Synthesis of Epoxy Resin Emulsifier and Evaluation of Its lotion Properties
The waterborne epoxy lotion was prepared with epoxy resin E-44 as the main raw material. The effects of emulsifier content on the particle size characteristics, storage stability and centrifugal stability of lotion were studied, and the basic properties of lotion film under the optimal emulsifier content were tested. The results showed that with the increase of emulsifier content, lotion particles gradually migrated to the direction of smaller particle size, and the storage stability and centrifugal stability were gradually improved. When the emulsifier content was more than 18％, the average particle size reduction and stability improvement of lotion would slow down, and the recommended emulsifier content was 18％～24％. When the emulsifier content was 18％, the cured lotion film had a pencil hardness of 3H, flexibility of 1 mm, and adhesion of grade 1, which had good water resistance and acid resistance.
