| 常用抗氧剂性能与用途如下。 The properties and uses of commonly used antioxidants are as follows. ①四[β-（3，5-二叔丁基-4羟基苯基）丙酸]季戊四醇酯 也称抗氧剂1010.白色流动性粉末，熔点120～125℃，毒性较低。是一种较好的抗氧剂。聚丙烯树脂中应用较多，是一种热稳定性高、非常适合于高温条件下使用的助剂，制袋机能延长制品使用寿命，另外，也可用于其他大多数树脂中。一般用量不大于0.5%。 (1) Tetra [beta-(3,5-di-tert-butyl-4-hydroxyphenyl) propionic acid] pentaerythritol ester, also known as antioxidant 1010. White fluidity powder, melting point 120-125 C, has low toxicity. It is a better antioxidant. Polypropylene resin is widely used as an additive with high thermal stability and is very suitable for use at high temperature. Bag making can prolong the service life of products. In addition, it can also be used in most other resins. The general dosage is not more than 0.5%. ②β-（3，5-二叔丁基-4-羟基苯基）丙酸十八酯 也称抗氧剂1076。白色或微黄色结晶粉末，熔点50～55℃，无毒，不溶于水，可溶于苯、丙酮、乙烷和酯类等溶剂。可作为聚乙烯、聚丙烯、聚苯乙烯、聚氯乙烯、聚酰胺、ABS和丙烯酸树脂等的抗氧剂。具有抗氧性好、挥发性小、耐洗涤等特性。一般用量不大于0.5%。可作食品包装材料成型用助剂。 (2) Octadecyl beta-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate is also called antioxidant 1076. White or yellowish crystalline powder, melting point 50-55 C, non-toxic, insoluble in water, soluble in benzene, acetone, ethane and esters and other solvents. It can be used as antioxidant for polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyamide, ABS and acrylic resin. It has good antioxidant property, low volatility and washing resistance. The general dosage is not more than 0.5%. It can be used as an adjuvant for food packaging materials. ③1，1，3-三（2-甲基-4-羟基-5-叔丁基苯基）丁烷 也称抗氧剂CA。白色结晶粉末，熔点180～188℃，毒性低，溶于丙酮、乙醇、甲苯和乙酸乙酯。适合于聚丙烯、聚乙烯、聚氯乙烯、ABS和聚酰胺树脂的抗氧剂，制袋机并可用于与铜接触的电线、电缆。一般用量不超过0.5%。 (3) 1,1,3-tris (2-methyl-4-hydroxy-5-tert-butylphenyl) butane is also called antioxidant CA. White crystalline powder, melting point 180-188 C, low toxicity, soluble in acetone, ethanol, toluene and ethyl acetate. It is suitable for antioxidants of polypropylene, polyethylene, polyvinyl chloride, ABS and polyamide resin. Bag making machine can also be used for wires and cables in contact with copper. The general dosage does not exceed 0.5%. ④2，6-二叔丁基-4-甲基苯酚 也称抗氧剂246.白色或浅黄色结晶粉末或片状物，熔点在70℃左右，沸点在260℃左右，无毒。用于多种树脂中，不溶于水，能较好地抑制氧化、热分解和铜的影响，所以，用途广泛。制袋机更适合于食品包装成型用料（聚氯乙烯、聚丙烯、聚乙烯、聚酯、聚苯乙烯和ABS）树脂中。一般用量为0.01%～0.05%。 (4) 2,6-di-tert-butyl-4-methylphenol, also known as antioxidant 246. White or light yellow crystalline powder or flake, melting point at about 70 ~C, boiling point at about 260 ~C, non-toxic. It is used in www.buxiugangsanton.cnwww.buxiugangwanto.cnwww.panshiganzaoj.cnwww.ganzaoji.net.cn www.shengwuzhi.net.cnwww.dingjingxiangjiao.cnmany kinds of resins, insoluble in water, and can better inhibit oxidation, thermal decomposition and the influence of copper, so it is widely used. Bag making machine is more suitable for food packaging materials (polyvinyl chloride, polypropylene, polyethylene, polyester, polystyrene and ABS) resin. The general dosage ranged from 0.01% to 0.05%. |
