Abstract

The invention discloses a parylene structure-containing phthalonitrile monomer, a phthalonitrile resin and a preparation method thereof. The parylene structure-containing phthalonitrile monomer is a parylene structure-containing phenol. The compound, nitrophthalonitrile is used as raw material, and it is obtained by reaction under the action of basic catalyst. The phthalonitrile monomer containing parylene structure is subjected to step heating and curing reaction to obtain parylene-containing phthalonitrile resin. In the present invention, the parylene structure is introduced into the phthalonitrile structure for the first time, and the prepared phthalonitrile monomer containing the parylene structure has a lower melting point, has an autocatalytic effect, and can be used as a traditional phthalonitrile monomer. The solidified curing agent is also a derivative monomer of parylene structure, which can be formed by thermal processing, which greatly reduces the processing difficulty and processing cost.

Description

technical field

[0001] The invention belongs to the technical field of phthalonitrile resin, and relates to a phthalonitrile monomer, a phthalonitrile resin and a preparation method thereof. Background technique

[0002] As a high-performance thermosetting resin, phthalonitrile resin was first developed by the US Navy Experimental Base. It has excellent thermal stability, thermomechanical properties, high glass transition temperature, low water absorption and excellent flame retardant properties. These properties make phthalonitrile resins have broad application prospects in composite materials, aerospace, marine vessels, electronic packaging and other fields.

[0003] Studies have shown that pure phthalonitrile monomer is difficult to cross-link and solidify to form phthalonitrile resin due to its rigid molecular structure and low reactivity and other factors at a high temperature of 280 ° C for nearly 100 hours. Limit the processing and application of phthalonitrile resin...
