摘要: 针对大豆磷脂加脂剂易氧化造成的皮革性能缺陷问题,考察了没食子酸丙酯(PG)、叔丁基-4-羟基茴香醚(BHA)、特丁基对苯二酚(TBHQ)、生育酚(VE)和2,6-二叔丁基对甲酚(BHT)等5种抗氧化剂对磷脂加脂革在存放、干/湿热和光照等条件下,异味、黄变、六价铬、柔软度等性能的变化。结果表明,5种抗氧化剂都可以提高磷脂加脂革的综合性能,特别是PG和BHA,在3%用量下可以基本解决加脂革的异味、六价铬超标、黄变和柔软性下降等问题,但随着用量的加大,由于抗氧化剂的黄变,导致皮革耐黄变性能的下降。

Abstract: In order to solve the problem of the defects of leather properties caused by the oxidation of soybean phospholipid fatliquor, the effects of five antioxidants, including propyl gallate (PG), tert butyl-4-hydroxyanisole (BHA), tert butyl hydroquinone (TBHQ), tocopherol (VE) and 2,6-di-tert-butyl-p-cresol (BHT), on the odor, surface color(yellow), hexavalent chromium content and softness of leathers with phospholipid fatliquor after storage, dry / wet heat and light treatment were investigated. The results showed that all the five antioxidants could improve the comprehensive properties of fatliquored leather, especially PG and BHA. When these two antioxidants were 3% (based on fatliquor weight), the problems such as odor, over standard hexavalent chromium, yellowing and softness degradation of fatliquored leather could be solved. However, with the increase of dosage, the yellowing resistance of leather decreased due to the yellowing of antioxidants.
