Problems solved by technology

In the process of process implementation, the red glue is cured and dried on the equipment that is in contact with the red glue, such as the dispensing needle, printing scraper or stencil, and it is difficult to clean.
[0003] In the industry, oil-soluble solvents such as acetone and alcohol are commonly used to clean cured red glue. A single solvent has poor cleaning effect and is prone to residues on equipment, and they are all flammable and irritating substances, which are harmful in the production environment. There are also cleaning agents mixed with acetone, ether, alcohol, toluene and other solvents. The cleaning effect is good, but it is easy to pollute the water body, and long-term contact will also be harmful to the human body.

Embodiment 1

[0019] The mass percent (%) of each component is: 10 propylene glycol butyl ether, 10 ethylene glycol butyl ester, 15 propylene glycol methyl ether acetate, 30 divalent ester, 5 diethanolamine, 10 isopropanol, 20 deionized water.

[0020] Preparation steps:

[0021] a. Accurately weigh each component in sequence according to the formula;

[0022] b. Add propylene glycol butyl ether, ethylene glycol butyl ester, propylene glycol methyl ether acetate, and dibasic acid ester to the reaction kettle in order to stir and mix, and continue to stir for 5 minutes until the mixture is fully mixed;

[0023] c. Add diethanolamine, isopropanol, and deionized water to the reaction kettle in turn, and continue stirring for 5 minutes until the mixture is uniform;

[0024] d. The solution obtained in step c was left to stand at room temperature for 1 hour to eliminate the air bubbles, and the red glue water-based cleaning agent was obtained.

Abstract

The invention discloses a red gum water-based cleaning agent including, by mass, 10-20% of propylene glycol ether, 10-20% of ethylene glycol ether, 10-20% of acetate, 10-30% of dibasic acid ester, 5-10% of ethanol amine, 10-20% of isopropanol, and 5-25% of deionized water. During use for removing red gum, the product can rapidly and effectively dissolve the components of cured red gum; and under the cooperative effect of the components in the cleaning agent, the cleaning agent is high in oil removal speed and has good cleaning effect, wherein residues are easy to wash away after the cleaning.The cleaning agent is stable and safe in use performance and cleaning waste liquid is easy to treat, so that the product is safe, environment-friendly and stable.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals, and in particular relates to a red glue water-based cleaning agent. Background technique [0002] Red glue is commonly used in the SMT welding process. The SMT red glue process uses the characteristics of red glue to be cured by heat. It is filled in the middle of the two pads through a printing machine or a glue dispenser, and then the curing is completed by patching and reflow soldering. , Finally, the surface mount side passes the wave crest during wave soldering, and the soldering process is completed without jigs. During the implementation of the process, the red glue is solidified and dried on the equipment that is in contact with the red glue, such as the dispensing needle, printing scraper or stencil, and it is difficult to clean. [0003] In the industry, oil-soluble solvents such as acetone and alcohol are commonly used to clean cured red glue. A single solvent has poor cleaning...
