Embodiment 1

[0027] First weigh 0.8 g of paraffin and add it to a round bottom flask, then weigh 65.8 g of dichloromethane and add it to the flask, stir at room temperature to dissolve the paraffin. Then 7.5 grams of xylene, 3.4 grams of methanol, 15.0 grams of formic acid, 1.5 grams of sodium benzoate, 3.0 grams of Tween 80 and 3.0 grams of Span 80 were added in sequence. Stir evenly at room temperature until the solid matter dissolves to obtain a degumming solution.

[0028] Apply the above-mentioned degumming solution evenly on the stainless steel surface with a protective film. After 16 minutes, the protective film will foam and wrinkle and fall off.

Embodiment 2

[0030] First weigh 1.0 g of paraffin and add it to a round bottom flask, then weigh 78.6 g of dichloromethane and add it to the flask, stir at room temperature to dissolve the paraffin. Then add 5.0 grams of xylene, 4.0 grams of ethanol, 10.0 grams of formic acid, 0.8 grams of urea, 1.2 grams of benzotriazole, 3.0 grams of Tween 80 and 3.0 grams of Span 80. Stir evenly at room temperature until the solid matter dissolves to obtain a degumming solution.

[0031] Apply the above-mentioned degumming solution evenly on the stainless steel surface with a protective film, and the protective film will foam and wrinkle and fall off after 15 minutes.

Embodiment 3

[0033] First weigh 1.2 grams of paraffin and add it to a round bottom flask, then weigh 104.3 grams of dichloromethane and add it to the flask, stir at room temperature to dissolve the paraffin. Then add 4.0 grams of ethanol, 10.2 grams of formic acid, 5.0 grams of turpentine, 1.1 grams of urea, 1.5 grams of benzotriazole, 1.5 grams of sodium dodecylbenzenesulfonate, 3.0 grams of Tween 80 and 3.0 grams of Span 80. Stir evenly at room temperature until the solid matter dissolves to obtain a degumming solution.

[0034] Apply the above-mentioned degumming solution evenly on the stainless steel surface with a protective film. After 12 minutes, the protective film will foam and wrinkle and fall off.

Abstract

A stainless steel adhesive remover composition of the present invention is prepared from a main solvent, a cosolvent, a penetrating agent, a surfactant, a corrosion inhibitor and a volatilization inhibitor. It is mainly used to remove all kinds of residual glue and its protective film on the surface of stainless steel, especially suitable for the removal of protective film and adhesive paper that have become brittle due to long-term light oxidation and aging. It has the following advantages: 1. The glue removal speed is fast and the effect is good. The hard-to-tear protective film can be softened, foamed and peeled off within 20 minutes. 2. No corrosion to stainless steel metal materials. 3. The residue is easy to wash with water. The preparation method of the stainless steel adhesive remover of the present invention is as follows: adding a certain amount of solvent in proportion to a container, and stirring evenly at a certain temperature.

Description

technical field [0001] The invention belongs to the field of glue removers, and in particular relates to a glue remover capable of removing protective films and residual glue on stainless steel surfaces and a preparation method thereof. Background technique [0002] Stainless steel has the characteristics of corrosion resistance, beautiful appearance, and good processing performance, and is widely used in industries such as industry and furniture decoration. In order to protect the bright surface of stainless steel and prevent surface defects such as dirt, scratches and scratches during handling, storage, molding and assembly, it is necessary to stick a layer of polyethylene protective film on the surface. The protective film is generally formed by coating a layer of adhesive on the surface of the polyethylene film. There are many types of adhesives, such as rubber type, acrylic type and so on. Mainly play the role of bonding stainless steel surface and polyethylene protec...
