自干型水溶性醇酸树脂的实验研究(Ⅰ)——合成工艺的研究

THE EXPERIMENTAL RESEARCH INTO AIR_DRYING WATER_BORNE ALKYD RESIN (Ⅰ) RESEARCH OF SYNTHETIC TECHNOLOGY

本文从改进涂料的综合性能和达到室温固化着手，研究了水溶性醇酸树脂的合成工艺，确定了以熔融脂肪酸法来合成水溶性醇酸树脂；同时采用顺酐／偏苯三酸酐代替部分苯酐改性醇酸树脂，通过其三官能团的特性和严格控制工艺条件达到提高醇酸树脂性能的目的，研制了性能较好的自干型水溶性醇酸树脂．

By improving synthetic properties as well as room temperature setting, a detailed research on the synthetic technology of alkyed resin was made, and the technology of melting fatty acid process was used as the synthetic technology of water_borne alkyd resin. At the same time, maleic anhydride /meta_trimellitic anhydride was employed instead of segmentary phthalic anhydride modified alkyd resin. As a result, the properties of water_borne alkyd resin were improved owing to the special features of the three functional groups and the strictly controlled technical conditions. Thus, we have developed air_drying water_borne alkyd resin with good properties.
