Abstract
The invention discloses frit with a high initial melting point and a high expansion coefficient and a preparation method of the frit. Raw materials for preparation of the frit comprise quartz, non-calcined alumina, lime stone, potash feldspar, sodium carbonate and borax. The frit is colorless and semi-transparent, has better gloss and has a higher initial melting point and a larger expansion coefficient, air pores are avoided due to the high initial melting point, and the technical problem of a deformation defect caused due to a small expansion coefficient of cover glaze and a larger expansion coefficient of a body is solved by the aid of the larger expansion coefficient of the frit.
Description
Technical field
The invention belongs to ceramic field, be specifically related to frit of a kind of high beginning fusing point high expansion coefficient and preparation method thereof.
Background technology
Be accompanied by people more and more higher to ceramic favorable rating, everybody has also had higher requirement to ceramic quality. And the base substrate of ceramic and property of glaze are the keys of ceramic, directly determine the quality of ceramic. Burn out fast good ceramic and will produce direct contacting with the economic benefit of enterprise industrial can realization. Frit is the important component part of ceramic, can directly act in the middle of glaze, reaches the object that improves ceramic product quality. The high expansion frit of high beginning fusing point is widely used in the middle of Ceramic Tiles, mainly improves the coefficient of expansion of base substrate and glaze, and the binding ability of base glaze is strengthened, and high beginning fusing point can be realized burning till fast of Ceramic Tiles.
The preparation technology of high beginning fusing point high expansion coefficient frit and the preparation technology of common frit are basic identical, but because it has more special performance, are different from again common frit.
Summary of the invention
The object of the present invention is to provide frit of a kind of high beginning fusing point high expansion coefficient and preparation method thereof.
The technical solution used in the present invention is:
A frit for high beginning fusing point high expansion coefficient, by mass parts, its main chemical composition is as follows: SiO244～50 parts, Al2O315～20 parts, Fe2O3< 0.2 part, TiO2< 0.05 part, CaO15～20 part, MgO0～2 part, K2O3～7 part, Na2O5～10 part, B2O30～2 part.
As preferably, described frit is mainly prepared from by following raw material: quartzy, non-calcined alumina, lime stone, potassic feldspar, soda ash and borax.

A preparation method for high beginning fusing point high expansion coefficient frit, comprises the following steps:
(1) take raw material, mix;
(2) melting at 1500～1600 DEG C of temperature, is incubated 2～3 hours;
(3) blowing shrend, oven dry obtain high beginning fusing point high expansion coefficient frit;
The composition of described frit as claim 1-6 any one the above.
The invention has the beneficial effects as follows:
(1) frit has high expansion coefficient, and its coefficient of volume expansion has reached 29 × 10-6/ DEG C, and the coefficient of expansion coefficient of expansion little, base substrate that can solve cover-coat enamel is larger, causes product to occur the defect of serious deformation. By add high expansion coefficient frit in cover-coat enamel or ground-coat enamel, thus the coefficient of expansion of coupling base glaze, the flatness of adjustment product.
(2) frit has high beginning fusing point, and Al and Si are the important composition materials of glass frit, and these structures can ensure the stability of frit, and the content that increases Al composition in frit can improve the beginning fusing point of frit. Owing to there being a large amount of igloss in raw glaze, igloss can vapor away in the time of high temperature, at this moment may occur gas hole defect, and high beginning fusing point frit has passed through high temperature solute, discharge moisture and the carbonate in material, in the time that it joins in raw glaze, can reduce or avoid glaze to produce pore. Because frit possesses high beginning fusing point, can realize and increase brick programming rate, enhance productivity.
(3) frit of high beginning fusing point high expansion coefficient of the present invention, glossiness is good, translucent, has good artistic appreciation.
