Abstract
The invention relates to material formula for preparing an anisotropic permanent ferrite injection molding mother batch. A preparation method of the material formula comprises the following steps of: uniformly mixing 88.0-91.0 percent by weight of ferrite powder with 0.01-0.50 percent by weight of water; uniformly mixing 0.01-0.50 percent by weight of additive with 9.0-12.0 percent by weight of nylon 6 powder; uniformly mixing 0.01-1.0 percent by weight of coupling agent with 0.01-0.80 percent of isopropyl alcohol; mixing the three mixtures in sequence; and putting the mixture into a drying oven for drying, taking out, and cooling to normal temperature. The method has the advantages: the defects of various plastic and magnetic products during injection molding can be overcome completely, the fluidity of the anisotropic permanent ferrite injection molding mother batch can be remarkably improved, the thermal friction coefficient between the ferrite/nylon 6 and a molding machine screw is reduced, the parameter value of each magnetic performance of the permanent ferrite injection molding mother batch is increased, and the quality requirement of high magnetic performance on an injection-molded magnetic product is met.
Description
Technical field
The present invention relates to prepare material, relate in particular to a kind of anisotropy permanent-magnet ferrite injection mould master batch and prepare material prescription about different in nature permanent-magnet ferrite injection mould master batch.
Background technology
Magneticsubstance is the important foundation functional materials of electronic industry, is widely used in industrial circles such as computer, electron device, communication, automobile and aerospace.Along with the fast development of world economy with science and technology; Injection molding technology has been applied to the industry-by-industry of modern industry; Yet brought into use injection molding technology to produce ferrite permanent magnet as far back as people in 1980, and ferritic injection technique development of later stage is very fast, has stepped into industrialization at present.
The current era electronic information technology realizes develop rapidly, has higher requirement at aspects such as complex-shaped degree, dimensional precision, miniaturization, lightness, intellectualities to magneticsubstance and magnetics in market.Permanent magnet material is as an important component part of magneticsubstance; The bonded ferrite material price is cheap and have a characteristic of non-conductive property; Thereby be applicable to the equipment of high frequency magnetic field; Different plastics is that base material is processed rigidity or flexible product, and the design of product is wanted flexibly than other classification magnet with manufacturing.Wherein each anisotropy is meant the crystalline anisotropy promptly along the different directions of lattice, and the periodicity and the density degree of atomic arrangement are not quite similar, and causes crystal also different in the physics-chem characteristic of different directions thus, is the crystalline anisotropy.Although had ferrite injection mould master batch miscellaneous in the market; But the product of most producers still has more defective and drawback in actual production; For example flowability and magnetic are relatively poor, variously mould the magnetic product is not enough to satisfy each side such as shape, size, model, intellectuality when injection moulding requirement.For this reason; In order to explore and to overcome various defectives; The mode that prior art adopted comprises the ferritic production technique of change, changes ferrite material powder particles, improves manufacturing process, the input ratio of adjusting each component or blending means or order by merging and adjustment binding agent etc.; Although obtained progress to a certain extent, but still do not obtain significant effect.
Summary of the invention
To above defective; The present invention provide a kind of possess accurate manufacturing dimension, consistency of product strong, help that complex-shaped formed product, mechanicalness and erosion resistance are strong, density is little, the anisotropy permanent-magnet ferrite injection mould master batch that can improve the product over-all properties prepares material prescription; Through improving the mobile of permanent-magnet ferrite injection mould master batch and improving on the basis of magnetic parameter value, improve other relevant over-all properties simultaneously.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
A kind of anisotropy permanent-magnet ferrite injection mould master batch prepares material prescription, and its preparation method mainly comprises:
(1) at first, be that the ferrite material powder of 88.0%-91.0% and the water of 0.01%-0.50% mix with weight fraction, with for use;
(2) be that the additive of 0.01%-0.50% and the nylon 6 material powder of 9.0%-12.0% mix with weight fraction;
(3) be that the coupling agent of 0.01%-1.0% and the Virahol of 0.01%-0.80% mix with weight fraction;
(4) secondly, successively step (1), (2), (3) are mixed;
(5) last, will insert oven for drying by the material that step (4) uniform mixing draws, temperature can be set according to actual different situations flexibly, and the oven dry back is taken out and is cooled to normal temperature.
The beneficial effect that anisotropy permanent-magnet ferrite injection mould master batch of the present invention prepares material prescription is: this method is main material, be the permanent-magnet ferrite injection mould master batch that binding agent, the additive that reaches certain deal are extruded through the twin-screw mixer machine to belong to thermoplastics (being polymeric amide-nylon 6) with injection ferrite material powder; Can remedy and overcome the various many disadvantages of magnetic product when injection moulding of moulding fully with not enough,, size complex-shaped to satisfy accurately, the requirement of each side such as miniaturization, lightness, intellectuality; Can not only obviously improve the flowability of anisotropy permanent-magnet ferrite masterbatch; And can reduce the later stage produce in the temperature of injection moulding; Thereby reduce the thermal friction coefficient between ferrite/nylon 6 and the shaper screw rod; Prevent nylon 6 oxidation at high temperature and decomposition; The crucial parameter value that a bit then helps improving permanent-magnet ferrite injection mould master batch each item magnetic property has the quality requirements and the hope of high magnetic characteristics to realize the magnetic product after the injection moulding.
Embodiment
The described anisotropy permanent-magnet ferrite of embodiment of the invention injection mould master batch prepares material prescription, and its preparation method mainly may further comprise the steps (setting the gross weight mark is 100%):
(1) at first, be that the ferrite material powder of 88.0%-91.0% and the water of 0.01%-0.50% mix with weight fraction, with for use;
(2) then, be that the additive of 0.01%-0.50% and the nylon 6 material powder of 9.0%-12.0% mix with weight fraction;
(3) be that the coupling agent of 0.01%-1.0% and the Virahol of 0.01%-0.80% mix again with weight fraction;
(4) secondly, successively step (1), (2), (3) are mixed;
(5) last, will insert oven for drying by the material that step (4) uniform mixing draws, temperature can be set according to actual different situations flexibly, and the oven dry back is taken out and is cooled to normal temperature.
