Abstract
The present application discloses an allyl-type flame-retardant prepolymer, a resin composition, a composite resin, a prepreg, and a laminate. The allyl-type flame-retardant prepolymer provided in the present application is prepared by pre-polymerization of an allyl-type benzoxazine compound and an allyl-type phosphorous compound in a mass part ratio of 100:(20 to 80).
Claims16
An allyl-type flame-retardant prepolymer, comprising 100 mass parts of an allyl-type benzoxazine compound and 20 to 80 mass parts of an allyl-type phosphorous compound;
- wherein the allyl-type phosphorous compound has the following structural formula:
- the allyl-type benzoxazine compound is selected from the compounds of the following structural formulas and combinations thereof:
- wherein X is independently selected from —CHR1—, —CR2R3—, —SO2—, or —O—;
- R1, R2, and R3 are each independently selected from —H or —CH3.
A resin composition, comprising 10 to 30 mass parts of the allyl-type flame-retardant prepolymer of claim 1, 50 to 100 mass parts of a bismaleimide resin, 30 to 80 mass parts of a cyanate resin, 5 to 30 mass parts of an additional functional resin, and 10 to 60 mass parts of an inorganic filler.
A composite resin, comprising a resin composition comprising 10 to 30 mass parts of the allyl-type flame-retardant prepolymer of claim 1, 50 to 100 mass parts of a bismaleimide resin, 30 to 80 mass parts of a cyanate resin, 5 to 30 mass parts of an additional functional resin, and 10 to 60 mass parts of an inorganic filler.
A prepreg, comprising a reinforcing material and a resin material loaded on the reinforcing material, wherein the resin material comprising a resin composition comprising 10 to 30 mass parts of the allyl-type flame-retardant prepolymer of claim 1, 50 to 100 mass parts of a bismaleimide resin, 30 to 80 mass parts of a cyanate resin, 5 to 30 mass parts of an additional functional resin, and 10 to 60 mass parts of an inorganic filler.
A laminate, prepared from a prepreg, wherein the prepreg comprising a reinforcing material and a resin material loaded on the reinforcing material, wherein the resin material comprising a resin composition comprising 10 to 30 mass parts of the allyl-type flame-retardant prepolymer of claim 1, 50 to 100 mass parts of a bismaleimide resin, 30 to 80 mass parts of a cyanate resin, 5 to 30 mass parts of an additional functional resin, and 10 to 60 mass parts of an inorganic filler.
