Rubber shock-absorbing materials are a large class of rubber products, which play the role of shock absorption, noise reduction and shock reduction in mechanical vibration. Natural rubber, synthetic rubber, and emerging recycled rubber can be used in the production of rubber shock absorbing materials; the use of recycled rubber for rubber shock absorbing materials can significantly reduce production costs. So in actual production, when using tire recycled rubber to reduce the production cost of shock-absorbing materials, is it better to use more recycled rubber? How can we further reduce costs while optimizing the performance of shock-absorbing products?
1. Tire regeneration rubber is mostly used for low-damping shock-absorbing materials
The effective rubber hydrocarbon content in the reclaimed rubber of the tire is between 30% and 35%. It has high mechanical strength, abrasion resistance, flex resistance, and low heat generation during use. It is used to produce shock-absorbing materials, and the overall performance of the finished product is good. However, compared with butyl rubber / recycled rubber and nitrile rubber / recycled rubber, the damping coefficient is relatively small, so it is mostly used for the production of low-damping shock-absorbing materials. In general, when using recycled rubber to reduce the production cost of high-damping shock-absorbing materials, butyl recycled rubber is often selected.
2. Application methods of tire recycled rubber in shock-absorbing materials
Due to different performance requirements of shock-absorbing materials in different applications, the application methods of tire recycled rubber in shock-absorbing materials are different. You can use tire recycled rubber alone to produce ordinary rubber shock-absorbing materials, or with natural rubber, styrene butadiene rubber Raw rubber is used together to produce high-quality shock-absorbing materials; a small amount of recycled tire rubber can also be used in the nitrile shock-absorbing 2LLYY0318 material formula to reduce raw material costs.
3. Ways to improve the performance of tyre recycled rubber shock absorbing materials
When using recycled rubber tires to produce shock-absorbing rubber materials, the rubber product formula gives the rubber another life. Rubber product manufacturers can further improve the comprehensive index of recycled rubber shock-absorbing materials by adjusting the formula. The vulcanized rubber vulcanizate after vulcanization using the traditional sulfur vulcanization system has better shock absorption performance and fatigue resistance; choosing a semi-effective vulcanization system or an effective vulcanization system can improve the heat resistance of the vulcanizate rubber damping material. In the reinforcement system, semi-reinforced carbon black and fine particle thermal cracking carbon black can be used in combination to further improve the shock absorption performance and service life of the tire recycled rubber shock absorbing material.
When using recycled tire rubber to reduce the production cost of shock-absorbing materials, rubber product manufacturers still need to pay attention to many aspects. For example, automotive shock-absorbing materials must use environmentally-friendly tire recycled rubber to avoid excessive levels of harmful substances affecting human health. Later editors will continue to share with you various techniques of using tire recycled rubber to reduce the production cost of shock-absorbing materials.
