中文摘要:
      以丙烯酸(AA)、丙烯酸丁酯(BA)、丙烯酸羟乙酯(HEA)、甲基丙烯酸异冰片酯(IBOMA)和甲基丙烯酸甲酯(MMA)为主要原料,以1,3-二乙烯基四甲基二硅氧烷(DVMS)为改性剂,异丙醇(IPA)为溶剂,偶氮二异丁腈(AIBN)为引发剂,制备丙烯酸树脂预聚体,加入三乙胺中和,加水自乳化制成一系列改性丙烯酸树脂水分散体,进一步制备树脂膜。采用粘度计测试分散体粘度,采用傅里叶红外光谱(FTIR),热重分析仪(TGA),X射线光电子能谱(XPS),扫描电镜(SEM),透射电子显微镜(TEM)等对树脂膜材料进行表征。此外还测试了分散体的贮存稳定性、涂膜吸水率、光泽度等性能。通过测试表明,当DVMS加入量为6wt%时涂膜性能最佳,贮存稳定性较好;涂膜的拉伸强度达到14.3 MPa,断裂伸长率324%;热失重分析T5%分解温度283 ℃;涂膜温度为25 ℃-35 ℃时,涂膜的致密性优异,表现高光泽度,附着性1级,硬度2H。
英文摘要:
      Using acrylic acid (AA), butyl acrylate (BA), hydroxyl ethyl acrylate (HEA), isobornyl methacrylate (IBOMA) and methyl methacrylate (MMA) as the main raw material, 1, 3 - divinyl tetramethyl two siloxane(DVMS)as the modifier, isopropyl alcohol(IPA) as the solvent, azodiisobutyronitrile (AIBN) as the initiator to prepare the acrylic resin pre-polymers. Using triethylamine as the neutralizer. Then add water to make a series of acrylic resin. At last, the resin film was prepared. The viscosity of the acrylate water dispersions were tested by viscometer. The characterization of the cured resin films were analyzed by FTIR,TGA,XPS,SEM,TEM and so on. In addition, the storage stability, the water absorption of the dispersoid and the gloss were also tested. The results show that when the amount of DVMS was 6wt%, the performance of the resin film was improved greatly and the storage stability of the resin was the best. At the same time, the tensile strength of the coating reached 14.3 MPa. The elongation at break was 324%. When the thermal decomposition weightlessness was 5% and the decomposition temperature was 283 ℃. When the coating temperature was 25 ℃-35 ℃, the coating compactness of resin film increased and had high gloss and good adhesion. The adhesion was 1 degree. The hardness was 2H.
