Abstract

The present invention relates to a glass mosaic and a wall and floor tile prepared with pearlite tailings. The present invention is characterized in that waste tailings are used as principal raw material, and a plurality of kinds of auxiliary material are added; the present invention has the mixing ratio: 10 to 100 portions of tailing, 0 to 35 portions of calcite, 5 to 15 portions of sodium carbonate, 1 to 10 portions of sodium nitrate, 2 to 15 portions of sodium fluoride, 5 to 20 portions of derbyshire spar and 0 to 25 portions of high silicon bentonitic clay. The present invention makes the best of waste, the material cost per square meter is averagely reduced by 1.5 yuan than that of using silica sand raw material. Each technical index of the product accords with the national standard, the waste tailings can be used for manufacturing various painted glass mosaics, wall and floor tiles, glazed tiles and glassware.

Description

Glass tile for wall and floor with the pearlite tail sand making

The present invention relates to series product such as a kind of stained glass mosaic, glass tile for wall and floor, glaze face wall floor tile, glassware with the pearlite tail sand making.

Perlite powder is commonly used to make lagging material at present, and in shattering process, there is the by product of a large amount of 70～120 order granularities to claim pearlite tail sand (hereinafter to be referred as tailings) discarded, or is pushed into the river, or occupy the arable land, be important environomental pollution source.Traditional production glass-ceramic matter mosaic, the batching of wall floor tile are mainly with high silicon content (Sio ₂Nearly more than 90%) silica sand be main raw material, but because the silica sand composition is single, can not satisfies and fire the product physicochemical property and the index that reach of needs in use, so will add the various compounds that improve product performance, so just increased raw materials cost; Also have in recent years with cullet, useless silicates grog such as waste ceramic is a raw material, pulverizing the back mixes mutually by certain component proportioning, compression molding then, be fired into the reported in literature of mosaic and various face bricks, as No. 90104449.0, publication number is that the CN1057246A patent application promptly belongs to this situation, but this fires intensity and still people's satisfaction in addition of suitability of product; The CN1066210A name is called " pearlstone--low-temp ceramics colour glaze composite wall tile " patent application, is to adopt sintering such as multiple material preparation such as pearlstone, haydite or slag, waste broken glass bits and colored enamel etc.; So far do not see the relevant reported in literature that utilizes the discarded tailings of perlite to make mosaic and wall floor tile as yet.

The objective of the invention is to utilize the depleted pearlite tail sand to be main raw material, and the composition and the consumption of the auxiliary compound of minimizing, the higher supplementary product consumption of cost particularly, utilize existing installation and sintering technology, make a kind of use properties and reach or be better than glass Mosaic and the wall floor tile series product that the silica sand series raw material is fired.

The Chemical Composition of pearlite tail sand is analyzed as follows: (%)

SiO ₂ AL ₂O ₃?Fe ₂O ₃ FeO TiO ₂ CaO MgO

72.75 14.12 0.88 0.35 0.12 0.65 0.32

K ₂O Na ₂O igloss

7.5 2.7 0.84

According to above-mentioned analysis to the tailings composition as can be known; it contains formation agent, fusing assistant and intermediate agents such as making the required framework material silicon of glassiness product, potassium, sodium, aluminium, magnesium; do not adding any material through 900～1500 ℃ of basic vitreous of high temperature melting, be grayish green and blue green.Characteristics of the present invention are to replace silica sand as main raw material with the depleted pearlite tail sand, select adding calcite, high silicon wilkinite, soda ash, SODIUMNITRATE, Sodium Fluoride, fluorite auxiliary material to adjust again, feed intake according to certain proportioning, in 900～1500 ℃ of following fusions calendering formation again, formula constituent (by weight) is:

10～100 parts of pearlite tail sands

5～15 parts of soda ash

1～10 part of SODIUMNITRATE

2～15 parts of Sodium Fluorides

5～20 parts in fluorite

0～35 part in calcite

0～25 part of high silicon wilkinite

Proportioning raw materials of the present invention can be selected (by weight) for use

40～100 parts of pearlite tail sands

7～15 parts of soda ash

1～7 part of SODIUMNITRATE

2～15 parts of Sodium Fluorides

5～15 parts in fluorite

10～35 parts of high silicon wilkinites

10～25 parts in calcite

Owing to contain small amount of Fe in the tailings ₂O ₃Make product painted with FeO, had a strong impact on transparency of products,, introduced an amount of SODIUMNITRATE oxygenant in the present invention's prescription, make the Fe in the raw material in order to reduce iron level ₂O ₃All the time be in oxidation state and be not reduced into FeO, the FeO in the raw material is oxidized to Fe ₂O ₃, because the tinting strength of FeO compares Fe ₂O ₃Big tens of times, after FeO was oxidized, the coloring degree of product significantly reduced.If tailings is handled through iron removal by magnetic separation before use, the high silicon wilkinite of the skeleton raw material in the batching can all adopt pearlite tail sand to replace, and can also reduce or remove simultaneously the consumption of calcite.Because the effect of fluorochemical in the batching, can make FeO be converted into evaporable FeF or colourless NaFeF double salt, FeO is further suppressed, fluorochemical is as a kind of accelerator, not only can assist the oxygenant SODIUMNITRATE with the ferric oxide oxidation, can also reduce glass metal viscosity in the process of founding, improve molecular diffusion speed, the reaction process that vitreum is formed is quickened.Remain the iron of residual amount, high silicon wilkinite and fluorochemical by adding has the milkiness characteristic make product reach good opacity, to eliminate the coloration effects of iron to product.Different colours needs according to product can add an amount of pigment in founding, and its weight proportion is: total charging capacity: pigment=100: 0.1-15.The product specification of making according to said ratio is: length * wide * thick=20～100mm * 20～100mm * 3～8mm.

The present invention compares with existing like product has following advantage:

1, made full use of discarded tailings, controlled the environomental pollution source that causes thus, owing to reduced auxiliary material composition and consumption, every m ₂Raw materials cost has on average reduced by 1.5 yuan than the original silica sand raw material that adopts, and only the soda ash consumption has just reduced nearly 10% than original;

2, the product of the present invention trial-production, examining report that is provided by China Building Materials Academy and relevant user try out and show: indexs such as acidproof, the anti-cash of product, thermostability, appearance color, freeze-thaw-ability all meet the quality standard of national regulation;

3, product of the present invention is because water-intake rate is low, thermal expansivity is little, be not subjected to the weather condition effect, avoided existing ceramic matrix face brick because the phenomenon that suction is peeled off after freezing, be particularly suitable for northern cold or humid area and use, adopt raw material of the present invention can make various stained glass mosaics, glass tile for wall and floor, glaze face wall floor tile and glassware.
