Abstract

The invention discloses a flame-retardant bismaleimide resin and a preparation method thereof, and belongs to the field of polymer composite materials. The flame-retardant bismaleimide resin comprises the following raw materials by weight: 50 to 60 parts of a bismaleimide resin, 40 to 50 parts of an allylic compound, 1 to 10 parts of a flame retardant, and 0.5 to 1.5 parts of carbon nano-tubes. The bismaleimide resin prepared according to the preparation method is excellent in flame retardant property, so that the problem of low flame-retardant grade of the conventional bismaleimide resin is greatly solved; moreover, the flame-retardant bismaleimide resin is outstanding in heat resistance and excellent in mechanical property, so as to serve as a high-performance resin matrix, an adhesive, an insulating paint and the like in the high-tech fields such as the aerospace field, the electronic apparatus field, and the transportation and communication field, and be wide in application range. The preparation method is simple to operate, environmental-friendly and high in feasibility.

Description

technical field

[0001] The invention relates to a flame retardant resin composition and a preparation method thereof, in which it relates to a bismaleimide resin composition containing aminated carbon nanotubes and a flame retardant DOPO and a preparation method thereof, belonging to polymer composite field of materials technology. Background technique

[0002] Bismaleimide (BMI) is a reactive polyimide. Compared with other thermosetting resins, it has excellent high temperature resistance, mechanical properties, chemical resistance, and radiation resistance. It has been widely used In aerospace, aviation, machinery, electronics and other materials. Nowadays, the requirements of some cutting-edge fields are becoming more and more stringent, and there are higher requirements for the flame retardancy of resins. Although compared with thermosetting resins such as epoxy, the flame retardancy of bismaleimide resins reaches a certain level. However, it still cannot meet the flam...
