Embodiment
Further illustrate technical scheme of the present invention below by embodiment.
Embodiment 1
As shown in Figure 1, it from bottom to top comprises that end base layer 1, printed layer 2, glass coating 4, glass coating surface arrangement have pit 31, have layer of metal gloss layer 5 in described pit surface to the brilliant brick of a kind of throwing successively.
Referring to the appended flow process signal of Fig. 1; Select the ceramic tile that preparation specification is 1000 × 1000mm, its blank raw material is for known taking feldspar, clay, sand etc. as main raw material in the industry, be aided with again other auxiliary materials such as talcum, certainly, can also add according to actual needs a zirconium silicate brightening or coloured ceramic body stain.
Particularly, with reference to Fig. 1, its manufacture method comprises the steps:
A, feed proportioning ball milling is carried out to compacting after mist projection granulating form adobe the dry end base layer 1 that forms;
B, first form frit layer 3 by forming the rear cloth frit of printed layer 2 by spray ink Printing stamp again after screen printing; Here the frit that used is preferably transparent or semitransparent frit, and what select in the present embodiment is clear frit;
The PVA solution fixing agent of C, spray content 0.01% is fixed, and extrudes lines at the mould of the not dry front burr with moulding of fixing agent, makes clear frit layer occur the deep mixed of degree of depth 1-4mm, pit 31 not of uniform size;
D, burn till; Under oxidizing atmosphere, in roller kiln, burn till with 1100~1250 DEG C, firing period is 90-120 minute;
E, in the work in-process pit baking, spray one deck fineness 300 mesh screen residues 0, viscosity is 500cps, spraying fraction of coverage 9m
2the metallized coating of/kg is dried polishing after 10 minutes at 280 DEG C, packaging warehouse-in.
Certainly, also can be on whole brick face metallize gloss paint, by top layer jettisoning, only retain part in pit by polishing.Just can waste like this metallized coating.
Metallized coating described here refers to by fluoro-resin, high-quality color stuffing, auxiliary agent, solidifying agent etc. and forms; Wherein contain lemel, therefore have metalluster, different metal group branches present different colours, and for example aluminium or silver can present silver color or silver gray, and gold can present golden yellow.
By regulating known parameter (base substrate cloth amount, stamp is the consumption of stamp-pad ink used and ink, the consumption of frit charity etc., these parameters are that those skilled in the art can carry out suitably adjusting as required), at the bottom of the brilliant brick of throwing of the present embodiment after firing, base layer 1 thickness is 8mm, printed layer 2 thickness are 0.3mm, and glass coating 4 thickness are 0.5mm.
The present embodiment precompressed before firing forms pit, and metallized coating is sprayed in pit, matt after having avoided the metal glaze that brings firing front upper metal glaze in prior art to disperse to fire, the problem bad with frit adaptability, resultant metal texture is strong, and glossiness is high, and metal can be mutually compound with crystallite texture, the harmony of brick face, expressive force is strong.
Produce the brilliant brick of throwing with metalluster effect by this method, excellence rate is more than 85%; And adopt traditional method of executing metal-lustrous glaze, and because the dissemination of frit in the time of melting obtains product effect and cannot reach expection, excellence rate is only 40% left and right, and waste is serious, and production cost is high.
In addition, select to adopt the product that obtains layer of metal gloss coating on surface spraying metallized coating or the brilliant brick product of the throwing after burning by enamel firing process, the product of preparing with the present embodiment together carries out the test of hairbrush brushing, obtain the product brushing 30 times of layer of metal gloss coating by enamel firing process on the brilliant brick product of surface spraying metallized coating or the throwing after burning time, metalluster coating starts to come off, 50 times time, substantially come off completely, and the product that the present embodiment provides, in the time of 50 times, still keep good metal lustre decorative effect, after 150 brushings, just start to come off.
Embodiment 2
With reference to accompanying drawing 1, in this enforcement, manufacturing specification is the brilliant brick of throwing of 1000 × 1000mm, and its manufacturing process in turn includes the following steps:
A, feed proportioning ball milling is carried out to compacting after mist projection granulating form adobe the dry end base layer 1 that forms; Then spray water brick face is wetting, charity one deck protection glaze;
B, form the rear cloth clear frit of printed layer 2 by roller printing and form clear frit layer 3;
The PVA solution fixing agent of C, spray content 0.1% is fixed, and extrudes lines at the mould of the not dry front burr with moulding of fixing agent, makes frit layer occur the deep mixed of degree of depth 1-3mm, pit 31 not of uniform size;
D, burn till; Under oxidizing atmosphere, in roller kiln, burn till with 1100~1250 DEG C, firing period is 90-120 minute;
E, in the work in-process pit baking, spray one deck fineness 300 mesh screen residues 0, viscosity is 200cps, spraying fraction of coverage 7.5m
2the metallized coating of/kg is dried polishing after 20 minutes at 200 DEG C, packaging warehouse-in.
The metallized coating of selecting in this enforcement is golden metallic luster coating.Certainly,, in application, in order to obtain the more effect of horn of plenty, the metallized coating collocation of multiple color can be used.
The present embodiment was executed one deck protection glaze before executing frit; and execute protection glaze before trickle; pin-holing glaze bubble while having avoided drenching protection glaze; simultaneously; because protect glaze beginning fusing point lower than frit after adding one deck protection glaze, suppress gas that in adobe sintering process, decompositions produces and reduce gas and enter the defects such as frit layer formation pin hole and small bubbles thereby first produce glassy phase in sintering procedure.
By regulating known parameter, brilliant its end base layer 1 thickness of brick of the throwing of the present embodiment is 10mm; Printed layer 2 thickness 0.1mm; Glass coating 4 thickness are 3mm.
It is 87% that the metalluster that after burning prepared by statistics this method is thrown brilliant brick excellence rate.
