摘要
传统的丙烯酸树脂与环氧树脂物理共混后易沉降分层,难以体现二者的特性,限制了其应用范围。本研究将环氧树脂和丙烯酰胺进行开环反应,形成聚合性中间体后,再与丙烯腈、丙烯酸及其衍生物、苯乙烯等单体混合,通过自由基溶液聚合,将环氧接枝到含有腈基的丙烯酸树脂上,合成了新型耐化学品性树脂。通过研究,确定了该树脂的最佳合成工艺,讨论了各种因素对树脂性能的影响。结果表明,环氧树脂的接枝及丙烯腈的加入,可明显提高传统丙烯酸树脂的耐化学品性能,使其能够应用于化学品罐的包装等领域。
Traditional physically blending acrylic resin and epoxy resin are easily settled and stratified, making it difficult to show their characteristics and limiting their application as well. Thus polymerizable intermediate was prepared from epoxy resin and acrylic amide, making use of ring-opening reaction between both of them. The resulting polymerizable intermediate was mixed with monomers such as acrylonitrile, acrylic acid and its derivatives, and styrene etc, allowing the grafting of epoxy resin onto acrylic resin containing nitrile via free radical polymerization in solution, generating a novel acrylic resin with good resistance to chemicals. The optimal processes for the synthesis of the resin were established, and the factors influencing the properties of the resin were analyzed. Results indicated that the grafting of epoxy resin and introduction of acrylonitrile contributed to greatly improving the resistance to chemicals of acrylic resin, making it feasible for the acrylic resin to be used in can-packing of chemicals.
