The invention discloses a phosphorus-containing flame-retardant BMI resin composition which is characterized by comprising the following components in parts by weight: 10-50 parts of phosphorus-containing maleimide resin; 20-60 parts of polyphenyl ether resin and 10-30 parts of cyanate ester resin, wherein the chemical structural formula of the phosphorus-containing maleimide resin is shown as a formula 1. The invention also discloses the application of the composition. The phosphorus hybrid flame-retardant structure is combined with the maleimide group to prepare the phosphorus flame-retardant maleimide resin, so that the preparation of the resin composition can be carried out, the inherent problems of flame retardance, heat resistance and the like of the resin can be solved, and meanwhile, the terminal of the flame retardant contains a functional maleimide active group, and the flame retardant can react with other resins as a reactive flame retardant, so that the compatibility of the flame retardant and the material is improved, and the thermal property, the mechanical property, the dielectric property and the like of the material are improved. |
