High-efficient detergent for electronic product

Abstract

The invention discloses a high-efficient detergent for an electronic product. The high-efficient detergent is prepared from the following raw materials in parts by weight: 65 to 75 parts of fluorine-containing ampholytic surfactant, 10 to 15 parts of cosolvent, 1 to 3 parts of defoaming agent, and 10 to 15 parts of deionized water. A preparation method of the ampholytic surfactant comprises the following steps: (1) dissolving N-tri(hydroxymethyl)methyl-2-amino ethanesulfonic acid in a solvent, adding long-chained haloalkane, stirring and reacting for 6 to 8 hours at 40 to 50 DEG C, performingthe rotary evaporation, cleaning for 5 to 7 times by using diethyl ether, and then performing the rotary evaporation again to obtain an intermediate product; and (2) dissolving the intermediate product prepared in the step (1) in the deionized water, then adding sodium hydroxide and tetrabutylammonium bromide, stirring for 0.5 to 1.5 hours at the room temperature, adding fluorine-containing long-chained halohydrocarbon, refluxing, stirring and reacting for 15 to 20 hours at 70 to 85 DEG C, after the reaction is ended, cooling, extracting by using dichloromethane, washing for 3 to 5 times by using water, drying organic layer anhydrous magnesium sulfate over night, and performing the rotary evaporation to remove the solvent. The high-efficient detergent for the electronic product has highercleaning capacity and a higher cleaning effect, achieves lower cost and environment-friendlomess, and has the antibacterial performance.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a high-efficiency cleaning agent for electronic products. Background technique [0002] With the advancement of science and the development of society, electronic products have entered thousands of households and are closely related to people's lives. In the process of production, processing and preparation of electronic products, due to the precision and technical requirements of electronic products, the products need to be processed and cleaned. The surface cleanliness of electronic materials directly affects the physical and electrical properties of electronic materials, which in turn affects the normal use of electronic products. The electronic materials used to make electronic products have potential pollution in every production process, which may lead to defects and device failures. If the cleaning effect is not good, it will cause short circuits or even fires, whi...

AI Technical Summary

Problems solved by technology

The electronic materials used to make electronic products have potential pollution in every production process, which may lead to defects and device failures. If the cleaning effect is not good, it will cause short circuits or even fires, which will directly affect the yield of devices. , performance and reliability

[0003] The cleaning effect of electronic products is determined by the cleaning agents used. The cleaning agents used in the traditional electronics industry contain a large number of substances that destroy the ozone layer, such as trifluorotrichloroethane and 1,1,1-trichloroethane, It will cause pollution to the environment and has been gradually eliminated. The existing cleaning agents for electronic products have high production costs and the cleaning ability needs to be further improved. After cleaning, they will have a certain corrosive effect on materials and contain sodium silicate and sodium carbonate salt pollution. Environmental substances will cause certain pollution to the environment and are relatively unsafe to use
