Description
Technical field
The present invention relates to waste tyre rubber powder room temperature technical field of desulfurization, especially a kind of waste-tyre rubber-powder room temperature desulfurization side
Method.
Background technology
In the prior art, it is to obtain it with desulfurizing agent effect in high temperature environments to prepare rubber powder for waste tire
, this not only causes the inferior quality of the rubber powder prepared, but also the rubber powder yield for also resulting in preparation is relatively low；It is most important also
Cause rubber powder desulfurization energy consumption higher.
Based on this, there is substantial amounts of Research Literature in the prior art, waste tire is subjected to desulfurization process at low ambient temperatures
Afterwards, then it is prepared into rubber powder or low-temp desulfurization processing, such as Patent No. is carried out to it during rubber powder is prepared
200510033281.1 using desulfurizing agent, desulfurization process prepares odorless reclaimed rubber at low ambient temperatures to waste tire；For another example patent
Number waste tire desulfurization process is carried out using atmospheric low-temperature ageing effect desulfurizing method for 200710056185.8.
It is handled although in the prior art atmospheric low-temperature desulfurization or low-temp desulfurization can be carried out to waste tire, at it
The method of science and engineering skill cannot still meet waste tire desulfurization and prepare the requirement of rubber powder product, and then cause waste tire recycling profit
It is subject to limitation in the application of chemical field with the product for preparing rubber powder, the added value in turn resulting in rubber powder is relatively low；This is main former
Because being that the desulfurization effect that waste tire recycling is prepared during rubber powder is poor.
Based on this, this researcher combines long-term exploration and constantly attempts, and waste tire is cut, is magnetic separation, micro-
It is ground after wave radiation processing, reduces the difficulty being ground to waste tire, improve the brittleness of waste tire, reduce and grind
Grind energy consumption；It impregnated in conjunction with the ammonium hydroxide after magnetic separation, add in desulfurizing agent, ultrasonication, ammonium hydroxide after grinding, magnetic separation after microwave radiation
Impregnate, microwave radiation and etc. restriction and technological parameter restriction so that S -- S, the bond energy of S-C keys in waste tire
It is changed, the bond energy of C-C keys is protected, and the low-temp desulfurization field during rubber powder is prepared for waste tire recycling and is carried
A kind of new approaches are supplied.
The content of the invention
In order to solve the above technical problems existing in the prior art, the present invention provides a kind of waste-tyre rubber-powder room temperature and takes off
Sulphur method.
It is realized particular by following technical scheme：
A kind of waste-tyre rubber-powder room temperature sulfur method, after waste tire to be cut into the particle of 10-20 mesh, is sent to
Magnetic separation in magnetic separator, then using microwave radiation processing 20-30min after, then be sent to the powder that 40-60 mesh is ground into grinder
It is last, then be sent to magnetic separation in magnetic separator and handle, then place it in ammonium hydroxide, it is impregnated after being mixed according to mass ratio for 1: 2~3
After handling 1-3h, then by powder filter, obtained filter residue, and will after filter residue uses microwave radiation processing 5-10min, then by its
It is placed in grinder and is ground into 70-90 mesh powders, then be sent to magnetic separation in magnetic separator and handle, then it is de- using adding in thereto
Sulphur agent, and use ultrasonication 10-20s, obtains mixed-powder, then by mixed-powder and ammonium hydroxide according to mass ratio is 1: 1.1
10-20min is impregnated after~1.5, then after being filtered, obtains filtered fluid and filter cake, filter cake is used into microwave radiation processing 1-4h
Afterwards, rubber powder is obtained；Filtered fluid, which returns, impregnates 40-60 mesh powders.
The microwave radiation, frequency 2450Hz.
The ammonium hydroxide, concentration 30-70%.
The ultrasonic wave, frequency 300-3000Hz.
The desulfurizing agent, material composition is in parts by weight 1-3 parts of tall oil, 0.1-0.7 parts of rosin, calcium bicarbonate
0.01-0.09 parts, 1-2 parts of quick lime, 0.7-1.3 parts of calcium oxalate, 3-7 parts of allicin.
The desulfurizing agent, material composition is in parts by weight 2 parts of tall oil, 0.5 part of rosin, calcium bicarbonate 0.05
Part, 1.5 parts of quick lime, 0.8 part of calcium oxalate, 5 parts of allicin.
The desulfurizing agent, its preparation method are after mixing calcium bicarbonate, quick lime, to use temperature as 100-200 DEG C
Baking processing 1-2min, then the water for accounting for quick lime weight 3-7% is spilt to its surface, and be then added thereto calcium oxalate, then will
It, which is placed in grinder, is ground into 80-100 mesh powders, then adds in tall oil, rosin and allicin thereto, using ultrasonic wave
Frequency handles 10-20s for 2450Hz, you can.
Compared with prior art, technique effect of the invention is embodied in：
After waste tire is cut into particle, microwave radiation three times and three times magnetic separation processing are being carried out, in conjunction with one
Secondary Catalyzed by Ultrasonic Wave processing and the addition of desulfurizing agent so that waste tire can carry out desulfurization at normal temperatures, reduce to useless
Old tire recycles desulphurization cost and desulfurization energy consumption；In conjunction with the introducing of ammonium hydroxide immersion treatment technology so that in waste tire
S -- S, S-C keys bond energy carry out microwave radiation processing, Catalyzed by Ultrasonic Wave processing and desulfurizing agent add in mixed processing
Under, by serious destruction, and while above-mentioned bond energy is destroyed, the bond energy of C-C keys is protected, reduced in desulfurization work
To the destruction of C-C keys in sequence, the yield and quality of rubber powder is improved.
The present invention magnetic separation and is ground twice especially by microwave radiation three times and three times so that the rubber powder of preparation
Quality is more excellent, and combines the grinding after microwave radiation so that grinding difficulty reduces, and handles, makes in conjunction with a Catalyzed by Ultrasonic Wave
Obtaining desulfurizing agent can act on the sulphur ingredient in waste tire at low temperature, and then reduce the purpose of sulphur ingredient so that glue
The raising that the quality of powder obtains, and reduce the desulphurization cost during being recycled to waste tire.
