Based on the problems of low viscosity index and the acidity increasing in the lubricating base oil,it has been found that the unstable quality of the crude oil was the root cause to effect on the quality of the base oil by analysis for long time;the low viscosity index and the higher acidity were resulted from the low paraffinicity and the high content of aromatics,cyclane.

针对润滑油基础油相继出现的黏度指数降低、酸值升高等问题，跟踪分析了润滑油基础油质量，认为原油的变化是造成润滑油基础油质量变化的根本原因；基础油组成中烷烃含量降低，芳烃和环烷烃含量上升是其酸值上升和黏度指数下降的内在原因。

As to the high polarity, high boiling point resultant—trimesic acid, the analysis methods of infrared spetrum, gas chromatography-mass spectroscopy, vapour-phase chromatography, acid number titration and so on are seperately used to characterize its property. Infrared spetrum and gas chromatography-mass spectroscopy are used to have a qualitative analysis on the resultant and are compared with the stand diagram. Sulfuric acid-methanol esterification and rapid esterification are used to prepare the trimesic acid trimethyl-ester and have a FID quantitative analysis. So that we make sure the purity of trimesic acid in the resultant and also we have an acid alkali titration on the resultant to get its acid number, in order to verify the purity of trimesic acid in the resultant.

Two-component waterborne polyurethane paint composed of acrylic dispersion and hydrophilically-modified polyisocyanate has fast dry time, good adhesion, flexibility, impact resistance, but poor water and chemical-resistance. The dry time becomes shorter with the increase of glass transition temperature and the decrease of acid value; the gloss of the film decreases with the increases of hydroxyl value, acid value and Tg of emulsion polymer; higher Tg polymer leads to harder film.

将制得的丙烯酸分散体与亲水改性多异氰酸酯组分配制水性双组分聚氨酯涂料，发现漆膜表干和实干比较快，干燥时间随玻璃化温度升高而缩短，随酸值的增加而增加；附着力、柔韧性和冲击强度比较好；光泽随分散体羟值、酸值的增加和玻璃化温度升高而降低；硬度随玻璃化温度升高而升高；较高的酸值使涂料的耐化学品性和耐水性较差，羟值在100mgKOH/g时较好，而酸值应尽可能低。
