Problems solved by technology

[0003] However, the paint strippers currently on the market still have certain deficiencies. They will leave traces on the steel plate when the paint is stripped, and the stripping efficiency is low
For example, the Chinese invention patent (patent number 201210315222.3, application date 2012-08-30) discloses a paint remover, which has an excellent removal effect on acrylic paint, but it will damage the steel plate itself during the paint removal process ; Chinese invention patent (patent number 201110153160.6, application date 2011-06-09) discloses a paint remover, which can effectively and quickly remove the paint film on the surface of the workpiece, thereby effectively removing the paint film without damaging the workpiece. However, the scope of application of the paint remover is narrow, and it will still damage the steel plate if it stays on the surface of the steel plate for a long time

Abstract

The invention provides a steel plate paint remover and a preparation method thereof. The paint remover comprises the following raw materials in parts by mass: 55-75 parts of sodium gluconate, 12-22 parts of benzoic acid, 4-12 parts of diacetone alcohol, 4-12 parts of amyl acetate, 0.8-2.5 parts of hydroxypropyl cellulose, 1-3 parts of castor oil, 0.7-2 parts of dimethyl cellosolve, 1.5-7 parts of banana oil, 0.6-1.5 parts of sodium dodecylbenzenesulfonate, 0.6-1.5 parts of dimethyl adipate and 1-3 parts of polyethylene glycol. By the paint remover provided by the invention, various paints on the surface of the steel plate can be removed, no traces or residue is caused, the matrix cannot be corroded and the removal efficiency is high.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a steel plate paint remover and a preparation method thereof. Background technique [0002] The paint remover is a liquid composed of aromatic compounds and high-solvent solvents. It has a strong ability to dissolve paint films. The paint remover is fast and efficient. It can remove a wide range of coatings and is suitable for alcohol Acid, nitro, polyurea rubber type vinyl, epoxy, polyester, polyurethane and other paints. [0003] But, the paint stripper still exists certain deficiency in the market at present, can leave mark on steel plate when stripping, and stripping efficiency is low. For example, the Chinese invention patent (patent number 201210315222.3, application date 2012-08-30) discloses a paint remover, which has an excellent removal effect on acrylic paint, but it will damage the steel plate itself during the paint removal process ; Chinese invention patent (patent number 20111...
