Abstract
The invention discloses a good-waterproofness lead-free transparent frit for preparing ceramics. The lead-free transparent frit is prepared from following raw materials in parts by weight: 50-60 parts of SiO, 5-10 parts of Al2O3, 1-5 parts of TiO2, 1-5 parts of CaO, 1-5 parts of ZnO and 10-20 parts of B2O3. According to the good-waterproofness lead-free transparent frit for preparing ceramics provided by the invention, the optimal composition and proportion are determined by the screening of a large amount of experiment, all the components are proportioned scientifically and reasonably, particularly, the waterproof property is good, water can not leak easily, the service life is long, lead does not exist, and the environment is protected.
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 good waterproof performance of ceramic usefulness.
Background technology
The ceramic goods are widely used in the daily life, as are widely used in kitchen, toilet, fields such as outdoor bathing place; But the frit that the general potting of prior art is used exists water resistance relatively poor, the long-time use, and ceramic tile is permeable easily; Bring inconvenience, and the pottery of prior art exists opaquely more, can cover the material color; Can not show the shortcomings such as quality of material, and be added with heavy metal lead more, the feature of environmental protection is relatively poor.Therefore, necessary on the basis of prior art, a kind of water resistance of research and development designs is good, the unleaded clear frit of Environmental Safety, transparent good waterproof performance.
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, safety and environmental protection, transparent good, the unleaded clear frit of good waterproof performance.
Technical scheme: for solving above technical problem, the present invention takes following technical scheme:
A kind of unleaded clear frit of good waterproof performance, it is processed by the raw material of following parts by weight:
SiO
250 ~ 60 parts, Al
2O
35 ~ 10 parts, TiO
21 ~ 5 part, 1 ~ 5 part of CaO, 1 ~ 5 part of ZnO, B
2O
310 ~ 20 parts.
As preferred version, the unleaded clear frit of above-described good waterproof performance, it is processed by the raw material of following parts by weight:
SiO
250 ~ 55 parts, Al
2O
35 ~ 8 parts, TiO
21 ~ 3 part, 1 ~ 3 part of CaO, 1 ~ 3 part of ZnO, B
2O
310 ~ 15 parts.
As more preferably scheme, the unleaded clear frit of above-described good waterproof performance, it is processed by the raw material of following parts by weight:
SiO
250 parts, Al
2O
38 parts, TiO
23 parts, 3 parts of CaO, 3 parts of ZnO, B
2O
315 parts.
The present invention is according to the specification of quality of potting with clear frit, confirms composition and the ratio of each component of the unleaded clear frit of good waterproof performance through a large amount of experiments, the unleaded clear frit of good waterproof performance provided by the invention; Various physico-chemical properties meet the requirements; Fire the smooth exquisiteness of the glaze that obtains, the transparency is good, and especially water resistance is good; Be difficult for permeable, long service life.The unleaded clear frit specific product parameter of this good waterproof performance is:
Thermal expansivity 66, change point (degree) 560, expansion softening temperature (degree) 640, sintering point (degree) 650, softening temperature (degree) 780, ball point (degree) 920, hemisphere point (degree) 1060, each item character meets the requirements, Functionality, quality and appealing design.
Beneficial effect: the unleaded clear frit of good waterproof performance provided by the invention is compared with prior art has following advantage:
The unleaded clear frit of the good waterproof performance of the ceramic usefulness of preparation provided by the invention is formed and proportioning according to the best of the preferred frit of a large amount of experiments, and the Ceramic glaze slickness for preparing with frit provided by the invention is good; Especially water resistance is good; Be difficult for permeable, long service life, and do not add the metal lead; Environmental protection, safety performance height, the scope of application is extensive.
