采用实验室自制的功能性硫化剂S-organic等量替代进口的不溶性硫黄OT-20,进行实验室小配合实验及轮胎企业生产大配合实验。在小配合实验中研究了S-organic的抗喷霜特性及硫化特性,在大配合实验中考察其应用效果。结果表明,S-organic的各项性能指标达到甚至超过了进口产品OT-20;且S-organic具有抗高温混炼喷霜特性,混炼胶停放1周,未出现喷霜,含OT-20混炼胶,停放第3天时,出现了喷霜。
The lab-made functional vulcanizing agent S-organic is used to replace the imported insoluble sulfur yellow OT-20 to carry out the experiment of small-scale laboratory and the large-scale cooperation of tire manufacturers. S-organic anti-blooming characteristics and vulcanization properties were studied in the small-scale experiment, and the application effect was investigated in the large-scale experiment. The results showed that the performance of S-organic reached or exceeded that of imported product OT-20. The S-organic had anti-high-temperature mixing and blooming characteristics. The rubber was left for 1 week without blooming, including OT-20 Mixing rubber, parked on the 3rd day, appeared blooming.
