Abstract

The present invention discloses a halogen-free resin composition and a method for manufacturing a prepreg and a laminated board by using the halogen-free resin composition. The halogen-free resin composition is prepared by dispersing the following components in an organic solvent, wherein the components comprise, by weight, 10-100 parts of a halogen-free epoxy resin, 10-80 parts of cyanate, 10-70 parts of an anhydride curing agent, 10-100 parts of a benzoxazine resin, 0.01-1.0 part of a curing accelerator, 1-15 parts of a toughening agent, 0-50 parts of a fire retardation agent, and 0-100 parts of an inorganic filler, and the solid content of the halogen-free resin composition is 30-70 wt%. The prepared prepreg and the copper foil-clad laminated board have characteristics of good heat resistance, high glass-transition temperature, low water absorption rate, excellent fire retardation, low dielectric constant and low dielectric loss factor.

Description

technical field [0001] The invention belongs to the field of polymer composite material manufacturing, and in particular relates to a halogen-free resin composition and a method for manufacturing a prepreg and a printed circuit laminate using the halogen-free resin composition. Background technique [0002] In recent years, with the rapid development of cloud computing and mobile Internet, the transmission capacity of signals is getting larger and faster, and the transmission speed is getting faster and faster, and the signal processing frequency is developing towards high frequency. The dielectric constant (Dk) and dielectric loss factor (Df) of the circuit substrate have a great influence on the signal transmission of the end product. High Dk will slow down the signal transmission rate, and high Df will convert part of the electromagnetic energy of the signal into heat energy. The loss is in the substrate material and has a greater impact on the transmission of high-freque...
