Abstract
The invention discloses a lead-free black frit for ceramic preparation. The lead-free black frit for ceramic preparation is made of, by weight, 50-60 parts of SiO2, 5-15 parts of Al2O3, 5-15 parts of FeO, 1-5 parts of BaO, 5-15 parts of ZnO and 15-30 parts of B2O3. Ceramic products prepared by the lead-free black frit are black-glossy, reflective, fine in visual effect, free of lead, environment-friendly, safe and wide in application range.
Description
?
Technical field
The present invention relates to a kind of frit for preparing ceramic usefulness, be specifically related to the frit that a kind of coloured potting for preparing ceramic usefulness is used.
Background technology
The glaze of graceful black becomes the ceramic color that relatively favor in high-grade place gradually, and mostly the ceramic color of prior art is white, and black is seldom arranged; Than and the black glaze of prior art exist glaze not shiny black more; The glaze distribution of color is inhomogeneous, and is added with heavy metal lead more, and the feature of environmental protection is relatively poor.Therefore, necessary on the basis of prior art, a kind of Environmental Safety of research and development design, the frit that enamel is good, shiny black, graceful, the uniform unleaded black potting of color and luster is used.
Summary of the invention
Goal of the invention: technical problem to be solved by this invention is the deficiency that overcomes prior art, provide a kind of shiny black, graceful, the glaze slickness is good, does not add metallic lead, the frit that safety and environmental protection, the unleaded black potting that firing range is good are used.
Technical scheme: for solving above technical problem, the present invention takes following technical scheme:
The frit that a kind of unleaded black potting is used, it is processed by the raw material of following parts by weight:
SiO
250 ~ 60 parts, Al
2O
35 ~ 15 parts, FeO5 ~ 15 part, 1 ~ 5 part of BaO, 5 ~ 15 parts of ZnO, B
2O
315 ~ 30 parts.
As preferred version, the frit that above-described unleaded black potting is used, it is processed by the raw material of following parts by weight:
SiO
255 ~ 60 parts, Al
2O
310 ~ 15 parts, FeO10 ~ 15 part, BaO3 ~ 5 part, ZnO10 ~ 15 part, B
2O
320 ~ 30 parts.
As more preferably scheme, the frit that above-described unleaded black potting is used, it is processed by the raw material of following parts by weight:
SiO
255 parts, Al
2O
315 parts, FeO15 part, BaO3 part, ZnO15 part, B
2O
330 parts.
The present invention confirms the composition of the frit that unleaded black potting is used and the ratio of each component according to the specification of quality of potting with frit through a large amount of experiments, and test experience result shows that the each component proportioning is scientific and reasonable; The frit that unleaded black potting provided by the invention is used; Various physico-chemical properties meet the requirements, and it is shiny black to fire the glaze elegance that obtains, and aesthetics is high; Can be widely used in various high-grade places, the frit specific product parameter that this unleaded black potting uses is:
(degree 565, sintering point (degree) 670, softening temperature (degree) 740, ball point (degree) 1080, hemisphere point (degree) 1220, each item character meets the requirements, Functionality, quality and appealing design for thermal expansivity 72, change point (degree) 520, expansion softening temperature.
Beneficial effect: the frit that unleaded black potting provided by the invention is used is compared with prior art has following advantage:
The frit that the unleaded black potting of the ceramic usefulness of preparation provided by the invention is used, the component proportioning is scientific and reasonable, graceful, shiny black, the good visual effect of glaze especially, and do not add the metal lead, environmental protection more, safety.
