CN103387421A - Ceramic glaze with nanometer self-cleaning sterilization function and using method of ceramic glaze - Google Patents

Abstract

The invention relates to ceramic glaze with a nanometer self-cleaning sterilization function and a using method of the ceramic glaze. The ceramic glaze comprises base glaze and cover glaze, wherein the ceramic glaze has the characteristic that Ag2O and ZnO are introduced as nanometer composite antibacterial agent while cover glaze particles are refined, so that the cover glaze has a nanometer-level split-phase structure and self-sterilization capacity; and daily ceramic products are obtained by once sintering within a temperature range of 1200 DEG C to 1250 DEG C. The ceramic glaze has the advantage of further having special effects of killing bacteria and restraining bacterial reproduction under a certain photo-thermal condition while having easy-cleaning performance, so that the work of the people for cleaning ceramic tableware is greatly relieved. Moreover, the materials used by the ceramic glaze are natural mineral materials which are not only rich in resource and low in price, but also free of any side effect to the human body, and therefore, the market prospect is wide.

Description

A kind of ceramic glaze and using method thereof with Nano self-cleaning sterilizing function

Technical field

The present invention relates to the domestic ceramics technical field, particularly a kind of ceramic glaze and using method thereof with Nano self-cleaning sterilizing function.

Background technology

Domestic ceramics is widely used in daily life with advantages such as it are attractive in appearance, practical.Although its surperficial glaze layer is quite fine and close and smooth, but the restriction due to production technique, still inevitably there is small pin hole and concavo-convex in its surface, some pollutents that it is in use contacted with it, under the effect of the multiple physics such as Van der Waals force, capillary force, hydrogen bond or chemical force, easily accumulate in the concavo-convex place on its surface or enter in micropore and cause health concerns.Although market has self cleaning enamel to sell now, but it is only by further adjusting the compactness extent of glaze, to reach effect easy to clean, but also can cause the amount reproduction of the microorganism such as domestic ceramics surface bacteria due to these pollutents, user's health is produced and threatens.Therefore present self cleaning enamel glaze can't meet the requirement of people to high-quality life.

Summary of the invention

The technical problem to be solved in the present invention is to provide that a kind of preparation technology is simple, with low cost, health environment-friendly and have ceramic glaze and the using method thereof of Nano self-cleaning sterilizing function.

Technical scheme of the present invention is: a kind of ceramic glaze with Nano self-cleaning sterilizing function, comprise ground glaze layer, and the cover coat that forms on ground glaze layer, it is characterized in that:

The composition of ground glaze layer is by weight percentage: quartzy 35-40%, albite 20-30%, aluminium sesquioxide 8-10%, Suzhou soil 2-5%, calcite 4-10%, talcum 2-8%, Lithium Oxide 98min 1-3%, frit 1-5%, zinc oxide 2-5%;

The composition of cover coat is by weight percentage: quartzy 15-25%, albite 15-30%, Suzhou soil 10-25%, calcite 8-15%, rhombspar 2-6%, frit 20-35%, nano antibacterial agent 5-10%, Lithium Oxide 98min 1-3%;

The chemical weight percentage composition of above-mentioned frit is: K ₂O 2-5%, CaO 4-8%, ZnO 5-8%, Al ₂O ₃7-10%, SiO ₂6-15%, B ₂O ₃50-55%, Li ₂O 6-18%.

Described nano antibacterial agent is the Ag of median size less than 50nm ₂O and ZnO nano complex antimicrobials.

Ag in described complex antimicrobials ₂The weight ratio of O and ZnO is 70:30.

Described using method with ceramic glaze of Nano self-cleaning sterilizing function is characterized in that according to following steps:

(1), form and prepare respectively particle diameter D by ground glaze layer and cover coat raw material ₅₀≤ 5 μ m and D ₅₀The glaze slip of≤100nm;

(2), the ground glaze layer slurries are sprayed uniformly on biscuit of ceramics, its thickness is 0.8-1mm, dries;

(3), cover coat glaze slurries are sprayed uniformly on ground glaze layer, its thickness is 0.2-0.5mm, after base substrate is carried out drying;

(4), fire the acquisition goods under 1200-1250 ℃ of temperature, insulation 40-60min condition.

The present invention is under the prerequisite of the basic technology condition that does not change the domestic ceramics technological process, form and obtain having the nano level phase separation structure and from the glaze slip of antibacterial ability by designing new glaze, this glaze slip is when having performance easy to clean, under certain light and heat condition, the special-effect that also has kill bacteria and anti-bacteria breeding, thereby greatly alleviated the work of people's cleaning ceramic tableware, and the present invention is raw materials used be natural mineral raw not only originate enrich cheap, and without any side effects to human body, therefore have the wide market space.
