ISOCYANURATE EPOXY COMPOUND HAVING ALKOXYSILYL GROUP, METHOD OF PREPARING SAME, COMPOSITION INCLUDING SAME, CURED PRODUCT OF THE COMPOSITION, AND USE OF THE COMPOSITION

摘要

The present invention relates to an alkoxysilyl-based isocyanurate epoxy compound, a method of preparing same, a composition including same, a cured product of the composition and a use of the composition. A complex including the compound illustrates good heat resistance, particularly, a low coefficient of thermal expansion (CTE), and a high glass transition temperature or Tg. A cured product of the composition illustrates flame retardancy and does not use a separate silane coupling agent. According to the present invention, an isocyanurate epoxy compound including an alkoxysilyl group and an epoxy group at a core; a method of preparing the epoxy compound prepared by epoxidation and alkoxysilylation of a starting material; an epoxy composition including the epoxy compound; and a cured product of the epoxy composition and a use of the epoxy composition, are provided. In the complex of the composition including the novel alkoxysilyl-based isocyanurate epoxy compound according to the present invention, chemical bonding efficiency may be improved when making a chemical bond between the alkoxysilyl group in the epoxy compound and a filler and when forming an epoxy complex through a chemical bond between alkoxysilyl groups in the epoxy compound having the alkoxysilyl group. Therefore, good heat resistance, that is, a low CTE and a high glass transition temperature or Tg may be shown. In addition, the cured product of the composition including the epoxy compound according to the present invention may show good flame retardancy.
