Abstract
The invention discloses a lead-free matte frit for preparing ceramics. The lead-free matte frit is prepared from raw materials in parts by weight: 40-50 parts of SiO2, 5-10 parts of Al2O3, 2-5 parts of MgO, 10-20 parts of B2O3, 5-10 parts of ZrO2 and 2-5 parts of alkali metal. According to the lead-free matte frit provided by the invention, all the components are proportioned scientifically and reasonably, the effects of safety and the environmental protection are realized, the sintering process is simple, the matte effect is good, the glaze slip property is good, the color is uniform, the glaze quality is high, the sintering property is good, and the applicable range is wide.
Description
?
Technical field
The present invention relates to a kind of frit for preparing ceramic usefulness, be specifically related to a kind of unleaded mute light frit of ceramic usefulness.
Background technology
The raising gradually of Along with people's standard of living, people require increasingly highly to standard of living, and ceramic is daily staple; But the frit that existing potting is used contains heavy metal lead, has certain toxicity, and exists temperature of fusion high; Etc. shortcoming, therefore, necessary on the basis of prior art; Research and development design temperature of fusion is moderate, the unleaded mute light frit that enamel is good, enamel is high.
Summary of the invention
Goal of the invention: technical problem to be solved by this invention is the deficiency that overcomes prior art, provides that good, the mute light effect of a kind of glaze slickness is good, enamel is good, and color and luster evenly, the slurry performance is good, the unleaded mute light frit that firing property is good.
Technical scheme: for solving above technical problem, the present invention takes following technical scheme:
A kind of unleaded mute light frit, it is processed by the raw material of following parts by weight:
SiO
240 ~ 50 parts, Al
2O
35 ~ 10 parts, 2 ~ 5 parts of MgO, B
2O
310 ~ 20 parts, ZrO
22 ~ 5 parts of 5 ~ 10 parts, basic metal.
As preferred version, above-described unleaded mute light frit, it is processed by the raw material of following parts by weight:
SiO
240 ~ 45 parts, Al
2O
35 ~ 8 parts, 2 ~ 4 parts of MgO, B
2O
310 ~ 15 parts, ZrO
23 ~ 4 parts of 5 ~ 8 parts, basic metal.
As preferred version, above-described unleaded mute light frit, it is processed by the raw material of following parts by weight:
SiO
240 parts, Al
2O
35 parts, 2 parts of MgO, B
2O
310 parts, ZrO
22 parts of 5 parts, basic metal.
As preferred version, above-described unleaded mute light frit, described basic metal can be K
2O or Li
2O.
The present invention confirms that through a large amount of experiments the best of unleaded mute light frit is formed and the ratio of each component, and test experience result shows unleaded mute light frit provided by the invention, superior performance, and the specific product parameter is:
Thermal expansivity 69, change point (degree) 653, expansion softening temperature (degree) 700, sintering point (degree) 700, softening temperature (degree) 770, ball point (degree) 910, hemisphere point (degree) 980.
Beneficial effect: unleaded mute light frit provided by the invention is compared with prior art has following advantage:
Unleaded mute light frit provided by the invention, the each component proportioning is scientific and reasonable, need not to add metallic lead in the frit, and environmental protection, safety performance are higher, and sintering technology is simple, and good springiness, and physical strength is big, good thermal shock stability.
