Description

A kind of shock resistance, high strength domestic ceramics

Technical field

The present invention relates to a kind of domestic ceramics, particularly a kind of shock resistance, high strength domestic ceramics, belong to domestic ceramics technical field.

Background technology

Domestic ceramics refers to life porcelain.As its name suggests, the generation of domestic ceramics can be described as because the demand of people to daily life produces, and in daily life, people contact at most, are also the most familiar porcelain, as tableware, tea set, coffee service, coffee set, drinking utensils, meal tool etc., closely bound up with the life of people.

Domestic ceramics has following advantage: the first, is easy to washing and keeps clean; The second, better heat stability, heat transfer is slow, the performance not easily burst when having the hot quenching change of the urgency standing a fixed difference difference, and is used for splendid attire boiling water or boiling hot food, not too hot when end is taken; 3rd, stable chemical nature is durable in use; 4th, the pore of porcelain is few, and water-intake rate is very low, stores food with domestic porcelain, after tight sealing, can prevent the infringement of moisture evaporation in food, infiltration and extraneous bacterium; Etc..Therefore domestic porcelain is for a long time by broad masses of the people are liked and use.

CN200510093273.6 discloses a kind of domestic ceramics and preparation method thereof, adopt and add a small amount of mineralizer on common raw material basis, and made by batching of the present invention, have Heat stability is good, transparency is high, and whiteness is high, glossiness is good, porcelain is fine and smooth, has the texture of similar beautiful matter, the advantage of closely true china from porcelain; CN201010261479.6 discloses a kind of domestic ceramics and the manufacture method thereof that fully utilize the production of multiple mine tailing, household ceramic blank is made up of following weight percent raw material: the native mine tailing 18 ~ 20 in clear hole, Guo Dong porcelain clay tailings 15 ~ 17, nest, soil Kaolin Tailings 19 ~ 22, feldspar 16 ~ 17, clay 24 ~ 27; CN201110423181.5 discloses a kind of microcrystalline domestic ceramic utilizing talcum to prepare, its feed composition and component concentration thereof with 100 grams of micro-crystalline ceramic carcasses be the quality of each component of benchmark gram to count: talcum: 55 ~ 65, albite: 50 ~ 65, potassium felspar sand: 4 ~ 15, barium carbonate: 0.2 ~ 1.8.The pottery that these patents provide, remains aesthetic feeling and the function of general domestic ceramics, but also has Shortcomings part, and greatest weakness is that resistance to impact shock is low, and resistance to falling is not touched, and easily damaged, be a kind of fragile article, this is also the ubiquitous problem of ceramic ware for daily use.

CN201410002619.6 discloses a kind of high-strength abrasion-proof ceramic ware for daily use containing Brown Alundum, this ceramic is made up of the raw material of following weight part: clay 50 ~ 55, Brown Alundum 10 ~ 15, cubic boron nitride 12 ~ 14, aluminium powder 1 ~ 2, copper powder 2 ~ 3, nickel powder 1 ~ 2, aluminium oxide powder 5 ~ 6, carbon black 2 ~ 3, ironic oxalate 1 ~ 2, Z 250 2 ~ 3, Silver Nitrate 1 ~ 2, alum 1 ~ 2, iron ore ground-slag 1 ~ 2, auxiliary agent 7 ~ 9, owing to the addition of Brown Alundum in this formula, the high strength such as cubic boron nitride, the raw material that wear resisting property is excellent, therefore improve the intensity and abrasion resistance properties that improve idiosome to a certain extent, ceramic is made to have excellent hardness and intensity, tensile strength is large.But the ceramic ware for daily use that this patent system obtains, more thick and heavy, therefore easily cause and use and carry inconvenience.For how to make domestic ceramics take into account aesthetic feeling, lightweight fine and smooth with shock resistance, characteristic that intensity is large, current technology does not also have effective solution.
