Document Type and Number:
WIPO Patent Application WO/2023/125784
Kind Code:
A1
Abstract:
The present invention relates to a resin composition, and a prepreg and the use thereof. The resin composition comprises the following components, in parts by weight: 50 to 150 parts of a modified epoxy resin, 40 to 120 parts of a modified benzoxazine resin, 20 to 100 parts of a bismaleimide resin, 0.1 to 15 parts of an initiator, and 150 to 550 parts of an inorganic filler, wherein the structural formula of the modified epoxy resin is (1-1), and the modified benzoxazine resin is a modified basic benzoxazine resin having a double-bond structure as a terminal group. In the resin composition, a polybutadiene modified epoxy resin and the bismaleimide resin can form an interpenetrating polymer network; ultimately, a resin composition with a low dielectric constant, low dielectric loss and a low linear expansion coefficient is obtained.
