Multiple performance tests of blue oil painting composite pigment
I, study on the stability
10 weight are separately added into the blue oil painting composite pigment of above-mentioned all examples (including embodiment and comparative example)
The white oil (being used as solvent naphtha) of part, is then sufficiently stirred in high-speed shearing machine, and it is outstanding to obtain the uniform blueness of form
Mixed liquid, placement are kept in dark place at room temperature, so as to investigate the stability of different times, the result is shown in table 1 below.
Table 1
Note:Wherein " AAA " represents solution morphology and color and luster uniformly, without caking without layering;" AA " represent solution color and
Form exists visually distinguishable uneven (such as slight lower part color is slightly deep, and top color is slightly shallow), but without flocculate without
Layering;" A " represents that obvious layering occurs in solution, but without flocculate;" A* " represents obvious layering occur, and also there are bright
Aobvious flocculate.
Blue oil painting composite pigment of the invention has best ordinary temperature stability as seen from the above table, and when some groups of change
During part, then:1st, when the species for changing nitrogen heterocyclic ring inferior amine salt in the preparation of modified graphene, 1- benzyls -3- is especially replaced with
During double (fluoroform sulphonyl) inferior amine salt of methylimidazole, stability is caused to be significantly reduced, especially 80 days whens occur point
Layer and caking, this should be due to somewhat changing so as to result in the change of its electronegativity in nitrogen heterocyclic ring inferior amine salt structure,
And then the modification performance that result in graphene decreases, and is significantly reduced the antistatic property of modified graphene, from
And it result in the appearance of flocculate;And when (fluoroform sulphonyl) inferior amine salt double for N- normal-butyl-N- methyl piperidines, at 80 days
Also occur visual distinguishable uneven.2nd, when changing the species of coupling agent, occurred visual distinguishable inequality at 80 days
Even, coupling performance decreases.3rd, influence of the selection of activating agent to stability is also very big, such as D16-D18 was at 80 days
There is obvious layering (influence of emulsifiability and surface-active), so that most preferably pentaerythritol triacrylate;4th, it is right
For permeation promoter, the effect of sodium diethylhexyl sulfosuccinate will be significantly better than sulfamic acid sodium, it in system to depositing
The modification at a large amount of inorganic interfaces have and best invade profit effect.
II, oil painting weatherability are investigated
Respectively using above-mentioned all examples (including embodiment and comparative example) blue oil painting composite pigment make painting canvas or
The strip (and farthest ensureing the identical of pigment layer thickness) of length and width all same is drawn on paper, fully after drying completely,
Under 80 DEG C and relative humidity 35%, using the fluorescent lamp that power is 200W according to shining 50 days, weatherability investigation is carried out with this, respectively
Flatness, range and color uniformity are investigated, the result is shown in table 2 below.
Table 2
Wherein, " smooth, smooth, uniform color " is optimal effectiveness;" occasionally having crackle " refers to that there are seldom crackle (often to put down
Have 1-3 roots crackle different in size in square decimetre), " occasionally having bubbling " refers to that there are seldom bubbling (in every 5 × 5cm averagely to have
2-4), " occasionally having aberration " refers to that " having crackle " refers to that there are less to split there are the difference in some visual distinguishable colors
Line (averagely has 4-8 roots crackle different in size) in every 5 × 5cm, " a small number of bubblings " refers to that there are less bubbling (every 5 × 5cm
Inside averagely have 5-10), " compared with multiple cracks " refer to that there are more crackle (in every 5 × 5cm averagely to have different in size more than 8
Crackle), " more bubbling " refers to that " color and luster is thin out " refers to there are more bubbling (in every 5 × 5cm averagely be more than 10)
The blue shade naked eyes of D25-D27 on the whole are distinguishable to want the light color and luster in L1-L3, and there is " whiting " phenomenon, " color and luster is light " is
The blue shade naked eyes of finger D28-D30 on the whole are distinguishable to want the light color and luster in D25-D27, and " whiting " phenomenon becomes apparent.
