On be stirred, control modification temperature, carry out filtration drying and obtain modified antimony oxide, the purification temperature is 80 DEG C, institute
Modification temperature is stated for 50 DEG C.
By following test method have studied acid/absolute ethyl alcohol, temperature, impact
。
As seen from the above table, the value of VH: V absolute ethyl alcohol is too big in mixed solvent or too little is all unfavorable for that antimony oxide is carried
The raising of pure yield.Because making solvent and making hydrolysis of the solvent to antimony oxide with absolute ethyl alcohol have different impacts with dense H,
The environment of antimony oxide hydrolysis is different, and the yield that purify can antimony oxide is different.Test result indicate that, VH: V is anhydrous
Ethanol optimum value is 1: 1.
As can be seen from the above table, reaction temperature to antimony oxide purification yield impact it is very big, temperature it is too high or
The too low purification for being all unfavorable for antimony oxide.In experiment of single factor, when the temperature increases, antimony oxide precipitation is rapid
Produce.This is because with the rising of temperature, the speed for generating nucleus is accelerated, the corresponding quickening of rate of crystalline growth.When
When reaction temperature is higher, the solubility of antimony oxide is larger, and the relative saturation degree of precipitation particles is less, and this just makes crystal
Formation speed more than crystal nucleation rate, easily generate the crystal of greater particle size, be unfavorable for less three oxidation of particle diameter
The generation of two antimony, and the less antimony oxide anti-flammability of particle diameter is preferable;When temperature is too low, it is unfavorable for the dissolving of crystal,
Can not uniformly dissolve in a solvent, hydrolysis will certainly be affected.When only reaction is in suitable temperature, the yield of Sb2O3
Maximum can just be reached.It is thus determined that optimal reaction temperature is 80 DEG C.
As can be seen from the above table, the catalytic effect of modified antimony oxide powder is significantly lower than three oxygen before modified
Change two antimony powder bodies, illustrate that invalid absorption of the unmodified antimony oxide powder to DOP is more serious, and three modified oxygen
The catalytic effect for changing two antimony is decreased obviously, and illustrates antimony oxide powder in actual applications to the invalid absorption of DOP plasticizer
Amount is reduced, and avoids the decomposition of polymer in the process for thus resulting in.This is because modified antimony oxide is inorganic
Powder reuniting is reduced, and intergranular space reduces, and decentralization is higher.Substantially ratio changes the activation index of modified antimony oxide
Property before antimony oxide activation index it is big.Because unmodified antimony oxide inorganic particle relative density is larger, and
And surface be in polarization state, the easy free settling in water, and the antimony oxide inorganic powder surface of modified process by
Polarity is changed into nonpolar, presents stronger hydrophobicity, this hydrophobic fine particle, due to huge table in water
Face tension force so as to float just as oil film and do not sink, therefore modified powder activation index increases.
Based on above-mentioned, it is an advantage of the current invention that the present invention using stibnite as raw material, by calcined oxide product
Sb2O3, carrying out purification and remove arsenic and iron, further melting purification reoxidizes to obtain pure Sb2O3And be modified, take out therein heavy
Metal ingredient, and can also be acidified using acid ion therein, to increase operation rate, environment-friendly type more preferably, and is changed
Property, activation index and output capacity be greatly improved, with environmental protection, activity index be high, output capacity is high and low stain etc.
Characteristic, the production efficiency is greatly improved, and function admirable, convenient production process operation, cost is relatively low.
Presently preferred embodiments of the present invention is the foregoing is only, not to limit the present invention, all essences in the present invention
Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.
