Water-soluble type alkaline paint remover and preparation method thereof

Abstract

The invention provides a water-soluble type alkaline paint remover. The water-soluble type alkaline paint remover is prepared from the following raw materials in parts by weight: 90 to 110 parts of ethylene glycol ether, 95 to 115 parts of methyl ethyl ketone, 35 to 50 parts of N-methyl-2pyrrolidone, 130 to 150 parts of aluminum magnesium silicate, 40 to 60 parts of sodium silicate, 5 to 15 parts of sodium hydrogen carbonate and 90 to 110 parts of water. A preparation method comprises: adding the water into a glass container; adding the ethylene glycol ether, stirring and dissolving; then adding the methyl ethyl ketone, the N-methyl-2pyrrolidone, the sodium hydrogen carbonate and the sodium silicate in sequence, and stirring and dissolving; finally, adding the aluminum magnesium silicate to obtain the water-soluble type alkaline paint remover. The paint remover provided by the invention has a high paint removing capability, has low toxin and is environment-friendly and is incombustible; the paint remover is a weak-alkalinity medicament, has no corrosion on a base body, is a water-soluble medicament and has no volatilization; the paint remover has no harm to the environment and human bodies and has high adaptability.

Description

technical field [0001] The invention belongs to the field of metallurgical material surface treatment, in particular to a water-soluble alkaline paint remover and a preparation method thereof. Background technique [0002] Organic coatings are widely used in daily life and industrial production. On the one hand, the role of the coating is to provide a certain protective effect on the substrate, and on the other hand, it is to beautify the appearance of the coated object. In real life, under the action of the environment and physical machinery, the coating often fails locally or in a large area with the prolongation of use time, such as loss of gloss, chalking, peeling, cracks, scratches, corrosion of the substrate, etc. Defects such as orange peel, cracks, chalking, etc. appear in the coating preparation process, resulting in the appearance of unqualified products, which requires the coating to be completely removed and re-sprayed. Mechanical removal of coatings has the di...
