Description

The manufacture craft of peculiar color pattern

The present invention relates to a kind of manufacture craft of peculiar color pattern, belong to the technical field of making imitative nature pattern.

Be subjected to water molecules motion and capillary effect, dispersate unusual changeable grain pattern can occur at water surface and diffusion motion, formed oil bloom pattern when for example people can observed gasoline be spread on the water surface in the daily life, dust are at the movement locus of globule surface imperfection etc.The grain pattern of this natural form has certain decorative value of viewing and admiring.Having proposed to utilize pigment after the dilution to be poured on the water surface through spreading or be aided with the method for the formed decorative pattern making of artificial guiding decorative paper naturally in an application number is 89103250 Chinese patent, is exactly an example wherein.The method that proposes in this patent application is owing to used the more pigment of quantity, water surface topped disperse phase thicker, can not give full play to the influence of water surface tension and water molecules motion to disperse phase, so can not form unusual changeable grain pattern, the contrast of texture and level effect can be not very good yet, can only make the decorative pattern product of approximate woodgrained paper one class in this way.Its reason is significantly, because can make pigment become fast changing in the motion of water surface after reducing disperse phase, is difficult to be used to make the decorative pattern product with being controlled.

The objective of the invention is to disclose a kind of method of making colorful unusual decoration, give full play to surface tension and pedesis influence, and make it to have favorable manufacturability surperficial disperse phase textured pattern with the grain pattern product.

Task of the present invention is to realize like this, a kind of manufacture craft of peculiar color pattern, the lines that is diffuseed to form at water surface by the colo(u)rant dispersion base material that absorbed water absorbs and makes, it is characterized in that described disperse phase is wherein a kind of of China ink or greasepaint pigment, and use and the immiscible volatile organic solvent dilution of water, be sprinkled upon then on the water surface on the sheet glass, general under 18-25 ℃ normal temperature constant temperature method, and under the shock-absorbing condition, spread, reach by the diffusion decorative pattern concrete accurately diffusion time and determine when preestablishing target, again with absorbing it on the suction base material topped water surface, after the air-dry and typing promptly; Described disperse phase dilute strength by selected raw material with the pattern-making goods under equal water quality, temperature and diffusion time pretest determine;

For pigment of different nature, select for use and the dilute strength control of solvent are key points of the present invention.Selecting for use except satisfying of solvent do not dissolved each other with water and also must have easy volatile and granules of pigments is had fabulous dispersing characteristic in these two basic demands of water than heavy water.According to test, when using the China ink material, kerosene is suitable solvent, and consumption is about half of China ink; When using greasepaint pigment, can select turps or diesel oil for use is solvent, and consumption is 1-7 a times of greasepaint pigment, the reason of thinner amount ranges broad is that the dispersing property difference of different colorants is very big, also need add hydrochloric acid in case of necessity, by 10% hydrochloric acid, consumption is the 1-2% of weight of solvent.The thinner actual amount of different pigment must adjust according to the working condition pretest, rather than theory be inferred by the target of property of raw material and pattern-making.Characteristics and shade requirement for adapting to different disperse phase add proper amount of surfactant in the water, it is effectively cooperating thinner to make to be used for the velocity of diffusion of controlling pigment, selects synthetic detergent or peach gum usually for use, and consumption is very much one to 5/10000ths.

After adopting above-mentioned manufacture craft, texture due to the diffusion of water surface material can be fixed to a kind of bright and colourful decorative pattern that is rich in artistic charm, have a close grain as hairspring, colorful dimly discernible, as if unable rosy clouds are waved in the wind, seemingly frost flower is sparkling and crystal-clear again.This pattern article is the scope of imitative grain pattern head and shoulders above, not only can be used as general decoration the such as wallpaper, board, figured cloth and uses pattern, also can be directly used on porcelain, covering of the fan, the vertically hung scroll substrate as the technology works with artistic appeal; Also can be used as the anti-fake mark pattern.

Below in conjunction with drawings and Examples, the present invention is specified.

Fig. 1 is the pinniform grain pattern that single mass colour is made.

Fig. 2 is typical greasepaint microgroove works.

Fig. 3 is the pattern works with multiple different characteristics lines.

Fig. 4 is the effect due to the artificial guiding of mass colour pattern warp.

It was a kind of spontaneous phenomenon originally that pigment molecule disperses at water surface, this pattern that forms is naturally become a kind of pattern article, and contradiction wherein is that diffusion process is slower if amount of pigment is more, " fixing " easily becomes required pattern article, and change in pattern is less thereupon; Measure lessly if disperse phase is rarer, the effect of surface water molecule is just more obvious, and change in pattern is abundant, but " fixing " nature is much more difficult, and promptly manufacture craft can become very poor.

