丙烯酸树脂的配方设计原则
丙烯酸树脂及其涂料应用范围很广,因此其配方设计是非常复杂的。基本原则主要遵循以下几点:
Acrylic resin and its coatings have a wide range of applications, so their formulation design is very complicated. The basic principles mainly follow the following points:
1、要针对不同基材和产品确定树脂剂型——溶剂型或水剂型;
1, to determine resin formulations for different substrates and products, solvent type or water type.
2、根据性能要求确定单体组成、玻璃化温度(Tg)、溶剂组成、引发剂类型及用量和聚合工艺;
2. Determine the monomer composition, glass transition temperature (Tg), solvent composition, initiator type and dosage and polymerization process according to the performance requirements.
最后通过实验进行检验、修正,以确定最佳的产品工艺和配方。其中单体的选择是配方设计的核心内容。
Finally, experiments are carried out to check and correct the best product process and formulation. The selection of monomer is the core of formulation design.
