Embodiment approach

[0037] For an implementation, see figure 1 , a preparation method of enameled wire paint stripper, comprising the following steps:

[0038] S110. Mixing ketones and amides to obtain a first mixture, wherein the mass ratio of the ketones to the amides is (20-70):(10-50).

[0039] By mixing ketones and amides, of course, an appropriate amount of pure water can also be added, after fully dissolving and stirring uniformly, the first mixture can be obtained, which is convenient for subsequent preparation to obtain enameled wire paint remover, wherein the ketones and the The mass ratio of amides is (20-70): (10-50). It can be understood that if the same material is used in different proportions, the performance of the obtained mixture may be very different. In this embodiment, by controlling the The specific ratio of the ketones and the amides can make the ketones and the amides play a better synergistic effect, which is beneficial to the preparation of an enameled wire paint remov...

Embodiment 1

[0049] 450g of methyl isobutyl ketone, 200g of 1,1,3-trimethylcyclohexenone, 100g of formamide, and 206g of N,N-dimethylacetamide were mixed to obtain the first mixture;

[0050] At normal temperature and normal pressure, 20g of triethylenetetramine and 10g of triethanolamine were put into the first mixture for dissolving operation to obtain the second mixture;

[0051] In the second mixture, add 10g polyethylene glycol, 1.5g MBT-Na, 1g succinic acid, 1.5g hydroxyethyl cellulose successively, stir until transparent state, obtain the enameled wire paint remover of embodiment 1;

[0052] Under the temperature condition of 110° C. to 150° C., the enameled wire is soaked in the enameled wire paint remover of Example 1, and the paint stripping operation is performed for 30S to 120S, so that the paint film on the enameled wire is dissolved and peeled off.

Embodiment 2

[0054] 450g of N-vinylpyrrolidone, 200g of propiophenone, 170g of N,N-dimethylformamide, and 136g of N,N-dimethylacetamide were mixed to obtain the first mixture;

[0055] At normal temperature and normal pressure, 20g of tetraethylenepentamine and 10g of triethanolamine were put into the first mixture for dissolving operation to obtain the second mixture;

[0056] In the second mixture, add 10g polyethylene glycol, 1.5g REOMENT-3, 1g inactive rosin flux, 1.5g polyvinyl alcohol successively, stir until transparent state, obtain the enameled wire paint remover of embodiment 2;

[0057] Under the temperature condition of 110° C. to 150° C., the enameled wire is soaked in the enameled wire paint remover of Example 2, and the paint stripping operation is performed for 30 s to 120 s, so that the paint film on the enameled wire is dissolved and peeled off.

Abstract

The invention relates to the field of paint removers, and discloses an enameled wire paint remover and a preparation method thereof. The enameled wire paint remover is prepared from the following components in parts by mass: 20 to 70 parts of ketone, 10 to 50 parts of amide, 1 to 30 parts of organic alkali, 0.1 to 10 parts of a volatile inhibitor, 0.1 to 8 parts of a corrosion inhibitor, 0.1 to 5parts of soldering flux and 0.1 to 3 parts of a thickening agent, wherein the ketone is one or more of 1-vinyl-2-pyrrolidinone, 1,1,3-trimethyl cyclohexenone, 4-methyl-3-penten-2-one, methylisobutyl ketone, propiophenone and methyl cyclohexanone. The enameled wire paint remover is more efficient and thorough in paint removal; the problem of metal material corrosion can be effectively avoided; goodcorrosion resistance of a metal material can be guaranteed, and the welding firmness can be improved; the paint remover is free of halogen and heavy metal, harm to human bodies and the environment issmall, and the paint remover is lower in toxicity and more environmentally friendly; in addition, the paint remover is convenient to use and only need heating and soaking. The paint remover is generally suitable for removing the varnish coating of the enameled wire.

Description

technical field [0001] The invention relates to the field of paint removers, in particular to an enameled wire paint remover and a preparation method thereof. Background technique [0002] Enameled wire is a main variety of winding wire, which is composed of conductor and insulating layer. After the bare wire is annealed and softened, it is painted and baked many times. Enameled wire is widely used in industry, but in the process of use, there will be some problems, such as welding is not firm, because the paint film on the enameled wire will weaken the firmness of the welding part, so before welding, it is necessary to weld Parts of the enameled wire for paint stripping treatment. In addition, when recycling enameled wires, in order to obtain clean bare wires, it is also necessary to use enameled wires to remove the paint on the surface of the wires. [0003] However, many existing enameled wire paint strippers contain halogenated hydrocarbons and even heavy metal compone...
