Description

Artificial cement marble and manufacture method thereof

The present invention relates to a kind of artificial marble and manufacture method thereof.

With the immediate prior art of the present invention be " Sichuan building materials " the 2nd phase in 1986 contained " production of inorganic mineral artificial marble ", introduced with special cement in this article and made method for imitation marble, but use this method to make artificial marble, because mill base and cement are poured into mould respectively, the cohesive strength of mill base and cement is affected, also influenced simultaneously the smooth finish of artificial marble surface, artificial marble with this method manufacturing, frost appears analysing easily, and need be through rumbling compound maintenance commonly used.

The objective of the invention is to overcome the existing above-mentioned weak point of the clay artificial marble of making of water, make production technique simple, surface smoothness height, surface are not analysed frost, not masked, product does not need with the rumbling compound maintenance and can make the surface keep higher smooth finish more for a long time.

The cement of manufacturing of the present invention is made marble and is made up of upper layer and base layer two portions, base layer is ordinary Portland cement mortar (or concrete) commonly used, also available high-alumina cement mortar, upper layer is aluminate cement and Portland blast, adding suitable pigment again mixes by a certain percentage through ball milling and makes granularity reach the 200-400 order, sand (as quartz sand, river sand) is joined in the compound behind the ball milling, add suitable quantity of water again and stir and become surface layer slurry.The moiety scope of this artificial cement marble surface layer material is (weight percent):

High-alumina cement 45-99.5%

Portland blast 0-16%

Quartz sand (powder) 0-45%

Pigment 0-10%

Alum 0-0.5%

The said components sum is 100%, and during stirring, water: the ratio of cement (high-alumina cement and Portland blast sum) is 0.3-0.6.

The preferential moiety scope of selecting is (weight percent):

High-alumina cement 50-65%

Portland blast 2-8%

Quartz sand (powder) 25-35%

Pigment 0-10%

Alum 0-0.05%

Above-mentioned component sum is 100%.

When mixing compound, the preferential water of selecting: cement (high-alumina cement and Portland blast sum) is 0.4-0.6.

The manufacture method of this artificial cement marble is the same with other manufacture method for artificial marble, and through operations such as molding, batching, moulding, the demoulding, maintenances, but manufacture method of the present invention has following feature:

1, molding: with the base plate of ganoid material as mould, in the time will manufacturing the artificial marble of surface band three-dimensional pattern, can manufacture on die bottom plate as having carved required decorative pattern, the frame of mould is manufactured with plastics such as calcium-plastic board bar; Or manufacture with metallic substance such as aluminum alloy bar or with the glass lath, be cemented on the die bottom plate with non-setting adhesive or adhesive tape.

2, batching: the preparation of surface layer slurry: ball milling is mixed, also carried out together to ratio in accordance with regulations with high-alumina cement, Portland blast, pigment; The fineness that makes compound is at 200-400 order (0.038-0.074mm), the quartz sand (powder) of adding regulation ratio and water cement ratio in accordance with regulations add water and stir the preparation of base layer compound: stir by ordinary mortar or concrete proportioning mixing and water adding according to desirable strength with ordinary Portland cement or high-alumina cement, fine aggregate such as sand, coarse aggregate such as cobble;

3, moulding: at first surface layer slurry is poured in the mould; Thickness is 0.2-2mm, floating with trowel, when needing upper layer to have different color decorative patterns simultaneously, can pour into a mould the slurry of one deck light color earlier, water one deck dark color again, starch into required decorative pattern shape with the trowel binder, also can piece together on mould with the marble fritter earlier and make various patterns, pour into surperficial layered material again, add after capstock is smooth one deck enzyme hinder  poh ǜ  poh ┖ take off that  ⑸ dust ɑ snail is negative is appointed by the uncommon ㄋ  chirp moon bright  father ⑸  of dust ┑ curtain ancient type of banner hoisted on a featherdecked mast play approve: 1), its thickness is 0-1.0mm, and the wetting base layer compound of spraying water is added on the dry ash layer, then the goods gang mould after the moulding is placed on to vibrate on the shaking table together to make goods closely knit smooth;

4, maintenance: the goods after the moulding are put into the thermostatic chamber of good leak tightness, and temperature is 20 ° ± 3 ℃, and temperature is 80-100%, and the time was about about 4 days;

5, special processing: the goods after thermostatic curing is good are put into alum solution and were soaked 0-24 hour, alum solution concentration is the 0.5%-8%(weight percent), the content of its surface layer alum of the goods after the processing is the 0-0.5%(weight percent), the length of soak time and the concentration of alum solution contain how much deciding of Portland blast amount by upper layer, content is low, then required time is long, the concentration height, and Portland blast content is high to a certain degree can not needing alum solution to handle;

6, natural curing: with the goods demoulding, at normal temperatures, water seasoning is to meeting service requirements.

In manufacturing processed, if in the upper layer prescription during no Portland blast, then goods must pass through the processing of alum solution.During molding, die bottom plate can adopt embossed glass.

This artificial cement marble low cost of manufacture, do not need sand milling, wax, polishing process, surface smoothness height, indeformable, frost mist free, not masked surface hardness height are suitable for doing building and ornament materials such as shingle nail, ground panel (brick), deck plate, desktop, top ceiling etc.

The present invention manufactures the embodiment of floor tile:

Be that the sheet glass of 5mm does die bottom plate, makes the length of side with plastics or aluminium alloy row culture mould side frame with ordinary plate glass such as thickness be 500 * 500mm mould; With Portland blast, high-alumina cement, orange pigment is by being the 200-400 order with the ball mill ball milling to granularity after 1: 9: 1 mixed, the quartz sand (powder) of raw material weight 20% above adding then, 40% the water that adds cement weight again is that water cement ratio is 0.4, stir, made the surface layer mortar, this mortar is poured in the mould, thickness is about 1mm, smooth good, form the upper layer of artificial marble, on upper layer, spread one deck by high-alumina cement and quartz sand (pressing the dry mash of preparation in 1: 1 approximately) thickness 0.5mm, the spray water wetting ordinary Portland cement mortar that will prepare separately again or concrete material (proportioning decides according to desirable strength by ordinary mortar or concrete), water on surperficial layered material, on shaking table, vibrate, make it closely knit smooth, the thickness of whole goods is 10-12mm, after the forming, goods are moved into controlled temperature is 80-100% 20 ± 3 ℃ of humidity in the thermostatic chamber, fixed temperature and humidity maintenance three days, remove frame then, it is the 4%(weight percent that goods are put into concentration) alum solution 24 hours, take out goods, take down die bottom plate, water seasoning is about seven days afterwards, so just made one bright in luster, bisque light such as minute surface energy have the excellent decoration effect as the floor tile that marble compares favourably, for being difficult for surface abrasion is bad in transportation, with self-adhesive paper seal surface, after installing, throw off gummed paper again.

The artificial cement marble case hardness made from the present invention＞45 barbey degrees, surface gloss＞92 degree can be up to 110 degree, rupture strength＞48kg/cm², it is indeformable to expose to the sun and rain, and not masked, the frost that do not whiten can satisfy the requirement on using fully, and color and the decorative pattern on surface can be allocated arbitrarily.
