Abstract
The present invention relates to upper granite material coloring liquid and a coloring method. The coloring liquid is composed of ferric nitrate, sodium ethylhexyl sulfate, 3.6-nekal and mineral acid, wherein the ferric nitrate is used as a coloring agent; the sodium ethylhexyl sulfate is used as a wetting agent; the 3.6-nekal is used as a penetrating agent. The coloring method comprises: air in granite gaps is firstly removed by vacuum air extraction; then, pressurizing, impregnating and coloring are implemented. The obtained granite has brilliant colors, and the pattern of the granite is very similar to that of natural colorful granite. Thus, the obtained granite can not be distinguished. The present invention is the up-to-date coloring liquid and the coloring method.
Description
The present invention relates to granite material coloring liquid and staining method, particularly granite material coloring liquid and pressurization staining method.
As everyone knows, granite essential mineral composition is quartz, feldspar, hornblende, pyroxene, peridotites and biotite.If contain different feldspars or heavy metal oxide then presents distinct colors, as contain potash feldspar or the oxidation iron rule shows red in the granite, manganese oxide then is black or the like.Though natural granite has part to present even chromatic colour, ratio is very little, and most granite is that color is all even inadequately not bright-coloured, and linen granite is in the majority.In order to satisfy the need of the flawless finish granite in slab that grows with each passing day, often adopt the artificially coloring method that natural granite is carried out deep processing.
At present, the granitic colorize method that adopts can be divided into two big classes both at home and abroad, one class is the hyperchromic method of high temperature that mineral dye is smeared or flooded, be about to mineral dye and spread upon plate surface or sheet material is immersed in after infiltration in 1-2 days of pigment liquid back warp and the reaction again through pyroprocessing, smear the dipping pyroprocess of pyroprocess and Chinese patent 94113040 as Chinese patent 92106377 and Japanese Patent JP61291476.Its shortcoming be the cycle consuming time long, energy consumption is high, coloring effect is not as good as people's will; Another kind of is organic dye coated method, the weather-proof and poor water resistance of the coating of this method, and fade easily.The content that is disclosed as English Patent BR8501553.
The object of the present invention is to provide a kind of perviousness strong, the granite decorative board coloring liquid of firm coloration and pressurization staining method.The painted time of this method is short, and general needed 8 hours just can finish painted operation.
Embodiment of the present invention are as follows:
One. the every premium on currency of coloring liquid proportioning contains the gram number
Tinting material: the iron nitrate that contains 9 crystal water: 1000 grams are to 1450 grams
Wetting agent: 40%2-ethylhexyl sodium sulfate: 2.5 grams are to 10 grams
Permeate agent: 3, the 6-sodium dibutyl naphthalene sulfonate: 2 grams are to 8 grams
Mineral acid: be 68% nitric acid: 50 grams are to 100 grams
Two. colorize method:
(1) granite slab being placed general impregnating autoclave, is 7.3 * 10 in vacuum tightness
-3-2.3 * 10
-3MPa.
(2) in jar, suck coloring liquid.Be forced into 0.8-1.6MPa then, constant voltage 1 hour fully immerses in the hole and slit of granite in slab coloring liquid.
(3) granite in slab is taken out in release, and constant temperature made iodonium salt be decomposed into red ferric oxide in 2 hours under 180-250 ℃ of temperature.
(4) (2) (3) operation three times repeatedly.Polish according to a conventional method then, operation such as waterproof, weathering resistance coatings.Certainly, tinting material of the present invention is selected with the painted purpose of difference, as wants red coloration, just selects trivalent iron salt for use, then selects manganous nitrate for use as black, as green, then selects cupric nitrate or the like for use.Though the used tinting material of these tinting materials and prior art is the same, adds wetting agent and permeate agent in the present invention, be that prior art institute is different or unexistent.
The effect of wetting agent is the interfacial tension that reduces colourant solution, helps in the wetting hole of going in the granite of colourant solution.
The effect of permeate agent is to promote the coloring liquid porous to go into the hole in the granite and the ability of slit, and is attached in the granite firmly.
The effect of mineral acid is to prevent iron salt hydrolysis, guarantees the stability of colourant solution.
In method, the present invention adopts and earlier use vacuum suction, so that evict gas and the moisture content that is adsorbed in the granite slit from and help the effect of tinting material infiltration and firm attachment, as for the pressurization when flooding, quicken the infiltration of tinting material beyond doubt, this also is one of feature of the present invention.
Following preference is described in detail the present invention, but does not mean that limitation of the scope of the invention:
Example 1: with 1200 millimeters * 600 millimeters * 20 millimeters granite in slab, cleaning is dried, and places an airtight general impregnating autoclave, is evacuated to 3.3 * 10
-3MPa, constant voltage 1 hour sucks the coloring liquid in advance prepared then to soaking till full this granite totally 200 liters in jar, the every premium on currency of this coloring liquid contains iron nitrate 1100 grams, 40%2-ethylhexyl sodium sulfate 5 grams, 3,6-sodium dibutyl naphthalene sulfonate 5 grams, 68% nitric acid, 75 grams.In jar, be forced into 1.0MPa, after the constant voltage 1 hour, sheet material is taken out in release then, move in the baking oven, be warming up to 200 ± 10 ℃, constant temperature 2 hours, the cooling back is taken out sheet material and is got pale brown red sheet material, polish, polish, be coated with waterproof, weather-resistant coating later on according to a conventional method, dry naturally, get promptly that decorative pattern is clear, the lines flow smoothly, exactly like the granite of natural colour.
Example 2: except that changing every premium on currency into, each component in the tinting material contains iron nitrate 1300 grams, 40%2-ethylhexyl sodium sulfate 7 grams, and 3,6-sodium dibutyl naphthalene sulfonate 7 grams, 68% nitric acid, 85 grams and vacuum tightness are 6.3 * 10
-3MPa is pressurised into 1.4MPa, and heating is outside 230 ± 10 ℃, and all the other conditions are identical with example 1, and it is mashed also to make color class, brightly painted granite.
Advantage of the present invention is as follows:
1. painted Veneer granite slab material is bright-colored, and clean mark is colour-fast, with natural coloured Granite is very compeled true.
2. the coloring liquid raw material is easy to get, and preparation is simple, and permeability is strong, the fastness height.
3. colorize method is reliable, and is effective.
