Problems solved by technology

[0004] Since the existing cleaning agents are composed of one or several low-boiling point organic solvents, they are suitable for cleaning by immersion. The solvents are volatile quickly, and a large amount of volatilization needs to be continuously replenished during the equipment cleaning process, and the wettability of the solvent Not good, it cannot be evenly distributed on the surface of corn cob particles, resulting in low cleaning efficiency. Therefore, the cleaning effect of existing cleaning agents in the grinding and cleaning of corn cob particles is not good

Embodiment 1

[0022] A new type of welding slag cleaning agent, select 40 parts of limonene, 30 parts of methanol, 30 parts of high-boiling range petroleum ether, do not add emulsifier and penetrating agent, then add limonene, methanol, and high-boiling range petroleum ether into the reaction vessel and mix well. .

Embodiment 2

[0024] A new type of welding slag cleaning agent, select 60 parts of limonene, 20 parts of ethanol, 20 parts of high-boiling range petroleum ether, do not add emulsifier and penetrating agent, then add limonene, methanol, and high-boiling range petroleum ether into the reaction vessel and mix well. .

Embodiment 3

[0026] A new type of welding slag cleaning agent, select 50 parts of limonene, 26 parts of isopropanol and ethanol 1:1 mixed solvent, 22 parts of high boiling range petroleum ether, 1 part of castor oil polyoxyethylene ether, and 1 part of penetrating agent. Wherein, the penetrating agent is a mixture of 1,4-cyclohexanediol dimethyl ether and N-benzylamine phenylenediamine, and the weight ratio of 1,4-cyclohexanediol dimethyl ether and N-benzylamine phenylenediamine is 1:1.

Abstract

The invention relates to the technical field of cleaning agents, in particular to a novel welding slag cleaning agent and a preparation method thereof. The novel welding slag cleaning agent comprisesthe following components in parts by weight: 40-60 parts of limonene, 20-30 parts of an alcohol solvent, 20-30 parts of a high-boiling range petroleum solvent, 0-1 part of an emulsifying agent and 0-1part of a penetrating agent. The cleaning agent uses the plant extract as a main solvent, so that the dissolving power is stronger than that of a common solvent, no environment forbidden substance isused, and the cleaning agent is green and environmentally friendly. By adjusting the proportion of the volatile components, the volatility of the cleaning agent is moderate, a large amount of volatilization in the cleaning process cannot be caused, and the requirement for rapid volatilization of a small amount of cleaning agent remaining on the surfaces of cleaned components can be satisfied.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a novel welding slag cleaning agent and a preparation method thereof. Background technique [0002] Flux is needed in the soldering process of electronic components, and flux is an important part of solder. After soldering, the residual flux on the substrate will adversely affect the performance of electronic components, so these substances need to be cleaned in the subsequent process. [0003] Chinese patent CN104450236A discloses a cleaning agent for soldering, the cleaning agent for soldering includes: the first cleaning agent and the second cleaning agent used in sequence, and the first cleaning agent consists of coconut acid diethanolamide, iso Propanol, sodium carbonate and deionized water are mixed, and the second cleaning agent is made by mixing denatured alcohol and gum rosin, and the parts by weight of the industrial alcohol in the second cleaning agent are 15-...
