A kind of energy-saving fire-free transparent glaze and preparation method thereof

Abstract

The invention discloses an energy-saving baking-free transparent glaze. The glaze contains the following ingredients in parts by weight: 100-120 parts of glass powder and 50-80 parts of chemical raw materials, wherein the glass powder and the chemical raw materials are uniformly mixed and then are subjected to water-added grinding so as to obtain powder with the grain size of 200 to 400 meshes; the chemical raw materials contain the following ingredients in parts by weight: 9-18 parts of NaOH, 11-16 parts of Al(OH)3, 12-16 parts of K2CO3, 5-6 parts of MgO, 0.5-1 part of TiO2, 9-18 parts of CaCO3 and 3-5 parts of Ba(OH)2. According to the baking-free transparent glaze disclosed by the invention, the energy consumption and resource consumption are lowered greatly compared with those of the original processes, and transparency, pinholes, skipping glazes and glazed-surface tangerine peels, which are made through baking the product, all meet national product quality requirements.

Description

technical field [0001] The invention relates to the technical field of formula glaze, in particular to an energy-saving transparent glaze product that can be used without firing and a preparation method thereof. Background technique [0002] Enamel is a thin layer of glassy substance that covers ceramic products. At present, the glaze on the market is frit glaze. The traditional frit glaze preparation process is to first fire the frit, and then mix the resulting frit with plastic clay for fine grinding, that is: raw material crushing-mixing-heating-melting-quenching-addition Material - ball mill - glaze. The production process has many steps, and a large amount of heat energy is consumed in the process of preparing frit. The heat energy in the north is mainly generated by burning coal, which not only requires a large amount of coal consumption, but also the dust and carbon dioxide produced by burning coal will seriously pollute the environment. [0003] The main reasons fo...

Problems solved by technology

In order to change this situation, there are two major methods currently being adopted: 1) Reduce the firing temperature of enamel. The common methods are to adjust the enamel formula, increase the types of fluxes, select new low-temperature fast-fired raw materials, and use nano-powder as raw materials. , these methods reduce the firing temperature to a certain extent, but they cannot fundamentally solve the problem; 2) The development of non-fired glaze, this process is currently in the laboratory research stage, and two major problems have been encountered during the research process: ① The selection of unfired glaze raw materials has so far failed to select raw materials suitable for industrial production; ② particle size control, if the particle size is too large, it cannot meet the product quality requirements, and the particle size is too small, consuming a lot of mechanical energy
