Abstract

The invention discloses modified cyanate ester resin and a preparation method of the modified cyanate ester resin. The preparation method of the modified cyanate ester resin comprises the steps that by mass, 100 parts of molten cyanate ester resin and 0.503-4.167 parts of oxidized graphene-manganese-based metal organic framework hybrid body are evenly mixed, and the modified cyanate ester resin is obtained after curing. The oxidized graphene-manganese-based metal organic framework hybrid body is a hybrid material which is composed of oxidized graphene and a manganese-based metal organic framework, and the manganese-based metal organic framework is composed of manganous ions and an organic ligand through coordination bond. Compared with cyanate ester resin, the modified cyanate ester resin prepared with the method is lower in dielectric constant, lower in dielectric loss and better in fire resistance. The preparation method of the modified cyanate ester resin has the advantages that the technique is simple, cost is low, and the range of sources of raw materials is wide.

Description

technical field [0001] The invention relates to a thermosetting resin and a preparation method thereof, in particular to a modified cyanate resin and a preparation method thereof. Background technique [0002] With the development of integrated circuits, the size of large-scale integrated circuits is getting smaller and smaller. In order to meet their requirements, the development of high-performance insulating resins with good processability, good flame retardancy, and low dielectric constant has become the key. Cyanate ester (CE) resin, as a representative of high-performance thermosetting resin, has excellent thermal and mechanical properties, while low dielectric constant and stable dielectric loss in a wide frequency range. Based on these advantages, CE resins show great application prospects in the field of large-scale integrated circuits. However, like general heat-resistant thermosetting resins, CE resins also have the problem of high curing temperature (generally e...
