preparation example Construction

[0041] A preparation method of a complex environment water-based cleaning agent, comprising the following steps:

[0042] Measure the raw materials of each component according to the composition and content ratio of the water-based cleaning agent in the aforementioned complex environment, add deionized water into the reaction kettle with a stirrer and start stirring, heat the reaction kettle, and keep the temperature at 30 At ±5°C, add surfactant, corrosion inhibitor and defoamer respectively, keep stirring until completely mixed, then stop stirring.

[0043] A method for cleaning complex environments with water-based cleaning agents, comprising the steps of:

[0044] 1) Use a water bath to heat the liquid medicine in a closed container to 25°C~40°C;

[0045] 2) Soak the pieces to be washed in the liquid medicine in step 1) for 20min~35min, and then put the pieces to be washed into the ultrasonic cleaning machine after soaking. The cleaning time is 10min~25min, and the cleani...

Embodiment 1

[0049] The composition of the water-based cleaning agent for complex environments is as follows: Surfactant accounts for 5% by weight, of which non-ionic surfactant:anionic surfactant=3:7, corrosion inhibitor 0.01%, defoamer 0.1%, and the balance for deionized water.

Embodiment 2

[0051] The composition of the water-based cleaning agent for complex environments is as follows: Surfactant accounts for 6% by weight, of which nonionic surfactant:anionic surfactant=7:15, corrosion inhibitor 0.05%, defoamer 0.12%, and the balance for deionized water.

Abstract

The invention discloses a complex environment water-based cleaning agent, which is characterized in that it is made of the following raw materials in weight percentage: surfactant: 3%-12%; corrosion inhibitor: 0.01%-0.25%; defoamer: 0.1%~0.3%; the balance is deionized water, and the sum of the weight percentages of each component is 100%. The water-based cleaning agent obtained by the present invention can quickly and effectively remove flux residues and other pollutants on the surface of components, and has good compatibility and wide application range, especially suitable for complex environments such as high temperature, high acid, alkali and high oxidation In the cleaning process; low foam, low volatility, low toxicity, good cleaning effect, no residue on the surface after washing, and bright solder joints; the water-based cleaning agent is simple to prepare, and the cleaning process is easy to operate. It is used in conjunction with automatic spray cleaning and ultrasonic cleaning on the market.

Description

technical field [0001] The invention relates to the field of cleaning agent manufacturing after welding and assembly of circuits, in particular to a water-based cleaning agent and a cleaning method for complicated environments. Background technique [0002] In recent years, with the vigorous development of the domestic electronic information industry, the high density and high integration of packaging technology, and the emergence of three-dimensional packaging technology, Moore's Law was born, and the extremely small spacing difference makes the packaging requirements also change. be more stringent. A little flux residue and tiny particles and dust in the atmosphere may cause poor circuit contact, short circuit or even paralysis of the entire circuit, making small components unable to work normally, ranging from poor equipment operation to large industrial errors (such as Sensors, testers), or lead to other safety accidents. In order to avoid these situations and ensure t...
