Nano-aluminium powder modified environment-friendly aqueous paint remover and preparation method thereof

Abstract

The invention discloses a nano-aluminium powder modified environment-friendly aqueous paint remover, which is prepared from the following raw materials in parts by weight: 1.2 to 1.4 parts of nano-montmorillonite, 1.5 to 2 parts of penetrating agent T, 42 to 46 parts of benzyl alcohol, 11 to 12 parts of acetone, 10 to 11 parts of hydrogen peroxide, 3 to 3.5 parts of methylcellulose, 2 to 2.4 parts of urotropin, 1.3 to 1.5 parts of dodecyl benzene sulfonate, 1.6 to 1.9 parts of micro-porus starch, 2.2 to 2.5 parts of microcrystalline wax, 0.8 to 1 part of tetrabutyl titanate, a proper amount of ammonium hydroxide, a proper amount of ethyl alcohol, 50 to 55 parts of water, 0.8 to 1 part of sodium sulfite, 0.4 to 0.6 part of nano-aluminium powder and 0.6 to 0.8 part of oxalic acid. Through using the sodium sulfite, the nano-aluminium powder and the oxalic acid, the aqueous paint remover provided by the invention can permeate to a paint film bonding interface, foam, promote paint film stripping and improve paint removing efficiency.

Description

technical field [0001] The invention relates to the technical field of paint removers, in particular to a nano aluminum powder modified environment-friendly water-based paint remover and a preparation method thereof. Background technique [0002] Traditional chlorinated alkanes supplemented with benzene-based paint strippers are highly toxic and highly polluting. Although they can efficiently remove the paint film on the substrate, they also cause great harm to the environment and operators. In recent years, it has been a research hotspot to develop a new type of low-pollution environment-friendly paint remover. The article "Research Progress of Environmentally Friendly Paint Strippers" briefly introduces the working principle and types of paint strippers, focuses on the composition of environmentally friendly paint strippers, and looks forward to the development trend of paint strippers in the future . [0003] Most of the traditional paint strippers use chlorinated hydro...

Problems solved by technology

The article "A New Emulsion-type Paint Remover" introduced the specific preparation method of the emulsion-based paint remover, and obtained a paint remover with better performance, but there is still a big gap between the paint-removing effect and the oil-based paint remover. Volatilization of organic solvents will pollute the environment and need to be improved
