Abstract

The granite plate coloring processes include coloring liquid compounding, plate degassing, coloring and color fixing. The key points are the material of coloring liquid containing ferric chloride 10-40% and aluminium powder 2.5-5%, the coloring while heating at 70-100 deg.C for 0.5-1 hr, the color fixing adding potassium permanganate and at 150-300 deg.C for 2-3 hr, and the final grinding treatment.

Description

Red-cooouring technology of light-colour granite plate

The invention belongs to the granite coloring technique scope, relate to the granitic a kind of red colored technology of light color.

Light color granite is a kind of low-grade granite, in order to improve the decorative effect of this low-grade granite in slab, in the prior art, application number provides a kind of coloring process of natural granite dalle for 93112628.2 patent application, it is the sheet material of intended for dyeing to be inserted to add heat soaking in the inorganic dye liquor painted, take out cleaning-drying again, insert fixation in the fixation liquid.This coloring process, though can realize granitic painted,, because this method is to belong to a kind of physical method basically, the poor permeability of dyestuff, multiple in surface colour, and color fastness is low, fugitive color, use value is little.Application number provides another granite coloring technique for 94113040.1 patent application, it is earlier granite in slab to be outgased, place again that to add the coloring liquid of water or organic solvent preparation with divalent iron salt, trivalent iron salt, aluminium salt, surfactant painted, be heated to the 300-400C fixation treatment after taking out cleaning-drying, use the Treating Cuttings with Paraffin Wax surface at last, though this method can be to realize the painted of granite in slab preferably, but, this method one is that the coloring liquid iron salt concentration is low, be again painted at normal temperatures, painted speed is slow, and is of light color, weak effect; The 2nd, lack oxygen supply in the fixation operation, the oxygen deficiency, the coloring liquid chemical reaction is insufficient, and color is difficult to reach the complete stability state, and color effect is poor, and color fastness is also lower.And have pernicious gas and emit, cause air pollution; The 3rd, because colouring agent adopts the high-melting-point divalent iron salt, color fixing temperature is up to 300-400C, is again directly the granite tabula rasa to be carried out paintedly, and sheet material light face can crack, and influences board quality; The 4th, coloring liquid directly adds the preparation of aluminium salt, the coloring liquid pH value is not adjusted, and the acidity height, corrosivity is big, equally also can influence the quality of sheet material.

It is simple that task of the present invention provides the colouring agent batching, cost is low, do not influence the granite in slab quality, there is no the red-cooouring technology of light-colour granite plate that pernicious gas pollutes, painted color fastness height, the high-grade red granite sheet material of good decorating effect, thus overcome the above-mentioned drawback of existing in prior technology.

Task of the present invention is improved on the basis of existing technology and is realized, it comprises preparation, the sheet material degassing, the painted and fixation operation of coloring liquid, and its main points are:

1, the coloring liquid raw material is ferric trichloride, aluminium powder and bleeding agent, is solvent with water, and concentration is ferric trichloride 10-40%, aluminium powder 2.5-5%;

2, to the temper tiniting of granite hair plates material, color temperature 70-100C, time 0.5-1 hour, treat to carry out again after the fixation polishing polishing of hair plates material;

3, in the fixation hothouse, add an amount of potassium permanganate during fixation, play oxygen supply and absorption chlorine, simultaneously, the granite in slab of putting into after painted heats up, to 150-300C, keep 2-3 hour fixation, said fixation also can divide low temperature and two temperature-time sections of high temperature to carry out.

The technology of the present invention coloring liquid batching is simple, and cost is low, and process route is feasible, and coloring effect is good, colour stable, and the granite quality is unaffected, and no pernicious gas pollutes, the high-grade red granite sheet material of pigmentable good decorating effect.

Embodiment 1: ferric trichloride 740 grams, dissolve with 1000 gram 65C warm water, add aluminium powder 50 gram successively, polyoxyethylene ether 20 grams are mixed into coloring liquid, 20 10 2CM put into hothouse with the canescence granite slab, the baking degassing in 1 hour substantially under 150 degree temperature, take out in the coloring liquid that drops into above-mentioned preparation in the back, under the 70-100C temperature painted 40 minutes, take out and dry in the air 30 minutes substantially; Put into 4 gram potassium permanganate in hothouse, put into above-mentioned painted granite hair plates simultaneously, heat temperature raising kept 3 hours substantially to cardinal principle 250C, slowly was chilled to normal temperature, took out the polishing polishing.Granite in slab through above PROCESS FOR TREATMENT is " Chinese red ", " Indian red " model color, cross section solid colour.

Embodiment 2: ferric trichloride 450 grams, and aluminium powder 30 grams, painted to C level Suya Pink, temperature 70-100 degree, 30 minutes time, fixation is divided two stages, the phase I, temperature 150C, 1 hour time, second stage, temperature 300C, 1 hour time, other are with embodiment 1.Through this PROCESS FOR TREATMENT, former C level Suya Pink sheet material color burn, beautiful in colour like A level Suya Pink, the cross section solid colour.

Embodiment 3: ferric trichloride 200 grams, and aluminium salt 20 grams, painted to the canescence granite in slab, color temperature 70-100 degree, 1 hour time, fixation phase I, temperature 200 degree, 1 hour time, second stage, temperature 250 degree, 1.5 hours time, other are with embodiment 1.Through this PROCESS FOR TREATMENT, the sheet material color is light red, near B level Suya Pink color, cross section solid colour.

Claims

1, a kind of red-cooouring technology of light-colour granite plate, comprise coloring liquid preparation, the degassing, painted and fixation operation, it is characterized in that the coloring liquid batching is ferric trichloride, aluminium powder and bleeding agent, with water is solvent, concentration is ferric trichloride 10-40%, and aluminium powder 2.5-5% is to the temper tiniting of granite hair plates, color temperature 70-100C, time 0.5-1 hour; Add an amount of potassium permanganate at the fixation hothouse during fixation, put into simultaneously through painted granite slab, heat temperature raising keeps 2-3 hour fixation substantially to 150-300C, slowly cools to normal temperature, takes out the polishing polishing again.

2, technology according to claim 1 is characterized in that said fixation is divided into low temperature and two temperature-time sections of high temperature.
