C) prepared by underlying material
First by ore in sand form, building stones and cement using mass ratio as (0.5~1.2)：(0.8~1.5)：(0.4~1.1) the 3rd is added
It is mixed evenly in vertical mixer, cement additive is then added into the 3rd vertical mixer is stirred, wherein
The weight of cement additive is accounted under the 1.2~2.5% of gross weight, normal temperature condition and stirred within 10~15min, then by artificial
Load in above-mentioned mould, thickness is 60~80mm, 3~7d of natural curing；
D) it is stripped
After steel gray layer, surface layer and bottom in mould reach setting intensity, demoulding processing is carried out；
E) polish
Stone material after the demoulding is lain in a horizontal plane in machine table, is roughly ground with stainless-steel grinding brush, grinder is controlled during grinding
Rotating speed be 140~180r/min, laterally vertical each grinding 2~3 times, steady mobile grinder during grinding, and control abrasive brush
The translational speed of horizontal direction is 2~3min/m, untill stone surface is smooth；
F) grind
After corase grind, abrasive brush is changed, in progress, fine lapping is processed, and is 200~300r/min by the adjustment of rotational speed of grinder, horizontal
To vertical respectively grinding 3~5 times, the horizontal movement velocity that abrasive brush is controlled during grinding is 4~6min/m, is added in process of lapping
Water, and sparge pipe is placed in the both sides of abrasive brush moving direction, grinding is rinsed well after terminating with clear water；
G) Anti-seeping technology
After end to be ground, stone material is dried with drying baker, spary anti-fouling agent, the first upper and lower surface in stone material after drying
Brushed, brushed back and forth along same direction 2~3 times, until the upper and lower surface of anti-fouling agent and stone material is completely attached to, Ran Hou
The left and right side of stone material is sprayed, and it is 1~3min/m to control speed of the shower nozzle in moving process, is come along the side of stone material
S-shaped spraying is returned, is sprayed 2~3 times, spary is protected after finishing；
H) crystallization treatment
After stone material Anti-seeping technology maintenance 24h, crystal face cure process is carried out to stone surface with crystal hardening accelerator, it is clear to stone surface
After reason is clean, crystal hardening accelerator is sprayed on stone surface, with steel wool uniformly around on abrasive disk, with crystal face processor by first
Order is ground back and forth in stone surface from top to bottom backward from left afterwards, and the rotating speed for controlling crystal face processor is 140~180r/
Min, is handled 2~3 times back and forth, finally carries out encapsulation process to stone material with stone material sealant, is rinsed and is carried out after drying with wax-polishing machine
Waxing polishing.
8. a kind of preparation technology of rectangular slab of stone formula modelled after an antique according to claim 7, it is characterised in that：Step b) capstock systems
The mass ratio (1.2~1.8) of the pigment, the cement and the ore in sand form in standby：(95~110)：(130~155).
9. a kind of preparation technology of rectangular slab of stone modelled after an antique according to claim 7, it is characterised in that：In prepared by step c) underlying materials
The ore in sand form, the mass ratio of the building stones and the cement be (0.8~1.1)：(1.0~1.4)：(0.5~1.0).
