Abstract
The invention discloses a lead-free transparent frit for ceramic preparation. The lead-free transparent frit for ceramic preparation is made of, by weight, 60 parts of SiO2, 20 parts of Al2O3, 5 parts of MgO, 30 parts of CaO and 20 parts of K2CO3. The optimal composition and proportion are determined by screening from a great amount of tests according to the property requirements of the lead-free transparent frit. Test results show that the lead-free transparent frit for ceramic preparation is scientific and reasonable in component proportion, and ceramic products prepared by the lead-free transparent frit are fine in glaze smoothness, excellent in enamel, especially transparent and bright, free of lead, environment-friendly 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 a kind of unleaded clear frit for preparing ceramic usefulness.
Background technology
Ceramic has the advantage of high compactness, good decorating effect because of it; Fields such as daily necessities, material of construction, artwork have been widely used in; But the frit that the general potting of prior art is used is added with heavy metal lead more, and the feature of environmental protection is relatively poor, and general ceramic glaze all is opaque; Luminance brightness is relatively poor, and the color and luster sense is not good.Therefore, necessary on the basis of prior art, research and development design a kind of Environmental Safety, transparent, light, the uniform unleaded clear frit of color and luster.
Summary of the invention
Goal of the invention: technical problem to be solved by this invention is the deficiency that overcomes prior art, and a kind of metallic lead that do not add is provided, and safety and environmental protection, the transparency are good, can show the quality of material, and be transparent, the unleaded clear frit of light.
Technical scheme: for solving above technical problem, the present invention takes following technical scheme:
A kind of unleaded clear frit, it is processed by the raw material of following parts by weight:
SiO
250 ~ 60 parts, Al
2O
310 ~ 20 parts, MgO1 ~ 5 part, 20 ~ 30 parts of CaO, 10 ~ 20 parts of an alkali metal salts.
As preferred version, above-described unleaded clear frit, it is processed by the raw material of following parts by weight:
SiO
250 ~ 55 parts, Al
2O
310 ~ 15 parts, MgO3 ~ 5 part, 20 ~ 25 parts of CaO, 10 ~ 15 parts of an alkali metal salts.
As more preferably scheme, above-described unleaded clear frit, it is processed by the raw material of following parts by weight:
SiO
255 parts, Al
2O
315 parts, MgO3 part, 25 parts of CaO, 15 parts of an alkali metal salts.
As preferred version, above-described unleaded clear frit, described an alkali metal salt are K

The present invention is according to the specification of quality of potting with clear frit, confirms the ratio of the composition and the each component of unleaded clear frit through a large amount of experiments, and test experience result shows that the each component proportioning is scientific and reasonable; Unleaded clear frit provided by the invention, various physico-chemical properties meet the requirements, and fire the smooth exquisiteness of the glaze that obtains; The transparency is good; Glossiness is good, and temperature of fusion is low, and this unleaded clear frit specific product parameter is:
Thermal expansivity 62, change point (degree) 753, expansion softening temperature (degree) 820, sintering point (degree) 840, softening temperature (degree) 970, ball point (degree) 1080, hemisphere point (degree) 1190, each item character meets the requirements, Functionality, quality and appealing design.
Beneficial effect: unleaded clear frit provided by the invention is compared with prior art has following advantage:
The unleaded clear frit of the ceramic usefulness of preparation provided by the invention, the each component proportioning is scientific and reasonable, and the transparent light of Ceramic glaze, the glaze slip performance that prepare with frit provided by the invention are good, and do not add the metal lead, environmental protection, safety performance height.
