Metal paint remover and preparation method thereof

Abstract

The invention discloses a metal paint remover and a preparation method thereof. The paint remover comprises the following components in parts by weight: 50-60 parts of formic acid, 10-20 parts of ethyl acetate, 3-8 parts of methanol, 10-20 parts of dichloromethane, 30-50 parts of thinner, 2-6 parts of ethanolamine, 3-8 parts of sodium alkyl benzene sulfonate, 1-5 parts of polyglycerol fatty acid ester, 2-6 parts of butylcellosolve, 1-5 parts of paraffin and 2-7 parts of organic glass powder. The preparation method comprises the following steps: heating to melt paraffin, slowly adding dichloromethane, stirring to completely dissolve the paraffin, adding the other components, and stirring uniformly at the speed of 1500-1800 rpm. The test indicates that the paint removal time of the metal paint remover disclosed by the invention is within 75 seconds, and the paint removal effect can be achieved within 35 seconds at the soonest; and the components of the paint remover are cheap and accessible, and therefore, the metal paint remover has high application value.

Description

technical field [0001] The invention belongs to the field of metal surface treatment, in particular to a metal paint remover and a preparation method thereof. Background technique [0002] Paint is a kind of chemical mixture coating that can firmly cover the surface of the substrate and play a role in protection, decoration, marking or other functions on the substrate. It usually consists of liquid vehicle and solid pigment. This kind of coating can be coated on the surface of objects by different construction techniques to form a continuous solid film with strong adhesion and certain strength. Metal surfaces can be protected by paint or beautified by paint. However, these objects will be damaged due to physical and chemical effects in the process of eating, losing their protection and beautification, so they need to be repainted. Before painting, the old paint film on the surface of the metal object must be removed. There are usually two methods for removing the old paint...

Problems solved by technology

Organic paint remover is the mainstream product in the market at present, with many types and wide applications, but at present, such products usually contain toxic and volatile components such as phenol and chloroform, which have a relatively high impact on the environment and the safety of operators At the same time, the quick-cleaning performance of this type of product is poor. It usually takes tens of minutes to clean the old paint on the surface of the object. Not only does it have requirements for the use environment, but the use efficiency is not high
