Latex reclaimed rubber powder is mostly processed from latex wire, waste latex gloves, etc., which has good elasticity, flexibility and certain strength, and can play a role in increasing elasticity and toughening and reducing specific gravity in the production of rubber products. When using natural rubber, styrene-butadiene rubber, butadiene rubber or recycled rubber as raw materials to produce various types of rubber soles, an appropriate amount of latex reclaimed rubber powder can be added to improve the comprehensive performance of the sole and reduce costs.
1. The role of latex reclaimed rubber powder in rubber soles
(1) Elasticity and toughness
Latex reclaimed rubber powder retains the elasticity of latex, and the appropriate amount of latex rubber powder mixed with rubber sole can improve the elasticity and flexibility of the sole, which can quickly restore the original state of the rubber sole after being compressed, maintain good flexibility and bendability in harsh environments such as low temperature, and is not easy to brittle, so as to improve the comfort and stability of people in the process of walking.
(2) Improve abrasion resistance, flexural resistance and aging resistance
Latex reclaimed rubber powder contains a certain amount of natural rubber components, which can give rubber soles good abrasion resistance and flexural resistance; Rubber powder can also be combined with the basic rubber compound in the vulcanization process to further improve the wear resistance and flexural resistance of the sole, and the rubber sole can maintain good performance for a long time in repeated bending and stretching, and is not prone to cracking, deformation and other problems, and improve the aging resistance of the rubber sole.
(3) Reduce costs
Latex reclaimed rubber powder as a resource for the crushing and processing of waste latex products, the price is much lower than that of natural rubber and synthetic rubber, and a certain proportion of recycled latex powder mixed with rubber soles can reduce the amount of raw rubber and reduce the cost of raw materials; Latex rubber powder has a low density, and adding latex rubber powder to rubber soles can also reduce the amount of calcium powder, clay and other fillers, reduce the proportion of products, and further reduce production costs.
2. Which rubber soles can be mixed with recycled latex powder
In actual production, an appropriate amount of latex rubber powder can be mixed in the production of rubber soles of general shoe materials, such as liberation shoes, sports shoes, leather shoes, casual shoes, labor protection shoes and fashion shoes and other rubber soles (including rubber outsoles, midsoles, etc.); The performance requirements of rubber soles and different parts of shoe materials are different, and the dosage of latex rubber powder is different.
3. Latex reclaimed rubber powder in rubber soles adding skills
It is recommended to mix latex reclaimed rubber powder of more than 60 mesh in rubber sole, the higher the fineness of the rubber powder, the larger the specific surface area, and the more uniform dispersion in the rubber matrix, which can effectively improve the wear resistance and flexural resistance of rubber sole. The specific gravity of Hongyun 60 mesh white lightweight latex rubber powder is about 0.6, which has the characteristics of light color, high fineness, small specific gravity, good elasticity and no impurities, and is an ideal raw material for rubber sole elasticity and toughening, and reducing costs.
When rubber soles are mixed with latex rubber powder, you can try to mix 3%-5% of the rubber material first, and gradually increase the mixing ratio of rubber powder through experiments, so as to reduce more costs under the premise of ensuring the performance of rubber soles.
Latex reclaimed rubber powder has good elasticity and flexibility, low price, small specific gravity, the appropriate use of latex rubber powder in rubber soles can not only improve the elasticity, flexibility, abrasion resistance, flexural resistance and aging resistance of the sole, E4LYY108 comprehensive properties, but also effectively reduce the amount of raw rubber and filler, reduce the cost of raw materials and the proportion of products, is an ideal raw material for rubber sole elasticity and toughening, and reduce costs. In the future, Xiaobian will continue to share with you the vulcanization formula and production process points of rubber soles mixed with latex rubber powder.
