Rickshaw tires are mainly bicycle tires and motorcycle tires, and are generally processed from natural rubber as the main raw material; the large use of reclaimed tire rubber in the Rike tread rubber can effectively reduce the cost of raw materials. However, the blind use of reclaimed tire rubber in the tire tread rubber will cause the overall performance of the tread rubber to decrease. In actual production, when using reclaimed tire rubber to reduce the production cost of tire tread rubber, rubber product manufacturers must carefully select rubber raw materials and strictly control the production process.
1. Selection of rubber raw materials for Liche tread rubber
Rigid tire tread rubber has higher requirements for mechanical strength. It is recommended to use high-strength tire reclaimed rubber, such as tread reclaimed rubber with relatively high effective rubber hydrocarbon content; environmentally friendly tire regeneration is recommended when preparing light-colored and colored tire tread rubber 2YLYY224 Glue to avoid discoloration and migration.
Natural rubber and butadiene rubber should be used in conjunction with a large number of tire reclaimed rubber in the tire tread rubber. Natural rubber can better ensure the tensile strength, elasticity, tear resistance and wear resistance of the tread rubber. Further improve the elasticity, wear resistance and cold resistance of the tire tread rubber.
2. Selection of rubber accessories for Liche tread rubber
When a large amount of reclaimed tire rubber is used to prepare tire tread rubber, sulfur vulcanization is generally used to improve the mechanical strength and wear resistance of the reclaimed rubber tread rubber. Carbon black can be used to reinforce the tire tread rubber, and white carbon black is recommended to use tire reclaimed rubber to prepare light/color tire tread rubber; softeners such as pine tar can further improve the processing performance of the reclaimed rubber and the original rubber; When choosing anti-aging agents for light-colored/colorful tire rubber, choose environmentally-friendly anti-aging agents that are pollution-free and non-migrating.
3. Rickshaw tread rubber mixing process skills
When tire reclaimed rubber/natural rubber/butadiene rubber is used together to prepare tire tread rubber, the natural rubber and butadiene rubber are generally fully masticated first, and then the natural rubber and butadiene rubber are combined and pressed, and then the reclaimed tire rubber is added. Mix it. In the rubber mixing process, the accelerator is generally added first, then the reinforcing agent, rubber oil, and finally sulfur. In actual production, the rubber refining time of Liche tread rubber is generally controlled at about 30 minutes. The rubber refining includes rolling, triangle bag and other processes to ensure that the reclaimed rubber and the original rubber, rubber and compounding agents are fully and evenly dispersed, providing for the subsequent production process A better foundation.
Using a large amount of reclaimed tire rubber to prepare tire tread rubber can not only reduce the cost of raw materials (about 30%), but also improve the performance of the rubber material and reduce the pollution of waste tires. In actual production, rubber product manufacturers also need to appropriately adjust the vulcanization process, etc. Later editors will continue to share with you.
