Description
Technical field
The present invention relates to technical field of polymer materials, particularly relate to a kind of making high-speed digital duplicator carbon dust main raw material---high-definition digital photographic developer special polymer content of wax resin and preparation method thereof.
Background technology
High-definition digital photographic developer special polymer content of wax resin is the main raw material producing high-speed digital used in copy machines carbon dust.At present, the resin that on market, high-speed digital duplicator carbon dust uses adopts the vinylbenzene, Butyl acrylate and the dibutyl maleinate resin that suspend and make, and molecular weight distribution is little, and melting index is high, and high temperature not easily dissolves.The high-speed digital duplicator carbon dust made with this resin, in use easy roll banding and fixing difference, can produce a large amount of useless powder, and transferring rate is lower, use cost is high, not only taste weight, and pollutes the environment.
Summary of the invention
The object of the invention is to overcome existing defect, a kind of high-definition digital photographic developer special polymer content of wax resin is provided, with the high-speed digital duplicator carbon dust of this production of resins, there is comparatively wide molecular weight distribution, adding polymer content can meet anti-offset resistance, excellent melting behaviour is had under low-temperature fixing, not roll banding, fixing good, useless powder can not be produced, not only can improve the transferring rate of high-speed digital duplicator carbon dust, reduce use cost, not only tasteless, also can not to environment.
Another object of the present invention is to provide the preparation method of a kind of high-definition digital photographic developer special polymer content of wax resin.
Above-mentioned purpose of the present invention is realized by following technical solution:
The invention provides a kind of high-definition digital photographic developer special polymer content of wax resin, the weight part of its constitutive material is:
Present invention also offers the preparation method of a kind of high-definition digital photographic developer special polymer content of wax resin, comprise the following steps:
(1) vinylbenzene of 70-85 part, the Butyl acrylate of 17-23 part, 3-5 part methymethacrylate and 3-5 part isooctyl is taken, pumping into header tank stirs after 15-20 minute, add the ditertiary butyl peroxide of 2-4 part, the tert-dodecyl mercaptan of 0.1-0.3 part and the Vinylstyrene of 2-4 part again, continue uniform stirring, make compound for subsequent use;
(2) add the solvent xylene of 70-85 part and the PP wax of 3-8 part in a kettle., spacer carries out electrically heated simultaneously, continues uniform stirring, is warmed up to 135-140 DEG C;
(3) start to drip with the compound made in step (1), control 4 hours and drip off, then be incubated 4 hours, insulation terminates normal pressure 2 hours again;
(4) normal pressure terminates, and starts to vacuumize, de-dimethylbenzene, time 3 hours, and during de-dimethylbenzene, bottom valve must be heated in heating jacket preheating;
(5) the material pressurized air in reactor is released;
(6) with pulverizer, the work in-process crossed through cooling process are pulverized;
(7) with 120 eye mesh screens, the work in-process through pulverizing being sieved, making its particle diameter be 0.15-0.3 μm, high-definition digital photographic developer special polymer content of wax resin can be obtained.
Adopt such scheme, have the following advantages:
Owing to containing PP wax in a kind of high-definition digital photographic developer of the present invention special polymer content of wax resin, can meet anti-offset resistance, low-temperature fixing anti-caking effect, add Vinylstyrene as linking agent simultaneously, improve resin polymer ratio, there is excellent melt performance in low-temperature fixing, good dispersity, image stabilization is beautiful, the manuscript printed not fugitive color.Useless powder would not be produced with in the high-speed digital duplicator carbon dust high-definition digital photographic developer special polymer content of wax resin use procedure of this production of resins.Therefore with the high-speed digital duplicator carbon dust resin of production of resins of the present invention, not only transferring rate is high, use cost is low, not only tasteless, also can avoid environmental pollution.
Because resin of the present invention adopts solvent method to produce, wherein separant is solvent xylene, the resin content of wax that reflects can be made even, and separant solvent xylene can recycle, and the high-speed digital duplicator carbon dust standby by this resin-made is not only evenly mixing, without white tiles, compatible good, carried charge is even, and it is beautiful to have printing manuscript lovely luster, good resolution, level advantages of higher.
