Generally, toner is manufactured to a desired particle size through a process of dispersing, heating and melting, cooling solidification, coarsely pulverizing, pulverizing and classifying raw materials such as a binder resin, a charge control agent, a colorant, and a release agent, to be used in a copying machine.

In the toner manufacturing process, a binder made of polyester resin is pulverized and used as a raw material of the toner. In the step of crushing the binder, a binder powder having a wide range of particle sizes is formed, and among the binder powders having a wide range of particle sizes, a binder powder corresponding to a particle size of a reference range is classified and used as a raw material of the toner. By the way, the binder powder finely ground than the particle size of the reference range can be pulverized and reused as a raw material of the toner, but the binder powder finely pulverized than the particle size of the reference range, that is, 180 mesh or more, is used to manufacture the toner. Since the process is not uniformly mixed with the pigment and the like, the situation is discarded as it is, there is a problem that environmental pollution occurs accordingly.

For example, Korean Patent No. 0375458 discloses a method of preparing a powder by dissolving a binder resin and a curing agent in a diluting solvent, adding an additive, and dispersing it through a predetermined step, followed by air spinning. However, the powder produced by such a method has a problem that the particle size is very wide and practical application is difficult.

In addition, Korean Patent No. 0161100 discloses a method of recovering a polyester resin, a polyurethane resin, PVC and the like and reforming the resin. However, there is a problem that the physical properties of the resin reformed in this way is poor.

In addition, Korean Patent Laid-Open Publication No. 2005-52073 discloses a finishing coating composition composed of a room temperature-curable organic liquid resin, glass beads, and a silica-based compound. However, such a coating composition for finishing is expensive and difficult to apply indoors.

In order to achieve the above object of the present invention, the building finishing gel composition using the waste powder of the solid toner according to an embodiment of the present invention is a step of grinding the binder waste powder for the toner into a powder of 300 to 350 mesh Pulverizing the mica to a powder of 300 to 350 mesh, 35 to 45 parts by weight of the binder powder for toner, 35 to 45 parts by weight of mica, 5 to 10 parts by weight of zeolite powder and 5 to 10 parts by weight of potassium hydroxide powder Mixing uniformly to form a powder mixture, mixing 100 parts by weight of the powder mixture with 140 to 160 parts by weight of water, stirring for 4 to 5 hours, gelling, and sealing packaging the gelled mixture. .

In addition, the step of gelling the powder mixture is carried out at 60 to 80 ℃. In addition, the gelled mixture is sealed packaged immediately after the gelling reaction is completed to prevent the gelled mixture from curing in contact with air. In addition, 0.4 to 0.6 parts by weight of at least one powder selected from the group consisting of tourmaline powder, precious stones powder and elvan powder in the step of mixing the toner binder waste powder, mica powder, zeolite powder and potassium hydroxide powder It may include. In addition, it is preferable that the average particle size of the tourmaline powder, precious stone powder and elvan stone powder is 300 to 350 mesh, respectively.

It can be, and has the effect of obtaining a high value-added building finishing composition.

In addition, with reference to the drawings will be described in detail step by step the manufacturing method of the gel composition for building finishing using the waste powder of the solid for toner according to an embodiment of the present invention.

Figure 1 shows the procedure of the manufacturing method of the gel composition for building finishing using the waste powder of the solid for toner according to an embodiment of the present invention.

First, a binder waste powder for toner of 300 to 350 mesh, which is the main raw material of the present invention, is formed (step S10).

Specifically, in the process of forming a toner binder powder composed of saturated polyester resin as a main component, a binder waste powder for toner finely pulverized to 180 mesh or more is obtained, and the binder waste powder for toner of 180 mesh or more obtained is obtained. To grind again to prepare a binder powder for toner of 300 to 350 mesh.

When the average particle size of the toner binder waste powder included in the building finishing composition using the waste powder of the toner solid is less than 300 mesh, the physical properties of the building finishing gel composition kneaded with water decrease, and the binder waste for the toner If the average particle size of the powder exceeds 350 mesh, the physical properties of the building finishing gel composition no longer increase with respect to the cost of grinding the waste powder for the toner binder.

Cicadas are pulverized to form mica powder of 300 to 350 mesh (step S20).

In the present invention, the biotite, which is used as the main raw material of the gel composition for building finishing together with the binder powder for toner, is a substance that emits 90% or more of far-infrared rays that promotes blood circulation and activates cellular activity of the human body.

The waste toner binder powder, mica powder, zeolite powder and potassium hydroxide powder are mixed to form a building finishing composition using the waste powder of the toner solid body (step S30).

Specifically, 35 to 45 parts by weight of the binder powder for toner of 300 to 350 mesh, 35 to 45 parts by weight of mica powder, 5 to 10 parts by weight of zeolite powder and 5 to 10 parts by weight of potassium hydroxide powder are mixed uniformly. To form.

When the content of the binder waste powder for the toner contained in the powder mixture is less than 35 parts by weight, the bonding strength of the gel composition for finishing the building decreases, and when the content of the binder waste powder for the toner exceeds 45 parts by weight, the content of the mica powder decreases. The release function of far infrared rays and anions of the finishing composition is lowered.

In addition, if the content of the mica powder contained in the powder mixture is less than 35 parts by weight, the function of releasing the far infrared rays and anions of the gel composition for building finishing is reduced, and when the content of the binder waste powder for the toner exceeds 45 parts by weight, the binder waste for the toner The content of the powder is lowered, thereby lowering the bonding strength of the gel composition for building finishing.

In the present invention, the powder mixture is also formed by including the zeolite powder.

It is used as an adsorbent by using this property, and is used as a molecular sieve for separating particulates of different sizes. Specifically, it is widely used as a purifier and a filter device, a detergent deodorant, a CPU coolant, and a catalyst in the petrochemical industry .

If the content of the zeolite powder contained in the powder mixture is less than 5 parts by weight, the adsorption power of the gel composition for building finishing is lowered, and if the content of the zeolite powder is more than 10 parts by weight, the building composition gel finish for the building is porous and Is lowered.

In addition, in the present invention, potassium hydroxide is used to promote the dissolution of the above-mentioned mixture of the waste powder for toner, mica, zeolite and gelation in water.

When the content of the potassium hydroxide powder in the building finishing composition using the waste powder of the toner solid is less than 5 parts by weight, the mixture of the waste powder of the toner binder, biotite and zeolite does not gel properly, and the content of potassium hydroxide powder When it exceeds 10 parts by weight, the strength of the gel composition for building finishing finished on the building is greatly reduced.

The powder mixture is prepared by uniformly mixing the toner binder powder, mica powder, zeolite powder, and potassium hydroxide powder by the content ratio as described above.

In addition, the waste powder of the toner solid powder may be mixed with a binder powder for toner, mica powder, zeolite powder, and potassium hydroxide powder, optionally with one or more powders selected from the group consisting of tourmaline powder, gemstone powder, and elvan powder. The composition used for building finishing can be constructed.
