Latex recycled rubber is an ideal raw material to reduce the cost of rubber joints instead of natural rubber. When using latex recycled rubber to produce rubber joints, rubber product manufacturers can further improve the performance and service life of rubber joints by adjusting the formula of rubber joints and production process conditions. So in the actual production process, which compounding agents can be used for the rubber joint formula containing latex recycled rubber, and what problems should be paid attention to during the process of rubber mixing and vulcanization?
3. Tips for selecting rubber joint compound containing latex recycled rubber
For rubber products, reasonable selection of the types of compounding agents in the formulation and controlling the amount of compounding agents can significantly improve the comprehensive indicators and performance of rubber products. When using latex recycled rubber alone or combined with natural rubber, styrene-butadiene rubber, etc. to produce rubber joints, rubber product manufacturers can choose sulfur vulcanization, and use appropriate amount of high wear-resistant carbon black, semi-reinforced carbon black 1JLYY1219, and adjust the vulcanization by vulcanization accelerator Speed and vulcanization safety, moderate amount of rubber oil softens and plasticizes, and a small amount of antioxidant can extend the service life of rubber joints.
4. Techniques for refining rubber joints for the production of latex recycled rubber / raw rubber
When using latex recycled rubber / virgin rubber to produce rubber joints with rubber, in order to ensure that the compounding agent is evenly dispersed in the rubber compound, rubber product manufacturers can try to add certain compounding agents in the formula in the form of master batch or paste to ensure that the compounding agent is uniform. Dispersion, the temperature of the mixer should not be too high during the mixing.
Latex recycled rubber and natural rubber, styrene-butadiene rubber and other general-purpose rubbers used to produce rubber joints need to strictly control the vulcanization temperature, vulcanization time, vulcanization pressure, etc. The vulcanization temperature should not be too high; Reasonably design the rubber joint mold and clean the mold in time; pay attention to the cleaning of the production workshop Degree, etc. At present, latex recycled rubber is widely used in rubber joints. Some rubber joints can also use latex recycled rubber completely, or use latex recycled rubber with tire recycled rubber to reduce more raw material costs.
When using latex recycled rubber to reduce the production cost of rubber joints, rubber product manufacturers can choose the appropriate latex recycled rubber according to the actual performance requirements of the rubber joints and the manufacturer's cost budget, reasonably control the amount of latex recycled rubber, and appropriately adjust the formula of rubber joints containing latex recycled rubber. The type and amount of the intermediate compounding agent can increase the amount of latex recycled rubber as much as possible under the premise of ensuring the quality of the rubber joints, and reduce more raw material costs.