It can be seen from the above that the blue oil painting composite pigment of the present invention has best weatherability, and when changing some components,
Then:1st, when modification infusorial earth does not carry out acid treatment and alkali process, then there are bubbling, this should be non-resistance in its minim channel
Caused by the expansion that sour or non-alkaline-resisting impurity is produced with the extension of high temperature and time;2nd, change when in the preparation of modified graphene
During the species of nitrogen heterocyclic ring inferior amine salt, crackle and aberration are generated, this is equally due to the graphene for stability and resists quiet
Caused by Electric property modification deficiency;3rd, when changing the species of coupling agent, there are more crackles and bubbling occur, it was demonstrated that its idol
Connection effect has reduction;4th, the change of activating agent and permeation promoter, causes bubbling occurred, it was demonstrated that for inorganic matter and inorganic matter it
Between interface modification and surface-active decrease;5 and the change of curing agent, have significant impact the most for weatherability,
Best technique effect could be obtained when being only 4,4'- diamino bicyclic hexyl methane, and other curing agent cause to occur
More crackles and bubbling, its curing performance have significant reduction;6th, when phthalocyanine blue does not carry out microencapsulation processing, then lead
Cause overall color and luster thin out, initial blue color can not be kept for a long time, this is because phthalocyanine blue pigment particulate is directly exposed in high temperature high fever
External environment condition in and photochromic and weather stain easily occurs, and carry out microencapsulation processing then overcome the defect completely;
7 and when rare-earth complex Tb (III)-TTHA is not present, weatherability is very poor, this is because when there are during Tb (III)-TTHA,
Even if strong illumination also can produce light absorbs by electron transition;And when it be not present, then produced more because of strong illumination
Serious photochromic and weather stain.
III, environmental safety are investigated
The strip for the identical length and width that each pigment in II is made is (so as to ensure that each dosage of pigment is tried one's best phase
Together), then it is sealed respectively, is aided with the natural lighting of normal alternation of day and night.
30 days mass contents for then measuring volatile organic matter (VOC) in each sealing container, the measurement means of the VOC
It is the e measurement technology of very known organic volatile, those skilled in the art can carry out suitably selecting and determining, herein not
It is described in detail again.
Concrete outcome see the table below 3, wherein every group be each pigment included in it average value, with the content of L1-L3
On the basis of (be set as 100), other pigment obtain respective content balance value in contrast.
Table 3
It can be seen from the above that the blue oil painting composite pigment of the present invention has minimum low VOC burst sizes, and:1st, D1-D6
VOC content has significant increase, this is because when not carrying out bronsted lowry acids and bases bronsted lowry processing in succession, causes to exist in diatomite gap a large amount of
Impurity, prevent follow-up TiO2Duct absorption and formed, optimal photocatalysis Decomposition effect can not be carried out;2nd, coupling agent and
The change of curing agent, also causes VOC content to have significant increase, this should be because optimal coupling and curing can not be realized,
Cause not being coupled largely and generate slow decomposition with uncured organic matter, so as to discharge unwanted volatile.
IV, wearability are investigated
Each pigment in II is made to the strip of identical length and width, fully after drying completely, wearability test is carried out, to same
Group sample is tested under identical measurement standard (750g/500r), and each different groups repeat three times, to take it average
Value (g) is used as measured value, and the result is shown in table 4 below:
Table 4
As can be seen here:1st, when coupling agent changes, wearability significantly reduces, it was demonstrated that its coupling strength and granularity, which have, significantly to be subtracted
It is weak;2nd, influence of the change of curing agent to wearability is maximum, and when using other curing agent, wearability has drop the most obvious
It is low.
The investigation of preparation method
In order to investigate the influence of the substep of coupling agent in step S3 and S4 addition, following investigation has been carried out.
Comparative example 1-3:(do not add in step s 4 in addition to all coupling agents are disposably added in step s3
Enter), other operations are constant, so that repetitive operation embodiment 1-3, sequentially obtains contrast preparation example 1-3, by gained blue oil
Draw composite pigment and be sequentially named as DL1, DL2 and DL3.
Comparative example 4-6:(add in addition to all coupling agents are disposably added in step s 4 i.e. not in step S34
Enter), other operations are constant, so that repetitive operation embodiment 1-3, sequentially obtains contrast preparation example 1-3, by gained blue oil
Draw composite pigment and be sequentially named as DL4, DL5 and DL6.
According to above-mentioned I-IV same procedure carry out study on the stability, oil painting weatherability investigate, environmental safety investigate and
Wearability is investigated, and as a result see the table below 5-8 respectively, in order to become apparent from intuitively being contrasted, the identical result one of L1-L3 is arranged side by side
Go out.
Table 5
It can be seen from the above that when disposable all additions coupling agent in step S3 or S4, stability at 80 days is caused to have
Reduced, this proves that substep carries out coupling and can obtain best performance for stability.
Table 6
It can be seen from the above that when in step s3 it is disposable all add coupling agent when, cause to generate " occasionally having bubbling " (should be
In step s3 caused by coupling excessively), and disposably add in step s 4 then without influence.
Table 7
It can be seen from the above that when disposable all additions coupling agent in step S3 or S4, VOC content is caused to have slight liter
It is high.
Table 8
As can be seen here:When disposable all additions coupling agent in step S3 or S4, wearability is caused to have obvious increasing
Greatly, best coupling effect and coupling strength can be produced this again demonstrate coupled stepwise so that its have it is most excellent
Wear-resisting property.
