Embodiment 1

[0028] As an aspect of the present invention, provide a kind of preparation method of paint stripper for ABS plastic base material, described paint stripper is used for removing vacuum electroplating aluminum and coating on ABS plastic base material simultaneously, described method comprises as follows step:

[0029] Choose the raw material of following mass percentage:

[0030]

[0031] Wherein, in a specific example, the ratio of each raw material is as follows by weight:

[0032] Sodium hydroxide 5%;

[0033] Low molecular alcohol 29.5%;

[0034] Alcohol ether compounds 30%;

[0035] Aliphatic hydrocarbons 25%;

[0036] water 10%;

[0037] Surfactant 0.5%.

[0038] First prepare the aforementioned sodium hydroxide and water into a sodium hydroxide solution, then add low-molecular alcohol and one-half amount of alcohol ether compounds, after the phase state is stable, add aliphatic hydrocarbons and another half alcohol ether compounds, and finally A surfactant is a...

Embodiment 2

[0047] As another aspect of the present invention, a paint remover for ABS plastic substrates is also provided, which is prepared by the preparation method described in the first embodiment above.

Embodiment 3

[0049] As another aspect of the present invention, also provide a kind of use method for the paint stripper of ABS plastic substrate, it comprises steps:

[0050] Choose the paint stripper that is used for the ABS plastic base material in the aforementioned embodiment two;

[0051] Soak all the workpieces to be depainted in the paint remover, or use a brush or cotton yarn to smear the paint remover on the parts of the workpiece to be depainted;

[0052] After waiting for 5-120 minutes, rinse the residual paint flakes on the surface of the workpiece to be depainted with water.

[0053] It can be understood that the embodiment of the present invention provides a paint stripper for ABS plastic substrates, the paint stripping principle is: aliphatic hydrocarbon dissolves or swells the resin, destroys topcoat, primer coating on metal plating, substrate Excellent surface adhesion, but no corrosion or damage to the ABS substrate; sodium hydroxide reacts with the vacuum electroplatin...

Abstract

The invention discloses a paint remover for an ABS plastic base material, and a preparation method and a use method thereof. The paint remover comprises, by mass, 3-8% of sodium hydroxide; 10-40% of low molecular alcohol; 10-40% of an alcohol ether compound; 10-40% of aliphatic hydrocarbon; 2-20% of water; and 0.1-0.5% of a surfactant. A vacuum electroplating aluminum coating, a styrene modified alkyd resin primer coating and a nitrocellulose finish coating on the ABS base material can be removed, the base material is not damaged, recycling of the base material is facilitated, and the paint remover is safe, free of pollution, practical, efficient, low in raw material cost, easy in raw material obtaining, and beneficial to popularization.

Description

technical field [0001] The invention relates to the technical field of paint remover for toy surfaces, in particular to a paint remover for ABS plastic substrates and a preparation method and application method thereof. Background technique [0002] As a surface decoration technology, vacuum electroplating aluminum widely exists in process manufacturing, but it cannot exist alone. It needs a primer (such as styrene-modified alkyd resin self-drying paint) to provide adhesion on the material, that is, the substrate. At the same time, a top coat (such as nitrocellulose-based paint) is required to protect it from corrosion and scratches. It is generally used for vacuum electroplating aluminum in the fields of toys, gifts, stationery, cosmetics, etc. It is different from the UV fast curing (ultraviolet light curing) vacuum electroplating aluminum system commonly used in the electronics industry, in terms of performance, crosslinking degree, and construction efficiency. It is inf...
