Aluminium alloy paint stripper and preparation method thereof

Abstract

The invention relates to a paint stripper used for removing metal, especially removing old paint films on the surface of aluminum alloy, and also relates to a preparation method of the paint stripper. The paint stripper is characterized by consisting of the following components according to parts by weight: 70-75 parts of dichloromethane, 1-5 parts of turpentine, 0.1-0.8 part of titanium dioxide,15-20 parts of phenol, 0.1-0.3 part of defoamer NXZ, 0.2-0.9 part of Octylphenols polyoxyethylene ether, 0.6-1.2 part of hydroxyethyl celluloses, 0.8-3parts of corrosion inhibitor A-40, 1-1.4 parts of water, 0.3-0.8 part of paraffin, 1-2 parts of Vaseline, 0.01-0.1 part of corrosion inhibitor AMP-95 and 1-2 parts of deodorant. The paint stripper is applicable to depriving metal of various old paint films, characterized by quick paint stripping speed, high construction safety, small toxicity, mild gas and the like. Especially, the product has no corrosion to aluminum alloy.

Description

technical field

[0001] The invention relates to a paint remover for removing old paint films on the surface of metal—especially aluminum alloy metal, and also relates to a preparation method of the paint remover. Background technique

[0002] The paint coating on the metal surface is often peeled off with a paint stripper because it is old or unqualified. Due to the preparation method and especially the problem of the composition of the widely used paint removers, there are generally few types of removed coatings, long paint removal time, poor construction safety, strong odor, and serious damage to metals, especially aluminum alloys and light metals. Corrosion etc. Contents of the invention

[0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a kind of aluminum alloy paint remover and its preparation method, the paint remover of the present invention is a kind of fast paint removal, high efficiency, wide ran...
