摘要
不同聚醚由于其下游应用需求不同,对抗氧剂的需求也不同。普通软泡聚醚在发泡应用时由于发泡配方中含水量高,发泡温度比较高,泡沫的烧芯问题是抗氧剂要解决的关键问题,U-pack B7033可以满足应用需求;对于高回弹聚醚,由于其主要应用是汽车领域,除了考虑泡沫的抗烧芯性能外,还要考虑添加的抗氧剂对聚醚及聚氨酯泡沫的醛酮含量以及VOC的影响,U-pack B7170可以满足应用要求;CASE聚醚用抗氧剂除了要考虑聚醚的储存稳定性外,还要考虑下游制备聚氨酯预聚体时的颜色稳定性,U-pack B7522可以满足应用要求。
Different polyether pols have different requirements for anti-aging additives(antioxidants) due to their different downstream application requirements. Flexible foam pols in foaming application due to the high water content in the foaming formula, the foaming temperature is relatively high, the scorching problem of the foam is the key problem to be solved for the anti-aging additive, in this way U-pack B7033 can meet the application requirements. For high resilience pols, since it is mainly used in the automotive field, in addition to the anti-scorching properties of the foam, the effect of the added anti-aging additives is also necessary to be considered on the aldehyde and ketone contents of the polyether and polyurethane foam as well as the VOC content, in this way U-pack B7170 can meet the application requirements. For the CASE pols, in addition to the storage stability of polyether, the color stability should be also considered in the anti-aging additives in this way the prepared polyurethane prepolymer, U-pack B7522, can meet the application requirements.
