Abstract
Two-valence iron salt, three-valence iron salt, aluminium salt, surfactant and solvent are compounded into the granite coloring liquid. Degasified granite is first soaked in the said liquid, then withdrawn, dried, heated up to 300-400 deg.C, cooled to room temp. and finally treated with paraffin wax. The said process can color both the greyish white or the light-coloured granite into red, brown, yellow, brownish red or yellowish brown granite.
Description
The present invention is a kind of granite coloring technique, be with granite after physico-chemical process is handled, make granite into different color, with stone material as architectural decoration.The present invention provides a kind of granite painted new technology for building materials industry.
At present traditional granite coloring technique normally with inorganic or organic dye with physical method as modes such as soaking, smear, make staining fluid enter stone material and painted, this class methods poor permeability, dye layer is shallow, even rest on stone surface, thereby weathering resistance is poor, fugitive color.
Existing granite coloring technique mainly contains following several:
Prior art I: the high cobalt acid of nitrous sodium-amaranth method (is seen " chemical staining of natural ornamental stone ", Shandong Building Material College's journal, 1988.3, P86), after the HF vapour cure, place the high cobalt acid of nitrous sodium soup to dye granite building material, spill cover plate material surface with amaranth liquid at last, potassium felspar sand is dyed yellow as a result, and the Dou feldspar is by purple.The shortcoming of this method is: 1. HF is colourless toxic gas, operational difficulty in the processing, security is little, human body had certain toxicity, 2. granite is the complex construction of being made up of multiple composition (mainly being quartz, feldspar, mica etc.), and its profile and characteristic are extremely inconsistent, and this method is only dyed yellow, purple with wherein partly forming, can cause dyeing uneven, difficult quality guarantee.
Prior art II: granite is after the degassing is handled, immerse in the metal chloride solutions, taking-up is heated to 250 ℃, be cooled to room temperature,, get red granite with in the soda-lime solution and surface, its coloring liquid prescription is that metal chlorides such as Fe, Al, Cr (are seen " Coloring of Granite Stone Materials ", JP62,252,384).The granite color that this method obtains is single, only is red.
Prior art III: granite immerses in the salts solution of metal and strong acid reaction generation after the degassing is handled, and takes out and is heated to 250-300 ℃, is cooled to room temperature, uses the silicone oil treat surface at last.The ferric salt solution that generates with iron and strong acid reaction in this method to the dull coloring of the painted processing of stone material, only be red, and the coloring liquid quality is wayward.(seeing " Process for Coloring Granite ", US4,695,487).
Task of the present invention is in order to overcome the weak point in the prior art, utilize a large amount of existence of occurring in nature and cheap canescence and light granite, adopted coloring liquid unlike the prior art, obtained multicolour, competent high-quality granite attractive in appearance with new coloring process technology.
Distinguishing feature of the present invention is:
(1), good weatherability, have good weathering resistance (fast light, heat-resisting, water-fast) with the painted granite of this law, prolonged nondiscoloration, fade.
(2), the coloring liquid characteristics: the coloring liquid prescription is to be coloring material with divalent iron salt, trivalent iron salt, aluminium salt, and based on divalent iron salt, is equipped with an amount of permeate agent, the coloring liquid perviousness strong (with prior art II, III relatively).
(3), uniform coloring, color is attractive in appearance, adopts with a kind of coloring liquid, only changes the content and the process control condition of its main component, just can obtain different tones such as redness, brown, yellow, maroon, tawny, and uniform coloring.
(4), process characteristic: stone material immerses coloring liquid of the present invention after the degassing is handled, take out the post-heating temperature and be 300-400 ℃, handles stone surface (different with prior art II, III) with paraffin wax at last.
(5), security is good, the coloring liquid non-corrosiveness, the entire treatment process does not have influence to human body.
Granite coloring technique of the present invention does not see that domestic and foreign literature has identical report at present.
Granite coloring technique of the present invention mainly comprises coloring liquid and coloring process.
1, coloring liquid:
Prescription: be coloring material 1. with divalent iron salt, trivalent iron salt and aluminium salt, and based on divalent iron salt.Divalent iron salt can be Iron nitrate, ferrous sulfate, ferrous ammonium sulphate, iron protochloride etc.; Trivalent iron salt can be iron nitrate, iron(ic) chloride etc.; Aluminium salt can be aluminum nitrate, aluminum chloride etc.
2. solvent: water or organic solvent, organic solvent is advisable with alcohols.
3. tensio-active agent: can be ionic or nonionic surface active agent, fluorine surfactant, polymeric surface active agent etc. be advisable with alkylbenzene sulfonate, polyoxyethylated alkyl alcohol.
Ferrous content is advisable in 0.5-6.5% scope in the coloring liquid, and ferric content is advisable in 0.01-0.20% scope.
The preparation: with divalent iron salt, trivalent iron salt, aluminium salt is water-soluble or organic solvent in, other adds an amount of tensio-active agent, constitutes the strong granite coloring liquid of perviousness thus.
2, coloring process:
Granite building material is packed into after the degassing is handled in the encloses container, in container, inject above-mentioned coloring liquid.Taking-up stone material washing drying, again stone material is heated to 300-400 ℃, constant temperature 1-3 hours naturally cools to room temperature, handles stone surface with paraffin wax at last and promptly gets goods.Can change factor such as ferrous iron and ferric content and process control condition in the coloring liquid as required, tone is regulated, make canescence or light granite colors such as redness, brown, yellow, maroon, tawny, pigment can reach more than the 5mm deeply.
3, performance test: carry out water tolerance and mechanical strength test.
Adopt granite coloring technique of the present invention that the natural granite of dull coloring is carried out painted processing, its technology is simple, and raw material is easy to get, and production cost is low, and the granite color after painted is attractive in appearance, superior in quality, of many uses.The present invention is applicable to large-scale industrial production.
Embodiment one:
Iron nitrate 5 grams, Iron nitrate 18 grams, ferrous sulfate 76 grams, aluminum chloride 67 grams.Alkylbenzene sulfonate 2 grams are dissolved in the 1000ml distilled water, are mixed with the granite coloring liquid.
