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, 50-60 parts of SiO2, 5-10 parts of Al2O3, 1-5 parts of CaO, 1-5 parts of ZnO, 10-20 parts of B2O3 and 5-10 parts of alkali metal. 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 transparent in color, glossy, smooth and clear in color development.
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 of ceramic usefulness.
Background technology
With lead is the ceramic glaze frit of main raw material; Advantages such as it is excellent to have the melting performance, and firing range is wide have bigger toxicity but contain the lead that lead frit contains to human body; And the frit that the general potting of prior art is used exists enamel bad, opaque; Can cover the material color, can not show the quality of material, and shortcoming such as the glaze slickness is relatively poor.Therefore, necessary on the basis of prior art, research and development designs a kind of Environmental Safety, transparent, glossiness is good, be difficult for loss of gloss, 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 the glaze slip performance is good, unleaded clear frit.
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
35 ~ 10 parts, 1 ~ 5 part of MgO, BaO1 ~ 5 part, 1 ~ 5 part of ZnO, B
2O
35 ~ 10 parts of 10 ~ 20 parts, basic metal.
As preferred version, above-described unleaded clear frit, it is processed by the raw material of following parts by weight:
SiO
255 ~ 60 parts, Al
2O
38 ~ 10 parts, 3 ~ 5 parts of MgO, BaO1 ~ 5 part, 3 ~ 5 parts of ZnO, B
2O
38 ~ 10 parts of 15 ~ 20 parts, basic metal.
As preferred version, above-described unleaded clear frit, it is processed by the raw material of following parts by weight:
SiO
255 parts, Al
2O
38 parts, 3 parts of MgO, 3 parts of ZnO, BaO3 part, B
2O
38 parts of 15 parts, basic metal.
As preferred version, above-described unleaded clear frit, described basic metal are K
2O or Na
2O.
The present invention confirms the composition of unleaded clear frit and the ratio of each component through a large amount of experiments, unleaded clear frit provided by the invention, and various physico-chemical properties meet the requirements, and fire the smooth exquisiteness of the glaze that obtains, good brightness, and the transparency is good.This unleaded clear frit specific product parameter is:
Thermal expansivity 58, change point (degree) 571, expansion softening temperature (degree) 640, sintering point (degree) 660, softening temperature (degree) 820, ball point (degree) 960, hemisphere point (degree) 1120, each item character meets the requirements.
Beneficial effect: unleaded clear frit provided by the invention is compared with prior art has following advantage:
Unleaded clear frit provided by the invention is formed and proportioning according to the best of the preferred frit of a large amount of experiments, and experimental result shows that the each component proportioning is scientific and reasonable; The Ceramic glaze slickness for preparing with frit provided by the invention is good, enamel is good; Transparent light, glaze slip performance are good, do not add lead, and the Environmental Safety performance is high; Its preparation cost is low, and the scope of application is more extensive.
