1,抗衰老剂

1.1身体衰老抑制剂

石蜡蜡通常被用作物理抗衰老剂,可以抵抗臭氧和抗老化。当硫化橡胶时,溶解在其中的橡胶时,溶解的石蜡会在冷却后逐渐迁移到橡胶表面,形成一层密集而柔性的蜡膜,从而在空气中脱离了许多保护型的臭氧,并具有保护性的保护性,并具有适用的保护性,并具有适用的保护性,并在适当的wax中脱颖而出。分子结构(例如羧基,羟基等)。修饰的保护蜡的保护能力比普通保护蜡高1.5〜3倍。通过使用改良的保护蜡可以降低臭氧抑制剂的量。

1.2化学抗衰老剂

合成橡胶加工中使用的主要抗衰老药物是胺和喹啉抗脂肪剂。常见品种是抗衰老4020,4010 NA和RD的抗衰老。这三种抗衰老剂的剂量占中国当前抗雄性剂剂量的80%以上。

有许多萘胺的抗鼻子,例如苯基--甲酰胺胺(抗相A),{1-苯基--苯甲基胺(naphylamine(Antisenders d)。但由于其毒性和毒性和致癌性,因此开始生产的生产,因为它的毒性和致癌性就开始了。

China's anti-aging agent RD has become one of the main anti-aging agents of radial tire rubber, the effective component of the product is 2, 2, 4-trimethyl-1, 2-dihydroxyquinoline dimer, especially dimer anti-aging performance is very good, so should try to improve the dimer content.Anti-aging agent RD heat resistance oxygen aging performance is excellent, copper and other metal ions have a strong inhibition, but resistance to ozone and flexor resistance is poor, and anti-aging agent AW or p phenylenediamine anti-aging agent (anti-aging agent 4020) and other use.Anti-aging agent AW can prevent rubber products caused by ozone crack, especially suitable for dynamic conditions of rubber products used in the rubber material, and anti-aging agent H, D and 4010, can enhance its effectiveness.
