有機(jī)化學(xué)聚氨酯論文摘要翻譯
|
|||
|
隨著社會的進(jìn)步和人們生活水平的提高，人們對織物的外觀和穿著舒適度的要求越來越高，因此對織物進(jìn)行功能整理顯得尤其重要。染色后整理使用的功能助劑不僅對織物要有較好的整理效果，如固色、防皺、耐洗、抗靜電、抗紫外線等；而且要求無毒，對環(huán)境無污染。所以尋求高性能且環(huán)保的織物功能助劑始終是染整行業(yè)研究的熱門課題。 本論文研究的主要內(nèi)容：(1)采用異佛爾酮二異氰酸酯、聚乙二醇、聚丙二醇、二羥甲基丙酸、三乙胺、亞硫酸氫鈉等為主要原料合成了系列水性聚氨酯功能助劑并表征其相關(guān)分子結(jié)構(gòu)；(2)采用二甲基二烯丙基氯化銨和N,N-二甲基烯丙基對苯甲酰芐基溴化銨對水性聚氨酯進(jìn)行改性合成了兩種改性水性聚氨酯功能助劑并表征其相關(guān)分子結(jié)構(gòu)；(3)將所合成的系列水性聚氨酯功能助劑應(yīng)用于不同活性染料的染色織物進(jìn)行固色等功能整理并測試了其相關(guān)效果。 研究結(jié)果顯示：(1) 所合成的系列水性聚氨酯功能助劑不含甲醛，確定了合成穩(wěn)定的水性聚氨酯乳液的條件：DMPA用量為4%，中和溫度為40℃，中和度為100%；R值在1.6-2.0之間有利于獲得外觀和穩(wěn)定性較好的乳液。 (2) 根據(jù)所合成的水性聚氨酯功能助劑對織物整理效果的影響，確定了最佳的合成條件：R=2.0，封端劑用量為6.5%，環(huán)氧氯丙烷用量為5.5%，PH=6。 (3) 根據(jù)水性聚氨酯功能助劑的應(yīng)用工藝參數(shù)對織物整理效果的影響，確定了最佳的整理工藝：功能助劑用量4%，烘焙溫度為140 ℃，烘焙時間為1.5min，整理液溫度為50 ℃，時間為30 min，軋余率為100%。 (4) 用合成的二甲基烯丙基氯化銨對水性聚氨酯進(jìn)行改性，確定了適宜的合成條件：n(單體1)：n(單體2)=1:2，引發(fā)劑NBS用量為1%，并確定了其對織物的較優(yōu)整理工藝：功能助劑用量為3%，烘焙溫度為130℃，整理液pH為6，整理液溫度為50 ℃，時間為30 min。 (5) 用合成的N,N-二甲基烯丙基對苯甲酰芐基溴化銨對水性聚氨酯進(jìn)行改性，確定了適宜的合成條件：n(單體1)：n(單體2)=1:2，引發(fā)劑NBS用量為1%。并確定了其對織物的較優(yōu)整理工藝：功能助劑用量為3.5%，烘焙溫度為140℃，整理液pH為6，整理液溫度為50 ℃，時間為30 min。 研究結(jié)果表明，所合成的功能助劑對不同的活性染料染色的織物均有較好的整理效果，而且N,N-二甲基烯丙基對苯甲酰芐基溴化銨季銨鹽改性水性聚氨酯功能助劑具有良好的吸收紫外線功能。 |
