Abstract

This invention discloses a technique for producing ceramic polished bricks. The raw materials comprise: high-whiteness ultra-fine quartz powder 45-60 wt.%, feldspar flux 15-35 wt.%, clay 5-20 wt.%, Ca-Mg raw material 0-8 wt.%, and strengthening agent 0.1-1 wt.%. The method comprises: preparing the raw materials, ball-milling, sieving, removing Fe, spray-drying to obtain powder, aging, pressing, drying, sintering, polishing, and screening. The introduction of large amounts of quartz, feldspar flux and strengthening agent can reduce the consumption of clay, and improve the whiteness and light permeability of the ceramic polished bricks. The ceramic polished bricks have such advantages as high whiteness, no radioactivity, high light permeability and good appearance.

Description

A kind of polished brick in porcelain character and manufacture craft thereof
Technical field:
The present invention relates to technical field of construction and decoration materials, refer in particular to a kind of polished brick in porcelain character and manufacture craft thereof of high quartz content.
Background technology
At present polished brick in porcelain character generally is non-plastic raw materials such as potassium felspar sand, albite, porcelain stone, black talc are mixed by a certain percentage with clay class plastic material and to be milled to certain fineness by ball mill, burns till through spray pulverization, compression moulding, drying again.Its chemical constitution is roughly: SiO 264%~73%, Al 2O 315%~22%, Fe 2O 3IO20.5~2%, CaO+MgO0.5%~3%, K 2O+Na 2O 3%~6%.Owing to contain higher Al 2O3, Fe 2O 3And TiO 2Deng coloring components, existing polished brick in porcelain character ubiquity whiteness is poor, and light transmission is poor, disadvantages affect such as beautiful texture difference the decorative effect of polished tile.Can't satisfy the demand of people to the GOOD TASTE polished tile.
Summary of the invention:
The objective of the invention is to overcome the deficiencies in the prior art part, polished brick in porcelain character that a kind of whiteness height is "dead", the good beautiful texture of light transmission is strong and preparation method thereof is provided.
To achieve these goals, technical scheme provided by the invention is: raw material mainly is made up of the component of following ratio: high white superfine silica powder 45~60%, feldspar flux 15~35%, one of clay raw materials 5~20%, calcium magnesia raw material 0~8%.The base substrate chemical composition is: SiO 273%~80%, Al 2O 38%~15%, Fe 2O 3+ TiO 2<0.6%, CaO+MgO 0.5%~4%, K 2O+Na 2O 2%~6%.
Feldspar flux of the present invention can be the one or more combination of nepheline syenite, albite or potassium felspar sand.Calcium magnesia raw material can be the one or more combination of wollastonite, burning talcum, rhombspar or calcite.The base substrate toughener can be the one or more combination of polyvinyl alcohol, Xylo-Mucine or modified lignin resin.
Described polished brick in porcelain character manufacture craft process is: batching-ball milling-sieve-deironing-spraying drying powder process-old-compression moulding-drying-burn till-polish-assortment.It is characterized in that: high white superfine silica powder 10~30 μ m particles of employing account for more than 50%, are no more than 10% less than 10 μ m, do not have greater than 100 μ m granule formulations; 0.5% fineness of blank ball milling to 10000-hole sieve will being surplused in the ball-milling technology is below the mark; In deferrization process, strengthen deironing 2~3 times; In firing process the proper extension clinkering zone for the previous period (15~30 minutes) to promote the eliminating of degradation production in the base substrate, to promote quartzy fusion, quartzy 573 ℃ crystal conversions near carry out slow cooling (10~30 minute) during cooling in high temperature firing zone proper extension soaking time (15~40 minutes).
The present invention is to be main raw material with the high white superfine quartz, painted Fe in the quartz 2O 3And TiO 2Content is very low, so the increase of quartz content can make the whiteness of base substrate be significantly improved in the base substrate.By selected feldspar flux, and add the intensity that special ceramic body toughener increases green compact, correspondingly reduce the addition of one of clay raw materials, improved the whiteness and the transparence of product.So have the advantages that the whiteness height is "dead", light transmission good, beautiful texture is strong after adopting the ceramic body of the present invention's preparation to burn till.
Embodiment:
The present invention is further illustrated below in conjunction with preferred embodiment:
Embodiment one:
1. raw material mainly is made up of the component of following part by weight: high white superfine silica powder 50%, nepheline syenite 15%, albite 20%, one of clay raw materials 12%, rhombspar 3%, modified lignin resin 0.5%, Xylo-Mucine 0.2%.
2. the making method of this polished brick in porcelain character: will prepare burden into ball mill by forklift in the starting material of above-mentioned requirements ratio prescription, and add the water of gross weight 45% and 0.5% water reducer water glass simultaneously to improve grinding efficiency.The ball milling fineness is controlled at 10000-hole sieve and tails over 0.2~0.5%.Mud through three roads repeatedly deironing sieve, guarantee to remove not levigated raw material and impurity iron.Spray-dried moisture 5~7% the powder that makes of gained mud.Grain composition is: greater than 30 orders 6~12%; 30~60 orders 〉=70; 60~80 orders≤12; Less than 80 orders≤5.This powder is passed through ceramic brick press compression moulding after old 24 hours, make the only remaining moisture below 0.5% of base substrate through 150 ℃~200 ℃ dryings.The dry tenacity of base substrate reaches 1.5~2.2Mpa like this, can stand glaze line operation and later process such as screen printing and decorate and do not split brick.Owing to introduced a certain amount of rhombspar and more base substrate toughener in the base substrate, its degradation production needs to carry out the liquid phase sintering front row at base substrate and removes, in order to avoid form pore.Prolong branch in the actually operating and ungird, and in the time of 950 ℃, be incubated 3 minutes to promote rhombspar to decompose.Contain more quartz in the base substrate, split brick, particularly when 573 ℃ of β quartz transition are the α quartz, be attended by 0.82% volumetric expansion because quartzy crystal conversion causes easily, destructive strong.So requirement heats up steadily near this temperature, quench zone carries out slow cooling, and the high-temperature zone adopts 1210~1240 ℃ of high temperature to burn the quartzy fusion of promotion, firing time 85 minutes slowly simultaneously.The gained sintered compact promptly gets product through polishing.
Embodiment two:
1. raw material mainly is made up of the component of following ratio: high white superfine silica powder 55%, nepheline syenite 25%, albite 5%, one of clay raw materials 12%, calcite 3%, polyvinyl alcohol 0.3%, Xylo-Mucine 0.1%.
2. the making method of this polished brick in porcelain character: be that with embodiment one difference base substrate after drying oozes fancy glaze (as add 2% high sticking Xylo-Mucine thickening in 10% sodium dichromate solution what its surface printing contained soluble salt solution earlier, form paste), be penetrated into base substrate in certain depth by soluble salt with water at an amount of infiltration water of brick surface spray, enter kiln then and burn till.
