Abstract

The invention discloses a production method of a lightweight heat-resistant ceramic. The production method comprises the following production steps: (1) preparing diatomite, pyroxene diorite, dickite, rectorite and wavellite into petuntse for later use; (2) crushing a timber to prepare wood powder, and then mixing the wood powder and the petuntse uniformly to prepare wood powder mud for later use; (3) adding water into the petuntse to blend slurry for later use; (4) molding the wood powder mud into a blank, then heating the blank to 350 DEG C first for firing for 15min in a kiln, then cooling the blank to a normal temperature, and then taking out the blank and soaking the blank in the slurry; and (5) taking out the blank after adsorption of the slurry, putting the blank on a sponge block, then naturally drying the blank in a ventilation place, and then firing the blank for 8 hours at 1230 DEG C in the kiln to prepare a product. The heat-resistant ceramic product prepared by the method disclosed by the invention can resist heat exchange between 650 DEG C and 20 DEG C without cracking, is lighter in weight compared with a conventional heat-resistant ceramic product, and has a certain heat preservation effect.

Description

The production method of light heat-resisting ceramics
Technical field
The present invention relates to ceramic field, specifically a kind of production method of light heat-resisting ceramics.
Background technology
Burnt till because ceramic cooker have passed through high temperature, use safety and environmental protection, ceramic cooker has been obtained largely in recent years Use, because traditional heat-stable ceramic product is substantially to obtain heat resistance by adding substantial amounts of spodumene, its product is former Material source is single, limits the production of product.And heat-stable ceramic cooker is due to hand-held, product weight is overweight to be influenceed to make With.
The content of the invention
To solve the above problems, the invention provides a kind of production method of light heat-resisting ceramics.
The production method of light heat-resisting ceramics of the present invention, it is characterised in that including following production stage：
（1）Take the weight portion of diatomite 10, the weight portion of augite diorite 20, the weight portion of dickite 15, the weight portion of rectorite 22, silver-colored star The weight portion of stone 10, mixing adds water and cross after ball milling that to be made porcelain mud standby for 325 mesh sieves；
（2）Take and crossed after timber is crushed the prepared wood powder of 325 mesh sieves, then take the weight portion of wood powder 5 and mix with the above-mentioned weight portion of porcelain mud 100 Uniformly, it is made wood powder mud standby（Weight portion and step in this step（1）In weight portion it is different）；
（3）Take above-mentioned porcelain mud and add water that to be deployed into the mud that concentration is 20 Baume degrees standby；
（4）After being base substrate through dehydration, pressure mud, old, mud refining, injection forming by traditional handicraft by above-mentioned wood powder mud, base substrate is put First be warming up in kiln 350 DEG C burn till 15 minutes after, then be cooled to normal temperature, then base substrate is taken out and is immersed in above-mentioned mud 3-5 seconds, billet surface is set to adsorb mud；
（5）The base substrate that mud will be adsorbed is taken out, and is placed in 3-4 seconds on sponge block, and base substrate then is positioned over into ventilation nature Dry 24 hours；Then to be placed in kiln carried out in 1230 DEG C again and burn till 8 hours, be made product.
The heat-stable ceramic product that the present invention is made, is resistant to 650 DEG C~20 DEG C heat exchanges without splitting, and because wood powder is burning Burning forms hole during, and product weight is made compared with traditional heat-stable ceramic product light 3-5% with definitely insulation With；The composite can be widely applied to the production of the products such as ceramic cooker, electricity pottery stove ceramic package.
Specific embodiment
By the following examples and comparative example the present invention will be described in detail.
Embodiment：（1）Take the weight portion of diatomite 10, the weight portion of augite diorite 20, the weight portion of dickite 15, rectorite 22 Weight portion, the weight portion of wavellite 10, mixing add water and cross after ball milling that to be made porcelain mud standby for 325 mesh sieves；
（2）Take and crossed after timber is crushed the prepared wood powder of 325 mesh sieves, then take the weight portion of wood powder 5 and mix with the above-mentioned weight portion of porcelain mud 100 Uniformly, it is made wood powder mud standby（Weight portion and step in this step（1）In weight portion it is different）；
（3）Take above-mentioned porcelain mud and add water that to be deployed into the mud that concentration is 20 Baume degrees standby；
（4）After being pot parison body through dehydration, pressure mud, old, mud refining, injection forming by traditional handicraft by above-mentioned wood powder mud, by base Body be placed in kiln be first warming up to 350 DEG C burn till 15 minutes after, then be cooled to 30 DEG C, then base substrate is taken out and is immersed in above-mentioned mud 4 seconds in slurry, billet surface is set to adsorb mud；
（5）The base substrate that mud will be adsorbed takes out, and is placed in sponge block upper 4 second, base substrate then is positioned over into ventilation and is dried in the air naturally It is dry 24 hours；Then to be placed in kiln carried out in 1230 DEG C again and burn till 8 hours, be made the heat-stable ceramic pot of embodiment.
Comparative example 1：From unlike embodiment, diatomite is substituted with feldspar, the heat-stable ceramic pot of comparative example 1 is obtained.
