Problems solved by technology

The test of CN1407033 found that the stripping solution compounded by oxidant and organic solvent can effectively remove the photosensitive adhesive, but its composition contains a large amount of organic solvents such as alicyclic hydrocarbon ketones, phenols, aliphatic mono(multi) Hydrocarbons, polyhalogenated hydrocarbons and pyrrolidones are volatile during use and cause potential harm to human health. The formula is in a solution state, which will undoubtedly cause inconvenience in transportation and increase production costs, reducing the economic benefits of the enterprise

Embodiment 1

[0033] The release agent is mainly made of the following raw materials in parts by weight:

[0034]

[0035] Wherein, surfactant adopts sodium dodecylbenzenesulfonate.

[0036] The oxidizing agent is sodium hypochlorite.

[0037] The acidic compound is citric acid.

[0038] The chelating agent adopts sodium hexametaphosphate.

[0039] The peroxide is ammonium persulfate.

[0040] Inorganic salt adopts potassium chloride.

[0041] The preparation method of the release agent is to take each raw material according to the above-mentioned quality and mix them at room temperature.

[0042] When the release agent is used, the above-mentioned release agent and water are made into an aqueous solution in a mass ratio of 1:50, and a small amount of release solution is dipped with a release water brush during use, and applied on both sides of the screen Evenly, after standing for 10 minutes, the photosensitive film dissolves and falls off, and then rinses off with clean water or a...

Embodiment 2

[0044] The release agent is mainly made of the following raw materials in parts by weight:

[0045]

[0046] Wherein, surfactant adopts coconut oil monoethanolamide.

[0047] The oxidizing agent is one of sodium dichromate.

[0048] The acidic compound is tartaric acid.

[0049] Chelating agent adopts stearyl citrate.

[0050]The peroxide is potassium persulfate.

[0051] Inorganic salt adopts sodium bicarbonate.

[0052] The preparation method of the release agent is to take each raw material according to the above-mentioned quality and mix them at room temperature.

[0053] When in use, the prepared above-mentioned release agent and water are formulated into an aqueous solution in a ratio of 1:70 (mass ratio), which can effectively remove the screen photosensitive glue. Under the synergistic effect of surfactants, the penetration of persulfate on the photosensitive adhesive can be strengthened, and the detachment of the photosensitive adhesive can be accelerated.

Embodiment 3

[0055] The release agent is mainly composed of the following raw materials in parts by weight:

[0056]

[0057]

[0058] Wherein, surfactant adopts lauryltrimethylammonium bromide.

[0059] The oxidizing agent is sodium perchlorate.

[0060] The acidic compound uses sodium bisulfate.

[0061] The chelating agent adopts amino trimethylene phosphonic acid.

[0062] The peroxide is ammonium persulfate.

[0063] Inorganic salt adopts sodium chloride.

[0064] The preparation method of the release agent is to take each raw material according to the above-mentioned quality and mix them at room temperature.

[0065] When in use, the prepared above-mentioned release agent and water are formulated into an aqueous solution at a mass ratio of 1:80. Under the catalysis of acidic substances, the oxidizing agent can quickly oxidize the photosensitive adhesive to completely remove the residual ink and ink on the mesh. Sealing slurry.

Abstract

The invention discloses a release agent for removing a diazo photoresist of a screen printing plate and a use method thereof. The release agent is mainly prepared from the following raw materials in parts by weight: 2-30 parts of surfactant, 4-50 parts of oxidant, 1-35 parts of acidic compound, 2-30 parts of chelating agent, 7-40 parts of peroxide and 5-35 parts of inorganic salt. The release agent is powder which can effectively remove the diazo photoresist on the screen printing plate. The release agent is easy to wash, strong in releasing effect, safe and environment-friendly, harmless to a human body and low in cost. The invention further discloses a use method of the release agent.

Description

technical field [0001] The invention belongs to the technical field of screen printing materials, and in particular relates to a release agent for removing a screen printing screen plate diazo photosensitive adhesive and a use method thereof. Background technique [0002] At present, the screen materials used for screen printing are mainly polyester screens and nylon screens. Because polyester screen has the characteristics of good dimensional stability, high tensile strength, and good resistance to resistance, the usage rate has accounted for more than 90% in the screen printing of ordinary products. The plate-making material of the screen screen plate is mainly a composite diazo resin photosensitive adhesive screen plate. The diazo photosensitive adhesive sold on the market is usually based on cross-linked emulsification of polymers such as polyvinyl alcohol and polyvinyl acetate. The screen template is to use photosensitive glue to make text and graphics for printing on ...
