Title:
FIRE-RESISTANT PHOSPHORUS-CONTAINING EPOXY RESIN COMPOSITION AND HARDENED SUBSTANCE OBTAINED THEREBY
Document Type and Number:
WIPO Patent Application WO/2010/093064
Kind Code:
A1
Abstract:
Disclosed is a fire-resistant phosphorus-containing epoxy resin composition which includes a phosphorus-containing epoxy resin (X) and a curing agent (Y). The aforementioned phosphorus-containing epoxy resin (X) is obtained via a reaction between an epoxy resin (a) containing 80 to 100 weight % of a bifunctional epoxy resin with a naphthalene skeleton, and a phosphorus compound (b) mixed with a ratio where for each mole of a chemical (1) there is 0.06 or fewer moles of another chemical (2). Said fire-resistant phosphorus-containing epoxy resin composition is characterized by having a phosphorus content greater than or equal to 0.5 weight % and less than 2.0 weight % of the entire epoxy resin composition, and consequently can be used as a resin composition in the production of copper-clad laminates having a fire-resistant effect, and a hardened substance using said composition has superior fire resistance, adherence, heat resistance, and moisture resistance.
