The main purpose

Retardation accelerator for natural rubber, cis-butadiene rubber, isoprene rubber, styrene-butadiene rubber and natural rubber reclaimed rubber. It is very safe at operating temperature. This product is especially suitable for oil furnace carbon black compounds with high alkalinity. , which can make the rubber discolor and cause slight pollution. Mainly used in industrial products such as tires, tapes, rubber shoes, etc., and can also be used in extrusion products.

Specific implementation steps

The 2-thiol base benzothiazole of 500kg is dissolved in ammonia water to form a solution;

The tert-butylamine of 318kg and above-mentioned solution are dropped into oxidation still, stir, add 135kg copper acetate and 15kg lead sulfate;

Feed oxygen, under the condition that temperature is 35 ℃, react 1.5 hours;

The reaction product is filtered with suction, washed with water, dried and sieved to generate rubber auxiliaries NS.
