醋丁纤维素光亮剂的研制

The Preparation of CAB Glossy Agent

本文在比较了醋丁纤维素（ＣＡＢ）与硝化棉性能的基础上，以柔韧性、耐光性好的聚丙烯酸酯（ＰＡＥ）为改性剂，ＣＡＢ与ＰＡＥ通过半—互穿网络共混，研制出ＣＤ耐光光亮剂，包括ＣＤ１溶剂型、ＣＤ２水乳型两个产品。对研制过程中遇到的问题，如ＰＡＥ与ＣＡＢ相容性、溶剂、乳化剂的选择等进行了讨论。表１。

Abstract Based on the comparison of the properties of cellulose acetate butyrate(CAB) and cellulose, CD light-fast glossy agents are obtained through the combination of semi-interpenetrating polymer networks (semi-IPNs) of CAB and polyacrylic ester (PAE) which acts as a modifier and has good lightfastness and flexibility. Thus, CAB and PAE are semi-IPNs combined under nitrogen. In the reaction, solvents at the medium boiling point are progressively added to gain CD-1, while CD-2 is got following the steps as; the removal of the solvents at low boiling point in the CD solution, addition of the solvents of <1 compounding density, and then the adding of the emulsifier compounded by nonion and anion in high-speed shearing machine to produce the emulsion.
