Description
Technical field
The present invention relates to fields of pigments more particularly to a kind of using dimethyl silicone polymer as the natural minerals pigment colour of substrate
Poor test method.
Background technique
For pigment, color is its most important property, and a kind of performance good or not of pigment mainly sees its color
How is performance.In color management field, chromatism test is one of most important performance test of pigment.By carrying out chromatism test,
Detect pigment Δ L*, Δ a*, the numerical value of Δ b* and Δ E, so that it may accurate location of this color in color space is found,
Also it is known that the color performance in practical application of pigment.
Chromatism test is usually carried out, needs to detect pigment sample using spectrophotometric color measurement instrument, pigment is generally supported on determining
On carrier, such as silk, blank sheet of paper, wooden unit, slabstone or various printed matters.Synthetic dyestuff is generally organic pigment, absorption property
By force, it is possible to be directly applied on carrier with paintbrush, test is relatively easy.The absorption property of natural minerals pigment is weak, color is firm
Spend lower, need firmly be supported on silk or palisades with glue alum water, and Jiao Fanshui and as carrier silk or
It is the color performance that palisades all can greatly influence pigment.Meanwhile natural minerals granules of pigments is big and size distribution is uneven, matter
Measure also more much bigger than organic pigment particle, when coating also be easy to cause pigment to disperse non-uniform situation to occur.Finally, traditional face
The preparation of material sample is largely influenced by the handicraft of producer and utensil, if experimenter paints, level is not high, just
The final product quality that will lead to sample is irregular.These all can greatly influence the measurement of color difference.Therefore we need to find one
Hand is easy in kind, high yield rate, preparation is simple and is influenced lesser natural minerals pigment color difference test method by the external world.
Summary of the invention
In order to solve the above-mentioned technical problems, the present invention provides a kind of using dimethyl silicone polymer as the natural minerals of substrate
Pigment color difference test method, the present invention use dimethyl silicone polymer as pigment substrate, pass through spin coating instrument and vacuum drier
Aid in treatment, natural minerals pigment are uniformly mixed in dimethyl silicone polymer, so that sample acetes chinensis is quick, letter
It is single, accurate, pollution-free.
The specific technical proposal of the invention is: a kind of survey by the natural minerals pigment color difference of substrate of dimethyl silicone polymer
Method for testing, comprising the following steps:
1) ensure the dry free from admixture of natural minerals pigment, broken the natural minerals granules of pigments of solid using mechanical pulverizer
It is broken into natural minerals pigment powder, being crushed the time is 0.5-1min.
In step 1), natural minerals pigment large size Particle Breakage can be mentioned effectively at powder using mechanical pulverizer
Rise the loading of pigment.
2) natural minerals pigment powder obtained by step 1) is handled using standard vibrating sieving machine, then filtering out partial size is
The natural minerals pigment powder of 100-200nm.
In step 2), the pigment powder of fixed granularity is filtered out using vibrating sieving machine, it is equal the purpose is to improve pigment color
Even property facilitates pigment and uniformly mixes with substrate, is not in serious natural subsidence.
3) dimethyl silicone polymer host agent is uniformly mixed with dimethyl silicone polymer curing agent, obtains polydimethylsiloxanes
Alkane mixed liquor.
In step 3), the mass ratio of dimethyl silicone polymer host agent and curing agent is about 20: 1, and lower curing agent contains
Amount can make polymerization reaction slow down, and Chain Flexibility is larger, facilitates being uniformly distributed for granules of pigments；The usage amount of 6g or so
It cooperates with the surface plate of 6cm, the sample of formation will not influence measurement effect because of the excessively thin interference particle distribution of thickness, also not
Silicone rubber material can be wasted.
4) natural minerals pigment powder obtained by 0.3-0.5g step 2) to 5.9-6.1g dimethyl silicone polymer is weighed to mix
It is mixed in liquid, until the uneven color lump in mixed liquor completely disappears.
5) use spin coating instrument by the dimethyl silicone polymer mixed liquor spin coating of the pigment powder containing natural minerals obtained by step 4)
In the biological surface ware for being 5.5-6.5cm to diameter.
It, can using spin coating instrument since silicon rubber has self-leveling energy under unpolymerized state for liquid in step 5)
To accelerate dimethyl silicone polymer sprawling on surface plate；Meanwhile rotational time and rotation speed should not be too large, otherwise sample
Will appear concave surface influences polymerization.
6) the good dimethyl silicone polymer mixed liquor of middle spin coating is put into vacuum drier and carries out acceleration polymerization.
In step 6), under negative pressure state, the micro-molecular gas in liquid can be discharged, and guarantee final sample smoothly without gas
Bubble；Lower temperature makes reaction process mild, can gradually discharge sample interior accumulation stress, guarantee the smooth nothing of final sample
It tilts.
7) by dimethyl silicone polymer placement polymerize in step 6) under standard atmospheric conditions interior standing 1 day with true
It protects dimethyl silicone polymer polymerization to complete and thoroughly solidify, obtains the natural minerals pigment mark using dimethyl silicone polymer as substrate
Quasi- sample.
It in step 7), is further reacted on the basis of step 6), improves sample stability, guarantee to detect ring in room temperature
Polymer does not have character variation under border.
8) it is detected using spectrophotometric color measurement instrument to by the standard sample in step 7), records the Δ L* of sample, Δ a*, Δ
B* and Δ E carries out color difference analysis.
Preferably, the screening process time of the natural minerals pigment powder is 20-21min in step 2).
Preferably, in step 3), dimethyl silicone polymer host agent and the mass ratio of dimethyl silicone polymer curing agent are
19.5-20.5∶1。
Preferably, in step 5), the instrument parameter of spin coating instrument are as follows: rotational time 60-90s, rotation speed 100-
120r/min, rotary acceleration 100-120m/min2。
Preferably, in step 6), reaction condition in vacuum drier are as follows: reaction temperature is 60-70 DEG C, and the reaction time is
12-14h, vacuum degree are -25~-2311Hg。
It is compared with the prior art, the beneficial effects of the present invention are:
1, the present invention uses dispersible carrier of the dimethyl silicone polymer as pigment.Dimethyl silicone polymer has high light transmission
Property, it is possible to prevente effectively from the misalignment as caused by Jiao Fanshui and silk quality problem in conventional mineral pigment sample, hence it is evident that
Improve detection accuracy.
2, dimethyl silicone polymer used in the present invention has flexibility as high polymer, can pass through Self-leveling in polymerization
Performance forms open and flat smooth flexible surface, detector can be fitted closely with sample it is seamless, it is possible to prevente effectively from glue
Alum water cure forms fold and pigment dispersion is not respectively formed detection error caused by pit.
3, the work of sample preparation is converted into pure experiment detection means from handicraft production by the present invention, has evaded biography
The step of silk preparation, pigment reconciliation, classical Chinese painting on silk brush etc. need to test operator's drawing techniques in system sample preparation procedure, avoids
Because of error caused by personnel's operation.
4, operation of the present invention is simply easy to get started, and sample preparation is quickly high-efficient, and finished product beauty is easy to detect.
