Description
Technical field
The present invention relates to a kind of light foamed ceramic decorative tile and manufacture method thereof, belong to the light ceramics category.
Technical background
Play the building earthenware brick of decoration function because proportion (is generally 2.2-2.6g/cm greatly
3), the brick face adopts goes up " glaze " or " polishing " processing, must paste firmly with sand-cement slurry during use,, be usually used in the decoration of exterior wall by professional's constructing operation, be used for the indoor wall decoration if will build earthenware brick, the vitreous luster of the monotone of glaze and polishing then, make indoor decorative effect seem magnificent excessively, elegance and deficient change, and the bigger building earthenware brick of proportion has increased body of wall and has born, it is dangerous to come off easily, and construction is very inconvenience also.In recent years, some light foamed ceramics have appearred on the market, because its light weight, can effectively alleviate the load-bearing of body of wall, also be beneficial to safe construction, point out the alternative materials for wall of foamed ceramic, interior exterior wall and ground, top ceiling decorative block as " application prospect of high temperature foamed ceramic " delivered in " pottery " 94,1.Light foamed ceramic, have plenty of with low temperature (below the 250 ℃) shaping of hardening, have plenty of with high temperature (more than 700 ℃) and burn till, notification number is that 1147489 patent documentation " a kind of light foamed ceramic and manufacture method thereof " just belongs to the latter, this pottery comprises four kinds of compounds, it is inflatable to meet heat, with the acid silicon dioxide is the volcanics of principal constituent, the alkaline including earth metal type oxide, the compound that carbonate etc. are formed, the inorganic bonding agent of alkali metal containing class, the foamed promoter that contains silicates, call in an amount of water in addition, expand through raw material, batch mixing, grind, oven dry, pulverize, moulding, processes such as sintering obtain product, it is easy to make foamed ceramic with this kind method, but directly make regular ceramic tile difficulty, reason is uncontrollable foam degrees in sintering procedure, that is to say, can not make the light foamed ceramic brick of physical dimension unanimity in batches, in addition, the document only provides the application of described foamed ceramic in the lightweight aspect, do not mention the decoration that is used for body of wall etc., more do not mention the brick body and itself have ornamental.
Summary of the invention
The present invention is just in order to overcome above-mentioned deficiency, the concave-convex curved surface effect that provides a kind of outward appearance (body, color) to change to enrich, have lithotome, has very strong ornamental light foamed ceramic brick.
It is a kind of easy to operate and can control the manufacture method that the brick body burns till the above-mentioned light foamed ceramic brick of shape that second purpose of the present invention is to provide.
The realization of the present invention's first purpose is to adopt and adds a spot of whipping agent in ceramic batch, in the high-temperature firing process, whipping agent reacts with the ceramic batch of congruent melting mutually, produce a large amount of gases, under ceramic batch melts state in the beginning, expand because of the volatilization " promotion " of gas whole " foaming " in order, make blank become " lightweight ", the profile that it is regular and the effect of surface irregularity then come from the high-melting-point pottery mineral poor material particle of relative base-material fusing point.Specifically, a kind of light foamed ceramic decorative tile is the burned material that ceramic batch, whipping agent, skeleton material all mix the thing stampings, it is characterized in that ceramic batch and whipping agent constitute the fine powder base-material of decorative block, wherein whipping agent weight accounts for 1-7%, and all the other are ceramic batch; The skeleton material is to be higher than the relative high-melting-point pottery mineral poor material particle of base-material fusing point or by relative high-melting-point pottery mineral poor material particle and/relative low melting point pottery mineral poor material grains of composition of conforming to close with the base-material fusing point, the content of described skeleton material is the 20-50% of base-material weight.If change a kind of metering method, promptly make benchmark for 100 parts in base-material and skeleton material, decorative block then is mixed by the base-material of the skeleton material of 15-35% (weight percent) and 65-85% (weight percent).In this programme, the firing temperature of foamed bricks is decided to be 1150-1250 ℃, according to firing temperature, select feldspar, porcelain stone class low temperature feedstock is the batching of ceramic batch, through debugging, feldspar with 30-50% (weight percent), the clay of 20-40% (weight percent) is that the ceramic batch of main body is more suitable, because feldspar is flux and cheap conventional ceramic raw material, clay is then given the moulding plasticity of blank certain high temperature viscosity and material, with feldspar, clay is a major ingredient, auxiliary material (or clout) is generally quartz, can be the beginning molten state at the ceramic batch under this proportioning under 1150-1250 ℃.Under the high temperature, the mutual congruent melting of whipping agent in the base-material fine powder and ceramic batch, vigorous reaction, generate a large amount of volatile gaseses, because the high