The present invention can be used not only to treat a wide range of contaminated groundwater and river water but also to treat VOCs, BTEX and the like present in the air by constituting a refractory composite organic compound material by using a composite of an organic support (ACRYLONITRILE BUTADIENE STYRENE) And a photocatalytic composite capable of removing the same volatile organic compound.
The ABS is a generic name of a kind of impact resistant thermoplastic resin composed of three components of acrylonitrile, butadene and styrene. It is a general industrial resin imparting advantages (gloss, formability, rigidity, chemical resistance, impact resistance, etc.) .
Therefore, it is needless to say that the ABS can be modified or applied according to the use purpose by adjusting the composition ratio or changing the additives.
The present invention relates to a photocatalyst-attaching step (S100) for attaching a photocatalyst to an ABS organic-based support; A step (S200) of pretreating ABS organic support for heating the ABS organic support with a photocatalyst to a predetermined temperature in the crucible so that the photocatalyst can be adsorbed on the ABS organic support; A cooling step (S300) for cooling the pretreated ABS organic support under specific conditions so as to have characteristics for each use condition; (S500) for removing and fixing the remaining portion of the photocatalyst adhering to the cooled ABS organic support (S400), and drying the post-treated photocatalyst-ABS organic complex to a predetermined temperature to complete the composite composition (S500) .
Each step will be described in detail below.
The photocatalyst-attaching step (S100) is for temporarily adhering the photocatalyst powder to the ABS organic support, and the photocatalyst powder and the ABS organic support are contained in the tray and are attached to each other by stirring action.
More specifically, when ABS is applied to a train coated with a photocatalyst and stirring is carried out at a speed of 10 RPM for 5 minutes, the photocatalyst is temporarily adhered to the ABS organic support due to entanglement of the photocatalyst powder. Here, the photocatalyst material may be composed of ZnO, TiO 2, or the like.
In the photocatalyst-attaching step (S100), a pretreatment step (S200) of the ABS organic support is performed in which the ABS organic support is heated to a predetermined temperature while the photocatalyst powder is temporarily attached to the surface of the ABS organic support.
The pretreatment step (S200) of the ABS organic support is a step of placing a photocatalyst-containing ABS organic support on a heating furnace such as an electric furnace or a tundish, heating the substrate at 300 ° C for 3 minutes, It is a step to make a condition that the photocatalyst material can be adhered by making the surface of the ABS organic support slip off but not melt.
When the pretreatment step for attaching the photocatalyst material is completed as described above, a cooling step (S300) for cooling the ABS organic support having the photocatalyst on the electric furnace or the crucible is performed.
The cooling step (S300) may vary the characteristics of the ABS organic support depending on the conditions under which the organic support having the photocatalyst attached thereto is cooled.
The first cooling step may be performed in a delayed cooling step (S300-1) in which the ABS organic support is slowly cooled in a heated crucible to immobilize the photocatalyst material. In the delay cooling step (S300-1), the ABS component on the surface of the ABS organic support is slowly hardened, which is advantageous in that sufficient surface strength can be maintained.
The second cooling step may be performed in a room temperature cooling step (S300-2) in which the ABS organic support is quickly removed from the heated crucible and cooled at room temperature to immobilize the photocatalyst material. In the room temperature cooling step (S300-2), there is an advantage that a relatively high impact strength can be maintained under the condition of cooling at room temperature.
The third cooling step may be performed in a rapid cooling step (S300-3) of immobilizing the photocatalyst material by taking out the ABS organic support in a heated crucible and rapidly cooling it in a freeze dryer. In the rapid cooling step (S-300), since the ABS of the high temperature state is instantaneously cooled, the photocatalyst material is instantaneously immobilized, so that it is advantageous that the fine surface area can be utilized as widely as possible.
The ABS organic support cooled by any one of the above three methods is subjected to a post-treatment step (S400) for desorbing the photocatalyst powder imperfectly attached to the surface.
The post-treatment step (S400) may be performed by ultrasonic cleaning at 700 W for 30 minutes to remove the photocatalyst powder from the ABS organic support.
In the post-treatment step (S400), the post-treated ABS organic support is dried at 100 DEG C for one hour to evaporate moisture to perform the composite completion step (S500). The final ABS organic support composite can be completed by the complex preparation step (S500).
An embodiment of the production of the photocatalyst-organic composite composition for treating a refractory organic compound material using ABS according to the present invention will be described with reference to FIG.
FIG. 2 is a photograph of a process of prototyping a photocatalyst-organic composite composition for treating a refractory organic compound material using ABS according to the present invention.
<Examples>
ABS (ACRYLONITRILE BUTADIENE STYRENE) Prepare organic support specimens.
Then, the photocatalyst material powder mixed with ZnO and laponite in a ratio of 10: 1 is put into a container, and the prepared ABS organic support is dropped and mixed at 10 rpm for 5 minutes.
The specimen with the mixture of the photocatalyst material powder and the ABS organic support is placed in a crucible containing the photocatalyst material powder and sintered at 300 ° C for 3 minutes.
After cooling the ABS organic support with photocatalyst material sintered at a certain temperature under specific conditions, ultrasonic cleaning is performed at 700 W for 30 minutes. Then, the cleaned ABS organic support is washed with distilled water and dried to complete the final ABS organic support composite.
The photocatalyst-organic composite composition for treating a refractory organic compound material using ABS according to the present invention has the following advantages: the photocatalytic composite is immobilized on the ABS surface, and the surface area is increased due to surface contraction, And the produced ABS photocatalyst has a better photocatalytic efficiency than that existing in the water layer because it floats in water.
As a result of producing the ABS photocatalytic organic composite composition through the technique of the present invention, it is possible to identify the amount of the photocatalyst located on the ABS surface by confirming the photocatalyst material (Zn, Ti) which does not exist in the ABS, It can be seen that the surface area is increased due to surface contraction.
In addition, there is a possibility that the ABS size can be applied to the air pollution prevention field by processing the filter material which can be used in the air pollution prevention facility such as the absorption tower by scale-up.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the present invention as defined by the following claims It can be understood that

S200: ABS organic support pretreatment step
