With the continuous development of the rubber industry, the demand for parallel drive rubber belts is also increasing. As one of the main raw materials of parallel drive rubber belt, the quality and performance of tread reclaimed rubber directly affect the service life and performance of parallel drive rubber belt. Let's introduce the formula and precautions for the production of parallel drive rubber belts for tread recycled rubber.
First, the tread regeneration rubber produces the vulcanization formula of parallel drive rubber belt
Hongyun tread recycled rubber 40kg, 100% black latex recycled rubber 10kg,standard natural rubber 5kg, N330 carbon black 5kg, light calcium carbonate 10kg, Pine tar 1.8kg, paraffin 0.25kg, stearic acid 0.4kg, activated zinc oxide 0.7kg, RD antioxidant 0.15kg (if the viscosity is too large, polyethylene glycol 0.4kg can be added), CZ accelerator 0.15kg, DM accelerator 0.15kg, TMTD accelerator 0.05kg, sulfur 0.5kg; vulcanization temperature 145 °C, vulcanization time is determined according to thickness.

Second, the precautions for the production of parallel transmission rubber belts of tread recycled rubber
In the production of parallel drive rubber belts, the choice of raw materials is very important. According to the use requirements of parallel drive rubber belts, appropriate raw materials should be selected to ensure the quality and performance of parallel drive rubber belts. If you need to work in a high temperature environment, you can adjust the formula for EPDM regeneration rubber and tread reclaimed rubber; If you need good tear resistance, you can add a certain amount of styrene-butadiene rubber.
In the production of parallel transmission rubber belts, the dosage of compound should be adjusted according to the specific situation. If the amount of compound is too much, it may cause the hardness of the tread regeneration rubber to be too large, which will affect the service life of the parallel drive rubber belt; If the amount of compound is too small, it may cause insufficient strength of tread regeneration rubber and affect the bearing capacity of parallel transmission rubber belt.
When producing parallel drive rubber belts, the selection and dosage of filling materials should be adjusted according to the specific situation. If the selection and dosage of filling materials are improper, it may cause the quality and performance of the parallel drive rubber belt to not meet the requirements, which will affect the service life of the parallel drive rubber belt. In order to improve the bearing capacity and high and low temperature resistance of parallel transmission rubber belt, a certain amount of filling material needs to be added. Among them, the most commonly used filling materials include steel wire, fiber, triangle glue, etc. Steel wire can improve the bearing capacity and strength of tread recycled rubber; Fibers can improve the flexibility and fatigue resistance of tread regeneration rubber; Triangular adhesive can improve the high and low temperature resistance and compression resistance of tread regeneration rubber.
The formula and precautions for the production of parallel drive rubber belts with tread recycled rubber directly affect the quality and performance of parallel drive rubber belts. In the production of parallel drive rubber belts, reasonable material selection and formula should be carried out according to specific conditions, and attention should be paid to the control of the production process to ensure the service life and performance of parallel drive rubber belts.
