LED substrate dewaxing cleaning agent

Abstract

The invention discloses an LED substrate dewaxing cleaning agent. The LED substrate dewaxing cleaning agent comprises a dispersing agent, isomeric alcohol ether carboxylate, triethanolamine oleate, an organic solvent, 1H-benzotriazole, isopropylate triphenyl phosphate, 2-methyl-4-isothiazolin-3-one, isomeric alcohol ethoxylates, enol ether, a penetrant and ethyl acetate. The LED substrate dewaxing cleaning agent can be applied to various LED substrates, is high in cleaning efficiency, dewaxing capability and safety, free from environmental pollution, energy saving, low in washing cost and free from damage to the substrates during washing.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a cleaning agent for removing wax from an LED substrate. Background technique [0002] With the development of the diameter of the LED substrate substrate to a large size, the wax polishing method has become a mainstream technology for polishing the LED substrate substrate, so it is necessary to introduce the wax removal technology of the LED substrate substrate. Some commonly used technologies in the dewaxing process of LED substrates. In the past, the usual method of dewaxing was to use halogenated hydrocarbon solvents, including organic solvents such as trichloroethylene, dichloromethane, tetrachloroethylene, and trichlorotrifluoroethane. solution for cleaning. Halogenated hydrocarbon solvents are liquids that are denser than water and hardly soluble in water. He is nonflammable or flame retardant. Halogenated hydrocarbon solvents have good cleaning effect and low cost, but because of th...

[0003] Chinese patent CN101974377A discloses a cleaning agent for removing wax from LED gallium arsenide substrate substrates. The cleaning agent includes the following components: organic solvents, organic bases, surfactants, inorganic salts and the remainder of deionized water, wherein, Said organic solvent is alkane, cycloalkane or aromatic hydrocarbon solvent; said organic base is polyhydric polyamine, amine base, hydroxylamine or alcohol amine, and said surfactant is fatty alcohol polyoxyethylene ether, polyol One or more of esters, polymers, and elemental organic compounds. The inorganic salt is an alkaline salt. The cleaning agent can replace halogenated hydrocarbon solvents, which can achieve the cleaning effect of halogenated hydrocarbon solvents and the wax removal effect. Obviously, it has no effect on the gallium arsenide substrate, but the cleaning agent is only effective in removing wax when the LED substrate is a gallium arsenide substrate, and the effect of removing wax on other substrates such as silicon substrates is not very good it is good
