摘要
综述了近年来有机硅表面活性剂聚二甲基硅氧烷、聚醚改性聚硅氧烷作为聚氨酯泡沫塑料匀泡剂的研究进展,重点介绍了其主要品种S i─C型聚醚改性聚硅氧烷在无溶剂工艺、催化剂的制备及聚醚配方优化等方面的进展,指出目前提高国产软泡匀泡剂的产品质量是聚氨酯有机硅匀泡剂研究的发展方向。
The recent progress of silicone active agents both polydimethyl siloxane and oxyalkylene siloxane copolymer for polyurethane foams are reviewed. The advance of syntheses Si-C organosilicon foam stabilizers, such as solventless technology, the preparation of the catalyzer, optimization of the technology composition of polyoxyalkylene were introduced especially. It is considered that improving the product quality of soft foam stabilizers will be the development trend of organosilicon foam stabilizers for polyurethane foams presently.
