A kind of frit with high transparency and preparation method thereof

Abstract

The invention discloses high-transparency frit and a preparation method thereof. The high-transparency frit is mainly composed of 10-20 parts of Al2O3, 45-55 parts of SiO2, 0.05-0.10 part of Fe2O3, 10-15 parts of CaO, 4-8 parts of MgO, 1-3 parts of K2O, 1-3 parts of Na2O, 0.01-0.03 part of TiO2, less than 0.01 part of SrO, 0.30-0.60 part of LiO2, less than 0.01 part of PbO, less than 0.01 part of ZnO, 3-6 parts of B2O3, 0.1-0.5 part of P2O5 and 1-4 parts of F chemically, and loss on ignition is 3-5%. Frit particles can be closely combined with a ceramic substrate and are free of breakaway and layering; the frit and a blank are matched in expansion coefficient, so that a fired product has a flat surface; the surface of the fired product is free of air bubbles and pinholes, and the fired product is high in glossiness and transparency; raw materials which are extremely low in lead-cadmium content are adopted for formulation, so that the frit is environment-friendly.

Description

technical field [0001] The invention belongs to the field of ceramics, and in particular relates to a high-transparency frit and a preparation method thereof. Background technique [0002] At present, the surface of glass-ceramic composite plates on the market adopts translucent or opaque opaque microcrystalline layer, and its surface decoration effect is completely dependent on different colored glass-ceramic frits and their crystallization textures, and the manufacturing cost is high. , the transparency is not good, and the color and texture are relatively simple and not rich enough. In order to achieve a certain decorative effect, some enterprises even directly use the glass phase as a method to achieve three-dimensional color, but its physical and chemical properties are very different from those of glass-ceramics, the texture is not clear, and the three-dimensional effect is not strong. Contents of the invention [0003] In order to overcome the deficiencies in the p...
