Yields, be suitable for mass production.
Above description is only the general introduction of technical solution of the embodiment of the present invention, in order to better understand the embodiment of the present invention
Technological means, and can be implemented in accordance with the contents of the specification, and in order to allow above and other mesh of the embodiment of the present invention
, feature and advantage can be more clearly understood, the followings are specific embodiments of the present invention.
Specific embodiment
Exemplary embodiment of the present invention is described in more detail below.It should be appreciated that may be realized in various forms this
It invents and should not be limited by the embodiments set forth herein.It is to be able to thoroughly understand on the contrary, providing these embodiments
The present invention, and the scope of the present invention can be fully disclosed to those skilled in the art.
The embodiment of the present invention discloses a kind of compound enamel precious metal jewelry, comprising: noble metal green body；It is overlying on the green body
At least partly one or more layers high temperature enamel of outer surface, the processing temperature of the high temperature enamel is at 600 DEG C or more；And it is overlying on
One or more layers low medium temperature enamel outside the high temperature enamel, the firing temperature of the low medium temperature enamel are at 40 DEG C or more and low
In 600 DEG C, the low medium temperature enamel is made of raw material from the following weight: it is 40-60 parts quartzy, 10-20 parts of feldspar, and borax 5-20
Part, 5-10 parts of strontium carbonate, 5-10 parts of sodium carbonate, 1-10 parts of barium carbonate, 5-10 parts of magnesium carbonate, 5-10 parts of sodium nitrate, fluorite 5-10
Part, 0.1-1 parts of lime stone, 5-10 parts of potassium nitrate, 5-10 parts of potassium carbonate, 5-10 parts of lithium carbonate, 2-5 parts of colorant, binder
0.5-2 parts.
High temperature enamel is to pass through craft and techniques clinkering or solidification after 600 DEG C or more (usually more than 800 DEG C) roastings form
In the vitreous material of billet surface, there is quality and dicoration similar to jewel.The main ingredient of enamel is SiO2,
In can contain the inorganic matters such as Al, Na, B, it is also possible to contain a small amount of organic matter composition.High temperature enamel density is big (generally higher than
1.65g/cm3), it is hard (its Mohs' hardness is generally between 6.5-7) and crisp, be applied to this shape of precious metal jewelry compared with
When green body relatively small for complicated, size, difficulty of processing is bigger, and it is uniform to be difficult glazing, and product surface easily embrittlement, causes
Product yield is low.
Coated with quality, relatively soft (Mohs is hard outside high temperature enamel layer for the compound enamel precious metal jewelry of the embodiment of the present invention
Spend 5.5 or so) low medium temperature enamel, the firing temperature of low medium temperature enamel 40 DEG C or more (usually at 120 DEG C or more) and
Lower than 600 DEG C.Such processing temperature and relatively soft quality, so that low medium temperature enamel is convenient for uniform glazing in production,
Surface is not easy embrittlement.It is overlying on high temperature enamel layer outer surface, additionally it is possible to significantly reduce the embrittlement probability and journey of high temperature enamel layer
Degree, improves yields, is suitable for mass production.
The compound enamel precious metal jewelry of the embodiment of the present invention can have the quality and color of conventional high-temperature enamel, simultaneously
The more abundant color of product and modification flexibility ratio are assigned using low medium temperature enamel.
The low medium temperature enamel composition of raw materials of the compound enamel precious metal jewelry of the embodiment of the present invention, is matched using following parts by weight
The base-material of ratio: it is 40-60 parts quartzy, 10-20 parts of feldspar, 5-20 parts of borax, 5-10 parts of strontium carbonate, 5-10 parts of sodium carbonate, barium carbonate
1-10 parts, 5-10 parts of magnesium carbonate, 5-10 parts of sodium nitrate, 5-10 parts of fluorite, 0.1-1 parts of lime stone, 5-10 parts of potassium nitrate, potassium carbonate
5-10 parts, 5-10 parts of lithium carbonate, glaze is fired in relatively low temperature, and there is the suitable coefficient of expansion,
High temperature enamel outer surface can steadily be overlayed on.
Low medium temperature enamel firing temperature also makes the range of choice of colorant wider, in addition to the inorganic coloring of metal oxide-type
Other than agent (such as cobalt oxide, nickel oxide, iron oxide, copper oxide, chromium oxide etc.), it is also an option that individual toner,
Such as the mixing of benzidine yellow class, phthalein blueness class, forever solid orange based colorant etc. or toner and inorganic colourant.So
It assigns the more abundant color of enamel precious metal jewelry and effect is presented.
It also include binder in low medium temperature enamel raw material, the addition of binder improves the stability of low medium temperature enamel layer,
And make it easier to the outer surface for being attached to high temperature enamel layer and noble metal green body.Binder can be selected from algin, Radix Astragali
One of glue, Arabic gum, galactomannan gum are a variety of.
High temperature enamel and low medium temperature enamel all can be one or more layers, and necessarily completely overlapped between each layer, so
Increasingly complex changeable moulding can be designed for ornaments.
Noble metal can be Au Ag Pt Pd or their any alloy.Some higher precious metal jewelry matter of purity
Ground is softer, using composite construction of the invention, fires high temperature enamel first in noble metal green body outer surface, can promote ornaments
Anti-deformation.Ornaments can be various types of ornaments such as ring, bracelet, necklace, pendant, ear pendant, hair decorations, and the present invention is to this
Without limitation.
High temperature enamel can be hyaline layer or background color layer, and the gorgeous color of ornaments can be mentioned mainly by low medium temperature enamel layer
For.In this way, the colorant or pigment of the harmful substances such as leaded may not necessarily be added in high temperature enamel glaze, the peace of product is improved
Quan Xing.In the environment of current people are to health and safety pay attention to day by day, compound enamel precious metal jewelry of the invention can have
There is higher commercial value.
