丙烯酸预聚物的参数对改性醇酸树脂的影响

Effects of Parameters of Acrylic Polymer on Modifying Alkyd Resin

用丙烯酸预聚物改性得到的醇酸树脂具有干燥快,耐候性好等特点。建立了醇酸树脂配方设计的通用程序,该程序可用于丙烯酸预聚物改性醇酸树脂的设计。讨论了丙烯酸预聚物的分子量、官能度以及在配方中的比例等对树脂性能参数的影响;明确了丙烯酸预聚物的参数等对改性醇酸树脂的作用。

The alkyd resin modified with acrylic polymer has shorter drying time and better exterior durability than tradi-tional alkyd resin. A general program of design of the compositions of alkyd resin is established. The program can be also used to design the compositions contained carboxyl of reformed alkyd resin. The affects of the molecular weight, the functional degree and the ratio of acrylic polymer on the performances of alkyd resin were discussed in detail. The function of the configuration paramters of the acrylic polymer on the reformed alkyd resin was obtained.
