Abstract

The invention discloses a dicyclopentadiene/epoxy resin compound and a preparation method thereof. The preparation method comprises the steps that dicyclopentadiene monomers, epoxy resin, an epoxy resin curing agent and a curing accelerator are evenly mixed, then an olefin polymerization catalyst is added, the epoxy resin and dicyclopentadiene are polymerized and cross-linked respectively, and thus a high-molecular polymer with an interpenetrating network structure is obtained. The dicyclopentadiene/epoxy resin compound has low dielectric constant and dielectric loss factor and good heat resistance, and can be widely applied to the manufacturing industry of high-frequency copper-clad plates.

Description

technical field [0001] The invention belongs to the technical field of electronic materials, and in particular relates to a dicyclopentadiene / epoxy resin compound and a preparation method thereof. Background technique [0002] As my country promotes the development of next-generation information technologies such as big data, the Internet of Things, AI, and 5G, and accelerates the construction of products and application systems such as software, hardware, and equipment services, the market's demand for high-end printed circuit boards (PCBs) will grow exponentially. As the core raw material copper clad laminate (CCL) in PCB production products, its market size is also increasing. At the same time, with the high-speed and multi-functionalization of product information processing and the increase in the amount of transmitted information, copper-clad laminates are required to have higher high-frequency characteristics, lower dielectric constant and dielectric loss factor, and b...
