Abstract

The invention discloses a flame-retardant maleimide composition and a preparation method thereof for a copper-clad laminate. The flame-retardant maleimide composition consists of 25-37 parts by mass of epoxy resin, 63-75 parts by mass of flame-retardant It is composed of imide resin, 45-70 parts by mass of cyanate resin, 45-80 parts by mass of filler, and 0.2-0.7 parts by mass of accelerator. The preparation method of flame-retardant maleimide copper-clad laminate is: prepare flame-retardant maleimide resin, prepare flame-retardant maleimide prepreg, laminate 3-20 layers of prepreg, attach copper foil on both sides , placed in a hot press at 150-170°C, pressurized to 0.2-4MPa, pressed for 0.5-1h, then heated to 190-250°C for 3-5h, then cooled and depressurized to obtain the resistance Burned maleimide copper clad laminate. By adopting the invention, the flame-retardant maleimide copper clad laminate has good dielectric performance and heat resistance performance, and can be widely used in the field of printed circuit boards.

Description

technical field [0001] The invention belongs to flame-retardant maleimide synthetic resin and processing, in particular to a flame-retardant maleimide composition and a preparation method of a copper-clad laminate. The flame-retardant maleimide composition of the invention is suitable for high The preparation of frequency copper clad laminates can be widely used in the field of printed circuit boards. Background technique [0002] The high-frequency and high-speed development of 5G communication technology has put forward higher requirements for the comprehensive performance of CCL, which not only requires CCL to have low dielectric constant and dielectric loss, but also good heat resistance and flame retardant properties. and low moisture absorption. At present, many countries such as Europe, America, Japan and South Korea gradually prohibit the use of halogen-containing flame retardants in electronic equipment, and require that electronic copper clad laminates should not ...
