China's rubber additive industry has continued to grow steadily for many years, but there are still some gaps in the development of cleaner production technology and the supply and demand of a few functional products. According to the key technologies and common technologies that need to be urgently addressed in the development of the industry, the Rubber Additives Professional Committee of the China Rubber Industry Association has declared to the Ministry of Science and Technology that the "rubber additives clean production process and special functional product development" "Eleventh Five-Year Plan" national science and technology support plan project. mainly include:
(1) Development of oxygen oxidation process route of promoter NS
(2) NS wastewater treatment and comprehensive utilization of water resources
(3) Development of production technology for 10,000-tonne high thermal stability insoluble sulfur
(4) Development of production technology for 10,000-ton pre-dispersed rubber additive products
The completion of the above-mentioned projects will play an important demonstration role in the cleaner production process technology of China's rubber additives. At the same time, it will form a large-scale production capacity of high thermal stability insoluble sulfur and rubber homogenizer products, and gradually realize self-sufficiency. After the project is completed, all varieties of rubber additives for radial tires in China will be self-sufficient and not subject to import restrictions.
