Embodiment 1

[0039] Table 1 Glue remover formulation and process conditions

[0040]

[0041] Preparation method: weigh the main solvent according to the above formula and put it into a container, and then weigh the activator, corrosion inhibitor, volatilization inhibitor, emulsifier and thickener of the formula and add them to the main solvent separately and stir at the same time The finished product is obtained uniformly.

[0042] When using, brush the adhesive remover evenly on the surface of the sign with the adhesive layer at room temperature, with a thickness of 1mm, keep it for 20 minutes, wipe off the swollen adhesive layer, and then rinse it with water.

[0043] Test results: The glue removal rate on the surface of the substrate is 95%, and the surface of the metal substrate does not have any changes such as corrosion.

[0044]

Embodiment 2

[0046] Table 2 Glue remover formulation and process conditions

[0047]

[0048] Preparation method: weigh the main solvent according to the above formula and put it into a container, and then weigh the activator, corrosion inhibitor, volatilization inhibitor, emulsifier and thickener of the formula and add them to the main solvent separately and stir at the same time The finished product is obtained uniformly.

[0049] When using, brush the adhesive remover evenly on the surface of the sign with the adhesive layer at room temperature, with a thickness of 2mm, keep it for 25 minutes, wipe off the swollen adhesive layer, and then rinse it with water.

[0050] Test results: The glue removal rate on the surface of the substrate is 98%, and the surface of the metal substrate does not have any changes such as corrosion.

[0051]

Embodiment 3

[0053] Table 3 Glue remover formulation and process conditions

[0054]

[0055] Preparation method: weigh the main solvent according to the above formula and put it into a container, and then weigh the activator, corrosion inhibitor, volatilization inhibitor, emulsifier and thickener of the formula and add them to the main solvent separately and stir at the same time The finished product is obtained uniformly.

[0056] When in use, evenly brush the adhesive remover on the surface of the sign with the adhesive layer at room temperature, with a thickness of 3mm, keep it for 30 minutes, wipe off the swollen adhesive layer, and then rinse it with water.

[0057] Test results: The glue removal rate on the surface of the substrate is 100%, and there is no corrosion and other changes on the surface of the metal substrate.

Abstract

The invention discloses a degumming agent and a preparation method and application of the degumming agent. The degumming agent mainly contains the following ingredients in percentage by weight: 40%-60% of main solvent, 1.5%-3% of penetrant, 6%-10% of activating agent, 0.1%-0.3% of corrosion inhibitor, 5%-15% of thickening agent, 5%-10% of emulsifier, 10%-15% of volatilization inhibitor and the balance of water, wherein the main solvent is one or a mixture of several of methyl carbonate, ethyl-3-ethoxy propionate, dibasic ester, alkoxy alcohol, alcohol amine or benzoic alcohol. The degumming agent is simple in using method, is free from being heated and can be used at normal temperature by either brushing or spraying, and the time for washing is short, so that the production efficiency can be greatly increased.

Description

technical field [0001] The invention relates to the field of polymer solvent materials, in particular to a glue remover and its preparation method and application, in particular to a glue remover for removing high temperature resistant glue on the metal surface. Background technique [0002] In recent years, with the continuous increase of high-grade highways in our country, the driving speed of vehicles has continued to increase, and accidents such as vehicle rear-end collisions or rollovers at night and other low-visibility conditions have occurred from time to time. In order to effectively reduce the occurrence of such accidents and reduce the severity of accident consequences. It is urgent to modify or improve the main technical parameters such as the color, size specification, retroreflection coefficient and bonding force of the reflective material of the road sign and the basic requirements of the sign. This requires updating and replacing the original signboards. If ...
