Problems solved by technology

For convenience and beauty, we sometimes paste some transparent glue on the glass, but after tearing off, the glass is full of traces of transparent glue
The utility poles in the streets are covered with all kinds of small advertisements, which are quite difficult to clean and seriously affect the appearance of the city.
The most troublesome problem on motor vehicles is the glue left on the front windshield after the car inspection, which is extremely difficult to handle, and it also particularly hinders the appearance of the car
For the purpose of publicity, we often see vendors paste some small advertisements on the panels of the elevators. For better pasting effect, most of them use double-sided tape to complete, but after the advertisements are removed, some ugly glues are often left behind. If we use mechanical methods to remove it, it will scratch some organic paint on the surface of the decorative material

Embodiment 1

[0023] (1) Take 10 mL of 95% ethanol, 8 mL of acetone, 12 mL of ethyl acetate, 10 mL of 28% ammonia water, 1 mL of OP emulsifier, 3 mL of N,N-dimethylformamide, 4 Add mL turpentine and 0.3 mL spices into a 200 mL beaker, stir for 10 minutes under normal temperature and pressure at 500-1000 rpm, and bottle for later use.

[0024] (2) Erasing effect: Paste the double-sided adhesive on the solid wood particle board with a flat surface one day in advance, place it under normal temperature and pressure for one day, and then spray the prepared erasing solution (1) directly on the double-sided adhesive, After waiting for 3 minutes, the rubber surface softens and deforms, which can be wiped off with a cloth without leaving any traces.

Embodiment 2

[0026] (1) Take 10 mL of 95% ethanol, 5 mL of acetone, 20 mL of ethyl acetate, 10 mL of 28% ammonia water, 1 mL of OP emulsifier, 3 mL of N,N-dimethylformamide, 8 mL Add turpentine and 0.5 mL spices into a 200 mL beaker, stir for 10 minutes under normal temperature and pressure at 500-1000 rpm, and bottle for later use.

[0027] (2) Erasing effect: tear off the label paper on the surface of the penicillin glass vial, leaving a lot of glue marks, spray the above (1) wiper solution directly on the glue marks, and wait for 5 minutes before the glue surface softens Deformation occurs and can be wiped off with a cloth without leaving traces.

Embodiment 3

[0029] (1) Take 15 mL of 95% ethanol, 10 mL of acetone, 15 mL of ethyl acetate, 7 mL of 28% ammonia water, 2 mL of OP emulsifier, 4 mL of N,N-dimethylformamide, 10 Add mL turpentine and 0.3 mL spices into a 200 mL beaker, stir for 10 minutes under normal temperature and pressure at 500-1000 rpm, and bottle for later use.

[0030] (2) Erasing effect: tearing off the advertising stickers on the street wall will leave a lot of glue marks, then spray the eraser prepared in (1) above directly on the glue marks, and wait for 7 minutes before the glue surface Softened and deformed, it can be wiped off with a cloth without leaving traces.

Abstract

The invention relates to a bottom glue erasing liquid for cleaning bottom glue residue of non-setting adhesives, instant plasters, double-sided adhesives, and other products of the kind. The bottom glue erasing liquid comprises the following components by volume fraction: 6% ~ 35% of acetone; 10% ~ 40% of ethyl acetate ethanol; 15% ~ 30% of ethanol; 1% ~ 4% of OP emulsifier; 10% ~ 25% of ammonia; 3% -10% of N,N- dimethylformamide; 5% ~ 20% of turpentine; and 0.2% ~ 2% of a spice. The components are mixed proportionally and stirred in 500 ~ 1000 rpm / min for 5 to 30 minutes to obtain the bottom glue erasing liquid, the bottom glue erasing liquid is directly sprayed on glue mark surface, after waiting for 3 to 15 minutes, the glue mark surface is softened and deformed, and then is wiped with a cloth, and no mark is left.

Description

technical field [0001] The invention relates to a primer erasing liquid, which can be used to remove residual adhesives such as stickers, sticky notes, double-sided adhesives and the like in advertisements. Background technique [0002] With the continuous advancement of modern technology, products such as self-adhesive, sticky notes, and double-sided adhesive tape have been recognized by the general public, and can be seen everywhere on large and small appliances in life. The use and printing of self-adhesive is a process in which the ink and other substances in it pass through the printing plate with a certain pressure and then applied to the printed material containing the adhesive surface. It is usually widely used in many aspects such as leather goods, stationery, digital supplies, motor vehicle decorations, and handicrafts. But self-adhesive printing technology is also a double-edged sword. While it brings great convenience to our usual production and life, it is also...
