Embodiment 1

[0017] This embodiment provides a method for preparing thermal shock-resistant and antibacterial low-temperature reinforced porcelain, which specifically includes the following steps:

[0018] S1. Preparation of green body: the green body raw material composition is composed of the following components in parts by weight: 20 parts of Dehua kaolin, 12 parts of potassium feldspar, 4 parts of nano-hexacyclic stone powder, 8 parts of dolomite and 10 parts of flux for the green body part, the flux for the green body is sodium fluorosilicate, Chenwan porcelain stone and boronite mixed in a mass ratio of 3:2:2; the green body preparation method is as follows: step S11: mix the green body raw materials and add water Then use alumina balls as the ball milling medium to carry out ball milling, pass through a 500-mesh sieve after ball milling for 30 minutes, and remove iron to obtain the green body sludge; Step S12: The green body sludge in step S11 is sequentially dehydrated, vacuum mudd...

Embodiment 2

[0022] This embodiment provides a method for preparing thermal shock-resistant and antibacterial low-temperature reinforced porcelain, which specifically includes the following steps:

Abstract

The invention discloses a preparation method of thermal-shock-resistant antibacterial low-temperature strengthened porcelain. The preparation method comprises the following steps of preparing a green body, preparing glaze water, glazing, airing, and sintering for 4-6 hours in an oxidizing atmosphere, wherein the highest sintering temperature is 1080-1120 DEG C, the raw materials of the green body comprise Dehua kaolin, potassium feldspar, nano six-ring stone powder, dolomite and a fluxing agent for the green body, and the glaze water is prepared from the following raw materials: quartz powder, albite, glaze ash, a nano antibacterial agent and a fluxing agent for glaze. The nano six-ring stone powder is added into the green body, the nano antibacterial agent is added into the glaze water, so that the green body and the glaze layer have good antibacterial performance, the fluxing agent prepared by mixing the sodium fluosilicate, the aged bay chinastone and the borocalcite is respectively added into the green body and the glaze water, the primary firing temperature can be reduced to 1080-1120 DEG C, and the high-wear-resistance and high-strength low-temperature strengthened porcelain which has the water absorption rate of 2+ / -0.5% and the glossiness of 90 or more, does not crack after being quenched at the temperature of 180-20 DEG C and has good blank glaze adaptability is prepared.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a preparation method of thermal shock-resistant and antibacterial low-temperature reinforced porcelain. Background technique [0002] Strengthened porcelain is the most suitable porcelain for high-end hotels and restaurants. In addition to the characteristics of general high-grade fine porcelain, it also has unique properties of high strength, acid and alkali resistance, and easy washing. It can withstand the impact of kitchen work and is not easy to damage. , suitable for mechanical washing, microwave ovens, and electric ovens. It is the most ideal porcelain for Chinese and Western restaurants, restaurants and modern families. [0003] The main categories of strengthened porcelain are high-alumina, high-silicon, magnesia and bone-reinforced porcelain. For example, the Chinese patent document (CN111423207A) discloses a high-performance magnesia-reinforced porcelain b...
