| titleOfInvention | Halogen-free flame-retardant epoxy resin precursor, molding compound product, preparation method and application thereof |
| abstract | The invention discloses a halogen-free flame-retardant epoxy resin precursor, a molding compound product, and preparation methods and applications thereof. The halogen-free flame-retardant epoxy resin precursor has a structure shown in the following formula: wherein R is 1 And R 3 Are all selected from substituted or unsubstituted alkyl (such as methyl, ethyl, isopropyl, etc.) or alkoxy (such as methoxy, ethoxy, etc.), R 2 Is phosphite ester substituent, n is more than or equal to 1 and less than or equal to 25. The preparation method comprises the following steps: at least enabling hydroxybenzaldehyde monomer, phenol monomer and phosphite ester monomer to carry out condensation reaction under the action of catalyst to obtain bisphenol monomer, and then at least enabling the bisphenol monomer to react with epoxy alkyl halide and strong base under the action of phase transfer catalyst. The halogen-free flame-retardant epoxy resin precursor can be directly cured with a curing agent to obtain thermosetting epoxy resin with excellent thermal property, mechanical property and flame retardant property, and can also be used as a reactive flame retardant for modifying epoxy resin. |
