Abstract

The invention discloses a novel harmless and efficient paint remover and a preparation method of the novel harmless and efficient paint remover. The novel harmless and efficient paint remover comprises the following components: 70 to 90 parts of diglycol diethyl ether acetic ester, 5 to 10 parts of benzaldehyde, 2 to 9 parts of organic acid, 1 to 4 parts of emulsifying agent, 1 to 2 parts of thiourea, and 1 to 7 parts of liquid paraffin, wherein the emulsifying agent is OP-10, sodium dodecyl benzene sulfonate or the mixture of OP-10 and sodium dodecyl benzene sulfonate. The paint remover prepared by the preparation method disclosed by the invention is low in volatility, harmless, safe to a metal substrate, harmless to operators or environments, convenient and quick to construct, excellent in paint removing performance, low in raw material cost, and applicable, simple and convenient to operate.

Description

technical field [0001] The invention relates to a paint remover. In particular, it relates to a low-toxicity and high-efficiency paint remover and a preparation method thereof. Background technique [0002] The surface of various objects is protected by coating, but because the object is subjected to steam, temperature, sunlight, atmosphere, dust and sand friction, biological influence, corrosion of chemical harmful substances and changes in the surface of the coating base material during use and so on, the coating is damaged and loses its protective effect, so it must be repainted. In this case, the old paint film on the surface of the product should be removed first. The removal of the old paint film is determined according to the damage of the old paint film and the requirements of the protective coating, and can be completely removed or partially removed. Commonly used methods are mechanical and chemical. The traditional mechanical method of removing paint film, such...
