Latex regeneration rubber can replace natural rubber to produce all kinds of rubber products, such as rubber sole, all kinds of rubber hoses, wires and cables, etc. but it is not common to mention latex regeneration rubber sealing ring. Under normal circumstances, the production of sealing ring material, good tightness, heat resistance, cold resistance, corrosion resistance, anti-aging, if in the oil medium, you need extremely high oil resistance and so on. Latex regeneration in these areas of performance is not ideal, so the use of latex regeneration rubber sealing ring does not sound realistic. In fact, latex reclaimed rubber can be used to produce sealing rings, but only a few problems need attention.
1, the latex production of reclaimed rubber sealing ring of "auxiliary": a sealing ring is the most important latex reclaimed rubber can not be used as the main materials used in the production of rubber latex reclaimed rubber, rubber sealing part can be added in the formulation of reclaimed rubber latex ring products in order to reduce the material cost, is the use of recycled rubber latex regeneration glue and other varieties such as three EPDM reclaimed rubber, reclaimed rubber raw rubber or nitrile rubber and other use, improve the processing technology, improve the elastic sealing ring.
2, the latex production of reclaimed rubber sealing ring of the "three plus": in order to improve the processing technology, latex reclaimed rubber seal latex reclaimed rubber sealing ring with improved performance and prolong the service life, need to add the following three substances added in seal latex reclaimed rubber formulation:
(1) adding a certain amount of carbon black in the process of refining, the purpose is to strengthen the filling, not only can reduce the cost of rubber raw materials, but also improve the wear resistance of the sealing ring products, and extend the service life;
(2) latex regeneration need to add the right amount of rubber oil seal rubber production process, rubber oil as softener formulations of reclaimed rubber products, can improve the regeneration of rubber elasticity, flexibility, improve the processing performance of reclaimed rubber, mixing characteristics;
(3) adding certain petroleum resin, increasing viscosity, strengthening and softening.
Latex regeneration rubber can not produce sealing ring, is not generalized, reasonable design of sealing ring formula, latex regeneration glue can also play an important role in the production of sealing ring.
