Preparation method of high-emissivity far-infrared emission domestic ceramic

Abstract

The invention relates to a far-infrared emission domestic ceramic technology, in particular to a preparation method of high-emissivity far-infrared emission domestic ceramic, which comprises the following steps: taking a domestic ceramic blank, adding far-infrared ceramic powder which accounts for 10-30% of the mass of the domestic ceramic blank, conducting mixing to obtain far-infrared emission ceramic glaze slip, adding the far-infrared emission ceramic glaze slip, ballstone and water into a ball milling tank according to a mass ratio of 1:2.5:1, carrying out ball milling, and conducting sieving with a 100-mesh porous sieve to obtain far-infrared emission ceramic slurry; uniformly smearing the prepared far-infrared emission ceramic slurry on the surface of a ceramic green body accordingto a daily ceramic glazing process to serve as daily ceramic ground glaze, and then putting the coated ceramic green body into a drying furnace to be dried to obtain a ceramic green body coated with far-infrared emission mixed powder; and carrying out surface glaze decoration on the surface of the prepared ceramic blank body, conducting drying, putting the decorated ceramic blank body into a domestic ceramic firing furnace, conducting heating at a heating rate of 5 DEG C / min, conducting heating from room temperature to a temperature of lower than 1250 DEG C, keeping the temperature for 1 hourto 2 hours, and conducting natural cooling to room temperature to obtain the high-emissivity far-infrared domestic ceramic.

Description

technical field [0001] The invention relates to the field of far-infrared emitting daily-use ceramics, in particular to a preparation method of high-emissivity far-infrared emitting daily-use ceramics. Background technique [0002] Far-infrared emitting household ceramics can emit more far-infrared energy than normal ceramics. Far-infrared energy not only has an activation effect on food, beverages and water, but also has health care functions on the human body. It can promote human metabolism, accelerate the decomposition of lactic acid, eliminate Fatigue, improve human immunity and other functions. [0003] Usually far-infrared emitting ceramics are prepared by mixing far-infrared ceramic powder with ceramic glaze slurry, glazing and firing at high temperature to obtain functional ceramic materials with far-infrared emission. The Chinese patent application document with the publication number CN1141265A discloses a far-infrared ceramic glaze, which is a functional ceramic...
