Description
Technical field
The present invention relates to ceramic cooker technical field, particularly relate to a kind of high-performance low bulk and to hold concurrently function far infrared radiation function heat-proof purple sand cooker and preparation method thereof.
Background technology
Boccaro is a kind of stoneware, is a kind of ceramic between pottery and porcelain, and be characterized in compact structure, comparatively large close to porcelain, intensity, particle is tiny, fracture is conchoidal or stone shape, but does not have the translucency of porcelain body; Different from common greenwave, boccaro has dual air hole structure.As traditional daily necessities, boccaro has far-infrared radiation, acid-alkali-corrosive-resisting, the advantage such as nontoxic.Boccaro ware surface has chiltern and matt effect, and quality is simple and unsophisticated mellow, has high artistry and sight all the time.Based on the characteristic of purple sand pug and the limitation of technology, boccaro ware from ancient times to the present its traditional function is as drinking vessel, and the tea set of namely making tea uses; At present, in life, be also typically used as the cooking utensils and tableware such as saucepan, steamer, but be not suitable for being directly used in open firing.
Along with improving constantly of expanding economy and living standards of the people, people are also more and more higher for the requirement of boccaro ware, and traditional boccaro ware also exists impact resistance difference and the shortcoming such as thermal shock resistance is low, and folding strength is 10 ~ 30MPa, thermostability only has 180 DEG C ~ 20 DEG C, can not open firing.Now, human consumer requires boccaro ware can be used for decocting Chinese medicine by boiling and simmering, Baoshang, boil the hopes such as tea, and traditional boccaro ware can not meet.And easy-formation, cracky, production qualification rate are not low in the mill; The intensity of product is lower, because collision is easy to cause breakage in transportation loading and unloading process, is thus difficult to the user demand meeting consumption market.For this reason, scholar is studied improvement to traditional boccaro ware in the industry, such as, by adding triphane or preparation formation cordierite boccaro etc., to reduce the purple clay coefficient of expansion, thus realizes the raising of thermal shock resistance.But the gained coefficient of expansion is still higher, easily ftractures, use dangerous; And cordierite material firing range is narrow, thermostability fluctuation is comparatively large, and yield rate is low.Generally speaking, prior art still can not solve the technical problem existing for traditional boccaro ware well, has become the bottleneck of boccaro ware enterprise development, is difficult to the demand meeting development and the market application of producing.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, there is provided that a kind of thermal shock resistance is good, intensity is high, cost is low and there is the high performance heat resistant purple stoneware cooking ware of function far infrared radiation function, meet boccaro ware as daily living article use while, improve the performances such as the intensity of product, shaping and far infrared, to meet safety in utilization and the health-caring function of human consumer well, thus be conducive to the technical progress and the application development that promote purple stoneware cooking ware industry.Another object of the present invention is to provide above-mentioned high-performance low bulk to hold concurrently the preparation method of function far infrared radiation function heat-proof purple sand cooker.
Object of the present invention is achieved by the following technical programs:
A kind of high-performance low bulk provided by the invention is held concurrently function far infrared radiation function heat-proof purple sand cooker, is made up of base substrate base-material and base substrate additive; Described base substrate base-material consist of purple clay 45 ~ 57wt%, lithium feldspar 28 ~ 40wt%, boccaro raw ore 5 ~ 10wt%, subnar soil 1 ~ 3wt%, black talc 5 ~ 9wt%, wilkinite 0.5 ~ 1.5wt%, rare earth tailings 1 ~ 3wt%, alumina powder 1 ~ 3wt%; Relative to base substrate base-material, described base substrate additive consist of negative ion far-infrared micro mist 10 ~ 15wt%, zirconium white micro mist 1 ~ 2wt%, yttrium oxide micro mist 0.5 ~ 1wt%.
Preferably, base substrate base-material of the present invention consist of purple clay 48 ~ 55wt%, lithium feldspar 30 ~ 38wt%, boccaro raw ore 5 ~ 10wt%, subnar soil 1 ~ 3wt%, black talc 5 ~ 7wt%, wilkinite 0.5 ~ 1.5wt%, rare earth tailings 1 ~ 3wt%, alumina powder 1 ~ 3wt%; Relative to base substrate base-material, described base substrate additive consist of negative ion far-infrared micro mist 12 ~ 15wt%, zirconium white micro mist 1 ~ 2wt%, yttrium oxide micro mist 0.5 ~ 1wt%.
The present invention introduces expansion ceramic material lithium feldspar in blank, while reducing parison swell coefficient, improving its thermostability, can promote the sintering character of blank, be conducive to improving its intensity.In addition, by adding negative ion far-infrared micro mist, contribute to improving boccaro ware far infrared transmission power, can activated water, make taste of food more delicious, can not beneficiating ingredient be destroyed.By additional rare earth material yttrium oxide and rare earth tailings, the sintering reaction of base substrate can be promoted, improve the intensity of product.Using zirconium white, aluminum oxide as toughen and intensify material in blank, contribute to the shock resistance improving base substrate.
Further, the fineness of alumina powder of the present invention, negative ion far-infrared micro mist, zirconium white micro mist, yttrium oxide micro mist is 1 ~ 20 μm, is preferably 5 ~ 15 μm.
Another object of the present invention is achieved by the following technical programs:
The hold concurrently preparation method of function far infrared radiation function heat-proof purple sand cooker of above-mentioned high-performance low bulk provided by the invention is as follows: after described base substrate base-material and the mixing of base substrate additive formulations, carry out ball milling, sieve, filter-press dehydration and obtain blank, then by described blank vacuum pugging, shaping, dry, the slow firing technique of oxydizing flame is adopted to burn till afterwards, namely burn to 1200 ~ 1250 DEG C from Oxidation at room temperature atmosphere slowly through 8 ~ 9.5h, obtain high-performance low bulk and to hold concurrently function far infrared radiation function heat-proof purple sand cooker product.
Further, the ball milling of base substrate base-material and base substrate additive described in preparation method of the present invention adopts segmentation ball milling, and namely base substrate base-material first carries out one section of ball milling 7.5 ~ 8.5h, and then adds base substrate additive and carry out two sections of ball milling 2 ~ 3h together.
