Abstract
The invention discloses a toner for double-component development of a high-speed electrostatic copying machine. The toner is prepared by raw materials including, by weight, from 80 to 90 parts of styrene and acrylic acid polymers, from 5 to 10 parts of carbon black, from 1 to 5 parts of Carnauba wax, from 1 to 5 parts of magnetic powder, from 0.5 to 1 part of charge control agent, from 0.5 to 1 part of fumed silica and from 0.3 to 1 part of titanium dioxide. Treatments including premixing, extrusion milling in a mixed manner, cooling, crushing, airflow crushing and classifying, micro-powder classifying and addition mixing are sequentially realized for the materials, and finally a toner product is prepared by means of sieving and packaging. The toner is applied to one type of high-speed copying machines and is universal. The styrene and acrylic acid polymers are used as main raw materials to replace existing polyester materials, and manufacturing cost is low. In addition, the toner is unique in formulation, easy in operation and low in cost, guarantees stable image density and zero bottom ash when a large quantity of files are copied continuously, and is applicable to various different high-speed copying machines with a double-component development function.
Description
Technical field
The present invention relates to the two component tone agent for developing of a kind of high speed Xerox, belong to the toner technical field.
Background technology
Along with the demand that the increase of information processing quantity and efficient improve, the digitizing of Xerox, high speed, colorize have become a kind of trend.In the application of Xeroxing, the visualization way of two components by U.S. Xerox, Japan Ricoh, Toshiba etc. for the company of main flow adopts on high speed copier, the demand of two component development hue agents of corresponding its use is also more and more.The agent of magnetic single component photomechanical printing at present has comparatively stable composition, mainly comprises resin material, carbon black, magnetic powder, electric charge agent, but also has corresponding defects.
First; At present in the world according to the adjustment of above-mentioned prescription; Though the two component shadows of preparation are many with the method for toner, one is to use seldom to high speed machines specially, because high speed copier possibly produce a large amount of negative charges in the short working time; And magnetic material of toner (generally selecting aromatic compounds) and charge control agent (generally selecting metal oxide for use) can not well cooperate, and photocopying materials bottom ash, resolution and image definition can not be met the demands; The second, existing product does not possess versatility, and existing product can not be applicable to the not duplicating type of different size, and is more single, is the type customization basically; The 3rd, adopt polyester to select as formula for raw stock, cost price and processing characteristics are bad, are unfavorable for that large-scale production and manufacturing cost reduce, and it is applied also and is restricted; The 4th, when on high speed copier, using, there is the problem that image density descends when duplicating heap file continuously.
Summary of the invention
The present invention provides a kind of high speed Xerox two component tone agent for developing, and image density is stable, no bottom ash problem.
The present invention realizes through following technical scheme:
A kind of high speed Xerox bi-component tone agent for developing is to be processed by the raw material of following parts by weight: 80～90 parts of styrene-propene acid polymers, 5～10 parts of carbon blacks, 1～5 part in Carnauba wax, 1～5 part in magnetic powder, 0.5～1 part of charge control agent, 0.5～1 part of aerosil, 0.3～1 part of titania.
Preparation method of the present invention is following:
Premixed: the above-mentioned material styrene-propene acid polymer that has measured, carbon black, Carnauba wax, magnetic powder, charge control agent are dropped into high-speed mixer mix, at first mixed on low speed is 30 seconds, then changes 90 seconds at a high speed, pauses 60 seconds; Repeat above step 2 time again, middle pause one 60 seconds;
Extrude mixing: the material that above-mentioned premix is got togather is extruded mixing through parallel dual-screw extruding machine, extrusion temperature is set at 105～150 ℃;
Cooling: above-mentioned extruded material is rolled cooling and is broken for sheet material through pair roller water cooling steel band;
Coarse crushing: above-mentioned sheet material is put into Roughpulverizer pulverize, the crushing rear material particle diameter is controlled at 0.8～1.2mm;
Jet mill grinding: the material that above-mentioned coarse crushing is good is inserted the jet mill grinding machine and is pulverized, the oarse-grained content of major control;
Micro-powder graded: as the material after the above-mentioned pulverizing to be carried out classification, remove underproof granule part, make raw meal particle size be controlled at 7.5～8.5 μ m, D50 μ m in footpath in the volume;
The outer interpolation mixes: aforementioned split pole material is dropped in the high-speed mixer with additive aerosil that measures and titania; At first mixed on low speed is 30 seconds, then changes 60 seconds at a high speed, pauses 60 seconds; Repeat above step twice again, middle pause one 60 seconds;
Sieve: use sieve shaker (screen cloth 120～140 orders) to sieve the above-mentioned material that mixes;
Packing: the above-mentioned material that sieves is packed by the appointment specification.
Said aerosil is German EVONIK system R812; Said titania is Japanese Ishihara Sangyo system ET-300W.
Beneficial effect of the present invention is: the present invention is applied on one type of high speed copier, has solved the problem of versatility.The present invention adopts styrene-propene acids polymkeric substance to be main body starting material replacement polyester material in the past, and manufacturing cost is lower.The present invention is novel, prescription is unique, easy operating, manufacturing cost are lower, and stable, the no bottom ash of image density when guaranteeing to duplicate heap file continuously is applicable to the high speed copier of various pair of component development.
