Use
Rubber vulcanization accelerator CZ, scientific name N-cyclohexyl-2-benzothiazole sulfenamide, is a highly active after-effect semi-overspeed accelerator with excellent scorch resistance, safe processing and short vulcanization time.The addition of alkaline accelerators, such as thiuram and dithiocarbamate, can enhance its activity. It is suitable for all kinds of rubber, with slight discoloration and no blooming. The vulcanized rubber products have aging resistance, strong tensile strength, and strong constant elongation, and are suitable for the manufacture of industrial rubber products such as tires, rubber shoes, and cables.
It is suitable for the use of furnace black rubber, such as natural rubber, butyl rubber, isoprene rubber, styrene-butadiene rubber, nitrile rubber, EPDM rubber, etc. It is characterized by excellent scorch resistance and short curing time. , No frosting, anti-aging, heat-resistant, crack-resistant and wear-resistant products.
It can be used alone as a vulcanization accelerator, or it can be used in combination with other accelerators such as D, DT, TT, TS, etc. It is used to prepare general industrial supplies such as tires, tapes, cables, and hoses. It is an excellent after-effect accelerator, suitable for rubber products such as natural rubber, synthetic rubber and tires. It is one of the commonly used after-effect accelerators.
It is suitable for the use of furnace black rubber, which has the advantages of excellent scorch resistance and short curing time. It can be used for natural rubber, regenerated rubber, diene synthetic rubber, especially for styrene-butadiene rubber. It can be used alone or in combination with accelerators D, DT, TT, TS, etc. Due to its bitter taste, it cannot be used in food-related products. Slight discoloration, no frosting, excellent aging resistance of vulcanizate. Mainly used for tires, rubber shoes, hoses, tapes, cables, general industrial products, etc. The product is low toxicity.
It is an excellent after-effect accelerator, suitable for natural rubber and synthetic rubber, and can improve the physical and mechanical properties of rubber products CZ is a highly active after-effect accelerator with excellent scorch resistance, safe processing and short curing time. The promotion effect is very strong when the vulcanization temperature is above 138℃. Often combined with WIlLING TMTD, WIlING DPG or other alkaline accelerators as the second accelerator. Alkaline accelerators such as thiurams and dithiocarbamates can enhance their activity. Mainly used in the manufacture of tires, hoses, rubber shoes, cables and other industrial rubber products.
Production method It is obtained by the reaction of accelerator M (2-thiol benzothiazole) and cyclohexylamine. Mix the accelerator M with the aqueous solution of cyclohexylamine, add sodium hypochlorite dropwise with stirring to obtain the crude product, separate the solid material, wash with water until neutral, and dry at below 75°C to obtain the finished product. Raw material consumption (kg/t) Accelerator M (95%) 745 Cyclohexylamine (95%) 500
