It is obtained by the reaction of accelerator M (2-thiolyl benzothiazole) with cyclohexylamine. The accelerator M is mixed with cyclohexylamine aqueous solution, and the crude product is oxidized by adding sodium hypochlorite dropwise under stirring to separate the solid material, washed with water to neutral, and dried below 75°C to obtain the finished product. Raw material consumption (kg/t) accelerator M(95%) 745 cyclohexylamine (95%) 500
Introduction | N-cyclohexyl-2-benzothiazole sulfamide The trade name is the accelerator CZ. This product is light yellow powder, slightly odor, non-toxic, specific gravity of 1.31~1.34, melting point not lower than 94 ℃, stable storage. The critical vulcanization temperature is 138 ℃, which has the advantages of excellent scorch resistance and fast vulcanization speed. This product has slight discoloration, is sprayed with cream, and has excellent aging resistance. The general dosage is 0.5~2 parts. |
use | rubber vulcanization accelerator CZ, scientific name N-cyclohexyl -2-benzothiazole sulfenamide, is a highly active aftereffect semi-overspeed accelerator with excellent scorch resistance, safe processing and short vulcanization time. Adding alkaline accelerators, such as thiuram and dithiocarbamate, can enhance its activity, suitable for various rubbers, and do not spray cream with slight discoloration. The vulcanized rubber products have strong aging resistance, tensile resistance and tensile strength, and are suitable for manufacturing industrial rubber products such as tires, rubber shoes, cables, etc. Suitable for the use of furnace black rubber, such as natural rubber, butyl rubber, isoprene rubber, styrene butadiene rubber, nitrile rubber, EPDM rubber, etc., which is characterized by excellent scorch resistance and vulcanization time Short, no frost spraying, aging resistance, heat resistance, crack resistance, and wear resistance. It can be used as a vulcanization accelerator alone or in combination with other accelerators such as D, DT, TT, TS, etc. Used to prepare tires, tapes, cables, hoses and other general industrial supplies. is an excellent aftereffect accelerator, suitable for rubber products such as natural rubber, synthetic rubber and tires one of the commonly used aftereffect accelerators. It is suitable for the use of furnace black rubber, and has the advantages of excellent scorch resistance and short vulcanization time. Can be used in natural rubber, recycled rubber, diene synthetic rubber, especially suitable for styrene butadiene rubber. It can be used alone or with accelerators D,DT,TT,TS, etc. Because of its bitter taste, it cannot be used in food-related products. Slight discoloration, no frost spraying, excellent aging resistance of vulcanized rubber. Mainly used in tires, rubber shoes, rubber hoses, tapes, cables, general industrial products, etc. The product is low in toxicity. is an excellent aftereffect accelerator, suitable for natural rubber and synthetic rubber, and can improve the physical and mechanical properties of rubber products CZ is a highly active aftereffect accelerator with excellent scorch resistance, safe processing and short vulcanization time. The promotion effect is very strong when the vulcanization temperature is above 138 ℃. It is often mixed with WIlLING TMTD, WIlLING DPG or other alkaline accelerators to cooperate with the second accelerator. Alkaline promoters such as thiuram and dithiocarbamate can enhance their activity. It is mainly used to manufacture industrial rubber products such as tires, rubber hoses, rubber shoes, cables, etc. |
