Many shoe soles manufacturers, especially those who produce transparent, translucent, light-colored and colored sports soles as their main business items, use white latex reclaimed rubber in order to reduce the production cost, which can not only maintain the good comfort of the rubber soles, but also can Significantly reduce the cost of raw materials. Most shoe factories use white carbon black as a filler in the production of rubber soles using white latex reclaimed rubber. Why is white carbon black popular in latex reclaimed rubber soles?
First of all, let us first understand the white carbon: white powder is white powder, or granular or irregular block, tasteless, odorless, high temperature, but also has some flame retardancy and electrical insulation; in the rubber industry The silica used is usually a powdered product and the silica powder added to the latex reclaimed rubber sole requires a higher degree of fineness due to the rubber sole's own needs. White silica as latex reclaimed rubber light-colored soles of the filler, mainly for the following reasons:
1, Compared with the dark-colored bulking agent in the rubber industry, white powdery white carbon black not only does not burden the rubber sole color when used in light-colored latex reclaimed rubber sole, , Translucent rubber soles can also raise the color of the soles, so that the production of reclaimed rubber soles more bright colors.
2, As a common reinforcing filler in rubber industry, silica has significant reinforcing effect, which can obviously improve the wear resistance of light color latex reclaimed rubber sole and improve the wear resistance of latex reclaimed rubber products. Extend the life of rubber soles.
3, white carbon black has a certain degree of moisture resistance and superior adhesion, finished shoes processing, added a white latex rubber latex shoe soles easily re-binding; at the same time silica has waterproof performance, the use of In the process of contact with water once the soles are not prone to "cracking" phenomenon, is not it useful?
4, white carbon black can improve the rubber latex soles tear strength, just to improve the regeneration of their own tear greater defects, improve the physical properties of light-colored rubber soles.
5, latex reclaimed rubber is waste natural rubber, waste natural rubber products, waste latex products as raw materials processed, and its heat resistance, anti-aging properties and other reclaimed rubber slightly weaker, while the silica itself Have good heat resistance, anti-aging properties, light-colored rubber soles by adding the right amount of silica to improve the soles of the heat, anti-aging properties, thereby extending the use of rubber soles.
Reasonable addition of white carbon black in the light latex reclaimed rubber soles can improve product performance and prolong service life, which can be said to be significant. In the actual production, usually 100 parts of latex reclaimed rubber can be added 45-55 parts of white carbon black, the specific amount needs to be determined according to the needs of the soles and latex reclaimed rubber containing plastic decision, different rubber engineers for the white carbon The amount of black habits are also different.
