Formula and production process of epoxy resin adhesive as well as application of epoxy resin adhesive in copper-clad plate for light-emitting diode (LED)

Abstract

The invention discloses a formula and a production process of epoxy resin adhesive as well as application of the epoxy resin adhesive in a copper-clad plate for a light-emitting diode (LED), aiming atsolving the problems that the insulation performance of the copper-clad plate affects the quality of an LED screen, so thatand the LED screen is easily damaged if the insulation performance of the copper-clad plate is poor. The epoxy resin adhesive is characterized by being prepared from the following materials in parts by weight: 260-275 parts of epoxy resin, 2-3 parts of a curing agent, 25-35 parts of a solvent, 45-55 parts of magnesium hydroxide, 100-115 parts of silica powder, 0.1-1.5 parts of a coupling agent and 0.05-0.20 part of a curing agent accelerator, wherein the coupling agent isprepared from a silane coupling agent,sothat and;after the epoxy resin adhesive is used, the aim of enabling the insulation performance of the copper-clad plate to be better is achieved.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, more specifically, it relates to the formulation, production process and application of epoxy resin glue on copper-clad laminates for LEDs. Background technique [0002] Copper-clad laminate is a product made of wood pulp paper or glass fiber cloth as a reinforcing material, dipped in resin glue, covered with copper foil on one or both sides, and hot-pressed. The LED display is a flat panel display, which is composed of multiple small LED module panels, and is used to display various information such as text, images, videos, and video signals. [0003] At present, the Chinese patent with the publication number CN105128454A discloses a double-sided aluminum-based copper-clad laminate for LED lamps and its preparation method. layer, the first copper foil layer arranged on the first insulating layer and away from the aluminum base layer, the second copper foil layer arranged on ...

Problems solved by technology

[0004] This double-sided aluminum-based copper-clad laminate sets the vias for the electrical connection of the upper and lower layers of the circuit on the circumferential side of the copper-clad laminate and exposes them to facilitate the preparation of via holes. However, when this double-sided aluminum-based copper-clad laminate is used for For LED display screens, because LED displays are mostly used in computers, televisions and other equipment, most of these devices have small internal space, and LED lights are directly welded on the copper clad laminate, and the insulation performance of the copper clad laminate affects the quality of the LED display. The quality of the display screen, the poor insulation performance of the copper clad laminate can easily lead to damage to the LED display screen
