A kind of low-temperature quick-firing matt glaze and preparation method thereof

Abstract

The invention discloses a low-temperature fast-firing matte glaze, which comprises the following components according to the weight ratio: 100-120 parts of glass powder, 75-105 parts of chemical raw materials; the two are mixed and ground to 200 parts by adding water. -400 purpose powder, wherein, the chemical raw material comprises the following components in terms of parts by weight: polyethylene glycol: 20-25 parts, aluminum hydroxide: 10-15 parts, talcum powder: 7-10 parts, phosphoric acid Calcium: 6‑9 parts, calcium oxide: 6‑9 parts, fluorite: 18‑23 parts, stannous chloride: 9‑12 parts. The non-fired matt glaze developed by the present invention not only greatly reduces energy and resource consumption compared with the original technology, but also the matt degree, pinhole, glaze jump and glazed orange peel of the obtained product meet the national product quality requirements.

Description

technical field [0001] The invention relates to the technical field of formula glaze, in particular to an energy-saving matte glaze product 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 for making raw materials into frits at h...

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
