THERMOSETTING RESIN COMPOSITE HAVING IMPROVED THERMAL EXPANSION

摘要

PURPOSE: A thermosetting resin composite is provided to secure the low thermal expansion coefficient, and to improve the dimensional stability and workability by the increase of the temperature. CONSTITUTION: A thermosetting resin composite contains an epoxy resin and an amine curing agent having a naphthalene core. The amine curing agent having the naphthalene core is selected from the group consisting of compound marked with chemical formula 1~5. In the chemical formula 2, R1 is a C1~C10 alkanediyl group. In the chemical formula 3, R2 is a single bond or C1~C5 alkanediyl group. In the chemical formula 4, R1 is the C1~C10 alkanediyl group.
