Description
Technical field
It is after being related to a kind of steel mill's scale oxide specifically the present invention relates to a kind of steel mill's scale oxide aftertreatment technology
Treatment prepares the technique of high-performance compressor yielding rubber admixture, belongs to powder technology field.
Background technology
The main application of steel mill's scale oxide now is still the electronic component for preparing permanent-magnet ferrite and correlation
And the iron powder of powder used in metallurgy is prepared, and it is fewer always for consumption in the application of rubber materials, also it is not downstream electrical
Device, payes attention to including the producer such as air-conditioning and refrigerator.As economy enters under new normality, the especially background of each industry production capacity surplus,
Performance is improved for basic raw material, the cry of reduces cost is also increased resolutely.Traditional rubber admixture includes calcium carbonate, pottery
Soil, barium sulfate and talcum powder etc., for improving performance or reduces cost, in addition with many natural inorganic mineral powder body materials
Gum filler is can serve as, such as the dolomite containing magnesium carbonate, the wollastonite containing calcium silicates, the barite of containing sulfate, gypsum contain
The stone of amorphous carbon is black, coal dust and other siliceous konilite diatomite, asbestos, pyrophyllite, gangue, oil shale, flyash,
Attapulgite, red mud etc..Because iron scale pulverized powder is than great, the cheap green grass or young crops for receiving domestic compressor damping rubber user
Look at, but because it is steel mill's hot rolling accessory substance, thus carry no weight, quality is simultaneously unstable, high signal area similar with foreign countries
Also there is certain mass gap.
The content of the invention
It is an object of the invention to provide the invention aims to provide one kind property high is prepared using steel mill's scale oxide
The technique of energy compressor damping rubber admixture, for defect and the market demand existing for prior art, there is provided low cost,
Low energy consumption, comprehensive utilization and product quality are quite or partial properties are better than the external technique for being similar to admixture.
To improve the performance of scale oxide admixture, the method main method that the present invention is taken is to reduce particle diameter, improve
Particle diameter distribution and removal of impurities.
In order to realize above technique effect, the present invention is to be achieved by the steps of：
S1, scale oxide is statically placed in degreaser after, taking-up is dried, and obtains refined scale oxide；It is treated with degreaser
Afterwards, it is beneficial to improve the pine dress ratio of product.
S2, by S1 refined scale oxide input ball mill in carry out ball milling, obtain ball milling rear oxidation iron scale；
S3, ball milling rear oxidation iron scale in S2 is carried out magnetic separation, reject namagnetic substance, sieving is left and taken in sieving；
S4, the sieving in S3 is carried out into classification sieving, leave and take residue on sieves at different levels and last sieving；
S5, residue on sieve at different levels in S4 and last sieving are mixed in proportion.
Wherein, in step S1, the degreaser is NaOH, sodium carbonate, tertiary sodium phosphate, sodium metasilicate, sodium pyrophosphate, Asia
Two kinds or two kinds in sodium nitrate, borax, disodium hydrogen phosphate, sodium acid carbonate, alkyl phenol polyoxy ether, neopelex
More than.Its ratio is the known technology in the art.
Wherein, it is described to dry effect to control scale oxide moisture content for 3-10% in step S1.
Wherein, in step S2, the ball milling condition is the steel ball filling rate of ball mill 30~40%, grinding temperature 30~
60℃。
Wherein, in step S3, the sieving refers to be sieved with 80 mesh.
Wherein, in step S4, the classification sieving refers to carry out classification sieving with 200 mesh, 460 mesh, 650 mesh, 800 mesh.
Wherein, in step S5, the ratio is 200 screen residue 0.5-1%, 460 screen residue 1- by weight proportion
2%, 650 screen residue 2-2.5%, 800 screen residues 3%, remaining as 800 mesh sieving materials.Under this proportioning, it is beneficial to pine
Fill the raising of ratio.
Wherein, in step S5, the incorporation time is 1-3 hours.
The beneficial effects of the invention are as follows：
1) more original iron scale admixture ratio, hence it is evident that reduce particle diameter, and make particle diameter distribution more reasonable, while improve loose dress
Than, and make the particle diameter distribution of acquisition material more stable；
2) more original similar applications admixture is compared, and on the premise of consumption is reduced, maintains the work of lifting rubber proportion
With；
3) because the iron scale admixture particle diameter of the technique is thinner, particle diameter distribution is more reasonable, and microscopic appearance is more mellow and fuller, therefore institute
Prepared rubber surface is more smooth, and damping effect is more preferable；
4) with old iron scale technics comparing, make it possible to obtain high signal area under low cost.
Scale oxide admixture D50 particle diameters are obtained in 4-6um by this method, scale oxide Fe contents are more than 74%,
Pine dress compares 2.2-2.6g/cm3Between, and former iron scale technique admixture and other similar applications admixture ratios, with low cost, ring
Border influence is low, and it is high to obtain material rate, good dispersion, particle diameter distribution more reasonably advantage；Although being improved on cost, to subtracting
Shake rubber performance boost effect be it will be apparent that, the technique have economic worth higher.
