Problems solved by technology

[0003] Traditional rubber additives are mostly powdery chemicals, so there are many problems in use, such as: a large amount of dust, the dispersion of bad smells, toxic volatile substances, etc., which affect safety, hygiene and environmental protection; in addition, some chemicals Poor compatibility with rubber, it is difficult to uniformly disperse and affect the stability of the quality of rubber products. If it is improved by prolonging the kneading time or increasing the kneading temperature, it may affect the increase of the manufacturing process cost or some side reactions of the physical properties of the product
