Description
The present invention relates to a kind of cover-coat for colour on glazed ceramics and processing and manufacturing trailing and goods.It belongs to the decoration and the protection on ceramic over-glaze decoration surface, and it comprises the composition of cover-coat for colour on glazed ceramics, processing and manufacturing trailing and cover layer ceramic.
At present, the flux that is adopted in ceramic industry all contains plumbous oxide (PbO).Because this oxide compound can make flux meltable and the melt temperature scope of broad arranged, can improve the refractive index and the elasticity of glass, can make more horn of plenty of paint color, can also slow down alkalimetal ion dissociating in glass, have and the matched thermal expansivity of most of enamel.Therefore in colour on glazed ceramics, also can't do without this component of plumbous oxide from ancient times to the present.But other metal oxide in plumbiferous compound and the colour on glazed ceramics such as the compound of cadmium etc. all are deleterious, especially the tableware of decorating with over-glaze pigment, drinking utensils, tea set etc., in environment for use, poisonous components such as lead, cadmium can weather and stripping, harm people's health.This has just proposed a premium properties that should keep leaded over-glaze pigment, reduces the research topic of plumbous quantity of cadmium release again as far as possible.In recent years, it is more to be engaged in the department of development " colorant on the acidproof leadless glaze ", " the unleaded flux of ceramic pigment on the glaze ".
Chinese patent application numbers 911016120 discloses a kind of glass composition, and its purpose provides a kind of unleaded surrogate, and its formation is:
Silicon-dioxide 38-50%
Zirconium white 9-17%
Boron oxide 26-50%
Sodium oxide or (with) potassium oxide 4-15%
Lithium Oxide 98min 2-8%
Titanium oxide 0-15%
Aluminum oxide 0-15%
Stannic oxide 0-10%
Cerium oxide 0-10%
Magnesium oxide 0-10%
Zinc oxide 0-10%
Bismuth oxide 0-8%
Calcium oxide 0-5%
Plumbous oxide 0-5%
Fluorochemical 0-2%
The glass flux composition of forming in order to constitute a kind of enamel composition, is applied to them on goods that burnt till, and twice firing plays the decoration provide protection.Its weak point is:
The a chemical stability is bad, low in glossiness;
B can influence the colour generation of some color to the paint color bad adaptability, causes aberration big, makes the original picture distortion;
The c thermal expansivity is big, easily causes picture crackle or burst porcelain;
The d twice firing, complex process;
E is owing to contain a large amount of ZrO in the component
2, cause the glass milkiness transparency bad.
F is only limited to and is used for leadless glaze.
The objective of the invention is to avoid above-mentioned weak point of the prior art and a kind of premium properties that can keep ceramic leaded over-glaze pigment fully is provided, can reduce the plumbous quantity of cadmium release of picture on the glaze again greatly, suitable picture cracking, the ideal cover-coat for colour on glazed ceramics that the water white transparency light is firm of can not causing of, thermal expansivity very little to all pigment colour generation influences.
The present invention also aims to provide a kind of once-firing method of very easy processing decoration cover layer and decorate the various ceramics of protection, thereby thoroughly avoided the harm that all pigment may bring on the picture on the glaze with this method.
Purpose of the present invention can reach by following measure:
Cover-coat for colour on glazed ceramics material of the present invention is made of following component:
A is by PbO, B
2O
3, SiO
2The main body composition of forming;
The b viscosity modifier;
C is from ZnO, TiO
2, SnO
2In at least a colour generation auxiliary agent that chooses.
The key problem in technology of cover-coat for colour on glazed ceramics prescription of the present invention is to make it to have suitable thermal expansivity and to the high-fidelity performance of all various pigment colour generations.
PbO-B
2O
3-SiO
2The stabilizing network structure of system is given the high glossiness of glass, wide melt temperature scope, lower thermal expansivity and high chemical stability, PbO and the B in the main body composition in addition
2O
3Colour generation to pigment has outstanding contributions.The unleaded flux of this this premium properties is difficult to reach.
Viscosity modifier is the indispensable important component of the present invention, and is because suitable cover layer viscosity can guarantee that picture pigment does not fade in roasting burning process, especially particularly evident for the iron oxide red picture effect that easily fades.
The cover layer is introduced from ZnO, TiO in forming
2, SnO
2In the colour generation auxiliary agent that chooses yes helps the colour generation of shades of colour in sintering process, particularly help gold size and grow up and make its colour generation pure for the golden red picture.Their adding simultaneously makes that also glass structure is more form compact and stable, has reduced plumbous quantity of cadmium release to greatest extent.
Why the present invention does not introduce basic metal of the prior art and alkaline earth metal oxide, is because their affiliation that adds increases the thermal expansivity that covers layer, causes the picture cracking, even can cause burst porcelain.
Purpose of the present invention can also reach by following measure: cover-coat for colour on glazed ceramics of the present invention, and the compositing range of each component is:
Main body composition 84%-93%
Viscosity modifier 3.45%-9.63%

The e discharging, oven dry.
The cover layer powder of oven dry allocated with silk screen printing oil, and material oil ratio 1: 0.8-1.0 prints additional one deck cover layer on silk screen marble paper out of the press, has just made to have the marble paper that covers layer material.
As marble paper on the common glaze, the marble paper that will have the cover layer is attached on the ceramic of desire decoration, and roasting burning insulation is ten minutes under 800-850 ℃ of temperature, and firing time is about 3 hours.Once can burn till the ceramic that has the protective guard layer.
Can decorate the ceramic of the useful over-glaze pigment decoration of protection institute with cover-coat for colour on glazed ceramics material of the present invention and processing decoration method of the present invention; the decorating ceramic products that is particularly useful for cooker, tableware, kitchenware, the goods picture lead release behind the Decorative Cover layer is less than 0.3mg/dm
2, quantity of cadmium release is less than 0.10mg/dm
2And kept the color of original picture.
The present invention will now be further detailed embodiment:
The present invention has following advantage compared to existing technology:
1, to reducing ceramic glazing dyestuff Lead and cadmium amount remarkable result is arranged, lead release can be reduced to 0.3mg/dm2, quantity of cadmium release can be reduced to 0.10mg/dm2 And the glossiness height, chemical stability is good, not only reduces Lead and cadmium, and protective action is also played in the murder by poisoning of other elements in the pigment.
2, good to paint color adaptability, the transparency height, aberration is little, thereby makes well colour generation of various pigment, comprises iron oxide red and golden red, does not make the original picture distortion.
3, thermal coefficient of expansion is lower, can not cause picture crackle or burst porcelain.
4, once-firing has been simplified technology.
5, the wearing and tearing of picture on the glaze have been avoided.
