Abstract

The invention provides a preparation method of a coated filler slurry composition, a prepreg comprising the slurry composition, a laminated board and a printed circuit board. The preparation method comprises the following steps: mixing master batch filler with an organic solvent and a dispersant, mechanically stirring and uniformly dispersing the mixture, and further dispersing the mixed liquid through dispersing equipment to prepare prefabricated slurry; adding a catalyst into the prefabricated slurry, uniformly mixing the mixture, and marking the mixture as a liquid A; dissolving a coating agent in an organic solvent to prepare a solution, and marking the solution as a liquid B; adding the liquid B into the liquid A while stirring, and performing a reaction to obtain a reaction mixed solution; and storing the reaction mixed solution at normal temperature for 1-30 days to obtain the coated filler slurry composition. The coated filler slurry composition prepared by the invention can improve the dispersibility and flowability of the integral slurry composition and improve the resin flowability in a high filler filling state. The copper coated laminated board manufactured by the slurry composition has relatively good heat resistance and low coefficient of thermal expansion and good comprehensive performance.

Description

technical field [0001] The invention belongs to the technical field of pressing boards, and relates to a preparation method of a coated filler slurry composition, a prepreg containing the slurry composition, a laminate and a printed circuit board. 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 d...
