Hereinafter, preferred embodiments of the present invention and physical properties of the respective components will be described in detail with reference to the accompanying drawings. However, the present invention is not limited thereto, And this does not mean that the technical idea and scope of the present invention are limited.

The functional pillow in which anions are released according to the present invention is composed of polypropylene glycol (PPG), methylene diphenyl diisocyanate (MDI), yellow pozzolan and rare earths, and contains 100 parts by weight of polypropylene glycol, 35 to 45 parts by weight of diphenyl diisocyanate, 50 to 60 parts by weight of yellow pozzolan and 20 to 30 parts by weight of rare earth.

The polypropylene glycol reacts with the methylene diphenyl diisocyanate to form the polyurethane which is the main material of the functional pillow in which the anion is released according to the present invention.

Generally, the polyurethane is accompanied by various side reactions as follows because the reaction between the hydroxyl group and the isocyanate group of the polyol is very strong in the main reaction or the isocyanate reaction. Particularly, the reaction with water during the side reaction generates carbon gas to be used in the production of the foam, and the generation of the trimer of the diisocyanate increases the heat resistance as an additional crosslinked structure. Therefore, the polyisocyanurate foam Reaction.

The methylene diphenyl diisocyanate is contained in an amount of 35 to 45 parts by weight, and reacts with the hydroxyl group of the polypropylene glycol to produce a polyurethane. The methylene diphenyl diisocyanate used in the present invention is a polyurethane It reacts vigorously with the moisture in the air during the process, so that the residual isocyanate exhibits excellent reactivity, which is largely replaced by urethane groups in the product.

If the content of the methylene diphenyl diisocyanate is less than 35 parts by weight, the polyurethane production reaction may not proceed properly because the content of the methylene diphenyl diisocyanate is too low compared to the polypropylene glycol. If the methylene diphenyl diisocyanate content exceeds 45 parts by weight, Methylene diphenyl diisocyanate is not preferable since the byproduct remains.

The loess pozzolan contains 50 to 60 parts by weight of the loess pozzolana and serves to provide a functional pillow exhibiting far-infrared radiation, anion release, antibacterial effect and humidity control effect.

The Hwangto pozzolan powder is used as a powder having a particle size of 80 to 200 meshes by collecting and pulverizing natural loess pozzolan mineral which is widely produced on the west coast of the Korean peninsula. 61 to 64 percent of silicon oxide, 12 to 18 percent of aluminum oxide, 0.5 to 0.7 percent of titanium oxide, 3.2 to 3.8 percent of potassium, 1 to 3 percent of sodium oxide, 4 to 5.5 percent of iron oxide, 0.01 to 0.07 percent of manganese oxide, To 2%, oxidized phosphorus 0.04 to 0.3%, germanium 0.000002%, and the like.

The yellow phosphor pozzolana powder emits a large amount of far infrared ray which is beneficial for human health to about 94 to 97%. The far infrared ray of the above wavelength is effective for restoring fatigue, promoting circulation of blood, activating circulation machinery, expanding capillary blood vessels and removing bad smell.

In addition, the above-mentioned loess pozzolan powder releases an average of 972 psi / cc, which releases a very large amount of anions among natural minerals, and provides a pillow that exhibits effects of decomposing harmful substances, supplying oxygen, sterilizing and deodorizing And the like.

In addition, the above-mentioned loess pozzolana powder is porous and has many pores. It has 99.9% sterilizing effect of bacteria and bacteria in the air in contact with air, and exhibits effects such as deodorizing effect, fungus dying, mite avoidance and aphid avoidance.

In addition, the above-mentioned loess pozzolan powder has a moisture-absorbing effect that maintains the optimum humidity by absorbing or discharging water according to the humidity in the air. This is an effect for the loess but the loess pozzolan powder is porous and has numerous pores. It is superior in the better dryness effect.

When the content of the yellow clay pozzolan powder is less than 50 parts by weight, the above-mentioned effect is insignificant. When the content of the yellow clay pozzolan powder exceeds 60 parts by weight, the effect is not greatly improved and the effect of the polyurethane reaction is decreased. The loess pozzolan component may not be solidly present in the polyurethane reactant and may be desorbed.

The rare earth powder is contained in an amount of 20 to 30 parts by weight, and serves to provide a functional pillow in which the amount of emitted negative ions is further improved.

The rare earth metals are collectively referred to as 17 elements combined with scandium and yttrium, which are 3A groups of the periodic table and lanthanides of atomic number 57 to 71, and 14 elements below cerium excluding lanthanum, are collectively referred to as lanthanides. Elements from the lanthanum to the samarium element are called the yttrium element, and the 11 elements including the element of the cerium group, the element from europium to luteium, yttrium, and scandium are referred to as yttrium elements. All of these elements belong to the rare element, and promethium is a radioactive element (radioactive element), and stable isotope (isotope) does not exist. An atomic number is an odd number that is less than an even number, and is generally silver white or gray metal. In addition, it slowly oxidizes in the air. It is soluble in acids and hot water but does not dissolve in alkali. Its chemical properties are very similar, and it usually produces compounds of +3 in total. +4 in cerium, terbium and praseodymium, and in ytterbium, +2 is also available. The alkali and alkaline earth metals are followed by positive (positive), and the hydroxide is the base.

At this time, it is preferable that the rare earth powder used in the present invention is made of lanthanum or cesium having an excellent anion release performance. If the content of the rare earth powder is less than 20 parts by weight, the effect is insignificant. If the content of the rare earth powder is less than 30 parts by weight The effect is not greatly improved but the manufacturing cost is increased.
