Example Embodiment

[0030] Example 1:

[0031] At room temperature, add 20.0g of benzyl alcohol, 20.0g of ethylene glycol, 0.2g of sodium cetylbenzene sulfonate, 1.0g of emulsified silicone oil and 58.8g of water into a clean 250ml beaker, and stir for 2 minutes Until fully mixed and uniform, 100 g of the degumming agent of the present invention is obtained.

[0032] Put the aluminum-plated film sample with the aluminum-plated layer and composite adhesive on the surface into the prepared degumming agent, and scrape off by friction. The adhesive layer can be easily scraped off in 10 seconds at room temperature to expose the bright surface of the aluminum-plated layer. The degumming agent was recycled for 30 minutes in the washing machine, and only a small amount of foam was produced.

Example Embodiment

[0033] Example 2

[0034] At room temperature, add 33.0g of benzyl alcohol, 33.0g of N-methylpyrrolidone, 0.5g of cetyltrimethylammonium bromide, 1.5g of polyoxypropylene glyceryl ether and 32.0 to a clean 250ml beaker. g of water, stirred for 2 minutes until fully mixed uniformly, to obtain 100 g of the degumming agent of the present invention.

[0035] Put the aluminum-plated film sample with the aluminum-plated layer and composite adhesive on the surface into the prepared degumming agent, and scrape it off by friction. The adhesive layer can be easily scraped off in 6 seconds at room temperature to expose the bright surface of the aluminum-plated layer. The degumming agent was recycled for 30 minutes in the washing machine, and only a small amount of foam was produced.

Example Embodiment

[0036] Example 3

[0037] At room temperature, add 39.0g of phenethyl alcohol, 38.2g of n-propanol, 0.8g of cetyltrimethylammonium bromide, 2.0g of polyoxypropylene polyoxyethylene glyceryl ether and 20.0g of water is stirred for 2 minutes until fully mixed uniformly to obtain 100g of the degumming agent of the present invention.

[0038] Put the aluminized film sample with aluminized layer and composite glue on the surface of the prepared degumming agent, and scrape it off by friction. The glue layer can be easily scraped off in 12 seconds at room temperature to expose the bright surface of the aluminized layer. The degumming agent was recycled for 30 minutes in the washing machine, and only a small amount of foam was produced.

Abstract

A water-based adhesive removal agent for a plastic film for package printing is prepared from components in percentage by weight as follows: 17%-40% of a main solvent, 17%-40% of a cosolvent, 0.05%-5% of a surfactant, 0.5%-5% of an antifoaming agent and 20%-60% of water. With use of a swelling action of effective ingredients in the adhesive removal agent on a composite adhesive, a composite adhesive layer on the surface of the film is swelled rapidly to fall off. Under the action of the antifoaming agent, the adhesive removal agent cannot produce a large amount of foam when reused in a cleaning machine. The adhesive removal agent has the characteristics that a preparation method is simple, the adhesive removal agent is stable and not prone to delamination or volatilization, the adhesive is removed rapidly, damage to a film substrate is not produced, heating is not needed when the adhesive removal agent is used at the room temperature, the adhesive removal agent can be reused in the cleaning machine, a large amount of foam cannot be produced and the like.

Description

technical field [0001] The invention relates to a degumming agent used in the packaging and printing industry, in particular to a degumming agent for plastic films used in packaging and printing. Background technique [0002] Vacuum aluminum-coated paper is widely used in the packaging of cigarette packs, wine packs, food, cosmetics, gifts, handicrafts, and daily necessities due to its bright color, strong metallic feeling, and bright and elegant prints. At present, vacuum aluminized paper can be divided into direct evaporation method and transfer evaporation method according to its production process. Among them, the transfer evaporation method is to glue the PET film after vacuum aluminum plating and compound it with cardboard, and then peel off the PET film, and the aluminum molecules are transferred to the surface of the cardboard through adhesion. The transfer evaporation method is further divided into full-format transfer and partial transfer. After the aluminized fi...
