Problems solved by technology

During the electroforming process, after the nickel plate formed on the glass surface is separated from the glass, a large amount of impurities such as photoresist and silver will remain on the surface of the pit and the table, which will cause the bit error of the metal master to increase, exceeding the standard, and the appearance At the same time, during the use and transfer of the metal master, the metal master will be stained with dust, fingerprints, oil stains and other pollutants, which will also cause the metal master to exceed the standard in error codes and poor appearance

Embodiment 1

[0011] A kind of surface cleaning solution preparation of a metal mother disk is as follows in parts by weight: 1 part of mixed phosphate, 1 part of sulfamic acid, 1 part of wetting agent, 10 parts of sodium hydroxide, and 200 parts of deionized water; mix the above raw materials, adjust The pH is 11-12, and the temperature is kept at 45-55° C. to obtain a solution for cleaning the surface of the metal master disc.

[0012] The mixed phosphate is a neutral standard buffer solution with a pH of 6.86, containing Na 2 HPO 4 and KH 2 PO 4 .

[0013] The wetting agent is an anionic surfactant alkyl sulfate.

[0014] NaOH keeps the pH value of the solution at about 12; the heater keeps the temperature of the solution at 45-55°C; the solution circulates in the tank, and a filter is added to capture the pollutants washed out.

Embodiment 2

[0016] A kind of solution preparation for cleaning the surface of a metal master disk is as follows in parts by weight: 2 parts of mixed phosphate, 1.5 parts of sulfamic acid, 3 parts of wetting agent, 12 parts of sodium hydroxide, and 150 parts of deionized water; the above raw materials are mixed, adjusted pH to 12, keeping the temperature at 50° C. to obtain a solution for cleaning the surface of the metal master disk.

[0017] The mixed phosphate is a neutral standard buffer solution with a pH of 6.86, containing Na 2 HPO 4 and KH 2 PO 4 .

[0018] The wetting agent is an anionic surfactant sulfonate.

Embodiment 3

[0020] A kind of solution preparation for cleaning the surface of a metal master disk is as follows in parts by weight: 1.5 parts of mixed phosphate, 1.2 parts of sulfamic acid, 1 part of wetting agent, 11 parts of sodium hydroxide, and 180 parts of deionized water; the above-mentioned raw materials are mixed, adjusted pH to 12, keeping the temperature at 50° C. to obtain a solution for cleaning the surface of the metal master disk.

[0021] The mixed phosphate is a neutral standard buffer solution with a pH of 6.86, containing Na 2 HPO 4 and KH 2 PO 4 .

[0022] The wetting agent is anionic surfactant fatty acid.

[0023] Currently on the market, there are mainly two cleaning agents specially used for optical disk production, ISOPREP and StamperPrep. The cost of the cleaning solution for the surface of the metal master disk prepared in Examples 1-3 of the present invention is only equivalent to one-tenth of these two cleaning agents. , low price, simple and convenient co...

Abstract

The invention relates to a preparation method of a cleaning solution for the surface of a metal master disc, belonging to the technical field of cleaning agents. It includes deionized water, mixed phosphate, sulfamic acid, wetting agent and sodium hydroxide, which are mixed to obtain a cleaning solution for the surface of the metal master disk. The cleaning solution provided by the invention has less environmental pollution and simple waste water treatment. This formula solution has strong solubility, can absorb grease, fingerprints, dust, etc. on the metal master disc, and can also effectively remove the photoresist on the master disc.

Description

[0001] The invention relates to a preparation method of a cleaning solution for the surface of a metal master disc, belonging to the technical field of cleaning agents. Background technique [0002] The metal master disc used in the optical disc production process is made by uniformly coating photoresist on the optical glass, recording on the photoresist coating with a laser, developing the recording pits with a developer, and then Its surface is sputtered with a layer of silver. During the electroforming process, after the nickel plate formed on the glass surface is separated from the glass, a large amount of impurities such as photoresist and silver will remain on the surface of the pit and the table, which will cause the bit error of the metal master to increase, exceeding the standard, and the appearance At the same time, during the use and transfer process of the metal master, the metal master will be stained with dust, fingerprints, oil stains and other pollutants, which...
