Antioxidant DTPD is a p-phenylenediamine anti-aging agent, a special anti-ozonant for neoprene, which is not only a high-efficiency anti-aging agent for tire industry, but also widely used in various rubber products. Anti-aging agent DTPD anti-ozone, anti-curvature and crack resistance similar to anti-aging agents 4010NA and 4020, far better than anti-aging agents A, D. The anti-aging agent DTPD has good long-term performance, especially in combination with anti-aging agent 4020 or 4010NA1:1, which is the best anti-ozone system for improving tire life. The reason is that the two types of p-phenylenediamine have a synergistic effect, and the antioxidant 4020 or 4010NA provides the necessary short-term protection at an early stage, while the antioxidant DTPD acts as a long-term protection. Since one or two solubilizing groups are introduced on the benzene ring on both sides of the molecular structure of the antioxidant DTPD, the solubility in the rubber is greatly increased, and the blooming property is also much lower, allowing a larger amount in the rubber compound. . Antioxidant DTPD has little effect on vulcanization and scorch because of its small alkalinity, especially because it is the strongest anti-metal toxicant. It has the longest protective effect and is especially suitable for use conditions. Harsh heavy-duty tires, off-road tires, and a variety of radial tires and bias tires. The antioxidant DTPD can also completely change the defects of applying the anti-aging agent 4010NA and 4020 tires to redden.
