Abstract

The invention discloses an additional composite function material for an electrostatic developer. The additional composite function material is prepared by raw materials including, by weight, from 50 to 70 parts of magnetic powder, from 8 to 15 parts of silicon oil, from 1 to 5 parts of zinc stearate and from 10 to 15 parts of fumed silica, and the materials are sequentially fed into a high-speed mixer to be mixed according to the proportions, so that the additional composite function material is obtained. The additional composite function material is used for the electrostatic photocopying technology, can be used with single-component silica, effectively prevents a tone agent from being adhered with a photosensitive drum during usage, and solves the problem of hollow printed or photocopied images and texts. In addition, the problem of image rippling due to over thick tone agent accumulated on a magnetic roller can be accessorily solved when the additional composite function material is used in a magnetic single-component system, and the quantity of electricity of the tone agent can also be regulated.

Description

Electrostatic developer is with adding composite functional material outward
Technical field
The present invention relates to a kind of electrostatic developer with adding composite functional material outward, belong to developer and use the additive technical field.
Background technology
In the application of Xeroxing, developer is topmost consumable material.The operate as normal of each function system of developer and duplicating machine or printer is all interrelated, and promptly developer and Xerographic printer need very coupling.
In the prescription of existing developer; Resin, wax, CCA, colorant etc. are the basic functions materials; In recent years, along with the equipment of Xeroxing is more and more faster, in order to satisfy the needs of machine; Require the particle diameter of toner more and more littler, require also increasingly high its charging property, keeping quality, flowability and spatter property etc.As, charging property can be that electropositivity can be an electronegativity also, select for use can in the electrical developer raw material of copier.
According to above-mentioned requirements; Developer formuia is adjusted; Existing disposal route is generally the adding additive; The additive that adds is an one-component silicon dioxide, is improved to being used of many materials such as aerosil, gaseous oxidation titanium, gaseous oxidation aluminium, strontium titanates, stearate, PMMA afterwards again.Wherein the functional material addition of some component is few, is not easy in the system of evenly spreading to.Simultaneously comprehensively lack auxiliary solution and means aspect the adjustment at photosensitive drums spatter property, image outline letters, magnetic property and chargeding performance.
Summary of the invention
The present invention provides a kind of electrostatic developer with adding composite functional material outward, and itself and aerosil are used jointly, effectively overcomes the problem of inconvenience of homogenous material use in the past and dispersive property difference, has the adjusting charge effect simultaneously.
The present invention realizes through following technical scheme:
A kind of electrostatic developer is to be processed by the raw material of following parts by weight with adding composite functional material outward: 50~70 parts in magnetic powder, 8~15 parts of silicone oil, 1~5 part of zinc stearate, 10~15 parts of aerosils.
Said magnetic powder is U.S.'s Lockwood (Rockwood) system: TB5625.
Said silicone oil is Dow corning (Dow Corning) system: dimethyl silicon oil.
Said zinc stearate is U.S.'s good fortune high post (Ferro) system: 44HS.
Said aerosil is German EVONIK system: R202.
Preparation method of the present invention is following:
Batching: get 50~70 parts in magnetic powder, 8~15 parts of silicone oil, 1~5 part of zinc stearate, 10~15 parts of aerosils;
Mix: will the above-mentioned material that has measured drop into high-speed mixer successively by the order of magnetic powder, silicone oil, zinc stearate and aerosil and mix, at first mixed on low speed is 15 seconds, then changes high speed 60 seconds, pauses 60 seconds; Repeat above step twice again, middle pause one 60 seconds;
Packing: the above-mentioned material that mixes is emitted by specifying the specification packing.
Beneficial effect of the present invention is: product of the present invention can be used with one-component additives such as aerosils; Addition is 5~30%; Prevent that effectively toner from adhering to photosensitive drums in using, solve printing or copy image and the hollow phenomenon of literal, in the magnetic single component system, can also assist solution toner magnetic roller to pile up the blocked up image waviness phenomena that causes, the carried charge to toner also has regulating action simultaneously.
A kind of effective additive that can be used as except that aerosil is selected to use, and effectively having overcome in the past, homogenous material uses inconvenience and adding proportion to bring the bad problem of dispersion very little.
