Use | the strain of aromatic secondary amine antioxidant. For natural rubber, Diene synthetic rubber, Chloroprene Rubber. It is a general-purpose anti-aging agent for reclaimed rubber, and is also used for chloroprene latex. It has a good protective effect on heat, oxygen, flexor, weather aging and fatigue. In chloroprene rubber with anti-ozone aging properties, harmful metals also have a certain inhibitory effect. This product is often used in combination with other antioxidants such as AP,DNP, especially 4010 and 4010N. In the dry glue is easy to disperse, also easy to decompose in water. In the rubber solubility of up to 5%, the amount of 3-4 parts when not spraying Frost. Because of its pollution, migration and the characteristics of dark color under sunlight, it is not suitable for white and light-colored products, mainly used in the manufacture of tires, rubber tubes, adhesive tapes, rubber rollers, rubber shoes, insulation layer of submarine cable, etc. In the plastic industry, the product can be used as a heat stabilizer for polyethylene. Industrial products because of containing 1-naphthylamine and aniline, it is toxic. suitable for natural rubber and neoprene, can be mixed with other antioxidant |
production method | is obtained by condensation of 1-Naphthylamine with aniline at 250 ° C. Under the catalysis of p-aminobenzenesulfonic acid. Aniline, P-aminobenzenesulfonic acid and melted 1-Naphthylamine were put into a condensation pot, and condensation was carried out at 250 ° C., followed by fractional distillation after completion of the reaction. Aniline is distilled under low vacuum into the mixed fraction (applied), and the cut point of the fraction is determined based on the measured freezing point of the fraction. The antioxidant A and the high-boiling mixture were distilled off. The molten antioxidant A is the finished product by cooling the slices and packaging.
