Abstract

The invention provides a protective film removal chemical liquid for an LED aluminum surface. The film removal chemical liquid comprises the following components in parts by weight: 10-15 parts of hydrogen peroxide, 10-15 parts of sodium hydroxide, 5-10 parts of potassium hydroxide, 5-10 parts of lauryl sodium sulfate, 5-10 parts of ammonium molybdate, 5-10 parts of sodium molybdate, 1-5 parts ofcorrosion inhibitor, 1-5 parts of accelerant, 1-5 parts of oxidant, 1-5 parts of corrosion inhibitor and 70-80 parts of water. The film removal chemical liquid is a film removal chemical liquid developed with regard to film removal for the LED aluminum surface, does not attack the aluminum surface, keeps the glossiness of the original metal aluminum surface, and is simple to operate, easy to clean, and residual-free; and during use, an aluminum substrate do not cover a protection film, and meanwhile, the aluminum surface cannot be corroded.

Description

technical field [0001] The invention relates to a film-removing potion for protecting the aluminum surface of LEDs. Background technique [0002] Aluminum substrate is a metal-based copper-clad laminate with good heat dissipation function. Generally, a single-sided panel consists of a three-layer structure, which is a circuit layer (copper foil), an insulating layer and a metal base layer. Commonly found in LED lighting products. There are two sides, the white side is for soldering the LED pins, and the other side shows the natural color of aluminum, which is usually coated with heat-conducting gel and then in contact with the heat-conducting part. There are also ceramic substrates and so on. [0003] Aluminum substrate is a metal-based copper-clad laminate with good heat dissipation function. Generally, a single-sided panel consists of a three-layer structure, which is a circuit layer (copper foil), an insulating layer and a metal base layer. For high-end use, it is also...
