Abstract

The invention discloses a fluorine-containing low-dielectric-loss bismaleimide resin and a cured resin thereof, and a preparation method and application thereof. The resin is prepared by carrying out blend reaction on the following composition, wherein the composition comprises the following components in parts by weight: 20-120 parts of bismaleimide monomer, 20-120 parts of allyl compound, 20-120 parts of cyanate, 2-20 parts of thermoplastic high molecule and 0.1-1.5 parts of bismaleimide accelerator. At least one of the bismaleimide monomer and allyl compound contains fluorine. The bismaleimide resin disclosed by the invention has excellent heat stability, dielectric properties and mechanical properties, can be used as a high-performance composite material resin matrix, and has application value in the fields of copper clad plates, electronic packaging, aerospace and the like.

Description

technical field [0001] The invention belongs to the technical field of thermosetting resin and its preparation, and in particular relates to a fluorine-containing bismaleimide resin with low dielectric loss and its preparation and application. Background technique [0002] Bismaleimide resin (referred to as "bismaleimide resin") not only has outstanding heat resistance, heat and humidity resistance, mechanical properties and chemical resistance, but also has excellent dielectric properties (dielectric constant is 3.0-3.2, the dielectric loss is about 0.01-0.02). However, with the current development of electronic and electrical products in the direction of high frequency, high power and miniaturization, the properties of materials used in the fields of components, IC chips and PCB substrates have also proposed lower dielectric constants and lower dielectric constants. Electrical losses, higher glass transition temperature requirements. [0003] At present, there are four m...
