| 中文摘要: |
| 以马来酸酐、聚乙二醇1000、氯磺酸和氢氧化钠为原料制备了反应型乳化剂马来酸聚乙二醇酯硫酸钠(MP),然后以MP、苯乙烯、丙烯酸丁酯、丙烯酰胺和甲基丙烯酰氧乙基三甲基氯化铵为原料,以过硫酸铵为引发剂,制备了苯丙表面施胶剂。以FT-IR和TEM对合成的表面施胶剂进行了结构表征,FT-IR分析表明苯丙表面施胶剂具有预期的共聚物结构；TEM分析显示其乳液微粒呈球形,微粒直径约为145 nm。对比自制苯丙表面施胶剂和十二烷基苯磺酸钠(SDBS)/OP-10形成的乳胶膜的耐水性(自乳胶膜形成后15天测试2种乳胶膜的吸水率分别达到19.1%和44.2%)可知,自制苯丙表面施胶剂形成的乳胶膜具有很好的耐水性。与未施胶纸及采用市售产品和进口产品进行表面施胶的双胶纸相比,利用自制苯丙表面施胶剂和表面施胶淀粉复配对双胶纸进行表面施胶后的纸张的抗水性能和强度性能明显提高。 |
| Abstract: |
| Sodium sulphate of polyethylene glycol esters maleic acid(MP) was prepared from materials of maleic anhydride, polyethylene glycol 1000, chlorosulfonic acid and sodium hydroxide, then styrene-acrylate(SA) surface sizing agent was prepared by using MP, styrene(St), butyl acrylate (BA), acrylamide(AM) and methacryloxyethyltrimethyl ammonium chloride(DMC) as materials, ammonium persulfate as initiator. The structural and performance properties of the SA were characterized by FT-IR and TEM. The experimental results showed that CMC values of MP was approximately 0.24 g/L, γCMC values was about 31.2 mN/m. FT-IR and TEM analysis showed that SA had expected copolymer structure, SA emulsion particle was spherical structure, particle diameter was 145nm or so. Water resistance of the film formed by SA was better than that of SDBS/OP-10. Water absorption rates of the films formed by SDBS/OP-10 and SA were 44.2%and 19.1% respectively after 15 days. The application experiment on offset printing paper with SA and starch mixture showed that water resistance and strength performance of sized paper increased significantly compared with unsized paper, the Cobb value, surface strength and folding strength and breaking length were superior to that of commercial products and imported products. |
