Environment-friendly and efficient paint-removing composition

Abstract

The invention provides an environment-friendly and efficient paint-removing composition. The environment-friendly and efficient paint-removing composition is prepared from the following raw materials in parts by weight: 30 to 45 parts of dibasic ester, 5 to 15 parts of dipropylene glycol methyl ether, 5 to 8 parts of benzyl alcohol, 15 to 25 parts of water, 0.5 to 2 parts of benzotriazole, 1 to 5 parts of formic acid, 1 to 5 parts of boric acid, 8 to 15 parts of ethanol, 0.5 to 1.5 parts of NP-10, 2 to 6 parts of sodium gluconate and 0.01 to 1 part of polyepoxysuccinic acid. The environment-friendly and efficient paint-removing composition is green and environmental-friendly, is not easy to combust and explode, has high paint removing efficiency and wide application range, is safe and non-toxic, and has various functions of removing paint, washing, preventing rusting and the like; the environment-friendly and efficient paint-removing composition is a product with extremely high cost performance; the labor intensity of paint removing work can be greatly reduced, and the paint removing cost is remarkably reduced.

Description

technical field [0001] The invention relates to the technical field of paint removers, in particular to a safe and environment-friendly water-soluble high-efficiency paint remover composition. Background technique [0002] The paint film is usually thermoplastic resin and room temperature cross-linking curing resin, such as alkyd resin, nitro paint, epoxy resin, polyurethane paint, silicone epoxy resin paint, etc. The paint film of these polymers can dissolve Or swell in an appropriate organic solvent, and these polymer molecules contain certain active functional groups, such as ester bonds, ether bonds, amide bonds, etc., which are prone to acidolysis and alkali hydrolysis under the action of hot acid or alkali The chemical reaction causes its molecular chain to break, so the old paint film is easily removed by organic solvent paint remover or alkaline paint remover, acid paint remover. [0003] The function of the paint remover is to destroy the spatial structure of the p...

But unavoidably, these organic solvents all have certain toxicity, and volatilize fast, pollute the air

For example: some paint removers are solvent-based paint removers with dichloromethane as the main solvent. Among the chlorinated alkanes derivatives, dichloromethane is the lightest liquid compound with small molecular weight, low molecular energy and strong penetration; However, dichloromethane is highly toxic, volatilizes quickly, and is easily inhaled by the operator, posing a threat to the health of the operator. At the same time, the solvent volatilizes into the air, which will also cause damage to the ozone layer.

Moreover, some paint removers use paraffin as a thickener. The use of paraffin not only increases the viscosity of the solvent, but also reduces the volatility of the solvent. Although the effect is good, it is difficult to remove and it is difficult to carry out the second painting
