On August 7, the Ministry of Industry and Information Technology (MIIT) issued "Technology and Product Catalogs Encouraging Promotion and Application in Petrochemical and Chemical Industries (Second Batch)".
China Rubber Magazine learned that a total of 28 technologies/products were selected, including 3 rubber industry technologies/products, namely "green synthesis technology of TMQ rubber antioxidant with high dimer content", "new synthetic rubber materials for liquid-phase mixing" and "new materials for high-performance rubber products compounding". "High-performance rubber products, rubber mixing technology and equipment".
"Green Synthesis Technology of TMQ Rubber Antioxidant with High Dimer Content" solves the problems of TMQ synthesis, such as high magazine content in condensate, low output of TMQ with high dimer content, low level of automation, and difficult to deal with wastewater, etc., through the development of new type of liquid mis-slip to prepare condensate, preparation of and also in the continuous flow membrane reactor and continuous polymerization reaction, and realizes continuous TMQ synthesis. It has solved the problems of TMQ synthesis, such as high magazine content in condensate, low yield of high dimer TMQ, low automation level, difficult waste water treatment, etc. It has realized the continuous, automated and green production of TMQ, and improved product quality and yield.
This technology has been applied in several TMQ plants, and the product active body content has been increased by more than 10%; the amine impurity has been reduced by 0.8%. Compared with the current one-step technology and two-step technology, wastewater is reduced by 63% and 28%; waste inorganic salt is reduced by 89% and 81%.
"Liquid-phase mixing synthetic rubber materials" is a new rubber material in liquid form for rubber and filler mixing and synthesis, applied in the tire field can improve product energy efficiency, safety, environmental protection, comfort, quietness, etc., to solve the rolling resistance of tires, wet braking performance, abrasion resistance can not be improved at the same time. "The product has been applied in the field of tire production.
The product has been applied in the field of tire production. The main technical and economic indicators are: total polymer in rubber composite ≤75%, residue content after cracking at 550℃ ≥25%, T300/T100 ≥5, silica dispersion grade 10. Compared with the dry process, energy consumption is reduced by 45%.
"High-performance rubber products compounding technology and equipment" includes rubber block continuous mixing, tandem mixing, atomized sputtering wet mixing methods and complete sets of equipment, as well as special mixing equipment such as the rotor of the mixing machine, which can effectively solve the problems of easy aggregation of fillers in the traditional mixing process, difficult to dispersion, high energy consumption, and poor uniformity between batches. It can effectively solve the problems of easy aggregation of fillers, difficult dispersion, high energy consumption and poor batch-to-batch uniformity in the traditional mixing process, realize the high quality of rubber mixing performance and energy-saving mixing process, and enhance the competitiveness of rubber industry.
