Abstract

The present invention relates to the production method of the artificial marble of the concrete decorative effect of a kind of inorganic raw material production, belong to building material field.The present invention adds sodium silicate water glass, cement accelerator Sodium hexametaphosphate 99 and cement again and early executes agent trolamine composition lining in traditional inorganic artificial marble raw material, after adding the bed material back-up coat, through artificial control maintaining process, thereby obtain intensity height, good brightness, the not yielding and technology marble that fades.

Description

Process for producing artistic inorganic marble

The present invention relates to a kind ofly have the production method of the artificial marble of decorative effect, belong to building material field with inorganic raw material production.

In recent years, various organic and inorganic artificial marbles have appearred on the market, and immediate with the present invention be CN88104022, the described artificial marble of 3 applications for a patent for invention disclosed " a kind of production technology of inorganic marble ", it is with high alumina stone mud, quartz sand, the pigment powder, inorganic substance such as water and water glass are as main surface material, use high-alumina cement, river sand, water is put into glass template natural curing moulding as back-up coat, the marble of this explained hereafter, raw material sources are abundant, price is low, but its long-time back variable color easily, bulk marble slab easy deformation used.The luminance brightness on intensity and surface awaits to improve.

The present invention adjusts lining and back-up coat composition according to the weak point of foregoing invention, and carries out strictness control on maintaining process, and every physical index of product is further enhanced.

The present invention adopts high-alumina cement, dioxide-containing silica 99, quartz sand more than 8%, inorganic pigment powder with acid-proof alkaline, add sodium silicate water glass through the science preparation, cement accelerator Sodium hexametaphosphate 99 and cement are early executed agent trolamine composition lining (wet look) and are deployed into the thin pulp shape, pour in glass (5mm the is thick) template that cleans up, housing adopts plastic strip, through spontaneous curing in 1～2 hour, wait to become semicure shape (when being anhydrous) and add bed material again, raw material adopts same high-alumina cement and the selected river sand that cleans up, the clear water that adds an amount of ratio is mixed even post-reinforcing in model, carry out wet curing (watering clear water once) in 36 to 60 hours through adding a cover 2～3 centimeters thick wet foams after 2～3 hours every 3～5 hours, remove foam then and carry out natural dry curing in 24～48 hours, withdraw from the glass template at last, the mould bar promptly becomes high strength, as bright as a sixpence high quality artificial marble.

Artificial marble production process of the present invention requires height, for reaching the natural vein effect and producing marble wall picture and furniture panel attractive in appearance, promptly adopt not homochromy pigment ratio sand, grey slurry, when being deployed into decorative pattern through checking colors, pour in the template with special cast instrument (as dustpan) is artificial with controlling, produce decorative patterns such as natural wood veins, marble striped, takes landscape.Pigment can adopt: 1, titanium dioxide; 2, red iron oxide; 3, Manganse Dioxide; 4, chromoxide green; 5, iron oxide yellow.

The various raw material deal of lining ratio:

1, high-alumina cement 1(625-725 number);

2, quartz sand 1,2(40-70 order, silicon content 99,8%)

3, inorganic pigment powder 0,3-0,5(220-320 order, acid-fast alkali-proof)

4, chemical water 0,6-0,7

The chemistry water be add 3 in 100 ml waters, 3-3,5 milliliters of sodium silicate water glass, add 2,5-3 milliliter Sodium hexametaphosphate 99, add 0,05 milliliter of trolamine.

The various material mixture ratios of bed material back-up coat:

1, high-alumina cement 1 (625-725 number)

2, river sand 2 (20-40 order)

3, tap water 0,5-0,6 (pH value 7-8)

The objective of the invention is to improve the intensity and the surface brightness of existing inorganic artificial marble, and solve the distortion and the problem of fading of product.

Below for an embodiment:

1, the black decorative pattern of white background is drawn at first lining proportioning: high-alumina cement (No. 725) 1; Quartz sand (60 order) 1,2; Pigment (250 order) 0,2; Chemistry water 0,6.Pigment is that 80% white pigment is mixed titanium dioxide 20%, chemical water be add 3 in 100 ml waters, 3-3,5 milliliters of sodium silicate water glass, add 2,5-3 milliliter Sodium hexametaphosphate 99, add 0,05 milliliter of trolamine.Bed material back-up coat proportioning: high-alumina cement (No. 725) 1; River sand (40 order) 2; Tap water 0,6.When lining, bed material were all poured in the template after 3 hours, soak in the tap water with 3 centimeters thick plastic foams, topped then in the marble bottom, watered once every 4 hours, through wet curing in 48 hours, remove wet foam, after natural dry curing in 48 hours, form product again.

Claims

1, a kind of process for producing artistic inorganic marble, it adopts high-alumina cement, the quartz sand that cleanup acid treatment is crossed, inorganic pigment powder, water and water glass constitute lining and are deployed into the thin pulp shape, be cast in the glass sheet frame of pickling, natural curing becomes the semicure shape, then with high-alumina cement, the river silt poach washed as back-up coat, maintenance moulding then, the present invention is characterised in that:

(1) the various raw material deal of lining ratio:
