Embodiment 1

[0028] Embodiment 1: The present embodiment provides a kind of low-scratch glass paint remover, and its each component and mass percentage are as follows: deionized water 45%; Sodium potassium hydroxide 15%; EDTA-4Na 2%; Benzyl alcohol 6%; diethylene glycol ethyl ether 8%; tetrahydrofurfuryl alcohol 10%; ethylene glycol 4%; triethanolamine 10%.

[0029] Take the preparation of 100kg low-scratch glass paint remover as an example: Weigh 46kg of deionized water (including 1kg of evaporation water consumption, the same below), turn on the agitator (60-80 rpm); Potassium 15kg, pour into the mixing bucket, stir; weigh 2kg of EDTA-4Na, pour into the mixing bucket, stir; when the temperature of the solution in the bucket drops below 40°C, weigh 6kg of benzyl alcohol and diethylene glycol ethyl ether in sequence 8kg, 10kg of tetrahydrofurfuryl alcohol, 4kg of ethylene glycol, and 10kg of triethanolamine are poured into the barrel, stirred evenly and then filled to obtain a low-scratch ...

Embodiment 2

[0030] Embodiment 2, a kind of low-scratch glass paint remover and its preparation method provided by this implementation, it is basically the same as Example 1, the difference is: the components and mass percentages of the low-scratch glass paint remover are as follows: Deionized water 42%; sodium potassium hydroxide 15%; EDTA-4Na 3%; ethylene glycol phenyl ether 6%; diethylene glycol butyl ether 6%; tetrahydrofurfuryl alcohol 12%; electrolytic water 6%; monoethanolamine 10 %.

Embodiment 3

[0031] Embodiment 3, a kind of low-scratch glass paint remover and its preparation method provided by this implementation, it is basically the same as Example 1, the difference is: the components and mass percentages of the low-scratch glass paint remover are as follows: Deionized water 42%; sodium potassium hydroxide 15%; EDTA-4Na 3%; ethylene glycol phenyl ether 6%; diethylene glycol butyl ether 6%; tetrahydrofurfuryl alcohol 12%; electrolytic water 6%; monoethanolamine 10 %.

Abstract

The invention discloses a low-scratch glass paint remover and a preparation method thereof. The low-scratch glass paint remover comprises the following components in percentage by mass: 28%-49% of deionized water, 15%-20% of an inorganic base, 2%-4% of a complexing agent, 10%-12% of an organic base, 6%-8% of an organic solvent a, 6%-8% of an organic solvent b, 8%-12% of an organic solvent c and 4%-8% of an organic solvent d. According to the invention, the ratio of water to an inorganic base in a formula is reasonably controlled, so that the corrosion of glass is reduced to the greatest extenton the premise of ensuring the paint removal speed, the glass surface subjected to paint removal has excellent removal capability on silk-screen printing ink, the corrosion phenomena of bluing, fogging and the like on the glass surface are avoided, the scratch rate is controlled to be 5% or below, and the glass product quality is effectively ensured; and the method provided by the invention is simple in preparation process, easy to realize and high in production efficiency, and can be used for quickly and efficiently preparing the low-scratch glass paint remover with excellent comprehensive performance.

Description

technical field [0001] The invention belongs to the technical field of paint removers, and in particular relates to a low-scratch glass paint remover and a preparation method thereof, which can be widely used in removing and cleaning glass screen printing inks. Background technique [0002] Screen printing ink (frame) is an essential basic process in the production and deep processing of mobile phone cover and touch screen manufacturers. Due to various reasons, there are a certain number of defective products that need to be reworked. This requires removing the ink and re-screening the ink. After the ink is removed, it is required that the glass surface should not have bluish, foggy, scratched and other undesirable phenomena. Otherwise, the glass needs to be re-polished, which will increase the production cost and reduce the production efficiency. At present, most of the paint removers sold on the market have the defect of high glass scratch rate (generally up to 30%). I...
