Abstract
A metal form is composed of a metal form baseplate whose surface has circular grain pattern, and has a passivated film formed on the surface of metal substrate by electrolysis. During electrolysis, the antioxidizing agent solution, bichromate solution, degreasing agent, or sodium hydroxide solution can be used.
Description
Technical field
The invention relates to a kind of metal matrix, particularly a kind of large size (area 2480cm that is used in
2More than) metal matrix on the rear-projection element.
Background technology
When making light rear-projection element or CD, be the metal pattern substrate of protection master, the dealer can utilize the metal pattern substrate of master to be copied into another master mold version usually or the submodule version is applied.
For undersized disc plate is made; because its mould substrate area is less, and its inter-ridge distance is thinner, so the dealer is carrying out the mould substrate when duplicating; normally can on the metal pattern substrate, form one, and then on passive film, form an electrolytic coating with plating mode by the formed passive film of metal.Afterwards, again according to the principle that contains the electrical potential energy difference between passive film and metal pattern base version and the electrolytic coating, make metal pattern base version and the electrolytic coating can delamination, and then the masterplate that hits pay dirk turn over system.For example shown in Figure 1, it is to electroplate one deck chromium metal pattern 32 with a strong acid solution (as sulfuric acid) on the surface of metal pattern base version 31, make metal pattern base version 31 subsequently metal matrix 3 turn in the system processing procedure can with electrolytic coating 33 delamination.
Though aforesaid way can be used in small sized metallic mould substrate; but if when being used in the metal pattern substrate of large size light rear-projection element, then have problem, its reason is that the area of metal pattern substrate of light rear-projection element is much larger than CD metal pattern substrate; and the cost of chromium metal is higher, and is unfavorable for using.In addition, the lines size of the metal pattern substrate of light rear-projection element is big far beyond CD metal pattern substrate, if make the chromium metal that the problem of the unfavorable demoulding then be arranged.Moreover its pH-value of employed sulfuric acid is a strong acid highly toxic substance below 2 during owing to the passivation of CD metal pattern substrate, and safe misgivings are arranged during operation.So as how low-cost, and the metal matrix of convenient reproduction light rear-projection element is an important topic in fact.
Summary of the invention
At the problems referred to above, the purpose of this invention is to provide a kind of with low cost and easy metal matrix of the demoulding.
For reaching above-mentioned purpose, the invention provides a kind of metal matrix, comprise a metal pattern base version and a passive film.The surface of metal pattern base version is formed with a circular arc lines, is formed with on the surface of circular arc lines and passive film is formed at metal pattern base version with electrolysis mode, can use antioxidant solution or dichromate solution or grease-removing agent or sodium hydroxide solution when carrying out electrolysis.
The invention provides a kind of metal matrix, wherein comprise a passive film, make metal matrix demoulding in duplicating easy.Compare with conventional art, a kind of metal matrix of the present invention need not use strong acid, so safe when operation; Also do not need the electrodeposited chromium metal, can reduce the cost on the cost, also can be applicable to 30 inches (76.2cm) (2480cm
2) system of the turning over processing procedure of above metal matrix version; Can not change the lip-deep lines of metal pattern base version again, can reduce the failure in the duplicating.
