| 摘要:利用荧光碳量子点(CDs)和锂皂石协同乳化烯基琥珀酸酐(ASA)Pickering乳液,研究了CDs-锂皂石对ASA乳液性能的影响,并将乳化的ASA Pickering乳液进行纸张施胶应用。结果表明,提高CDs用量,CDs-锂皂石复配颗粒接触角增大,在锂皂石用量0.050 g、CDs用量1.000 g时,CDs-锂皂石乳化的ASA Pickering乳液稳定性最好,乳液粒径最小,并且均为水包油型乳液。激光共聚焦显微镜下观察到CDs-锂皂石吸附在油水两相界面处,形成一层界面颗粒膜,提高了乳液的稳定性。当CDs-锂皂石用量为1%(相对于ASA)、ASA用量为0.2%(相对于绝干浆)进行浆内施胶时,纸张施胶度为73 s,继续提高CDs-锂皂石用量时,纸张施胶度和ASA的水解稳定性提高。 |
| Abstract:The effects of fluorescent carbon quantum dots(CDs) and laponite on the properties of alkenyl succinic anhydride(ASA) emulsions were investigated by synergistic emulsification of ASA Pickering emulsion, a novel ASA paper sizing agent emulsion, with CDs and laponite. The results showed that the contact angle of the CDs-laponite particles decreased with the increase of the amount of CDs or laponite, the ASA Pickering emulsion emulsified by 0.050 g laponite and 1.000 g CDs had the best stability and the smallest emulsion particle size, and all the ASA emulsions prepared were oil-in-water Pickering emulsion. Confocal microscope showed that the CDs-laponite particles were adsorbed at the interface between oil and water and formed an interface particle film, which improved the stability of the emulsion. The paper sizing degree was 73 s when the dosage of ASA was 0.2%(based on dry pulp, wt%) with 1%(based on ASA, wt%) of CDs-laponite. Increasing the amount of CDs-laponite particle, both the paper sizing degree and the hydrolytic stability of ASA were improved. |
