Description
Technical field
The invention belongs to ceramic technology field, specially a kind of ceramic glaze and preparation method thereof.
Background technique
Ceramics are the general names of pottery and porcelain, and ceramic art is play an important role always in magnificent culture and arts.People
Neolithic Age before about 8000 just invented pottery.In addition to being used in feeder, on decoration other than, ceramics science,
Key player is also play in the development of technology.Ceramic raw material is that the original vast resources clay of the earth takes by quenching.And
The property of clay has toughness, and room temperature chance water is plastic, and micro- do can carve, absolutely dry to grind；Ceramic material be mostly oxide, nitride,
Boride and carbide etc..Currently, domestic ceramics has been essential life porcelain in people's daily life.And for pottery
Porcelain art for, glaze therein again be and its key a part.Usually, so-called ceramic glaze is that one kind is coated on
The uniform glassy thin layer on ceramic idiosome surface.For ceramic, ceramic glaze can improve service performance, play dress
Decorations effect.
Chinese invention patent CN103408328A discloses a kind of ceramic glaze, each component including following parts by weight: long

It is taken out after 80min, crosses 200 meshes, filters pressing, aging 15 days at 30 DEG C, product mud is made；
Step S4, product mud obtained in step S3 is rolled over ceramic idiosome surface, is transferred in Muffle furnace later 380
DEG C temperature lower calcination 3h takes out and Muffle furnace is simultaneously warming up to 850 DEG C, stands to be put into 850 DEG C of Muffle furnaces after 30min and calcines 10h,
It is cooling, ceramic glaze is made.
Comparative example 3
This comparative example is a kind of ceramic glaze in market.
It can be into the corrosion resistance of embodiment 1-4 and comparative example the 1-3 ceramic glaze prepared, flatness, resistance to oily stain
Row test, test result is as follows shown in table 1；
Corrosion resistance: electrochemistry experiment method；
Flatness: selecting 6B pencil, pencil-lead be whittled into flat, streaked on glaze with pencil 10 times, observes glaze
Upper remaining trace；
Table 1
It can be seen that the ceramic glaze corrosion electric current density of embodiment 1-4 preparation is in (1.07-1.13) E-7 from upper table 1
(A/cm2) between, comparative example 1-3 is at (1.85-3.17)) E-7 (A/cm2) between；The ceramic glaze corrosion resistant of embodiment 1-4 preparation
Efficiency is lost in 98.7-99.2 (%) range, and comparative example 1-3 is in 62.3-80.1 (%) range；The pottery of embodiment 1-2 preparation
Trace is shallower after glaze streaks 10 times with pencil, embodiment 3-4 streak 10 times with pencil after without trace, comparative example 2-3 lead
Trace is obvious after stroke crosses 10 times；So ceramic glaze prepared by the present invention has good corrosion resistance, and flatness
Preferably.
