Abstract
The present invention relates to a production method of deep-etched glass capable of changing patterns with the change of visual angle. The method comprises: cleaning and airing one side of transparent flat glass after the side is sealed by a protective film; printing and airing patterns designed in advance on one side of the flat glass by the silk screen with anticorrosion printing ink, wherein the side of the flat glass is not provided with the protective film; putting the flat glass printed with the patterns into an etching liquid pool to be etched; cleaning etched glass to remove the protective film; printing patterns the same as the patterns of the etched side on the glass side not etched by the silk screen after the etched side of the glass is covered with the protective film, and airing formed printing ink patterns aligned with concave patterns on the etched side; putting aired glass in an emulsion groove for being emulsified, and taking out, cleaning and airing the glass; putting aired glass into a tank containing sodium hydroxide solution for being soaked, taking out and cleanly cleaning the glass to remove the protective film of the etched side, and then cleaning and airing the glass; washing out the printing ink on the etched side of the glass to form a finished product. The present invention has the advantages of glittering and translucent carving and strong three-dimension effect. The patterns change with the change of visual angles.
Description
Technical field:
The present invention is relevant with the production method of etching glass, and the production method of the deep etching glass of special and energy changing patterns along with visual angles is relevant.
Background technology:
The patent No. 02109830.1 provides a kind of production method of concave convered glass.This method is that the sheet glass that will clean up carries out carrying out silk screen printing with the pattern that designs in advance after the desktop emulsification, put into etching tank then and soak, put into the sodium hydro-fluoride groove again after cleaning after soaking and soak, clean once more, remove corrosion-resistanting ink, clean again, dry finished product.Hydrofluoric acid containing concentration height in its etching liquid, fluohydric acid content height in the waste liquid, environmental pollution is big, and the cost height disposes waste liquid.And male and fomale(M﹠F) on the concave convered glass of producing and frosting and with the one side on, so pattern can not change with visual angle change.
Summary of the invention:
The objective of the invention is provides a kind of glittering and translucent in order to overcome above deficiency, and stereoscopic sensation is strong, the production method of the deep etching glass of energy changing patterns along with visual angles.
The objective of the invention is to realize so real:
The production method of the deep etching glass of the present invention's energy changing patterns along with visual angles comprises the steps:
1), with protective membrane with the face closure on the clear plate glass and clean, dry;
2), on the one side of sheet glass unprotect film and dry, printing-ink adopts corrosion-resistanting ink with the designed with patterns silk screen printing;
3), etching was carried out 60～120 minutes in the sheet glass that is printed on pattern after will the drying pond of putting into etching liquid;
4), the glass after the etching is put into clean water basin soak the back take out clean and remove protective membrane on it after clean up again;
5), with above-mentioned 4) glass after the step process covers behind the etched surface at pattern that will be identical with the etched surface pattern on the etched surface not with protective membrane again and aims at pattern on the etched surface and silk screen printing on etched surface not, the ink logo that forms is aimed at the groove pattern on the etched surface, dries;
6), the glass after will drying is put into the groove emulsification 1～5 minute that fills emulsion, is taken out in the clean water basin and soaks, shifts out and dry;
7), the sheet glass after will drying is put into the pond that fills sodium hydroxide solution and was soaked 10～25 minutes, and taking-up cleans up, and removes to clean behind the protective membrane on the etched surface again and dries;
8), wash off clean up behind the printing-ink on the glass etching face finished product;
Etching liquid in the above-mentioned steps is 55% hydrofluoric acid 20～24% by weight percentage by weight percent concentration; weight percent concentration is 98% acid solution 20～31%; form with water 48～58%; wherein acid solution is nitric acid or sulfuric acid, and protective membrane can adopt the little glued membrane of polyethylene or other glass protection film.
Emulsion is made up of ammonium bifluoride 41～46%, sulfuric acid 17～26%, water 33～37% by weight percentage in the above-mentioned method, and emulsion makes whole space of a whole page printing opacity opaque, also can adopt other commercially available emulsion.
In the above-mentioned method with above-mentioned 1,2) printed pattern and air dried glass were put into the pre-etching of pre-etching liquid 60～120 minutes in the step.
Pre-etching liquid is that 55% hydrofluoric acid 10～15%, weight percent concentration are that 98% sulfuric acid 15～20%, water 70～75% are formed by weight percent concentration by weight percentage in the above-mentioned method.
Pre-etching liquid adopts the useless etching liquid of exhausted in the etching liquid pool in the above-mentioned method, reduces the hydrofluoric acid concentration in the etching liquid.
In the above-mentioned method with above-mentioned 1,6) put into to move to after the groove that fills polishing fluid is handled 15～25 minutes to shift out after clean water basin soak through the glass after the emulsification in the step and dry, polishing fluid is 55% hydrofluoric acid 5～10% by weight percentage by weight percent concentration, weight percent concentration is 98% sulfuric acid 10～15%, water 80～85% is formed, polishing fluid also can adopt exhausted waste liquid in the pre-etching liquid, further reduces the hydrofluoric acid concentration in the etching liquid.
Wash printing ink on the glass etching face off with steel wire lump and clear water in above-mentioned above-mentioned 1,8 steps.
Compare with the production method of existing concave convered glass, the present invention has following advantage:
1, adopt emulsification after the first etching, sheet glass one side screen printed pattern is carried out after the etching not screen printed pattern on the etched surface, make the ink logo of formation aim at groove pattern on the etched surface, stereoscopic sensation is strong, and is glittering and translucent, emission face also has and the identical transparent pattern of etched surface, change in pattern is not surveyed at the different visual angles place, has extremely strong visual impact and high ornamental, can be used for upholstery, furniture engineering etc.;
2, adopt pre-etching procedure, etching depth is deepened, make the glass stereoscopic sensation after the etching stronger, can handle the waste liquid in the etching liquid simultaneously, polishing fluid can adopt the waste liquid in the pre-etching liquid, make that the hydrofluoric acid degree of depth reduces greatly in the etching liquid, make the pollution of last waste liquid handle load reduction greatly, make the beautifulr matter of product penetrating again simultaneously, and be difficult for staining;
3, total etching time can be controlled in 120～240 minutes, can adopt steel wire lump to clean the printing ink of male and fomale(M﹠F), make between glass convex part and recessed part vertical surface to form than the big characteristics of the formed chamfer radius of other technology, it is smooth and easy to touch film, convenient for cleaning.
