Abstract
A kind of artificial marble and method for making thereof are that the substrate concrete made with high-alumina cement, flyash, sand, stone, SM, water (adding blast furnace water quenching copper ashes or blast-furnace slag, water-proofing powder in case of necessity) and the band color of being made by high-alumina cement, SM, pigment, water (adding sand or glass powder, silica flour, water-proofing powder, silicon sol, tetraethyl silicate in case of necessity) or the capstock of decorative pattern are formed.Its method for making is that capstock and substrate concrete are put into die for molding in proper order, through quietly stop, water is supported, the demoulding, water is supported, emptyly supported again, waxing forms, product performance are superior.The present invention fully utilizes industrial waste in a large number, thereby makes with low cost.
Description
The present invention relates to material of construction and production method, particularly make building and ornament materials and technology thereof about comprehensive utilization industrial waste-flyash.
Along with the raising of production development and living standards of the people, kind and consumption that the finishing material of buildings needs are on the increase, and natural marble and sintering facing plate are both artistic and practical, use but cost an arm and a leg to be difficult to popularize, and particularly the sintering rule consumes a large amount of energy.At present artificial marble all uses all kinds cement, adds some properties-correcting agent (as synthetic resins), and mineral filler and pigment and make.Yet the common shortcomings such as later strength is poor, the accumulation of salt in the surface soil that exist.The artificial marble made from alum scholar cement, silica sand, titanium dioxide, pigment that the open 53-50225 of Japan special permission introduces has corrosion-resistant preferably, weathering resistance and surface smoothness height, but later strength decline.CN86102478A is described to be based on aluminate shrinkage-compensating cement, sulplo-aluminate short-term strength cement, sulplo-aluminate microdilatancy and worker's type low alkalinity cement, add stopping composition, pigment and water, divide the maintenance of three layers of (flower-pattern layer, middle layer, bottom) once shaped room temperature, demoulding to form.Three days intensity of finished product is: anti-folding＞4.4MPa; Resistance to compression＞44.1, glossiness＞80.
The present invention notices that China is that the annual flyash of discharging of thermal power generation industry of fuel reaches 7,000 ten thousand tons approximately with the coal dust, utilize at present and make aerating concrete, wall body brick, floor tile etc., its utilization ratio only has about 27%, and most of or occupation of land is stacked, or enter rivers,lakes and seas, cause environmental pollution.The objective of the invention is to utilize this industrial waste, add exciting agent, chemical assistant, filler and pigment, make the inorganic artificial marble of excellent performance with distinctive processing method.
Manufacturing process of the present invention as shown in drawings.The surface of beautiful decorative pattern has suitable intensity and weather resistance again in order to make the existing light of artificial marble, becomes substrate concrete and capstock with different preparation of raw material, carries out steps such as stone moulding, water is foster, sky is supported and forms.In basic unit's agglutinate, use high-alumina cement and flyash to be main raw material, show that after deliberation calcium aluminate in the high-alumina cement is as the activator of flyash, impel flyash generation pozzolanic reaction and make this concrete have early strength considerably, and make its later strength continue development in the long duration.Employed flyash can be fine, also can use poor quality (levigate water demand ratio＞105%) product.Add water reducer SM(terpolycyantoamino-formaldehyde resin) can improve concrete workability and improve intensity.Add water-proofing powder, blast-furnace slag, blast furnace water quenching copper ashes etc. in case of necessity.The raw material ratio of basic unit's bonded concrete (weight) is:
High-alumina cement #525 1
Flyash 1.70～3.00

Blast furnace water quenching copper ashes or blast-furnace slag (fineness 0.08 square hole sieve, tailing over is 7～8%) 1.10～1.20
Water-proofing powder 0.002～0.003
To become substrate concrete behind its mixing.
Capstock is that proportioning (weight) is with high-alumina cement, SM, pigment and water main raw material:
High-alumina cement #525 1
SM 0.010～0.013
Pigment 0.029～0.060
Water 0.032～0.035
Add in case of necessity:
Sand (modulus 1.118～1.437, particle diameter 0.074＜d＜0.6)
1.00～1.10
Glass powder (granularity: the 0.08mm square hole, tailing over is 0.6～0.8%)
0.15～0.30
Silica flour 0.20～0.25
Water-proofing powder 0.002～0.003
Silicon sol 0.010～0.013
Tetraethyl silicate 0.006～0.008
Glass powder, silica flour and water-proofing powder are the surface layer active filler, can singly use, and also can mix use, and its total amount is 1.00～1.64.
Concrete method for making is:
(1) substrate concrete material:
(1) with high-alumina cement, flyash, add blast furnace water quenching copper ashes or blast-furnace slag, water-proofing powder in case of necessity and add grinding in ball grinder in proportion, its fineness is the 0.08mm square hole sieve, and tailing over is 5～8%, and this is basic unit's agglutinate.
(2) solution that is made into of basic unit's agglutinate and sand, stone, water, SM is in forced mixer, and it is standby to stir into the substrate concrete material.
(2) capstock
(1) high-alumina cement, sand (or segment glass powder) being added in case of necessity silica flour, water-proofing powder etc. inserts grinding in ball grinder evenly to become the surface layer agglutinate standby.
(2) part surface layer agglutinate and background color pigment are added the SM emulsion and stir well, this is a foundation.
(3) a small amount of surface layer agglutinate is done inhomogeneous the mixing with decorative pattern pigment, pour in the mould, shakeout through vibration and add foundation again after being paved with, still be paved with the back and add substrate concrete, vibration 3～5min, surface layer is 1～1.5mm, plate thickness is about 20mm.Mould inserted together with reason slabstone humidity is 90%, temperature is 15～20 ℃ of quiet 6h of stopping, then to Mo Neijia water 10～15mm, carry out the 24h maintenance, the demoulding then, with the light water curing 3 days of in the water curing groove, showing up that faces up, be 10～15 ℃ in temperature again, relative humidity is the room air health 10 days more than 60%, and then resonable slabstone light face is with cloth wheel waxing polishing.Certainly also pigment directly can be added and stir evenly in the surface layer agglutinate or irregular back injection molding is made the marble slab of solid color or irregular look.The marmorean performance index made from the present invention are:
