Abstract

The epoxy resin bromide is made up (A). phenol-benzaldehyde multifunctional epoxy resin 10-70 wt%, (B). bifunctinoal epoxy resin 0-55 wt%, (C). bromine-containing bifunctinoal epoxy resin 0-20 wt% and (D). tetrabromobisphenol A 15-40 wt% as main component through the process of synthesis. Said invented epoxy resin bromide can be used for making glass fibre laminated plate with high glass transfer temp. (Tg) and excellent heat resistance, and can be used to make high-performance electronic material.

Description

technical field [0001] The present invention relates to a novel brominated epoxy resin with suitable reactivity and a wide lamination processing range in the glass fiber laminated board manufacturing process, which has good processing operability and the obtained laminated substrate has a high glass transition temperature (Tg) and excellent heat resistance, suitable for high-performance electronic materials. Background technique [0002] With the development of printed circuit boards becoming lighter, thinner, smaller and more complex, the demand for high-performance materials is becoming more and more urgent. Usually the Tg value of a material is a very useful indicator, indicating the ability of the material to withstand dynamic stress such as vibration, high temperature, etc. at an operating temperature. If the material temperature is higher than Tg, it will often lead to poor interlayer bonding, and it will be bonded to copper foil. Then the strength is lost, resulting ...
