Latex reclaimed rubber is an ideal raw material to replace natural rubber and reduce the cost of rubber products. The use of latex reclaimed rubber in the outer rubber compound of common red rubber hose produced with natural rubber / polybutadiene rubber as the main raw material can significantly reduce the cost of raw materials. Reasonable design of the outer rubber compound of red rubber hose containing reclaimed rubber can further improve the comprehensive index of rubber hose. Enjoy a red rubber hose reference formula with latex reclaimed rubber.
1. Formula: 5 parts of cigarette adhesive, 20 parts of latex reclaimed rubber, 20 parts of styrene butadiene rubber, 1 part of sulfur, 0.5 part of accelerator, 1.5 part of zinc oxide, 0.5 part of stearic acid 1jlyy1030, 45 parts of light calcium, 1.5 part of paraffin, 0.5 part of antioxidant, 9 parts of iron oxide red; total: 104.5 parts.
2. rubber compound
When the natural rubber / Latex reclaimed rubber / styrene butadiene rubber are used together to produce the outer rubber of red rubber hose, the addition of latex reclaimed rubber can not only reduce the cost of raw materials, but also improve the plasticity and fluidity of rubber material and reduce the probability of vulcanization reversion. In the actual production, the rubber product manufacturers can increase or reduce the use of latex reclaimed rubber according to the specific requirements of the outer rubber of red rubber hose. It can even completely replace natural rubber with latex reclaimed rubber, which can significantly reduce the cost of raw materials.
3. coordination agent
In order to reduce the production cost of natural rubber / styrene butadiene rubber hose outer layer rubber by using latex reclaimed rubber, rubber manufacturers need to reasonably adjust the type hy and dosage of the compounding agent in the formula. In the vulcanization system, accelerator DM / accelerator TETD / accelerator D can be used together to improve the vulcanization degree and vulcanization rate of the rubber compound; the amount of calcium carbonate should be appropriately reduced with the increase of the amount of latex reclaimed rubber, controlled between 40-50 phr, so as to avoid the problem that the excessive amount leads to the decrease of the mechanical strength of the rubber hose outer layer; physical antioxidant paraffin can be selected for the anti-aging system, which is necessary. Paraffin and microcrystalline wax can be used together to further delay the aging time of rubber hose.
At present, when using latex recycled rubber to reduce the production cost of natural rubber / styrene butadiene rubber red common rubber hose outer layer rubber, the commonly used latex recycled rubber includes white latex recycled rubber and zsj red latex recycled rubber; red rubber hose outer layer rubber toner is generally iron oxide. In the actual production, if the red latex recycled rubber is selected to replace the natural rubber to prepare the red rubber hose outer layer rubber, the rubber product manufacturer can reduce the amount of iron oxide red properly.
Latex recycled rubber is an ideal material to reduce the natural rubber products. When using latex recycled rubber instead of natural rubber to produce rubber products, rubber manufacturers must select appropriate recycled rubber products, reasonably adjust the type and dosage of the mixture in the formula of recycled rubber products, and optimize the comprehensive index of products while reducing the cost.
