Description

Epoxy resin composition, preparation method and application thereof, and aluminum-based copper-clad plate
Technical Field
The invention relates to an epoxy resin composition, a preparation method and application thereof, and an aluminum-based copper-clad plate.
Background
With the maturity of the LED manufacturing technology, the LED luminance is greatly improved, the lifetime is greatly improved, and the production cost is greatly reduced, so that the LED lighting is widely popularized and becomes a main lighting mode for replacing traditional light sources such as incandescent lamps. The photoelectric conversion efficiency of the high-power LED is low, and about 80% of input electric energy is converted into heat. Because the area of the LED chip is small, if the generated heat cannot be dissipated in time, the luminous efficiency is rapidly reduced, and the service life is also rapidly reduced. Thus, heat dissipation from high power LEDs is a problem that must be addressed.
The aluminum-based copper-clad plate is a composite material made of an aluminum plate, a heat-conducting insulating medium layer and a conductive copper foil and is used for manufacturing an aluminum-based printed circuit board. The LED lamp has excellent heat dissipation performance, electromagnetic shielding performance, machining performance and the like, and is widely applied to LED illumination, high-power electrical equipment, automobiles, power supply equipment and the like.
Therefore, the aluminum-based copper clad laminate is also generally used as a preferred material for heat dissipation of high-power LEDs. Two aluminum-based circuit boards for loading LED lamp beads and lamp bead driving are generally arranged in the existing LED lamp, the requirement on miniaturization of the lamp is higher and higher, and the installation mode of installing the LED lamp beads and the lamp bead driving on two sides of one aluminum-based circuit board is provided. The mounting mode has the greatest advantages that the miniaturization of the lamp is met, the service life of the lamp is not influenced, and the mounting mode is an ideal mounting mode. However, the double-sided mounting can cause the heat dissipation of the aluminum-based copper-clad plate to be poor, which affects the service life of the LED, while the conventional aluminum-based copper-clad plate is generally only suitable for single-sided mounting, and has poor heat resistance, which is difficult to meet the requirement of the double-sided mounting mode of the LED on the heat-conducting property.
Therefore, how to prepare the aluminum-based copper-clad plate with excellent heat conductivity, electrical insulation performance and heat resistance is a technical problem to be solved urgently in the field.
