摘要:
通过低聚物形成、种子乳液制备和核壳乳液聚合工艺,制备自交联氟碳聚合物乳液,由实验优化配方和工艺参数.研究结果表明,无皂乳液聚合法制备核壳结构自交联氟碳聚合物乳液的较佳条件是:n(BA)∶n(MAA)=1.0∶1.60,低聚物P(BA/MANa)用量为6%,m(BA)∶m(MMA)=40∶60,自交联单体加量为2%,丙烯酸六氟丁酯用量为15%,反应温度为80℃,引发体系为过硫酸钾与亚硫酸氢钠的混合物.通过FTIR、TEM、MFT、乳胶膜的接触角和吸水率等对产物进行结构表征和性能检测,结果表明,用该方法制备的氟碳聚合物乳液,其成膜稳定性和乳胶膜性能均优于用常规法制备的.
Abstract:
Self-crosslinked fluorocarbon polymer emulsion with core-shell structure was prepared via soap-free emulsion polymerization when the conception of particle design and polymer morphology was adopted.The prepared process involves three steps.The first is the formation of oligomer,the second is the preparation of seeded emulsion,and the third is the preparation of fluorocarbon polymer emulsion with core-shell structure.Main factors,which had an influence on the polymerization technology and the performance of the product,were investigated and optimized.Results show that the optimal conditions for preparing fluorocarbon polymer emulsion are as follows: for preparing the oligomer,mol ratio of BA to MAA is equal to 1.0∶1.60,and pH value is controlled within the range of 8.0 and 9.0;the added amount of oligmer P(BA/MANa) is 6%;mass ratio of BA to MMA is 40∶60;the added amount of self-crosslinked monomer is 2%,the added amount of hexafluorobutyl acrylate is 15%;reaction temperature is 80℃;the mixture of potassium persulfate and sodium bisulfite is used as the initiator.The structure and performance of the fluorocarbon polymer emulsion were tested with FTIR,TEM,MFT and contact angle and water absorption of the latex film.The film-forming stability of the fluorocarbon polymer emulsion and the performance of the latex film,which is prepared with the soap-free emulsion polymerization,are better than the one prepared with the conventional emulsion polymerization.
