Embodiment approach 1

[0014] Formula: 10% benzyl alcohol, 2% surfactant, 2% glycerin, 3% organic additives, and the balance of water, 100% in total. The surfactant can be sodium dodecylsulfonate, Tween-40, Tween-80. The organic auxiliary agent can be ethanol, acetone, ethyl acetate, ethyl formate, n-butanol, methyl ethyl ketone, propylene glycol methyl ether, dipropylene glycol methyl ether or a mixture of more than one.

[0015] Preparation method: Dissolve the surfactant in water, stir to dissolve, then add the organic matter into it, stir quickly and evenly to obtain a uniform and stable liquid, and the solution is transparent.

[0016] Scrubbing method: use a rag or cotton ball dipped in the cleaning agent to scrub.

[0017] Cleaning effect: The modified formula can clean the pressure-sensitive adhesive residue on the surface of glass, ceramics, concrete, etc., and the cleaning time is about 1 minute.

Embodiment approach 2

[0019] Formula: 15% benzyl alcohol, 2% surfactant, 3% glycerol, 5% organic auxiliary agent, and the balance of water, 100% in total. The surfactant can be sodium dodecylsulfonate, Tween-40, Tween-80. The organic auxiliary agent can be ethanol, acetone, ethyl acetate, ethyl formate, n-butanol, methyl ethyl ketone, propylene glycol methyl ether, dipropylene glycol methyl ether or a mixture of more than one.

[0020] Preparation method: Dissolve the surfactant in water, stir to dissolve, then add the organic matter into it, stir quickly and evenly to obtain a uniform and stable liquid, and the solution is transparent.

[0021] Scrubbing method: use a rag or cotton ball dipped in the cleaning agent to scrub.

[0022] Cleaning effect: The modified formula can remove pressure-sensitive adhesive residues on the surface of polar polymer materials such as PVC, and the cleaning time is about 1 minute.

Embodiment approach 3

[0024] Formula: 20% benzyl alcohol, 3% surfactant, 3% glycerol, 10% organic auxiliary agent, and the balance of water, 100% in total. The surfactant can be sodium lauryl sulfonate, Tween-40, Tween-80. The organic auxiliary agent can be ethanol, acetone, ethyl acetate, ethyl formate, n-butanol, methyl ethyl ketone, propylene glycol methyl ether, dipropylene glycol methyl ether or a mixture of more than one.

[0025] Preparation method: Dissolve the surfactant in water, stir to dissolve, then add the organic matter into it, stir quickly and evenly to obtain a uniform and stable liquid, and the solution is transparent.

[0026] Scrubbing method: use a rag or cotton ball dipped in the cleaning agent to scrub.

[0027] Cleaning effect: The modified formula can clean the pressure-sensitive adhesive residue on the surface of stainless steel, aluminum alloy, etc., and the cleaning time is about 1 minute.

Abstract

The invention discloses a water-based cleaning agent of pressure-sensitive adhesive residues, which is characterized by the following: it is composed by 10-25% benzoic alcohol, 1-5% surfactant, 1-5% glyceryl alcohol, 0-10% organic aids and water. This invention possesses merits of low volatility, strong penetrability, safety, fast cleaning speed, low volatility and without toxic.

Description

technical field [0001] The invention relates to the field of chemical cleaning agents, in particular to a water-based cleaning agent for pressure-sensitive adhesive residues. Background technique [0002] Pressure-sensitive adhesives, commonly known as self-adhesives, are generally composed of a main polymer, a tackifier, a softener, and an anti-aging agent. According to the base material, it can be divided into natural rubber type, synthetic rubber type, thermoplastic elastomer type, acrylate type and silicone pressure sensitive adhesive. At present, the main polymers of pressure-sensitive adhesives widely used are generally synthetic rubber and polyacrylate. In comparison, polyacrylate pressure-sensitive adhesives are more widely used. [0003] Pressure-sensitive adhesive has brought great convenience to people's daily life because of its strong cohesive force, convenient use and quickness. However, it has also brought a lot of troubles. Big difficulty. At present, peop...
