| 中文摘要 | 非離子封鎖型分散系水性PU( NBPUDs )乃是以適合分子量的Polytetramethylene glycol (PTMG),Polyethylene glycol (PEG)等聚醇類為軟質部分,與4,4’-diisocyanato dicyclohexymethane ( H12MDI ) 反應生成分散性PU,利用長EO側鏈的聚二醇酸( Tegomer DS-3117 )做為內乳化劑,並以亞硫酸氫鈉為封鎖劑。此類封鎖型分散系PU不但可以含浸于紡織品之中做為防縮製品而且可以塗佈於織物之中做透濕防水之用。 |
| 英文摘要 | Non-ionic blocked polyurethane dispersions ( NBPUDs ) use polytetram-ethylene glycol ( PTMG ) , polyethylene glycol ( PEG ) , and polypropropy-lene glycol ( PPG ) of appropriate molecular weights as soft segment poly-ol in reactions with 4, 4’-diisocyanato dicyclohexylmethane ( H12MDI ) to get polyurethane dispersions. A polyether polydiol ( Tegomer DS-3117 ) with long EO side chains was incorporated in the polymer chain to serve as an internal emulsifier and sodium bisulfite ( NaHSO3 ) was used as the blocking agent. Blocked polyurethane dispersions can be used not only for textile dipping to get wrinkle-free product but also for textile coating to get water vapor permeability and water-proof purposes. |
