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, refer to 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 whole brushing is easy to occur the phenomenon of overweight coating often, 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 as follows:
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 back light weight sand to the no particle in surface; B) glue spraying water on priming paint is gilded/silver foil after waiting to do again; C) after foliation is finished, spray paint; Before step a, need treating that the foliation face applies one deck gold/silver oil earlier; Between step b and c, also need to spray at least one time ethene priming paint; After finish paint among the step c is waited to do, carry out dehumidifier and handle, treat that dehumidifier is finished after, under constant temperature, dry again and make finished product.
Further, need between described step b and the c through successively spraying three times ethene priming paint.
Further, the priming paint among the described step a is NC priming paint; Finish paint among the described step c is the NC finish paint.
Further, the temperature of described constant temperature is between 30-40 ℃.
As a further improvement on 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 described 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.
By the above-mentioned description of this invention as can be known, compare with prior art, the invention has the advantages that:
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, by 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 by 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: apply one deck gold/silver oil and form a gold medal/silver-colored oil reservoir at the foliation face in advance, with prevent from formally gilding/produce the problem of revealing the exact details and turning black during silver foil; Follow and use cross that thickness is moderate of NC priming paint ejection in the middle part of gold/silver-colored oil reservoir, the NC priming paint of this crux can be treated the dried back extremely no particle in surface of sand paper light weight sand to levelling and even covering all around to whole gold/silver-colored oil reservoir surface; Then at NC prime coat middle part with cross that thickness is moderate of glue (being generally oiliness glue) ejection, the glue of this crux can to around levelling and evenly covering to whole NC prime coat surface, treat to gild/silver foil on its surface again after dried; Then use ethene priming paint to spray a cross again in the middle part of gold/silver foil surface, ethene priming paint can be treated dried back sand paper light weight sand to levelling and even covering all around to whole gold/silver foil surface; 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 finished, 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, do not repeat them here.
Embodiment two
The step of present embodiment and above-described embodiment one is basic identical, and its main distinction is that the gold of present embodiment/successively spray on the silver foil surface 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 by spraying polish lacquer, can effectively strengthen gold/silver foil light effect to whole NC top coat layer surface to levelling and even covering all around; In addition, present embodiment dries under 40 ℃ of constant temperature.
Embodiment three
The step of present embodiment and above-described embodiment two is basic identical, and its main distinction is that present embodiment dries under 35 ℃ of constant temperature.
Above-mentioned only is the specific embodiment of the present invention, but design concept of the present invention is not limited thereto, and 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.
