| titleOfInvention | A kind of preparation method of phosphorus-containing epoxy resin |
| abstract | The invention discloses a preparation method of phosphorus-containing epoxy resin, which is characterized in that: 45-80 mass parts of 9,10-dihydro-9-oxa-10-phosphinephenanthrene-10-oxide, 30-50 Add the diallyl dihydroxy compound in parts by mass to the reactor, raise the temperature to 80°C-110°C under stirring for 2-5 hours, add 170-230 parts by mass of novolac epoxy resin, 75-105 parts by mass of bisphenol-type diglycidol Ether, 0.2-1 parts by mass of catalyst, react at 120-150°C for 2-5 hours, then raise the temperature to 160-190°C for 4-7 hours, and cool down to obtain phosphorus-containing epoxy resin; add 120-155 The parts by mass of the solvent are uniformly mixed to obtain a phosphorus-containing epoxy resin solution. The phosphorus-containing epoxy resin prepared by the invention is suitable for use as a matrix resin for electronic copper-clad laminates, and has good performance. |
