Abstract
A multi-colour artificial cobble is prepared from clay, porcelain stone, kaolinite, clinker, feldspar, quartz, talc and pigment through making cobble blank with the first three, preparing enamel from others, applying enamel to the cobble blank and sintering. Its advantages are high compression strength (58MPa or more), high resistance to acid and alkali, low hydroscopicity, high antiwear nature, beautiful appearance and low cost.
Description
The present invention relates to a kind of multi-colour artificial cobble and preparation method thereof.
The harmony of the Nature is the human target of pursuing.In world today's building construction or the construction of path, gardens, with natural cobblestone build a wall, surfacing or ground, give the impression that goes back to nature with high-grade decoration, the pedestrian walks on Shi Lu barefoot can also stimulate Pelma acupuncture points, has the effect of massaging and body-building.If can solve the deficiency of some existence, the application of pebbles will be more extensive.At first be the natural cobblestone resource-constrained, so that cost is higher, the destruction that a large amount of collections certainly will cause ecotope; Next is that natural cobblestone is not of uniform size, became uneven, surface irregularity, give construction and barefoot walking has brought inconvenience; Be that the natural cobblestone color and luster is single once more, it is identical easily to piece together the pattern, the decorative effect that manifest.By literature search, find no the relevant report of multi-colour artificial cobble, the disclosure of artificial colored stone technical scheme is only arranged, a kind of " artificial glazed stone and production technique thereof " disclosed as Chinese patent 1063473, this artificial glazed stone is to be raw material with pottery, glass, cement, and it is painted to add paint, dyestuff, light-shielding agent etc., is stirred into groove, airing the rostone flat-sheet material, comparable with marble or ornamental brick.Because it is condensed into non-pebbles type, ultimate compression strength, acid and alkali-resistance and wear resisting property all can not contend with lithotome, and color easily takes off and die, and only can be used for decorations such as indoor wall.
The purpose of this invention is to provide a kind of stone matter and natural cobblestone is low near cost, specification is consistent and appearance luster is beautiful artificial cobble.
The objective of the invention is to realize in the following way:
Multi-colour artificial cobble comprises the component (a) that constitutes the stone base and constitutes outer overglaze component (b).Component (a) is selected clay, china clay, three kinds of raw materials of kaolin for use, good because of clay viscosity, be convenient to that moulding, sintering temperature are low, low price selects it, china clay sintering whiteness and hardness are high and select it, higher hardness is arranged behind the kaolin sintering, can brighten, price is lower and select it.If the clay proportional quantity for a long time, finished product is crisp and contraction ratio is big, and the kaolin proportional quantity for a long time, sintering temperature will raise, energy consumption strengthens, thereby cooperate by weight percentage, can be clay 5～30, china clay 40～70, kaolin 25～45, be preferably clay 8～15, china clay 50～60, kaolin 30～40.Component (b) is selected frit, feldspar, quartzy, kaolin, talcum and pigment additive are raw material, because of frit can strengthen avidity and glaze luminance brightness with the stone base, feldspar can strengthen hardness of glaze surface and luminance brightness, quartz can strengthen hardness of glaze surface and toughness, kaolin and talcum are stopping composition, the pigment additive is regulated glaze color or the like, so select it, cooperate by weight percentage, can be frit 23～28, feldspar 25～29, quartzy 23～28, kaolin 8～13, talcum 8～13, pigment additive 1～10 is preferably frit 24～26, feldspar 26～28, quartzy 23～25, kaolin 8～10, talcum 8～10, pigment additive 1～6.The weight percent that component (b) accounts for component (a) and component (b) gross weight is 0～15, is preferably 0～7, and this is because of component (b) proportional quantity for a long time, even repeatedly glazing can not be used up, if when component (b) was zero, the stone base still was single oyster white, a kind of color of also can yet be regarded as.Pigment additive in the glaze component (b) can be cobalt oxide, zirconium indigo plant, the colour of loess or its combination, adjusts to be varied to different colors.
The preparation method of multi-colour artificial cobble, be included in the ceramic technology field well-known blank technical process and be batching, pulverizing, washing, filtration, precipitation, press filt, stirring particulate, thereafter be squeezed into egg type or oblate pebbles just base, again drying and glazing, sintering, anneal, come out of the stove.Sintering eventually temperature is bigger to the finished product influence with the time, and sintering is warm eventually when on the low side, and sintering is immature, show that finished product is loose, glaze is brightless, the whole Wen Taigao of sintering is, finished product excessive shrinkage and energy consumption are big, and sintering time length also can produce these problems under the whole temperature of same sintering.So the whole temperature of sintering can be 1000～1600 ℃, 8～12 minutes whole temperature control time.Multi-colour artificial cobble can form different glaze color, striped or pattern under different sintering temperatures.The glazing technology flow process also should be known to the ceramic technology those skilled in the art, promptly prepare burden, wash stirring, coarse filtration, adding pigment additive, ball milling mixing, fine filtering, glazing, glazing can be sprayed glaze liquid with spray gun to stone base top and side face, the stickup during towards the then more convenient construction of ground not glazing of one side of stone base.
The present invention forms stone matter hard (more than the pressure resistance 58Mpa), wear resistant corrosion resistant because adopt clay, china clay and kaolin to prepare pebbles through high temperature sintering.(resistance to acids and bases reaches the GAL level, average water-intake rate is 0.4%), cost low (50 yuan every square metre).So stone matter and natural cobblestone are approaching, price approximately cheap half, can substitute natural cobblestone fully; Simultaneously because the strong prescription glaze of avidity is sprayed on stone base surface, glaze can form distinct colors, striped and pattern under different sintering temperatures, exactly likes natural " Yuhua stone ", and will never fade, so overcome the single deficiency of natural cobblestone color and luster, indoor and outdoor all can be used; In addition because the imitative natural cobblestone of base moulding just, its size, thickness, specification are more unified, and institute is so that packing, transportation and construction, thereby have reduced comprehensive cost significantly, or the like.
Other details of the present invention can be derived from following subordinate list and embodiment
Table 1 is that the pebbles stone base set of dispense that proposes according to the present invention is than embodiment and effect comparison thereof.
Table 2 is that the pebbles glaze set of dispense that proposes according to the present invention is than embodiment and effect comparison thereof.
