Abstract
The invention belongs to the technical field of surfactants, and particularly relates to a chemical preparation used in the field of LEDs (light-emitting diode), which is a composition used for cleaning LED chip solid wax. Comprises 15 to 20 percent of rosinyl imidazoline nonionic surfactant, 2.5 to 3 percent of penetrating agent, 8 to 10 percent of emulsifying agent, 1.5 to 2 percent of chelating agent, 8 to 10 percent of organic auxiliary agent and the balance of high-purity water. The rosin-based imidazoline non-ionic surfactant, the penetrating agent and the emulsifying agent are mixed, so that the solid wax can be quickly emulsified and dissolved, the metal electrode material is protected, the problem of corrosion of water-based products on the market on the metal electrode is solved, and the rosin-based imidazoline non-ionic surfactant, the penetrating agent and the emulsifying agent are easy to clean and have no residue.
Description
Technical Field
The invention belongs to the technical field of surfactants, and particularly relates to a chemical preparation composition used in the field of LEDs, which is used for cleaning LED chip solid wax.
Background
Before the LED chip packaging test, one surface of the functional area needs to be coated with solid wax, and the functional area is fixed on a grinding disc under the pressure, so that the exposed surface of the chip is ground and polished. And after grinding and polishing, cleaning by using a solid wax cleaning agent to recover the intrinsic functional surface of the chip. The solid wax used in the industry at present contains long-chain fatty acids, rosin and modified rosin derivatives as main components.
The water-based wax removing liquid adopted by the solid wax cleaning agent on the market has low dissolution rate to the solid wax, corrodes the electrode on the surface of the chip, and can achieve the purpose of thoroughly cleaning dirt only by cleaning the subsequent chemical acetone, so that the problems of complex cleaning process, low wax dissolving efficiency, corrosion to the electrode, need of extra solvent acetone cleaning, increased use cost and the like exist. Patent CN 105779151A discloses a dewaxing cleaning solution and a preparation method and application thereof, which adopts a high-efficiency nonionic surfactant, a low-foam-inhibiting surfactant, a dispersion stabilizer and a deionized water system to clean solid wax. The water-based solid wax cleaning agent has the problems of complex cleaning process, low wax dissolving efficiency, electrode corrosion, additional solvent acetone cleaning, increased use cost and the like.
