Problems solved by technology

At present, the sanitary ceramic sanitary ware on the market has a glossy white opaque glaze with a single visual and tactile effect. Therefore, developing different styles of sanitary ceramic sanitary ware products is one of the goals of R&D professionals.
[0003] Low-gloss matte glaze has been used in the production of architectural ceramic tiles, but in the production process of sanitary ceramics, due to its special shape structure and harsh firing system, higher firing temperature and higher firing Cycle, resulting in color distortion, uneven glaze and other problems

Abstract

The invention discloses a sanitary ceramic sanitary appliance warm and humid glaze with soft impression and a preparation process thereof, and relates to the warm and humid glaze with the soft impression for the sanitary appliance and a preparation method thereof. The warm and humid glaze with the soft impression is characterized in that the warm and humid glaze further comprises a component capable of producing a baryta feldspar and slawsonite microcrystal structure; the glaze is prepared from, by weight, 45.29-54.42% of SiO2, 13.01-22.88% of Al2O3, 7.93-11.04% of CaO, 0.12-3.98% of MgO, 1.26-5.50 % of K2O, 0.72-3.83% of Na2O, 0.05-10.50% of ZrO2, 0.56-1.89% of B2O3, 2.76-8.95% of ZnO , 4.39-12.98% of BaO and 0-5.35% of SrO; the warm and humid glaze is prepared by weighing, ball milling,iron-removed treatment and ageing, and sprayed on the base of sanitary appliances, the thickness is about 1mm, the firing step is carried out, the enamelled sanitary appliance base is placed in a tunnel kiln and fired with conventional bright flame at 1220-1280 DEG C, and after firing, the glaze surface has effects of soft look feeling and delicate touch feeling.

Description

technical field [0001] The invention relates to a soft light and warm glaze for sanitary ceramic sanitary ware and a preparation method thereof, belonging to the technical field of sanitary ceramic preparation. The soft light and warm glaze is characterized in that the formula also contains materials that can produce feldspar microcrystalline structure when fired; the glaze specifically relates to a soft light and warm glaze for sanitary ware with soft appearance, delicate touch and moist performance and its preparation process.
