EPOXY COMPOUND HAVING ALKOXYSILYL GROUP, PREPARING METHOD THEREOF, COMPOSITION COMPRISING THE SAME AND CURED PRODUCT AND USE THEREOF

摘要

The present invention relates to an alkoxysilyl group epoxy compound, a method for producing the same, a composition including the same, and a hardening material, wherein the compound has excellent heat resistance, particularly exhibits a low coefficient of thermal expansion (CTE) and a high glass transition ascending effect in the composition and/or exhibits excellent flame retardance in the hardened material, and a separate silane coupling agent is not needed. By means of the present invention, provided are: an epoxy compound having a core including an epoxy group and at least one alkoxysilyl group which is an S1 substituent independently selected from the group consisting of Chemical Formula S11 to S15 or an S2 substituent independently selected from the group consisting of Chemical Formula S21 to S25; a method for producing the alkoxysilyl-based epoxy compound produced through the epoxy ring-opening reaction and alkoxysilylation of a start material; an epoxy composition including the epoxy compound; a hardened material of the same; and a use of the same. The hardened material which is a composite of the composition including the novel alkoxysilyl group epoxy compound by means of the present invention has the improved chemical bond of the alkoxysilyl group from the epoxy compound and a filling agent. Coupling and bonding efficiency is also improved when a composite is produced by means of the coupling and bonding of alkoxysilyl groups of the epoxy compound having the alkoxysilyl group. Accordingly, excellent heat resistance properties such as a low CTE and a high glass transition temperature are exhibited in the composite, and/or excellent flame retardance is exhibited in the hardened material.