Below with regard to shown in the description of drawings inventor how to solve above-mentioned difficulties and succeed.

Fig. 1 is the pinniform pattern of making of simple mass colour.China ink at first is scattered among the kerosene, and then is sprinkled upon on the water surface by point, and oil phase is sprawled rapidly and cut apart, and mass colour demonstrates oil phase and disperseed the formed pinniform pattern in back.

Fig. 2 is that the greasepaint of different color is transferred with turps respectively and is sprinkled upon formed microgroove shape pattern on the water surface after rare.Greasepaint has dispersing character preferably in turps, when they disperse on water surface and water stronger not wettability is arranged, so form easily microgroove shape pattern, this phase interface lines and pattern shown in Figure 1 are far from each other.

Disperse phase is subjected to multiple factor affecting in the dispersion situation of water surface, mainly comprises the wettability between disperse phase and the dispersion medium, quantitative proportion, interference such as temperature and vibrations.The constant temperature and the shockproof condition of the present invention's regulation obviously are in order to make manufacture craft have direct controllability, generally to carry out constant temperature method under 18 ℃-25 ℃ normal temperature.Higher temperature helps diffusion, also needs than the exsiccant environment simultaneously.After these external factor decisions, the ideal lines is mainly by regulating the dilute strength of pigment, yet adopt simple concentration proportioning to control, can't achieve the goal at all, usually be the different lot numbers of the same colorant of same factory, its scattering nature requires to have very big difference to dilute strength, and its performance difference of different pigment is great disparity especially.The method that the present invention adopts is that each is created used colorant under equal making temperature and other conditions, carry out dilution test earlier, with the standard of velocity of diffusion index as the dilution of control colorant, promptly in the diffusion time of regulation manufacturing conditions and regulation, this colorant diffusion decorative pattern on the test water surface reaches re-set target, and it is suitable that its extent of dilution is thought.The control that a large number of experiments show that 8-15 second can obtain good floral designs and manufacturability diffusion time.Time is too short, and processing ease is out of control because it is too many to influence the factor of diffusion effect, testing data can be not simply and actual result be equal to; A priority time difference is arranged when also considering with the topped absorption of paper simultaneously.Though the long technology controlling and process that helps of time, the level contrast of pattern reduces, and the texture interface thickens, impact effect.

Though the diffusion requirement is satisfied in over-drastic dilution sometimes, causes color too shallow,, can accelerate the spreading rate of greasepaint phase so in water, add micro-tensio-active agent in advance.The add-on of tensio-active agent is below thousandth, and emulsification and muddiness obviously have counter productive to the clearly demarcated pattern of case shell, so the use of tensio-active agent must strictly be controlled, its standard remains velocity of diffusion and pattern effect.Tensio-active agent commonly used is a peach gum, and synthetic detergent is good substitute, and the effective constituent that mainly contains wherein is tensio-active agent.

Fig. 3 is the pattern that a width of cloth has the different-style decorative pattern, and except feather figure and netted decorative pattern can form in same pattern, the greasepaint disperse phase of different diffusion properties can occur with different states at same pattern.Decorative pattern 1 is the initial state of pigment diffusion among the figure, and it is the initial state that has little time to spread, and it also has little time diffusion and just " is fixed "; Decorative pattern 2 is typical microgrooves, has the diffusion of " ideal "; Decorative pattern 3 can be thought " later stage " of spreading, and texture begins to blur.So must adjust its concentration at the diffusion final state requirement of different colorants in advance before making, or dilute strength.Terebinthine consumption can be in 1 times to 7 times range regulation of amount of pigment.If pigment is very rare, its velocity of diffusion does not still reach re-set target, and perhaps its color is too light, and is undesirable, and use hydrochloric acid to quicken the dispersion of pigment in oil this moment, and consumption is the 1-2% of quantity of solvent when with 10% hydrochloric acid.

The China ink material is easy to disperse in kerosene, so the general consumption of kerosene only needs China ink half, does not also need to add hydrochloric acid again.

Fig. 4 is the artificial effect that obtained of guiding in addition when China ink material disperse phase spreads.This effect can't occur in the greasepaint pattern, and this point is significantly different with aforesaid correlation technique.Adopt the technology of the present invention, the greasepaint diffusion of water surface is ten minutes " fragility " mutually, and the cured layer just as thin once stirring " breaking ", can't form coherent texture again.Even for the grisaille painting pattern, manually guide also only in order a kind of supplementary means of special-effect to occur, key of the present invention remains utilizes nature to spread formed lines effect.
