Abstract

The invention discloses an environment-friendly copper clad laminate (CCL) for an LED (Light-Emitting Diode) monochrome display, a glue solution and a preparation method. The glue solution for a CCL comprises the following raw materials by mass: 400-500 parts of resin, 8-12 parts of curing agent, 0.2-0.3 part of curing accelerator, 100-120 parts of solvent, and an inorganic filler that includes one or more of talc powder, kaolin, magnesium hydroxide, aluminum hydroxide, zinc borate, zinc molybdate, magnesium oxide, calcium carbonate, calcium silicate, barium sulfate and boron nitride, wherein the inorganic filler accounts for 10%-70% of the total mass of the raw materials. According to the invention, the CCL is good in heat resistance, high in heat dissipation performance, low in organic content, environment-friendly during waste treatment, low in production cost, and suitable for industrial production.

Description

technical field [0001] The invention relates to a copper-clad laminate for an environment-friendly LED monochrome display screen, a glue solution and a preparation method. Background technique [0002] Light-emitting diode (LED) is a semiconductor device that can directly convert electrical energy into light energy. It is characterized by energy saving, environmental protection, and long service life. The current LED manufacturing technology is developing towards high power and high brightness. The current capacity of high-brightness LED products has been increased, and the current has been developed from about 20mA in the early stage to the current 1A. High-power LED products have developed from 1W in the early stage to about 3W and 5W at present. These changes have greatly increased the heat per unit area. Generally speaking, only 15% to 20% of the input current of a high-power LED is converted into light, and the remaining 80% to 85% is converted into heat, that is, he...
