Embodiment 1

[0034] Paint remover formula (wt%): benzyl alcohol 24%, isobutyl acetate: 15%; Anisole 5%, ethanolamine 10%, activator (methyl alcohol): 10%; Emulsifier (dodecylbenzene sulfonate Sodium Acid): 3%; Water: 33%.

[0035] Preparation method: (1) Dissolve sodium dodecylbenzene sulfonate in water at 30(±1)°C, stir for 10min to dissolve completely. (2) Add the main solvent (benzyl alcohol, isobutyl acetate), co-solvent (anisole, ethanolamine), and activator (methanol) into another container, and stir to make it evenly mixed. (3) Add the mixed solution in step (2) into the aqueous solution in step (1), stir for 30 minutes, and mix evenly to obtain the prepared paint remover.

Embodiment 2

[0037] Paint remover formula (wt%): benzyl alcohol 42%, isobutyl acetate 13%; Anisole 4%, ethanolamine 4%; Activator (ethanol): 5%; Emulsifier (dodecylbenzenesulfonic acid Sodium): 4%; Water: 28%.

Embodiment 3

[0039] Paint remover formula (wt%): benzyl alcohol 27%, isobutyl acetate 14%; Anisole 5%, ethanolamine 5%; Activator (n-propanol): 7%; Emulsifier (dodecyl sulfonate Sodium Acid): 5%; Water: 37%.

Abstract

The invention discloses a room-temperature aqueous paint remover and preparation and use methods thereof. The paint remover comprises, by mass, the following components: 13-43% of benzyl alcohol, 6-28% of isobutyl acetate, 3-12% of anisole, 3-18% of ethanolamine, 3-15% of activator, 1-6% of emulsifier and 15-45% of water, wherein the mass ratio of benzyl alcohol to isobutyl acetate is 3:1-3:2, themass ratio of anisole to ethanolamine is 1:1-1:3. The aqueous paint remover has the advantages of environmental protection, quick paint removal, low energy consumption and room-temperature operation.

Description

technical field [0001] The invention belongs to the technical field of paint removers, and in particular relates to a normal-temperature water-based paint remover and a preparation method thereof. Background technique [0002] Whether it is engineering application or civil industry, surface coating has become an indispensable technology. During the use of the product, the paint film will be damaged or aged over time. For the sake of beauty, the old paint needs to be removed and re-sprayed. Or the defective products in the recycling coating process also need to remove the paint film on the surface of the product and repaint it. There are many ways to remove paint film, for example, mechanical method, flame method, lye method, paint stripper method. Wherein, the paint remover is widely used because of its advantages such as high paint removal efficiency. However, most of the traditional paint removers contain volatile and highly toxic substances such as methylene chloride a...
