Abstract

The invention provides a silicon dioxide slurry composition as well as a preparation method and application thereof. The silicon dioxide slurry composition is prepared from silicon dioxide micro powder and an organic solvent, wherein the surface of the silicon dioxide micro powder is coated with nanoscale silicon dioxide; a raw material source of the nanoscale silicon dioxide is organosilicon; the nanoscale silicon dioxide accounts for 0.1 to 10 percent of total mass of the silicon dioxide micro powder. According to an epoxy laminated board produced by using the silicon dioxide slurry composition provided by the invention, the dispersity of filler can be well improved, and the mobility of boards is improved. In addition, the preparation method of the silicon dioxide slurry composition provided by the invention is simple, efficient and easy for industrial production.

Description

technical field [0001] The invention belongs to the technical field of pressing plates, and relates to a silica slurry composition and a preparation method and application thereof. Background technique [0002] With the development of information science and technology, integrated circuits are developing in the direction of high frequency, high speed, high density, high power, and multi-function. Therefore, the performance requirements for copper clad laminates are also getting higher and higher. In particular, the requirements for data transmission speed and transmission frequency are getting higher and higher, among which, the requirements for heat resistance and expansion rate of the board are particularly prominent. In order to improve the heat resistance of the board and reduce its expansion coefficient, the most effective method is to add as much filler as possible to the glue formula, such as silicon dioxide. However, when a large amount of fillers are used, especial...
