Abstract

The invention provides an environment-friendly aqueous paint remover. The environment-friendly aqueous paint remover is characterized by being prepared from, by weight, 15-20% of phenylcarbinol, 20-28% of paratoluenesulfonic acid sodium salt, 6.0-8.0% of potassium hydroxide, 3.0-4.0% of sodium gluconate, 2-5% of a cosolvent and 30-40% of tap water. The environment-friendly aqueous paint remover has the advantages of being environmentally friendly, free of toxicity, free of damage to base materials, capable of being repeatedly applied and low in integrated cost.

Description

technical field [0001] The invention belongs to the field of paint stripping coatings, and provides a heat-soaking and environment-friendly water-based paint stripper, which is a liquid that is non-toxic, harmless to the environment, and has low cost. The main solvent is water, and the operation is safe. Simultaneously, the present invention also relates to the preparation method and application of the paint remover, which brings immeasurable benefits to the paint remover industry. Background technique [0002] Coatings can protect and decorate objects, but in the process of use, the coating film will be damaged, or gradually aged, or repaired and renewed for aesthetic reasons. Regardless of the coating or repair of household appliances, mechanical equipment, furniture, vehicles and ships, etc., it is necessary to remove the old or damaged coating before spraying. Traditional paint strippers mainly use methylene chloride as a solvent, such as methylene chloride, which has t...
