Epoxy Acrylate Resin Mica Composite Synthesis

Initially, a UV-curable epoxy acrylate resin was prepared by mixing monomers and reactive dilutants, as listed in Table 1. The resin was homogenously mixed using a homogenizer. The experimental setup is shown in Figure 1. In this procedure, 1 g of KH570 was blended with deionized water and ethanol at a weight ratio of 1:1:20. Following 5-minute hydroxylation at room temperature, the resulting KH570 solution was gradually introduced into a mixture of epoxy acrylate resin and mica dispersion. The mixture was stirred for 1 h at 80 °C. Subsequently, the epoxy acrylate resin and mica powder were accurately weighed and calculated in terms of weight percentage ratios of EPA, EPA/mica 5%, EPA/mica 10%, and EPA/mica 15%, respectively, with the addition of KH570 to ensure proper dispersion.
