摘要
研究了硅氧烷 聚醚共聚物匀泡剂的结构组成对低密度微孔聚氨酯鞋底料性能的影响 ,介绍了新型匀泡剂DC 30 4 2及DC 30 4 3在低密度鞋底料中作用 ,其中DC 30 4 2可改善泡孔结构及制品表观质量 ,而DC 30 4 3具有改善尺寸稳定性的作用 ,两种复配可得到满意的效果。还介绍了催化剂Dabco 10 2 7及Dabco 10 2 8与现有催化剂复配使用可缩短脱模时间或延长乳白时间。
The effect of chemical structure of siloxane oxyalkylene copolymer stabilizer on the processing performances of low density microcelluar polyurethane sole material was studied.The application of the new stabilizers DC3042 and DC3043 in the sole materials were introduced. DC3042 can improve celluar structure and surface quality of the product, and DC3043 can improve the dimensional stability.When they used in combination,satisfying result can be given.The catalyst Dabco 1027 and Dabco 1028 were also introduced.When one of the two catalysts combine with an existing catalyst,either demoulding time of the system can be shortened,or the cream time can be prolonged.
