Description
Method and the used dyestuff of the present invention for rock is changed colour.The alleged rock colour-changing method of the present invention also can be called rock colorant match method, perhaps rock colouring method, expression by present technique with former canescence rock, or light grey rock, or Dark grey rock, or other secondary color rocks become other color.
WPI has published the summary of BR8803006, and the technical process that discloses rock dyeing is as follows: a) with rock cutting, shaping, polishing; B) heat drying slowly, temperature reaches 80～220 ℃; C) be impregnated in the dyeing container of coloring agent and mechanical cycles and dye; D) cleaning, drying.The essence of this technical scheme is that with the surface colors color of rock, and rock interior still is original color.
Rock with granite, gabbro, diabase, marble and so on of firm, wear-resisting, corrosion resistance properties is commonly used for construction material, the facial ornament material on body of wall or floor, and the material of carving various article, wherein have people and like that very the above-mentioned rock resource quantity of natural colour is few, a large amount of exist but do not have a color that people like.Above reason causes not only that non-people like color stone material and people extensively to like the greatly different price difference between the kind in building, facial ornament material and the artistic carving material, has also had a strong impact on the extensive utilization of non-people being liked the color rock.
The objective of the invention is to, utilization rock colour-changing technology makes non-people like the color rock to have the color that people like, so as to improving its value of the product and utilizing resource more widely.
Method of the present invention comprises cutting rock, the stone material desired area is polished, contaminates, stone material is put into container, inject and contaminate agent, in certain temperature range, keep certain hour, cleaning and drying steps, this method can be divided into material preparation step 1 (Fig. 1), the step 2 of changing colour and fine finishining step 3, travel direction 10 between step, it is characterized in that: A. cuts into plate with the rock of desiring to change colour or engraving is shaped in material preparation step 1; B. the step 2 of changing colour is divided into acid treatment step 4 (Fig. 2), and the stone material of desiring to change colour is put into container, injects acidizer, and acidizer is the etching acid solution of concentration 2～25%, handles 10～60 minutes; Cleaning step 5 cleans the stone material water after acid treatment, removes remaining acidizer; Contaminate step 6, to put into container through acid treatment, the stone material that cleaned, inject and contaminate agent, in normal temperature～90 ℃, pressure is to keep under 0.5～1MPa 10～30 hours, contaminate agent under 500 ℃, can carry out decomposition and inversion, generate stable performance under field conditions (factors) and have the salt saturated solution of the oxide of color; Decomposition and inversion step 7 is put into the decomposition and inversion stove to the stone material after contaminating, and is heated to 100～450 ℃, keeps 30 minutes～4 hours; With cooling step 8, the degree of step or following road step after will being cooled to through the stone material that decomposition and inversion is crossed to enter; Travel direction 10 between each step; C. required size is polished and cut into to fine finishining step 3 to the desired area of chilled stone material.Five steps in the above-mentioned step of changing colour can be carried out once respectively in order; Perhaps after proceeding to cooling step in order, will contaminate step, decomposition and inversion step and cooling step again and repeat one in order to several times; Perhaps will contaminate step and acid treatment step and merge into a step and carry out, and then carry out cleaning step, decomposition and inversion step and cooling step.Contaminate agent with the dyestuff preparation, have color resolving into below 500 ℃ and 500 ℃, and the salt saturated solution of the oxide of stable performance.Dyestuff commonly used has ferrous sulfate, mercuric nitrate, potassium permanganate, plumbi nitras, ferric sulphate, nickel nitrate, manganese nitrate, chromic nitrate, chromium acetate, ferric nitrate, ferric dichromate, copper nitrate.These dyestuffs both can use separately, also can mix use, also can be respectively applied for same stone material, carried out colorant match.As long as before the step of changing colour,, can dye pattern at pattern blank background place coating acid-resistant paint.The material that can be used as acid-resistant paint has: pitch, plastic-blasting, epoxy resin, acid-proof paint, acid-proof printing ink, and the mixture of above-mentioned any two kinds of materials or two or more materials.
The present invention has following advantage: the present-color material that rock colour-changing produced is a colored oxide, has goodish stability under field conditions (factors), can stand ultraviolet irradiation, variations in temperature, rainwater immersion, mechanical friction for a long time and keeps color constant; It is more even to change colour, and gos deep into rock interior, can match in excellence or beauty with lithotome; Equipment does not have specific (special) requirements, the small investment of founding the factory; Processing step is simple, grasps easily; The used source material source is wide, cheap; No discharging of waste liquid, anti-pollution investment that must be not a large amount of; The product processing charges is low.
Fig. 1 is the rock colour-changing process sequence diagram.Fig. 2 is rock colour-changing step process figure, and each step of order is carried out once respectively set by step.Fig. 3 is rock colour-changing step process figure, after order proceeds to cooling step set by step, repeats to contaminate step, decomposition and inversion step and cooling step one more in order to for several times.Fig. 4 is rock colour-changing step process figure, with acid treatment step and contaminate step and merge into a step and carry out, carries out cleaning step, decomposition and inversion step and cooling step then.
Embodiment 1: the sheet material that light gray or canescence granite are cut into is put into container, add concentration and be 20% etching acid solution, at normal temperatures, carry out acid treatment step 4 (Fig. 2) half an hour.Travel direction 10 set by step carries out cleaning step 5 then.Contaminating step 6 again, drop in the saturated copperas solution, is that 60 ℃, pressure are to contaminate 12 hours under the 0.5MPa in temperature, carries out decomposition and inversion step 7 again, puts into the decomposition and inversion stove, is 400 ℃ of following decomposition and inversion 2 hours in temperature.After carrying out cooling step 8,, and be cut into the required size size, be red granite (body of wall, ground) facial ornament sheet material the desired area polishing.
