Embodiment 1

[0021] This embodiment is used to illustrate the paint stripper composition provided by the invention.

[0022] Dissolve 40 grams of phenol in 360 grams of 40°C hot water, stir until fully dissolved, and then cool to 25°C. Add 50 grams of ethanol to the phenol solution, and finally add 50 grams of water, and stir well to obtain the paint remover composition T1.

Embodiment 2-6

[0024] These examples illustrate the paint stripper compositions provided by the present invention.

[0025] According to the same method and steps as in Example 1, paint remover compositions T2-T6 were respectively obtained, and their compositions are shown in Table 1.

Embodiment 7-12

[0033] These examples are used to illustrate the paint stripping method provided by the present invention.

[0034] ABS / PC (manufacturer of ABS / PC is German Bayer company, model is FR86) substrate [45 (± 4mm) × 296.9 (± 0.5mm) × 1.2 (± 0.3 mm)] and polypropylene resin substrate [45 (± 4mm) × 296.9 (± 0.5mm) × 1.2 (± 0.3mm)] (manufacturer is South Korea SK, model is T131N) soaked in above-mentioned embodiment 1-6 respectively In the prepared paint remover compositions T1-T6, the paint was removed at the temperature shown in Table 2, and the time for removing the paint film was recorded. The results are shown in Table 2 below. The time for removing the paint film refers to the time elapsed from the time when the base material is soaked into the paint remover composition until the surface of the base material is observed with the naked eye until the paint film cannot be seen.

Abstract

The invention provides a paint remover composition, wherein the composition contains phenol, alcohol and water; taking total amount of the composition as a standard by weight percent, the content of the phenol is 6-11 percent, the content of the alcohol is 5-20 percent, and the content of the water is 70-89 percent. The invention also provides a method of removing paint, which comprises the following step: mixture is contacted with a paint film positioned on the surface of base material, wherein the mixture is the composition provided by the invention. The paint remover composition can effectively remove an old paint film on the surface of polyolefine resin and PC mixed base material, in particular ABS / PC base material, and has no damage to the base material under a mild condition. The paint remover composition can also effectively remove the paint film on the surface of other plastic base materials, in addition, the base materials after paint removal can be painted and used for the second time, and the secondary injection of the base material is deleted, thereby saving the process steps and the production cost.

Description

technical field [0001] The invention relates to a paint remover composition and a paint removal method using the composition. Background technique [0002] For the beauty of old products, the process of repainting after stripping the old products is usually carried out. Spraying fixtures are often used in the spraying process, which are generally formed by mixing two different plastic materials, such as acrylonitrile-butadiene-styrene (ABS) and polycarbonate (PC). )form. During the spraying process, the sprayed material continues to accumulate on the surface of the fixture. When the coating reaches a certain thickness, the fixture cannot be reused, which will greatly increase the production cost. In order to reduce the production cost, it is necessary to remove the coating on the surface of the jig to reuse the jig. [0003] At present, commonly used paint removers are divided into two categories: inorganic paint removers and organic paint removers. Inorganic paint remov...
