Problems solved by technology

However, for the paint or primer on the surface of metal workpieces, surfactants alone cannot completely remove them. Therefore, some organic solvents are usually used for cleaning, such as chloroform, acetone and other single organic solvents. The selected coatings or primers have different compositions, have different bonds, and the treatment effect of a single organic solvent is not good. Therefore, the prior art also uses a combination of several organic solvents to achieve the purpose of thorough removal, but the existing The solvent combination formulations have the following problems: some solvent combinations can only remove a specific type of paint or primer, or some solvent combinations can remove a variety of substances, but the versatility is not strong, and in fact it can only remove one Class-specific substances are nothing more than certain effects on other classes of substances

[0015] 4) The treatment environment is 25°C, a...

Embodiment 2

[0017] In this embodiment, except that the composition of the treatment agent is changed, other conditions are the same as in Example 1, including the detection experiment, so it will not repeat the description. In the following examples, the composition of the treatment agent also changes. Others were unchanged, and the test results are shown in Table 1.

[0018] Prepare the treatment agent in weight percentage, wherein 1,1,1-trichloroethane 20%, chloroform 6%, dichloroethane 25%, acetone 30%, epichlorohydrin 8%, ethanol 11%, the above Composition Prepare the solution at room temperature.

Embodiment 3

[0020] Prepare treatment agent in weight percentage, wherein 1,1,1-trichloroethane 22%, chloroform 8%, dichloroethane 20%, acetone 25%, epichlorohydrin 8%, ethanol 17%, will above Composition Prepare the solution at room temperature.

Abstract

The present invention relates to an aluminum alloy surface treatment agent, which comprises, by weight, 20-25% of 1,1,1-trichloroethane, 6-9% of trichloromethane, 15-25% of dichloroethane, 22-30% of acetone, 6-8% of epichlorohydrin, and 10-25% of ethanol.

Description

Background technique [0001] The invention belongs to the field of metal surface treatment, in particular to an aluminum alloy surface treatment agent. Background technique [0002] During the processing or use of aluminum alloy, there will be oil stains or paints, primers and other substances. Therefore, cleaning and other procedures must be carried out during the processing process. During the cleaning process, surfactants are generally added to remove oil stains In order to achieve the purpose of thorough cleaning. However, for the paint or primer on the surface of metal workpieces, surfactants alone cannot completely remove them. Therefore, some organic solvents are usually used for cleaning, such as chloroform, acetone and other single organic solvents. The selected coatings or primers have different compositions, have different bonds, and the treatment effect of a single organic solvent is not good, so the prior art also uses a combination of several organic solvents t...
