一种纺织浆料用的复合变性接枝淀粉及其制备方法

Composite modified graft starch for textile slurry and preparation method thereof

Abstract

本发明系一种生产接枝淀粉的配比及制备方法,一种纺织浆料用的复合变性接枝淀粉,配比为以下重量份的原料:醋酸酯淀粉900、酒精80-100、丙烯酰胺40、丙烯酸10、醋酸乙烯40、片碱5、复合催化剂0.2-0.5;所述醋酸酯淀粉的粘度要求:L:4.0-8.0mPa.S、M:8.1-12.0mPa.S、H:12.1-16.0mPa.S、取代度:0.10±10%。本发明在国内首次采用少量酒精溶剂相生产,解决了以下两个问题:不用水资源,没有废水排放处理。三元混合单体在酒精溶剂条件下,接枝在淀粉大分子上。大大改善了淀粉浆的浆膜性能,满足纺织厂家对高支涤棉品种的上浆需求,替代PVA环保上浆。
The invention discloses a proportioning and preparing method for producing graft starch and particularly relates to composite modified graft starch for textile slurry. The composite modified graft starch for the textile slurry comprises the following raw materials in parts by weight according to proportion: 900 parts of acetate starch, 80-100 parts of alcohol, 40 parts of acrylamide, 10 parts of acrylic acid, 40 parts of vinyl acetate, 5 parts of caustic soda flakes, and 0.2-0.5 part of composite catalyst; and the requirements on the viscosity of the acetate starch is that L (Low Viscosity) is 4.0-0.0mPa.S, M (Middle Viscosity) is 8.1-12.0mPa.S, H (High Viscosity) is 12.1-16.0mPa.S, and the degree of substitution is 0.10+/-10%. According to the invention, a small amount of alcohol is adopted for production for the first time in China, and two problems to be solved on no utilization of water resources and no wastewater emission and treatment are solved. Ternary mixed monomers are grafted onto starch macromolecules under the condition of the alcohol solvent. Therefore, the serous coat performance of starch slurry is greatly improved, the requirements of textile manufactures on the starching of high-count polyester/cotton varieties, and the composite modified graft starch can replace PVA (Polyvinyl Acetate) to perform environment-friendly starching.
