Latex reclaimed rubber and natural rubber indicators are similar to replace the natural rubber to produce rubber products can reduce the cost of raw materials, but also to ensure the quality of rubber products; but the use of latex reclaimed rubber production of rubber products, if formula design improper reclaimed rubber products, Cracking large, poor tear strength problems. Therefore, the design of latex reclaimed rubber formulations, you need to consider many aspects of the impact factors in order to maximize the advantages of latex reclaimed rubber, to minimize defects.
1, consider the amount of plastic latex reclaimed rubber: plastic reclaimed rubber content of rubber that is, to understand the amount of plastic, you can determine the use of recycled plastic parts. For example: 80% of the latex reclaimed rubber, for example, should replace or partially replace the natural rubber according to the ratio of 1.3: 1. That is, the proportion of latex reclaimed rubber to replace natural rubber is calculated according to the content of gum and the content of effective rubber hydrocarbon. The proportion of latex reclaimed rubber with different rubber content replaces natural rubber is not the same.
2, pay attention to the composition of latex reclaimed rubber itself: The use of latex reclaimed rubber products rubber products, the reclaimed rubber products to consider the moisture content, softener and other content, according to the actual situation of the appropriate adjustments to adjust the curing system curing agent, accelerator Dosage, adjust the amount of softener; In order to improve the defects of latex reclaimed rubber products flex cracking poor, the appropriate increase in the amount of anti-ozone antioxidant; In order to improve the appearance of latex reclaimed rubber products, but also can increase a certain amount of rubber brightener 5% -10%).
3, according to the performance requirements of their own rubber products, such as color, hardness, strength, elongation, tear strength, density, Mooney viscosity, volatility, choose the closest to their own product indicators latex reclaimed rubber, so as to increase the latex Recycled plastic dosage and to the maximum extent possible to ensure the quality of latex reclaimed rubber products.
The use of latex reclaimed rubber instead of natural rubber production of rubber products, must add more testing, get the most reasonable reclaimed rubber formulations. Tire reclaimed rubber, butyronitrile reclaimed rubber, butyl reclaimed rubber, EPDM reclaimed rubber and other products also need to pay attention to the above problems in designing rubber products. Considering the above, we design the best reclaimed rubber product formula, Under the premise of reducing raw material costs, access to greater profits.
