Detailed Description
In order to make the technical problems, technical solutions and advantageous effects solved by the present invention more apparent, the present invention is further described in detail below with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
An embodiment of the invention provides an ink fading powder, which comprises the following components in parts by weight: 28-42 parts of surfactant, 20-36 parts of dibutyl maleate, 18-30 parts of pH regulator, 3-6 parts of activating agent and 7-11 parts of composite additive.
In the invention, defective products can appear in the process of processing optical glass into finished products and semi-finished products, in the process of repairing the defective products, deplating, ink removing and ultrasonic cleaning are required to be carried out in sequence, the conventional deplating process and formula are adopted during deplating, the ink mainly comprises pigments and connecting materials, wherein the pigments mainly comprise pigments and dyes, and the connecting materials play a role of a medium for dispersing the pigments and auxiliary materials and generally comprise a small amount of organic polymer components such as natural resin, synthetic resin, cellulose, rubber derivatives and the like. The auxiliary materials mainly comprise a filling agent, a diluting agent, an anti-skinning agent, an anti-offset agent, a slip agent and the like. Wherein the filler is mainly inorganic substances such as talcum powder and calcium carbonate, the diluent is mainly oligomeric linseed oil, mineral oil and the like, the main components of the anti-skinning agent are organic reducing agent and organic antioxidant, the anti-reprinting agent is most commonly corn starch, and the slip agent is microcrystalline wax, synthetic wax and the like.
In the ink fading powder disclosed by the embodiment of the invention, the surfactant, the dibutyl maleate, the stripping agent, the activating agent and the composite additive are compounded into the ink fading powder according to a reasonable proportion, so that the surfactant can reduce the surface tension when the ink fading is carried out, and the ink fading powder has good balance and dynamic surface tension performance, so that the surface of the base material has excellent wettability and can soften the ink. The stripping agent is strong alkali and has a stripping effect on the ink, and the dibutyl maleate is cooperated with the surfactant, so that the surfactant is migrated to an ink/substrate interface to provide wettability, the stripping force on the ink is enhanced, the ink is stripped from the surface of the optical glass, and no ink residue exists after ink stripping.
In addition, the activating agent can promote the synergistic effect of the surfactant and the dibutyl maleate, and the compound additive has a certain corrosion inhibition effect, so that no corrosion inhibitor is required to be added into the ink fading powder. The invention does not corrode the surface of the optical glass, can perform tempering, silk-screen printing and film coating again after ink fading is clean to obtain a finished product, reduces the loss caused by defective products, and improves the production benefit.
In one embodiment, preferably, the surfactant is 32-38 parts, the dibutyl maleate is 25-32 parts, the peeling agent is 20-26 parts, the activating agent is 3-5 parts, and the composite additive is 8-10 parts.

Comparative example 1
The toner fading agent comprises the following components in parts by weight: 35 parts of citric acid fatty glyceride, 24 parts of sodium hydroxide, 4 parts of sodium phosphate and 9 parts of sodium glutamate. The application method of the ink fading powder is the same as that in example 1.
Comparative example 2
The toner fading agent comprises the following components in parts by weight: 28 parts of dibutyl maleate, 24 parts of sodium hydroxide, 4 parts of sodium phosphate and 9 parts of sodium glutamate. The application method of the ink fading powder is the same as that in example 1.
Comparative example 3
The toner fading agent comprises the following components in parts by weight: 28 parts of dibutyl maleate, 35 parts of citric acid fatty glyceride, 4 parts of sodium phosphate and 9 parts of sodium glutamate. The application method of the ink fading powder is the same as that in example 1.
Comparative example 4
The toner fading agent comprises the following components in parts by weight: 28 parts of dibutyl maleate, 35 parts of citric acid fatty glyceride, 24 parts of sodium hydroxide and 9 parts of sodium glutamate. The application method of the ink fading powder is the same as that in example 1.
Comparative example 5
The toner fading agent comprises the following components in parts by weight: 28 parts of dibutyl maleate, 35 parts of citric acid fatty glyceride, 24 parts of sodium hydroxide and 4 parts of sodium phosphate. The application method of the ink fading powder is the same as that in example 1.
By using the optical lenses obtained in the embodiments 1 to 13 to perform the ink removing treatment on the defective optical lens, the optical lens has a good ink removing effect, and the optical lens after ink removing has no ink residue on the surface and no corrosion, and does not cause secondary damage to the optical glass and chemical corrosion.
When the optical lens is subjected to ink fading, the optical lens after the ink fading powder in the embodiment 2 to the embodiment 9 is used has no ink residue and no corrosion, but the cleaning powder in the embodiment 1, the embodiment 10 to the embodiment 13 is an optimal embodiment when the cleaning powder is compared with the embodiment 1, wherein the cleaning powder has the advantages of optimal ink fading effect, high ink clearing speed, good ink fading effect and high efficiency.
By comparing example 1 with comparative example 1 and comparative example 2, it is found that the synergistic effect of dibutyl maleate and the surfactant cannot be completed in comparative example 1 and comparative example 2, the migration capability of the surfactant to an ink/substrate interface is reduced, the stripping effect of the ink is influenced, and the ink on the surface of the optical glass has residue after stripping.
It was found by comparing example 1 with comparative example 3 that in comparative example 3, the peeling of the ink could not be completed without the peeling agent.
Comparison of example 1 with comparative example 4 shows that the absence of the activator in comparative example 4 reduces the synergistic effect of the surfactant and dibutyl maleate, resulting in slower ink peeling with slight residue.
Compared with the comparative example 5, the comparative example 5 does not contain the composite additive, so that the stripping solution does not have a corrosion inhibition effect, and after stripping is finished, the surface of the optical glass has chemical corrosion and an atomization phenomenon.
In the embodiment 1 of the invention, the surface active agent, the dibutyl maleate, the stripping agent, the activating agent and the composite additive are compounded into the ink fading powder according to a reasonable proportion, so that the ink drops from the surface of the optical glass, no ink residue exists after the ink fading, the surface of the optical glass is not corroded, and the stripping effect is good.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
