| 中文摘要: |
| 在H2O2-FeSO4双组分氧化还原体系中，以壳聚糖为主链，以苯乙烯（St）、丙烯酸丁酯（BA）、N-羟甲基丙烯酰胺（HMAM）和二甲基二烯丙基氯化铵（DMDAAC）为主要单体，通过无皂乳液聚合制备了壳聚糖接枝苯丙共聚物乳液，并将其用作文化用纸的表面施胶剂，通过红外光谱（FT-IR）、静态接触角和扫描电子显微镜（SEM）对壳聚糖接枝苯丙共聚物乳液进行了结构和性能表征。结果表明，壳聚糖接枝苯丙共聚物乳液较佳的合成条件为:m(单体)/m(壳聚糖)＝25，m(过硫酸钾)/m(壳聚糖)＝3，m(FeSO4)/m(H2O2)=0.03，HMAM用量6%（对乳液质量），m(St)/m(BA)＝2.5；壳聚糖接枝苯丙共聚物乳液可提高文化用纸的施胶度、印刷表面强度、耐破度和抗张强度。 |
| Abstract: |
| The chitosan graft copolymer used as surface sizing agent was prepared by soap-free emulsion polymerization with styrene(St), butylacrylate(BA), N-hydroxymethyl acrylamide(HMAM) and dimethyl diallyl ammonium chloride (DMDAAC) as major monomers in oxidation-reduction initiator system. The copolymer was characterized with infrared spectrum(FT-IR), static contact angle and SEM. The optimum synthesis conditions are as follows: m(monomer)/m(chitosan)=25, m(St)/m(BA)=2.5, m(KPS)/m(chitosan)=3.0, m(FeSO4)/m(H2O2)=0.03, and HMAM dosage 6%. The application experiment results demonstrated that when the dosage of surface sizing agent is 0.4%, the paper can achieve the best performance. |