viscosity character of ceramic batch, " overflowing " of gas cause outwards slowly expansion in order of blank, after cooling, brick body inside presents intensive closed pore structure, thereby reaches " lightweight ".The material that plays foaming effect can use silicon carbide, powdered carbon, ferric oxide, fluoridize mineral material etc., but from being the bubble homogeneity, the influence and the reduction firing temperature of brick tire look being considered, makes whipping agent the best with silicon carbide and the composition of fluoridizing the mineral material.Silicon carbide does not present uniform in foaming, introducing amount less, the tire look is not had the advantage of obvious influence, from foaming effect and cost consideration thereof, its amount in base-material to account for 0.1-0.8% (weight percent) for good; Fluoridize in the mineral material fluorine at high temperature " burning " emit a large amount of volatile gaseses, it is similar that it is bubble effect and silicon carbide, but the most important is to fluoridize that the mineral material has cold service and effect is remarkable, promptly in ceramic batch, introduce and fluoridize the mineral material, the beginning that can reduce material is greatly melted temperature, realize that material begins to melt at a lower temperature, foaming, simultaneously, owing to fluoridize " cold service " of mineral material, clay ratio in also can corresponding increase ceramic batch, to improving the plasticity of blank, the intensity that strengthens the base brick is useful, fluoridize mineral material addition what be inversely proportional to the firing temperature of blank, relatively the consumption of Shi Heing is 1-6% (weight percent in base-material), through test, do fluoridizing the mineral material Sodium Silicofluoride can being arranged of whipping agent, Sodium Fluoride, Calcium Fluoride (Fluorspan) or the like can be selected one or more combination wherein in this programme.In order to control the swell increment of ceramic batch in sintering process, control brick shape, this programme high-melting-point pottery mineral poor material particle with relative base-material fusing point is made the skeleton material, can improve the expansion effect of material.Because at high temperature; dystectic relatively skeleton material because of its fusing point than the ceramic batch height; so be the beginning during fusion at ceramic batch; the skeleton material is still ont yet molten; it freely is distributed in the ceramic batch that is under the molten state; be subjected to the influence of its gravity; the skeleton material constitutes the resistance that volatile gases expands outwardly; simultaneously; coarse particles has also stoped the mutual merging between bubble, has suppressed fusion blank inside and has formed air pocket, guarantees that bubble is slowly outwards expansion in order; thereby reach the effect of control swell increment, what cooled brick body inside formed is intensive closed pore.In this programme, preferable with 30-80 order effect as the coarse particles of skeleton material, addition is generally the 20-50% of base-material weight, and very few skeleton material causes that easily the brick body deformability is serious, crosses can cause surface irregularity at most.For fear of skeleton material and base-material base substrate disconnection is arranged after burning till, therefore constitute in the coarse particles of skeleton material and also contain relative low-melting ceramic mineral poor material such as the hard feldspar that conforms to the base-material fusing point, the porcelain stone class, be referred to as relative low melting point, be meant that it compares with the high-melting-point of the quartzy class that is higher than base-material fusing point pottery mineral poor material, its fusing point is lower, generally close or conform to the melt temperature of base-material, like this, at high temperature, coarse particles as the skeleton material is not all not fusions, but full-fusing not, its fusion partly can combine together with base-material, and the part of full-fusing is not distributed in the brick body in picturesque disorderly, certainly also comprise the brick surface after the expansion, it has strengthened the uneven of brick surface, makes it to compare with " traditional brick ", and surface effect has more the coarse naturally aesthetic feeling of lithotome section.Relative low melting point pottery mineral poor material in the skeleton material is good with relative dystectic ceramic mineral poor material more than 10% with what respectively account for base-material weight.
The realization of the present invention's second purpose is the above-mentioned ceramic batch that is finely powdered and whipping agent and coarse particles skeleton material are mixed by proportioning, and a dry-pressing makes work in-process, work in-process under firing temperature, fire finished product.
As required, can spray the monochromatic or pleochroic thin mill base of one deck on the work in-process after dry-pressing formed.Because each opposite sex on material expands in inside, chromatograph colour generation on the surface after the expansion is deep mixed, is full of variety, and has increased the peculiar aesthetic feeling of foamed bricks.
The light foamed ceramic decorative tile that the present invention sets forth forms through high temperature foaming growth, concave-convex curved surface effect with lithotome, simultaneously, the colored brick of additive color also can satisfy people's different aesthetic requirements, have very strong ornamental, the manufacture method of burning till after the once shaped, easy, production cost is low, and the brick shape that burns till is unified.
