Problems solved by technology

[0002] During the implementation of the SMT welding process, red glue is often used to print or dispense glue on the copper clad laminate. On the equipment that is in contact with the red glue, such as the dispensing needle, the printing scraper or the stencil, the red glue that adheres to the surface is in the welding process. Cured and dried, difficult to clean
At present, under the current society's requirements for industrial production to reduce pollution, halogen-free cleaning agents are generally used as cleaning agents, such as acetone, alcohol and other oil-soluble solvents to clean equipment with cured red glue, but the cleaning effect of a single solvent Poor, easy to have residues on the equipment, and they are all flammable and irritating substances, which are harmful in the production environment. There are also cleaning methods that are mixed with acetone, ether, alcohol, toluene, etc. The cleaning effect is good, but it also has a relatively volatile nature. The cleaning waste liquid has certain pollution to the environment and is harmful to the workers.

Abstract

The invention discloses an environmentally-friendly red glue cleaning compound. The environmentally-friendly red glue cleaning compound comprises the following components by mass: 10 to 20% of propanediol ether, 10 to 20% of glycol ether, 12 to 20% of acetate, 10 to 20% of a ketone solvent, 10 to 30% of an alcohol solvent, 5 to 15% of amines, 0.2 to 1% of a nonionic surfactant and 0.2 to 1% of anantifoaming agent, with the balance being deionized water. The environmentally-friendly red glue cleaning compound provided by the invention can rapidly and effectively dissolve components of a curedred glue during cleaning of a red glue, enables subsequent scrubbing and flushing to be more clean under the synergistic effects of components in the environmentally-friendly red glue cleaning compound, and has the characteristics of environmental friendliness, low toxicity, low volatility, good oil removal ability and good cleaning effect.

Description

Technical field [0001] The invention belongs to the technical field of fine chemicals, and specifically relates to an environmentally friendly red gum cleaning agent. Background technique [0002] During the implementation of the SMT welding process, red glue is often used to print or dispense copper clad laminates. On equipment that is in contact with the red glue, such as glue needles, printing squeegees, or steel meshes, the red glue that adheres to the surface is in the welding process The medium is cured and dried, making it difficult to clean. At present, under the current society's requirements for reducing pollution in industrial production, cleaning agents generally use halogen-free cleaning agents, such as acetone, alcohol and other oil-soluble solvents to clean equipment with solidified red glue, but a single solvent cleaning effect Poor, it is easy to have residues on the equipment, and they are all flammable and irritating substances, which are hazardous in the prod...
