Aqueous paint remover, and preparation method and application thereof

Abstract

The invention relates to the technical field of metal coating, and concretely relates to an aqueous paint remover, and a preparation method and an application thereof. 100 parts of the aqueous paint remover comprise 1-10 parts of a monovalent alkali metal salt, 1-10 parts of a solubilizer, 1-10 parts of sodium dichloroisocyanurate, 20-40 parts of at least two organic solvents, and the balance of water. The preparation method comprises the following steps: dissolving the alkali metal salt in parts of the water, stirring and mixing the alkali metal salt and the water, sequentially adding at least three organic solvents, the solubilizer and the sodium dichloroisocyanurate, fully stirring and uniformly mixing all above materials, and finally adding the remaining water to obtain the homogenousand stable aqueous paint remover. The homogenous and stable aqueous paint remover is prepared under the action of an alkaline solution and the organic solvents through the synergism of the solubilizerand the sodium dichloroisocyanurate, can effectively dissolve all powdery coating and paint films and complex paint residues, and can effectively remove paint films from sprayed members having a special bent structure.

Description

technical field [0001] The invention relates to the technical field of metal coating, in particular to a water-based paint remover and its preparation and application. Background technique [0002] Metal surface painting is generally divided into two parts: one is the surface treatment of the metal before painting; the other is the construction of the painting. Coating construction is the process of attaching paint and coating to the metal surface by spraying, brushing, roller coating, etc., so as to protect and decorate the metal. Sometimes the painted products will produce defective products during the production process, and the coating will be damaged to varying degrees due to some external conditions, such as mechanical damage or erosion of the corrosive medium during the long-term use of the product, so it is necessary to remove the old The paint film is removed to facilitate secondary coating and utilization. [0003] The paint remover is widely used because it remo...

AI Technical Summary

Problems solved by technology

However, the water-based paint remover on the market cannot remove the workpiece with special curved structure, and it is easy to have paint film residue, so there is a big defect in the paint removal effect
