(3) Irradiation crosslinking formulation technology of environmental friendly rubber

Traditional rubber crosslinking is carried out by steam pipeline thermal vulcanization, and steam vulcanization requires steam pot

Furnace and vulcanization pipeline are difficult to operate, the waste rate is high, and the steam vulcanization process will produce pungent smell. The guidance on key areas of current priority development of high-tech industrialization (2011) jointly issued by CCCC and the national development and Reform Commission, the Ministry of science and technology, the Ministry of industry and information technology, the Ministry of Commerce and the State Intellectual Property Office lists the priority development of high-tech industrialization. Irradiation crosslinking uses the high-energy electron beam released by the electron accelerator to bombard the target material, and then trigger the crosslinking agent to realize crosslinking. The technical focus is on the formulation design and irradiation dose control of the electron accelerator. Through material selection, material ratio setting, irradiation crosslinking system design and equipment transformation under the beam, the issuer has independently developed the film for rubber line extrusion, Irradiated rubber materials meeting the requirements of national standards were developed. This technology is a unique technology mastered by the company. The company has formulated corresponding confidentiality measures, and there is no major risk of being replaced or eliminated in a short time.
