With the rubber industry, more and more rubber products, including Rubber Accelerators, RubberAntioxidants, Anti Aging Agents, etc., in which rubber antioxidant by the people’s attention.
Antioxidant Definition
◆ phenylene diamine antioxidant
Of benzene diamine antioxidant include the most important class of antioxidant, but also a promising class of antioxidant. The major ones are summarized as follows. N-phenyl-N `- cyclohexyl-p-phenylenediamine or trade names of antioxidant 4010 antioxidant CPPD. This product is white powder, pure white powder. Irritating to skin. Accounting for 1.29, melting point is below 110 ℃, easily soluble chloride, soluble in benzene, ethyl acetate, acetone, insoluble in solvents gasoline, insoluble in water. In the air or sunlight becomes slightly dark, but the protective effect diminished. This product is natural rubber and synthetic rubber antioxidant excellent general-purpose one, especially for natural rubber and styrene butadiene rubber. To heat, oxygen, ozone, light and other factors, aging protection superior performance, is also an excellent form of sustained mechanical stress cracking and flex cracking inhibitor. Of high-energy radiation and the aging effects of copper ions also have some protective effect. AT and than the antioxidant protective effect of antioxidant D are good, single-use protection when you have very good performance, but its antioxidant such as AW, crystalline and with the natural aging of the protective ozone cracking and higher performance. Also with the antioxidant A, D, or other communication
◆ N-phenyl-N `- isopropyl – p-phenylenediamine or trade name Antioxidant 4010NA Antioxidant IPPD.
This product is purple lamellae. Slightly toxic, can cause skin allergies anti-hydraulic. Melting point of not lower than 70 ℃. Soluble oils, benzene, ethyl acetate, carbon tetrachloride, methylene chloride, chloroform, carbon disulfide, acetone, ethanol, insoluble in gasoline, insoluble in water. Storage stability. Sunlight will change color, but does not affect performance. This product is natural rubber, synthetic rubber latex of the universal antioxidant. Ozone cracking, flex cracking particularly good protection performance; also heat, oxygen, light and general aging of the excellent protective agent. Also inhibits the aging changes the role of divalent metal ions, protective properties of natural rubber is more comprehensive than the 4010. This product can be used alone, and antioxidant capacity with AW or wax can reduce the amount of protection but also improve performance. Particular, stay with wax and used to raise the level of anti-static properties of ozone cracking. Low melting point, easily dispersed, the solubility in rubber than 4010 large, blooming of the small, it can increase the amount. Polluting large. Commonly used in the dynamic and static stress under conditions of high use of products. General dosage range is 1 to 4 copies.
Antioxidant effects: it has a protective effect on the oxidation of natural rubber heating, synthetic rubber and buthl benzene, butylnitrile so as it can be used to make white, multicolor, light, transparent rubber products (such as shoes and rubber cloth products). ? It can be easily dispersed in rubber materials. B because of its low toxicity, it can be applied to pharmaceutical or sanitary products, manufacturing and food processing.
Understand the definition and application of rubber antioxidant, a reasonable choice for, and can make people’s physical and mental comfort.
