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

Embodiment 1

[0028] A low-temperature quick-firing matte glaze, which comprises the following components in terms of parts by weight: 100 parts of glass powder, 90 parts of chemical raw materials; after mixing the two, add 65 parts of water and grind them into 320-mesh powder; among them, glass The powder is glass powder prepared by crushing and grinding after recycling waste glass. The waste glass is a composition of ordinary flat glass and high borosilicate glass, wherein the weight ratio of ordinary flat glass and high borosilicate glass is 2:1; , chemical raw materials include the following components by weight and number ratio: polyethylene glycol: 25 parts, aluminum hydroxide: 11 parts, talcum powder: 8 parts, calcium phosphate: 7 parts, calcium oxide: 9 parts, fluorite: 20 parts, stannous chloride: 10 parts.

Embodiment 2

[0030] The preparation method of the low-temperature quick-firing matte glaze comprises the following steps:

[0031] A. Utilize recycled waste glass to purify and pulverize and grind to prepare glass powder. The waste glass adopts the composition of ordinary flat glass and high borosilicate glass, wherein the weight and number ratio of ordinary flat glass and high borosilicate glass is 2:1, spare;

[0032] B, take chemical raw material in proportion, and described chemical raw material comprises following component by weight ratio calculation: polyethylene glycol: 25 parts, aluminum hydroxide: 11 parts, talcum powder: 8 parts, calcium phosphate: 7 parts , calcium oxide: 9 parts, fluorite: 20 parts, tin protochloride: 10 parts; mixing for subsequent use;

[0033] C. Fully mix 100 parts by weight of glass powder obtained in step A with 90 parts by weight of chemical raw materials obtained in step B and add 65 parts by weight of water, ball mill, sieve, and control the product ...

Embodiment 3

[0035] In the technical scheme of the present invention, the electric furnace trial firing and further ball milling glaze trial firing show that the selection of materials and the granularity of the glaze, these two key technical indicators, have a great impact on the melting state of the glaze and the relationship between the glaze and the green body. The degree of combination has decisive significance, especially the selection and proportion of materials, which will also have an important impact on the technical indicators such as matteness, pinholes, glaze jumping and glaze orange peel of the fired glaze. Therefore, the material of the present invention Proportioning and particle size selection are the core technical solution of the present invention and an important basis for the beneficial effects of the present invention. The relevant comparative experiments and data are shown below.

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...
