Abstract

The invention discloses a bismaleimide resin prepolymer and an application thereof. 2-allylphenyl glycidyl ether is blended with terephthalic acid in acetonitrile, and an esterification reaction is carried out with a quaternary ammonium salt as a catalyst to obtain a bis(3-(2-allylphenoxy)-2-hydroxypropyl)terephthalate containing a reversible dynamic group; and the bis(3-(2-allylphenoxy)-2-hydroxypropyl)terephthalate is uniformly mixed with bismaleimide to obtain the bismaleimide resin prepolymer, and the bismaleimide resin prepolymer is cured to obtain a remoldable bismaleimide resin. The remoldable bismaleimide resin prepared by using the bismaleimide resin prepolymer has good heat resistance and good mechanical properties, also can be remolded under a hot pressing condition, and has broad application prospects in the fields of aerospace, transportation, electronic information, new energy and insulated electrics.

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...
