Description

Light metal-imitative character-plate

The utility model relates to a kind of word board, and more particularly, the utility model relates to letter, numeral or the symbol that is fixed in the supporting, mark, famous brand or signboard, figure or sculpture.

Existing word board, as the decoration word board on hotel, factory, shop and other buildings shop front, non-ferrous metal commonly used such as brass etc. are made; with cold-working of brass sheet material or forge hot machine-shaping; local welding, again by after surfacing, polishing and even electroplating, coated protective coating again.The shortcoming of these copper word boards is:

1. the difficulty of processing and fabricating is big, to producer's technical requirement height, and complex process, production efficiency is low, and can produce serious noise in cold forming.

2. numerous word boards will expend the very considerable brass of quantity or other metal material.In copper resource very short today, this is a waste greatly really.

3. expense costliness, every square metre copper word board, its price is more than 400 yuan.

4. brass surfaces is turned black easily, although adopt surperficial coating process, also is difficult to prevent.

5. weight is big, brings difficulty for supporting or suspension.

Task of the present utility model is to provide a kind of easy to make, durable in use, cheap, imitative metal word board of lightweight that color and luster is various is made by nonmetallic materials.

In brief, the design's word board comprises Chinese character, numeral, outer literal or other symbol, and mark, famous brand, signboard, figure or sculpture are to be matrix by nonmetallic materials, and the resin-blocked layer, 700～5000 that 10～200 μ m are thick has been arranged on its surface successively

Thick metal film layer and transparent protective resin layer.Requirement according to word board drawing; foamed plastic (or timber or other light plastic) is processed into the matrix of word board; fill the thin layer filler in its surface; coat confining bed again; plate the skim metal level with vacuum evaporation, magnetron sputtering or electrochemical plating; coat which floor protective seam then, just make the design's the imitative metal word board of lightweight.

Fig. 1 is the fragmentary section views of this word board basic structure.Among the figure, the 1-matrix, the 2-filler, the 3-confining bed, 4-adds photosphere, 5-metal film layer, the transparent inner protective layer of 6-, the transparent external protection of 7-.

Below in conjunction with description of drawings the design's detailed content, but summary of the invention is not limited to description of drawings.

Referring to Fig. 1, the matrix 1 of this word board is made by foamed plastic or timber or other lightweight engineered plastics. Foamed plastic can adopt polyphenyl class, polyvinyl chloride (PVC) class, polyethylene or the low foaming of other plastics, middle foaming or the high-foaming plastic plate of commodity, wherein take low blown rigid plastic plate as best; Timber should be selected the timber of quality exquisiteness, preferably passes through in advance drying and processing; The ABS(acrylonitrile-butadiene-styrene copolymer), the AS(acrylonitritrile-styrene resin), the sheet material of the plastics such as PVC, modified polyphenyl alkene, polyethylene, and the sheet material of lucite also can be used as the design's matrix material. According to word board drawing requirement, foamed plastic or timber or plastic plate cutting are engraved as required shape, polish on the surface, makes the matrix 1 of word board. The outer surface of the 2 pairs of matrixes of filler that form with materials such as gypsum carries out the several times filling, to remedy lip-deep defective or pin hole. Then to whole Surfacecoating one deck or some layers of confining bed 3, closed material can be with commercially available epoxy glue, shellac or other resin, and the thickness visible surface fineness of confining bed 3 and deciding is generally in 10～200 mu m ranges. At coated the surface of confining bed 3 be coated with again the last layer resin and add photosphere 4, further adding optical surface, and make the surface harder. When coated confining bed 3 rear surfaces enough whens light, can no longer be coated with and be added with photosphere.

For the big word board of those versatilities, as general Office tag Chinese character of Arabic word, foreign letter and industrial and mining enterprises etc., then can adopt injection moulding, with plastics in bulk pressure injection go out the matrix 1 of word board, directly it is carried out the surface sealing and adds optical processing then, coat the confining bed 3 of cold coating and add photosphere 4.

The above-mentioned photosphere 4 that adds if subsequent technique is electrochemical plating, then should mix an amount of conductive agent in adding optical coating.

Adopt vacuum evaporation or sputtering method commonly used, perhaps electrochemical plating, plating a layer thickness on the surface of above-mentioned matrix 1 is 700 ～5000

The metal film layer 5 of aluminum or aluminum alloy, copper or aldary, again its surperficial coated one deck or which floor tens microns to the transparent resin coating of hundreds of micron thickness as interior external protection 6,7, just made imitative metal word board silver color or simulating golden colour.

If mix or contaminate the coloring agent of certain required color and luster on the inner protective layer 6, and then coated contains the transparent external protection 7 of anti ultraviolet agent, then can be made into the imitative metal word board of required color and luster, as 24K gold, 18K gold, bronze-colored, Borland look word board.

This word board by means of multiple common process making; it is characterized in that: it contains the matrix 1 that a foamed plastic or timber or other lightweight engineered plastics are made; a confining bed 3 or add 4, one metal film layers 5 of photosphere and the protective finish 6,7 of a transparent or colored transparent.

The design's word board with existing copper word board relatively has the following advantages:

1. because matrix 1 usefulness nonmetallic materials are made, therefore save the very considerable copper material of quantity.

2. because matrix material is foamed plastic or other easy plastics or timber of processing, therefore not only processing and fabricating is very convenient, and can make the word board of arbitrary shape and size, as the Chinese character of various fonts, outer literal, embossment, pattern or the like.

3. in light weight, and be fixed on easily in any supporting.

4. with low cost, only be about 20% of copper word board.

5. color and luster is numerous in variety, can make the word board of any color and luster, and copper word board color and luster is single.

6. because the metallic diaphragm of this word board is a lining under the clean atmosphere of vacuum, and metal targets (mother metal) can carry out oxidation resistant optimization proportioning in advance, so the performance of the anti-variable color of its oxidation and corrosion is better than copper word board.
