Abstract

The invention discloses a bismaleimide resin prepolymer and its application. The specific preparation is as follows: 2-allylphenyl glycidyl ether and terephthalic acid are blended in acetonitrile, and an esterification reaction occurs under the condition of a quaternary ammonium salt as a catalyst to obtain bis(3- (2‑allylphenoxy)‑2‑hydroxypropyl)terephthalate; bis(3‑(2‑allylphenoxy)‑2‑hydroxypropyl)terephthalate The formate ester and the bismaleimide are uniformly mixed to obtain a bismaleimide resin prepolymer, which is cured to obtain a remodelable bismaleimide resin. The remodelable bismaleimide resin prepared by the bismaleimide resin prepolymer of the present invention not only has excellent heat resistance and mechanical properties, but also can realize remodeling under hot pressing conditions, and is used in aerospace, It has broad application prospects in industrial fields such as transportation, electronic information, new energy, and electrical insulation.

Description

technical field

[0001] The invention relates to a thermosetting resin and a preparation method thereof, in particular to a remodelable bismaleimide resin prepolymer and its preparation method and application, belonging to the technical field of polymer materials. Background technique

[0002] Thermosetting resin is an important class of polymer materials, accounting for about 18% of the total polymer. Thermosetting resins are widely used in many fields such as electronic information, energy, aerospace, transportation, etc. as composite material matrix, coating, adhesive, etc. With the increasingly serious problem of environmental pollution and the concept of green and sustainable development, the recycling and reuse of thermosetting materials after their effective service life has become an urgent problem to be solved. At the same time, with the rapid development of electronic technology, the life cycle of a large number of electronic products and smart devices has been sig...
