Abstract

The invention provides an epoxy resin glue solution comprising brominated bisphenol A resin, dicyandiamide, dimethylimidazole, inorganic filling materials, aniline and solvents, wherein, the inorganic filling materials comprise aluminium hydroxide. The invention also provides a preparation method for the epoxy resin glue solution, and an application of the epoxy resin glue solution for preparing a prepreg and a FR-4 copper-clad panel. The invention further provides the prepreg and FR-4 copper-clad panel prepared by using the epoxy resin glue solution, and a preparation method for the prepreg and FR-4 copper-clad panel. According to the invention, the defect of energy wasting caused by high light transmittance existing in the copper-clad panel in the prior art is overcome. The prepreg and FR-4 copper-clad panel prepared by using the epoxy resin glue solution disclosed in the invention can be used as a black substrate without affecting other performances of the substrate. The copper-clad panel can reduce the light transmittance and is suitable for using as an LED substrate.

Description

technical field [0001] The present invention relates to the field of copper-clad laminates, in particular to an epoxy resin glue and a preparation method thereof, and in particular to a prepreg and FR-4 copper-clad laminate prepared from the epoxy resin glue and their preparation methods. Background technique [0002] Due to the outstanding characteristics of low energy consumption and high efficiency of LED (light-emitting diode), LED has been widely used in electrical indication, LED display, LCD backlight, landscape lighting, interior decoration and other fields. The rapid development of LED has also promoted the development of functional copper-clad laminates. The reason why it is called functional copper-clad laminates is that the copper-clad laminates used for LEDs provide the required insulating substrates, conductive copper foils, and signals in addition to ordinary copper-clad laminates. In addition to transmission, the substrate also needs to have a good shading fu...
