As a technical means for achieving the above object, the present invention is 7 to 20% charcoal, 80 to 90% polyurethane, 3 to 15 weight of carbon composed of 72 to 79% carbonaceous material and 21 to 28% minerals % Mixture of plasticizers DOP, DOA, DDP, DHP, DBP, TCP, DEP, DMP, TPP, PPG and mixed 2: 1 or 3: 1 into the mixing chamber and put into 20-30 ℃ After stirring for 50 minutes, foam is formed at 120 to 170 ° C. to form a foam through the head of the foamer, and the foam formed through the head is transferred to a cutter through a conveyor belt and cut into a predetermined block. The foam cut by the cutter is aged at 20-30 ° C. in a aging room for a certain time, cut in a cutting room, and then shipped.

Charcoal has a specific surface area of 100㎡ / g∼500㎡ / g and selects one of oak, palm shell and charcoal with particle diameter of 1-5㎛ to mix with urethane to maintain the unique physical and chemical properties of charcoal. Of course, it can exert more deodorant, adsorption, and antibacterial properties.

Charcoal varies from material to material, but typically has an inner surface area of 300 cubic meters free per gram. In other words, the palm-sized charcoal has an inner surface about the size of a tennis court.

Among the charcoal, activated carbon maximizes the internal surface area and has an amazing group of holes of 3,500 square meters, and charcoal is called activated charcoal because it is a living space for microorganisms to adsorb bacteria and odors. Therefore, the smaller the number of holes, the better the charcoal.

In addition, the porosity of charcoal has the ability to control moisture and antiseptic action.

In addition, the negative ions generated from the charcoal itself act as a lack of oxygen to clear the air and help all life activities. For example, the severe odor of the refrigerator when the oxygen in the refrigerator lacks a lot of oxygen-like microorganisms multiply and give off gas.

In this environment, a lot of positive ions are naturally present and the anions are very small. At this time, if you put the charcoal can change the environment by 180 degrees due to the effect of microorganisms parasitic charcoal and anion emitted by the charcoal, and thus no smell.

In this way, charcoal neutralizes bad cations in our body, so using charcoal rather than machine-made anions, we can simply supply anions.

Charcoal is 80% carbon and the rest is composed of minerals (calcium (Ca), sodium (Na), iron (Fe), magnesium (Mg), potassium (K), phosphorus (P), etc.) The same charcoal is balanced by the natural minerals that the tree sucks up from the soil, concentrating on the charcoal process.

Deodorizing effect can not be expected when mixing less than 7% by weight of charcoal, and when mixing more than 20% by weight, various effects such as antimicrobial can be obtained. There is a problem of crumbs.

In addition, silver (Ag) of nanometer (nm, 1 billionth of a meter) size is added to shield the antimicrobial effect and electromagnetic waves. When 3% or less of silver (Ag) is added, the characteristics of the function of the electromagnetic shielding are lost, and when 15% or more is added, the electromagnetic shielding function is excellent but the physical properties of the mixture are deteriorated.

When polyurethane is used, urethane is difficult to mold when 80% by weight or less of polyurethane is mixed, and when it is mixed by 90% by weight or more, moldability is good, but the effect of antibacterial and deodorization is lowered.

Plasticizers are formulated into resins to reduce the intermolecular cohesion of polymer molecules, thereby providing proper elasticity and flexibility to reduce melt viscosity, thereby improving the processability of resins. Select one of DHP (Dihexyl phthalate), DBP (Dibutyl phthalate), TCP (Tricresylphosphate), DEP (Diethyl phthalate), DMP (Dimethyl phthalate) and TPP (Triphenyl phosphate) In order to improve processability and flexibility, a 2: 1 mixture is used, but a mixture is preferably 3: 1.

When the stirring temperature in the mixing chamber is 20 ° C. or lower, the viscosity is high, and the raw material itself is hardened, so that molding is difficult at the time of molding.

If the foaming temperature in the foaming machine is less than 120 ℃ foaming melting point is low, if the foaming melting point is higher than 170 ℃ high foaming is difficult to form a difficult form.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic configuration diagram of an apparatus for manufacturing a cushioning material having an excellent active function according to the present invention, by mixing the injection raw material at a predetermined temperature under the main raw material tank 10 and the solvent tank 20 into which the main raw material and the solvent are respectively injected; The mixing chamber 30 is spoken for foaming, the conveyor belt 50 is rolled over to convey the foam 40 foamed in the mixing chamber 30, and the foam 40 is moved to a predetermined block. The cutting machine 60 is installed at one side of the conveyor belt 50 so as to be cut by the block, and the maturing chamber 70 is installed to ripen the foam 40 cut by the cutting machine for a predetermined time.

Referring to the cushioning material manufacturing method excellent in the active function of the present invention having such a configuration as follows.

Figure 2 is a schematic process diagram for producing a cushioning material excellent in the active function according to the present invention, the cushioning material excellent in the activation function of the present invention is charcoal consisting of 72 to 93% by weight carbon, 18 to 20% by weight mineral, and diluent Phosphorous polypropylene glycol (ppg) is pre-stirred at a ratio of 1: 3 or 1: 2 in the case of low viscosity, and then is introduced into the main raw material tank 10 and the solvent tank 20, and the injected raw material is about After the stirring process for about 1 hour is injected into the mixing chamber 30 through a pump and a nozzle.

The raw material injected into the mixing chamber 30 is formed into a foam after performing a foaming process by mixing the raw materials, and is cut through the conveyor belt 50 that is rolled down to the lower side of the mixing chamber. The cutting machine is transferred to the cutting machine to cut into blocks of a predetermined size.

The foam cut into a predetermined size and formed into blocks is transferred to a aging chamber through a transfer conveyor, and cut to a predetermined size through a cutting machine through a aging process at about 20 to 30 ° C. for about 24 hours or more to manufacture a cushioning material.

If the aging temperature is 20 ℃ or less, the bubble formed in the foaming process is not removed and is contracted, there is a problem that the gas remaining in the bubble is not discharged above 30 ℃.

As described above, the present invention is produced in a block through the foaming process and aged for 1 to 2 days to set the pillow shape to make a finished product in three-dimensional cutting, which can maintain the far-infrared emission effect, antibacterial and deodorant function for a long time. Excellent effect.
