以市售立邦水性涂料作为研究对象,溶剂水作为变量因子。配制不同水料比的涂料系列样品,分别用FTIR/ATR、FTIR/漫反射光谱表征湿料、涂膜的微观结构特征,湿料抽滤得到的固型物用FTIR/漫反射光谱表征。分析其官能团变化情况,研究施工过程,溶剂对涂膜的影响。结果显示:随着加水量的增加,湿料的FTIR/ATR光谱中,1727 cm -1对应的羰基吸收峰,逐渐转为肩峰,871 cm -1吸收峰发生蓝移,峰强度逐渐减弱;涂膜的漫反射红外图谱,3400 cm-1的-O H吸收峰、3030 cm-1不饱和-C H吸收峰强度逐渐变弱,2962和2871 cm -1的甲基和亚甲基的吸收峰强度逐渐增强,2516 cm-1吸收峰位移至2603 cm-1形成肩峰,1647 cm-1吸收峰逐渐位移至1455 cm -1,1107 cm -1对应的C-O伸缩振动吸收峰发生红移。在水性涂料施工过程中,溶剂水与涂料分子间存在相互作用,对涂层分子中电子云的密度分布有显著的影响,此结果对涂料的生产及施工有参考意义。
以市售立邦水性塗料作為研究對象,溶劑水作為變量因子。配製不同水料比的塗料繫列樣品,分彆用FTIR/ATR、FTIR/漫反射光譜錶徵濕料、塗膜的微觀結構特徵,濕料抽濾得到的固型物用FTIR/漫反射光譜錶徵。分析其官能糰變化情況,研究施工過程,溶劑對塗膜的影響。結果顯示:隨著加水量的增加,濕料的FTIR/ATR光譜中,1727 cm -1對應的羰基吸收峰,逐漸轉為肩峰,871 cm -1吸收峰髮生藍移,峰彊度逐漸減弱;塗膜的漫反射紅外圖譜,3400 cm-1的-O H吸收峰、3030 cm-1不飽和-C H吸收峰彊度逐漸變弱,2962和2871 cm -1的甲基和亞甲基的吸收峰彊度逐漸增彊,2516 cm-1吸收峰位移至2603 cm-1形成肩峰,1647 cm-1吸收峰逐漸位移至1455 cm -1,1107 cm -1對應的C-O伸縮振動吸收峰髮生紅移。在水性塗料施工過程中,溶劑水與塗料分子間存在相互作用,對塗層分子中電子雲的密度分佈有顯著的影響,此結果對塗料的生產及施工有參攷意義。

borne paint was studied in the article in which the solvent water was regarded as a variable factor .A series of paint samples with different percentage of water were configured before observing their storage performance and microstructures by u-sing Fourier-transform infrared (FTIR) ATR (attenuated total reflection ) spectroscopy and diffuse reflectance (DF) FTIR spec-troscopy .The effects of construction process and solvent water on the coating film were examined through analyzing the changes of internal functional groups before and after coating .The results indicated that as the amount of solvent water was increased , the characteristic peak of νC in 1 727 cm -1 turned into acromion ,the absorption peak in 871 cm-1 was blue shifted ,the inten-sity of the peak of hydroxyl (νOH ) in 3 400 cm-1 and unsaturated absorption peak of ν-CH in 3 030 cm-1 gradually weakened ,the absorption peaks strengths of ν-CH3 and ν-CH2 in 2 962 and 2 871 cm-1 increased ,respectively .The absorption peak in 2 516 cm -1 was shifted to 2 603 cm -1 then form the acromion ,the absorption peak of 1 647 cm-1 gradually changed to 1 455 cm-1 ,the stretching vibration absorption peak of νC- O in 1 107 cm -1 was red-shifted .During the coating process of paint ,the solvent water and paint molecules interacted with each other ,having a significant impact on the electron cloud density distribution of the paint molecules .The results obtained in the article have an important significance for the production and construction of paint .
