Beneficial effect in order to further illustrate the present invention,
The characteristic of the embodiment of the present invention 1~9 and the resulting carbon dust of comparative example 1~4 is measured below, specifically such as
Under:
(1) average grain diameter and sphericity
Carbon dust particles size and distribution is measured using 13 320 series laser Particle Size Analyzer of Beckman Kurt LS.
The sphericity of carbon dust is using the figure instrument measurement of American-European gram of Zhuhai.
(2) softening point temperature
Using the softening point temperature of the thermal deformation vicat softening point temperature analyzer measurement carbon dust in Dongguan the Kunlun.
(3) carried charge
Carbon dust is added in the developing apparatus of the printer of 600dpi high speed non-magnetic mono-component visualization way, exists respectively
23 DEG C of temperature, humidity 60% (N/N) environment neutralization temperature be 35 DEG C, placed 24 hours in (H/H) environment of humidity 80%, it is logical
Q/M electrification tester is crossed to measure carbon dust carried charge.
(4) storage
About 20g carbon dust is added into closed container, is taken out after placing 8h in the environment of 55 DEG C, does not destroy knot as far as possible
Structure, careful is transferred on the vibrating screen that sieve pore is 40 mesh, amplitude is set as 1.0mm, after vibration 30 seconds, measurement remains in this
Carbon dust weight on sieve, using this as the carbon dust weight of agglomeration.It calculates relative to the carbon dust weight for being initially added container, agglomeration
Specific gravity shared by carbon dust.1 sample measures 3 times, and using its average value as the index of storage, the storage characteristics of carbon dust are with the small person of numerical value
It is excellent.
The results are shown in Table 1 for the evaluating characteristics of carbon dust.
The evaluating characteristics result statistical form of 1 embodiment of the present invention 1~9 of table and the resulting carbon dust of comparative example 1~4
It can be seen that epoxy resin in comparative example 1 from the comparison of the embodiment and comparative example of upper table and although also play kind
The effect of sub- lotion, but the epoxy group in epoxy resin is active group is easy and other in carbon dust during the preparation process
The active group of component reacts, to influence the coating efficiency of core-shell structure carbon dust, cause the softening point temperature of carbon dust compared with
High and storge quality is undesirable.
It is not added with Abietyl modified epoxy resin in comparative example 2, i.e., is acted in preparation process without seed emulsion, lotion reaction
Slowly, and the coating efficiency of core-shell structure carbon dust is low, leads to that the softening point temperature of carbon dust is higher and storge quality is undesirable.
Pigment employed in comparative example 3 and silica do not carry out hydrophobically modified, and the sphericity of carbon dust is lower.
The parts by weight of Abietyl modified epoxy resin are 12 parts in comparative example 4, and carbon powder particle porosity and looseness makes the ball of carbon dust
Shape degree is lower.
On the other hand, the embodiment of the present invention 1~9 can improve the dispersion of emulsion polymerization using Abietyl modified epoxy resin
Property, the stability and mechanical property and carried charge of carbon dust are improved, softening point temperature is reduced, particle is uniform, and the sphericity of carbon dust is not
Lower than 0.96, stability is good, and structure is easy to control, and average grain diameter is 5~6.5 μm, and storage characteristics are good.
The present invention also carries out print job by the way that the resulting carbon dust of Examples 1 to 9 to be put into printer, and measures and beat
Front and back is printed, the PM2.5 around printer, the PM2.5 around printing front and back does not change as the result is shown, illustrates carbon when carbon dust prints
Powder fusing completely, will not come out with printing paper.
Above the embodiments of the present invention are described in detail, but the present invention is not limited to described embodiments.It is right
For those skilled in the art, in the case where not departing from the principle of the invention and spirit, these embodiments are carried out more
Kind change, modification, replacement and modification, still fall in protection scope of the present invention.
