The technology of a kind of gilding/silver foil
Technical field
The present invention relates to the technology of a kind of gilding/silver foil, be meant that especially a kind of foliation is respond well, and can effectively prevent gilding/silver foil technology of oil paint cracking.
Background technology
The production of gold/silver foil is in the history in existing more than 2,000 year of China, and it is widely used in historic gardens building, imperial palace, board etc., has good decoration effect.
CN2607409Y discloses a kind of ornament materials of gilding, and it is made up of sheet material, prime coat, rubberizing water layer, metal foil layer, patterned layer and protective layer successively.Because the existence of expanding with heat and contract with cold, this ornament materials in use are easy to the problem that produces cracking, bubble and come unstuck, have a strong impact on its service life.In addition, prior art is when spray paint and glue, and a whole often brushing is easy to occur the phenomenon of overweight coating, and then causes waste.
Summary of the invention
The invention provides the technology of a kind of gilding/silver foil, its purpose is to overcome the above-mentioned defective that prior art exists.
Technical scheme of the present invention is following:
The technology of a kind of gilding/silver foil, it may further comprise the steps: a) treating foliation face primer spray, waiting to do the no particle in back light weight sand to surface; B) on priming paint, spray glue, gild again/silver foil after waiting to do; C) after foliation is accomplished, spray paint; Before step a, need treating to apply one deck gold/silver oil on the foliation face earlier; Between step b and c, also need spray one time ethene priming paint at least; After finish paint among the step c is waited to do, carry out dehumidifier and handle, treat that dehumidifier is accomplished after, under constant temperature, dry again and make finished product.
Further, need between said step b and the c through successively spraying three times ethene priming paint.
Further, the priming paint among the said step a is NC priming paint; Finish paint among the said step c is the NC finish paint.
Further, the temperature of said constant temperature is between 30-40 ℃.
As further improvement of the present invention, after step c and before the dehumidifier processing, need to apply one deck polish lacquer.
Further improve as of the present invention, the spraying method of said NC priming paint, glue, ethene priming paint, NC finish paint and polish lacquer all is in cross shape of the middle part of spraying face spray.
Can know by the above-mentioned description of this invention, compare, the invention has the advantages that with prior art:
1, of the present invention gilding/silver foil product dried processing through dehumidifier and constant temperature, and it the problem that ftractures, bubble and come unstuck in use can not occur, thereby has greatly prolonged service life.
2, through the spraying polish lacquer, can effectively strengthen gold/silver foil light effect.
3, the spraying method of NC priming paint, glue, ethene priming paint, NC finish paint and polish lacquer all is in cross shape of the middle part of spraying face spray; The advantage of this spraying method is; The automatic levelling of above-mentioned sprayed on material meeting; It not only can realize the evenly effect of spraying, and its thickness is thinner usually, thereby has avoided the waste of sprayed on material.
4, can avoid through coated with gold/silver-colored oil in advance gilding/problem of the blackout of revealing the exact details during silver foil takes place.
The specific embodiment
Embodiment one
The technology of a kind of gilding/silver foil, it may further comprise the steps: on the foliation face, apply one deck gold/silver oil in advance and form a gold medal/silver-colored oil reservoir, to prevent formally to gild/generation is revealed the exact details and turned black during silver foil problem; Then at gold/silver-colored oil reservoir middle part with cross that thickness is moderate of NC priming paint ejection, the NC priming paint of this crux can to around levelling and evenly covering to whole gold/silver-colored oil reservoir surface, wait to do the back with the extremely surperficial no particle of sand paper light weight sand; In the middle part of the NC prime coat, spray the cross that thickness is moderate with glue (being generally oiliness glue) then, the glue of this crux can be gilded/silver foil on its surface after waiting to do to levelling and the extremely whole NC prime coat of even covering are surperficial all around again; Follow and in the middle part of gold/silver foil surface, spray a cross with ethene priming paint, ethene priming paint can be used the sand paper light weight sand after waiting to do to levelling and even covering to whole gold/silver foil are surperficial all around; And then spray a cross at the middle part of ethene priming paint with the NC finish paint, the NC finish paint can to around levelling and evenly covering to whole ethene prime coat surface; After treating NC finish paint drying at last, carry out dehumidifier and handle (such as the air-conditioning dehumidifier), after dehumidifier is accomplished, under 30 ℃ of constant temperature, dry again and make finished product.
Gold in the above-mentioned steps/silver oil, NC priming paint, NC finish paint, ethene priming paint are all comparatively common in the prior art, repeat no more at this.
Embodiment two
The step of present embodiment and the foregoing description one is basic identical, and its main distinction is that the gold of present embodiment/successively spray on the silver foil surface has ethene priming paint three times; After the NC finish paint drying, need be at its surface sprinkling cruciformity ground polish lacquer, these polish lacquers can through the spraying polish lacquer, can effectively strengthen gold/silver foil light effect to levelling and even covering to whole NC top coat layer are surperficial all around; In addition, present embodiment dries under 40 ℃ of constant temperature.
Embodiment three
The step of present embodiment and the foregoing description two is basic identical, and its main distinction is that present embodiment dries under 35 ℃ of constant temperature.
Above-mentionedly be merely the specific embodiment of the present invention, but design concept of the present invention is not limited thereto, allly utilizes this design that the present invention is carried out the change of unsubstantiality, all should belong to the behavior of invading protection domain of the present invention.
