Corrosion-inhibition environment-friendly water-based paint remover and preparation method thereof

Abstract

The invention discloses a corrosion-inhibition environment-friendly water-based paint remover which is prepared from the following raw materials in parts by weight: 1.2-1.4 parts of nano montmorillonite, 1.5-2 parts of penetrant T, 42-46 parts of benzyl alcohol, 11-12 parts of acetone, 10-11 parts of hydrogen peroxide, 3-3.5 parts of methyl cellulose, 2-2.4 parts of urotropine, 1.3-1.5 parts of dodecyl benzene sulfonate, 1.6-1.9 parts of microporous starch, 2.2-2.5 parts of microcrystalline wax, 0.8-1 part of tetrabutyl titanate, a right amount of ammonia water, a right amount of ethanol, 50-55 parts of water, 1-1.3 parts of tetrasodium ethylenediamine tetraacetate, 3-4 parts of nitromethane and 1-2 parts of dimethyl benzoxazole. The nitromethane can accelerate the dissolution of the paint and enhance the depainting speed; the tetrasodium ethylenediamine tetraacetate is combined to complex the dispersed and dissolved paint and metal ions to enhance the depainting effect; and the dimethyl benzoxazole can prevent metal corrosion.

Description

technical field [0001] The invention relates to the technical field of paint removers, in particular to a corrosion-inhibiting and 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 hydrocarbo...

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. The volatilization of organic solvents will pollute the environment, which needs to be improved, and the corrosion inhibition performance of the paint remover needs to be improved
