中文摘要 | 一系列非離子封鎖型水性PU之合成是以共聚已二酸丁二醇已二醇酯(Copolybutylene hexylene adipate, PBHA)及不同分子量之聚丙二醇(PPG)為多元醇,並以Polyether diol 為非離子型內乳化劑與二環已基甲烷-4,4'-二異氰酸鹽(H12MDI),先進行聚加成反應。首先形成聚氨基甲酸乙酯之預聚合勿,再以封鎖劑丙二酸二乙脂(Diethyl malonate)進行封鎖反應,最後以蒸餾水進行水分散,可獲得固成份25%之封鎖型水性PU分散液。本系列水性PU乳液配合各種加工助劑,如平滑劑、柔軟劑、交連劑及觸媒,以傳統Pad-dry-cure之加工方式,可應用於含纖維素織維織物之防皺整理,其棉織品之抗皺角可達270度以上,強力保持率70 %以上,及游離甲醛含量在80ppm以下。 |
英文摘要 | A series of nonionic blocked aquous polyurethanes (PU) were synthesized from the the polyaddition of 4, 4'-methylenebisCcyclohexyl isocyanate)(H-bsl; 12~bsO;MDI)with polyols such as copolybutylene he xylene adipate(PB-HA), various kinds of polypropylene glycol, and polyether diol(PED) served as an internal emulsifier. The obtained polyurethane prepolymers were then blocked with diethylmalonate and then dispersed with distilled water to af-ford blocked aqueous polyurethane with solid content 25 % . The blocked aqueous polyurethanes were formulated with processing additives such as softener, smoothing agent, crosslinker, and catalyst to achieve wrinkle-resis-tant application for cotton fabric through pad-dry-cure procedure. The wrin-kle recovery angles and strength retention were above 270° and 70 % , re-spectively. The content of free formaldehyde was below 80ppm. |
