue to share with you the specific application of butyl reclaimed rubber in various rubber products.
