Using reclaimed rubber to produce deodorant rubber shoe hard midsole can not only ensure the basic performance of rubber shoes, but also significantly reduce the cost of raw materials; adding a small amount of natural rubber to the rubber shoe hard midsole formula with reclaimed rubber as the main raw material can further optimize the rubber while reducing costs The quality of the midsole reduces the cost of more raw materials. So in actual production, how much natural rubber is added to the reclaimed rubber in the hard midsole formula of deodorant rubber shoes, and how to coordinate the relationship between the various indicators by adjusting the coordination system?
1. Reference formula for hard midsole of deodorant rubber shoes
50 parts of natural rubber, 750 parts of regenerated rubber, 3 parts of zinc oxide, 11 parts of stearic acid, 3 parts of antioxidants, 112 parts of clay, 37 parts of coumarone, 11 parts of accelerator, 9 parts of sulfur, 14 parts of deodorant, total : 1000 copies.
2. Selection of raw materials for reclaimed rubber deodorant rubber shoes hard midsole
When using reclaimed rubber to produce the hard midsole of deodorant rubber shoes, rubber product manufacturers can choose to use latex reclaimed rubber or tire reclaimed rubber according to actual needs. For the production of light-colored or high-performance hard midsoles 2LLYY820, it is recommended to use latex reclaimed rubber (light-colored soles use white latex reclaimed rubber); if you want to reduce more raw material costs, rubber sole processing companies can use tire reclaimed rubber, with effective rubber hydrocarbon content Higher tread reclaimed rubber has better performance.
It should be noted that deodorant rubber shoes are closely related to human health. Rubber products manufacturers must choose environmentally friendly reclaimed rubber or odorless reclaimed rubber to avoid harmful substances that affect human health.
3. Reclaimed rubber deodorant rubber shoes hard midsole coordination system
Reasonable design of hard midsole formula for deodorant rubber shoes can improve product quality and processing technology. When selecting sulfur vulcanization, the accelerator M/DM/D can be used together. The vulcanization speed is fast and the mechanical strength of the vulcanized rubber is high. The vulcanization speed can be better controlled by adjusting the amount of the accelerator D. Solid coumarone resin has multiple functions such as plasticizing, thickening, and strengthening in rubber. Liquid coumarone has better plasticization and viscosity enhancement effect but lower reinforcement; the solid coumarone and liquid coumarone are 1:1: The ratio of 2 is better to strengthen and soften.
In actual production, using a proper amount of sterilization and deodorant in the hard midsole of reclaimed rubber deodorant rubber shoes can achieve good sterilization and deodorization effects. Among them, the steam of α-bromocinnamaldehyde at room temperature is extremely low, and the steam in a closed container Crystals will not be formed again, and various molds, bacteria, yeasts and some pests can be killed during use, and the effect of sterilization and deodorization is remarkable.
When using reclaimed rubber as the main raw material to produce the hard midsole of deodorant rubber shoes, the rubber product manufacturer needs to choose whether to use natural rubber according to the reclaimed rubber index and midsole performance requirements, reasonably control the amount of natural rubber added, adjust the formula appropriately, and ensure that while reducing costs The performance and service life of the hard midsole of deodorant rubber shoes. Later, the editor will continue to discuss with you the processing technology of using reclaimed rubber and natural rubber to produce the hard midsole of deodorant rubber shoes.
