NAPHTHALENE BASED EPOXY DIMER AND METHOD FOR PREPARING THEREOF |
摘要 |
PURPOSE: A naphthalene based epoxy dimer and a manufacturing method thereof are provided to improve thermal expansion property, workability, and packing efficiencies between epoxy resin main chains. CONSTITUTION: A naphthalene based epoxy dimer has two naphthalene based core units represented by chemical formula 1. In the chemical formula 1, the naphthalene based unit 1 and 2 are represented by chemical formula 2-1 or 2-2. The hydroxy group of the chemical formula 1 is reformed as epoxy radical, (meta) acrylate group, vinyl group, allyl group or alkoxy silyl group. A manufacturing method of naphthalene based epoxy dimer having two naphthalene based core unit of the chemical formula 1 comprises the following steps: reacting naphthalene based epoxy dimer at room temperature to 200 deg. Celsius for 10 minutes to 5 hours under the existence of solvent and base in order for dihydroxynaphthalene to be 3-10 equivalent based on 1 equivalent of 1,3- bifunctional propanol; forming dihydroxynaphthalene dimer; and reacting at room temperature to 200 deg. Celsius for 1-24 hours under the existence of base and arbitrary solvent in order for epichlorohydrin to be 4-15 equivalent based on 1 equivalent of dihydroxynaphthalene dimer. [Reference numerals] (AA) Naphthalene unit1; (BB) Naphthalene unit2
