| titleOfInvention | Flame-retardant resin prepolymer, and thermosetting resin composition, prepreg and laminated board prepared from same |
| abstract | The invention discloses a flame-retardant resin prepolymer which is prepared by at least pre-polymerizing bismaleimide resin and allyl compounds. Compared with the prior art, the allyl compound containing the DOPO or DPPO structure is used as the bismaleimide resin modifier, and on the basis of not affecting the performance of the bismaleimide resin, the phosphorus-containing group is well introduced into the cross-linked network structure of the bismaleimide resin, so that the nitrogen element and the phosphorus element in one cross-linked network structure are cooperatively flame-retardant, the flame retardance of the cured product can be reduced to reach the phosphorus content required by UL94V-0, other flame retardants are not required to be added, and the cured product with excellent halogen-free flame retardance, high heat resistance, high adhesion, toughness and thermal expansion coefficient is obtained. |
