use | suitable for natural rubber, synthetic rubber and latex this product is a universal antioxidant for natural rubber, diene synthetic rubber, neoprene rubber and base latex. It has a good protective effect on heat, oxygen, flexing and general aging, and is slightly better than the anti-aging agent A. It has an inhibitory effect on harmful metals, but it is weaker than the anti-aging agent. If combined with antioxidant 4010 or 4010NA, the resistance to heat, oxygen, flex and crack, and the resistance to ozone are significantly improved. This product has no effect on the vulcanization speed of natural rubber, nitrile rubber and styrene butadiene rubber, but has a slight delay effect on chloroprene rubber. This product is easy to decompose in dry glue and disperse in water. The solubility of this product in rubber is about 1.5%, and no frost spraying will occur if the dosage does not exceed 1 part. The product is polluting and gradually turns gray-black in sunlight, so it is not suitable for white or light-colored products. It is mainly used to manufacture industrial products such as tires, rubber hoses, adhesive tapes, rubber rollers, rubber shoes, wire and cable insulation layers. Anti-aging agent butyl can also be used as a stabilizer for various synthetic rubber post-treatment and storage, and can be used as a heat-resistant anti-aging agent for polyoxymethylene. The product has a certain irritation to the skin. test chlorate. Organic synthesis. Dye intermediates. Used as rubber antioxidant, lubricant, polymerization inhibitor. |
Production method | 2-naphthol and aniline are condensed at 250 ℃ under the catalysis of aniline hydrochloride. Add 2-naphthol and benzene to the condensation pot to melt, and add aniline hydrochloride for condensation. After the reaction is over, neutralize with sodium carbonate. Excessive aniline is steamed out, then dehydrated and dried under vacuum, and the antioxidant is obtained by slicing, powdering and packaging. Raw material consumption (kg/t)2-naphthol (98.5%) 660 aniline (99.2%) 425 |
