Description
Technical field
The present invention relates to the production technical field of ceramic tile, relate in particular to a kind of preparation method of natural-like stone brick.
Background technology
The ceramic tile of natural-like stone, because its surface has the effect of lithotome, lower than lithotome price, change in pattern is more, natural-like stone brick is more welcomed by the people.At present, the molding device that prior art adopts and method are all cloth, compression moulding, whitewashing, dry and sintering.Powder pressing is whitewashed after becoming adobe, slurry sprays on adobe face according to design requirements, adobe after spray enters in dry cellar for storing things and is dried, can in spray process or course of conveying, mobility or the glutinous viscosity because of slurry self can there is micro-distortion in said process in the pattern texture just having sprayed in adobe, cause pattern texture meticulous not, true to nature, cannot well show the texture of magma flow in stone material.
Summary of the invention
The object of the invention is to propose a kind of preparation method who shows the natural-like stone brick of magma flow texture in stone material, lines is more fine and smooth clear.
For reaching this object, the present invention by the following technical solutions:
A preparation method for natural-like stone brick, comprises the following steps:
A, powder pressing is become to dry after adobe;
B, the mode of dried adobe level or inclination is transported to digital spray gun group below carries out slurry spray and adobe heating, adobe is sprayed according to the figure designing in advance by described digital spray gun group in the heating zone of 70 ℃-350 ℃, and the angle of adobe and digital spray gun group is less than 90 °;
C, adobe are transported to after having whitewashed in dry cellar for storing things, and the slurry of effects on surface is dried;
D, whitewashing is completed and dried adobe is reprocessed, final finished is natural-like stone brick.
Preferably, the water ratio of described slurry is 35%-50%.Water ratio has certain mobility at the slurry of 35%-50%, in the adobe of tilting, can occur to flow, flow effect changes with the size of water ratio, and water ratio is higher, and flow effect is more obvious, while spraying due to slurry, be provided with heating, Heating temperature is adjustable, although the water ratio of slurry is larger, the water ratio of adobe also can remain on below 2.5%, guarantee the intensity of adobe, be not easy to split brick.Water ratio, at 35%-50%, avoids water ratio too high, and the mobility of slurry is too high, and the magma flow effect of formation can be because of mobile being affected voluntarily of slurry, and mobility is too low, is unfavorable for the spray of spray gun, is also unfavorable for the control to spraying effect.
Preferably, the processing course of conveying of described adobe adopts Belt Conveying.
Preferably, the heating zone in described step b adopts sun lamp group type of heating, infrared heating groove mode or microwave heating groove mode to heat the adobe spraying.
Preferably, described slurry adds dispergator and defoamer in preparation, and described dispergator is one or more in tripoly phosphate sodium STPP, PC67 or water glass, and described defoamer is liquid detergent or SE57.
Preferably, after described step c has been dried, adopt one or more means in silk screen printing, roll printing or spray ink Printing to print.
Preferably, in described step b, adobe is transported to digital spray gun group below with inclination 0-15 °.
Preferably, the spray gauge control of described step b slurry is at 0.4-6mm.
Preferably, the heating zone in described step b adopts sun lamp group type of heating, infrared heating groove mode or microwave heating groove mode to heat the adobe spraying.Heating zone is arranged on the below of adobe, and sun lamp group is that sun lamp makes progress vertical irradiation in the back side of adobe, and heating efficiency is high, can auto-breaking during overheated or voltage instability, circuit is played to certain provide protection.In heating tank, use the back side to adobe of heat build-up lamp or heating resistor etc. to heat, also can use microwave or infrared heating, simple in structure, easy for installation, and use electric energy heating, to adobe, can play safe heating drying effect.
Preferably, fineness requirement 400 order-1000 mesh screen residues of described slurry are that the zero fineness requirement of slurry is tailed over now in 400 order-1000 is zero, are can by spray gun, to adobe, be sprayed smoothly in order to ensure slurry, avoid slurry to stop up in spray gun.
Preferably, after being dried in described step c, the water ratio of adobe is below 0.5%.Assurance adobe below 0.5%, makes adobe have enough intensity to carry out silk screen printing or roll printing at the water ratio that goes out to be dried cellar for storing things.
Preferably, the rework process of described steps d comprises glazing, and described glazing mode is that bell-jar drenches glaze.Steps d glazing can play a protective role; and can there is certain decoration function; as use transparent glazing; can increase the glossiness of brick face; decorative pattern under glaze can seem that stereoscopic sensation is more strongly full; improve the vision texture of lithotome magma flow, under unglazed and sub-light glaze, will make under glaze decorative pattern indistinct, better show the effect of lithotome fracture.Adopt bell-jar to drench glaze, pouring glaze effect is even, bubble pin hole is few.
Beneficial effect of the present invention: 1, spray and heating are carried out simultaneously, make adobe can retain preferably magma flow texture in stone material; 2, lines is more fine and smooth clear; 3, stereoscopic sensation is more strongly full, improves the vision texture of lithotome magma flow.
