Abstract
The present invention provides a film removing agent for removing electrostatic painting powder and baking finish coatings and a preparation method thereof. The film removing agent is prepared from butyl acetate, formic acid, cresol, phynol, propanone and cyclohexanone, and the preparation method comprises: the formic acid, the cresol, the phynol, the cyclohexanone and the propanone which have predetermined shares are orderly put in a container containing the butyl acetate; the materials are stirred and uniformly mixed. Film removing treatment is carried out to the powder coating sample of Zhongfa Company by the film removing agent, and the coatings foam within two to five minutes and can be completely shed off within 10 to 25 minutes. The film removing agent can be repeatedly used for multiple times.
Description
The present invention discloses a kind of remover and compound method of removing electrostatic spraying powder and baking vanish coating, belongs to the chemical coating remover.
Electrostatic spraying powder and baking vanish can form the coating of a secluding air and water on metal substrate.Because this coating is strong, incrust with putting forth effort, can protect metal sheet to exempt corrosion effectively, coating is bright-coloured simultaneously, and its product has increased aesthetic feeling.Therefore, electrostatic spraying powder and baking vanish technology are very extensive in industrial application.But, for faulty finish, how to remove, clear up, but be a very stubborn problem.Usually, the single organic solvent dissolution method is adopted in the processing of faulty finish in the production more.This method removes that to be coated with interval velocity slower, and coating removes thoroughly inadequately, and simultaneously, metal substrate is subjected to solvent and invades the spot that easily gets rusty after the stain, and is unfavorable to applying again.Also exist the low shortcoming of solvent recycling number of times.
Purpose of the present invention promptly is the above-mentioned deficiency at the single organic solvent dissolving technology, provides a kind of removing faulty finish speed fast, thorough, and substrate metal is not produced corrosion, and a kind of remover and the preparation method that can be repeatedly used.
Remover provided by the present invention is made up of six kinds of organism mixing, comprises cresols, phenol, formic acid, N-BUTYL ACETATE, acetone, pimelinketone.Wherein cresols, phenol have the performance of the sticking power that reduces rete and metal substrate.Pimelinketone, acetone, formic acid then make its rete expand, and break away from not produce the metal substrate of deformation.N-BUTYL ACETATE then has the coordinative role that above-mentioned each component evenly is miscible in together, effectively brings into play demoulding, and can avoid the solvent corrosion metal substrate.
The each component of remover, to calculate share by volume as follows:
(1) N-BUTYL ACETATE 20-31
(2) formic acid 21-26
(3) cresols 17-20
(4) phenol 1-2
(5) acetone 13-17
(6) pimelinketone 5-7.
The compound method of remover comprises following step:
1. the formic acid of predetermined fraction is inserted in the load weighted N-BUTYL ACETATE container;
2. predetermined fraction cresols is inserted in the container of splendid attire N-BUTYL ACETATE, formic acid;
3. with behind phenol, pimelinketone, the acetone weighing successively, insert in turn in the aforementioned container;
4. stir with agitator or clean wooden stick and get final product.
Utilize this remover, Yingkou Washing Machine Factory has been sprayed the model of method company powder coating in the Hangzhou, the powdered epoxy coating model of Shenyang Resin Factory, carry out demoulding and handle.Impregnated coating was bubbled in the time of 3-5 minutes, all came off in 10 minutes.To Shenyang Medical Apparatus and Instruments Factory dust before parkerized polyester epoxy powder rete, flood foaming in 5 minutes, all came off in 25 minutes.And this remover can be repeatedly used.
Further describe its inventive features below by preferable embodiment of the present invention:
The remover each component, to calculate share by volume as follows:
1. N-BUTYL ACETATE 23-28
2. formic acid 24-26
3. cresols 18-20
4. phenol 2
5. acetone 17
6. pimelinketone 7.
Each component raw material in the remover of the present invention, its purity are the technical pure level.
Remover of the present invention, the demoulding that also can be used for enamelled coating on the plank is handled, and the demoulding effect is also very desirable.
