Technical Field

[0001] This invention relates to the field of chemical production technology, and in particular to a production apparatus and preparation method for polyurethane modified silicone oil. Background Technology

[0002] In the finishing processes of textile and leather materials, the raw materials themselves are often rough, stiff, and uncomfortable to wear. Therefore, hand-feel finishing is necessary to improve the comfort of the finished product. Initially, hand-feel agents were mainly aliphatic (non-silicone), primarily cationic, but also including nonionic, anionic, and amphoteric types. Cationic softeners offer the best softening properties and are typically available in emulsion, thick paste, high-concentration softening oil, and waxy flakes / beads. Later, with the discovery and application of the superior properties of functional organosilicon polymers, the proportion of modified organosilicon polymers in hand-feel finishing agents has increased year by year, becoming a very popular type of hand-feel finishing agent.

[0003] Polyurethane-modified silicone oil can be converted into a stable microemulsion state by adding emulsifiers or directly adding water, and then used as an end product. The ratio of silicone oil to water or surfactant can be adjusted according to the specific application requirements for silicone oil emulsion particle size and storage and application stability.
