Problems solved by technology

Since the polarity of natural rubber is relatively poor, and most of the reinforcing materials are polar materials, all reinforcement treatment methods need to face the problem of: while improving the mechanical strength of natural rubber, solve the problem of the relationship between the reinforcing material and natural rubber. capacitive problem
However, this patent does not improve the compatibility between the reinforcing material and the natural rubber latex material, and the improvement of mechanical properties is limited
