Description

Functional paint {Functional paint}

The present invention relates to functional paints, and more particularly to paints that are flame retardant as well as anion generation.

Negative ions are negative ions in the air. When pure air is in a stable state, the ratio of anions and cations is about 1: 1.2. However, with the development of human civilization, the industrial development is getting farther away from the natural environment. The transition to the society of advanced industrialization is a condition where the ionic composition ratio of the steady state is destroyed by synthetic polymers, cement, electromagnetic waves, environmental pollution, etc., and the cations are predominant. As a result, it becomes a large particle mass having no activity. At this time, the number of ions in the large particle mass is remarkably reduced and worsens headache, tension, and the like.

Normally, city dwellers drink about 200 anions / cc (max.) Of negative ions, which is decreasing. Drinking 1000 pcs / cc of negative ions increases the activity of α waves in the brain and inhibits serotonin and free histamine. Negative ions promote the functioning of the whole body by keeping the three principles of health maintenance, such as blood purification, cell activation, and nerve regulation in harmony. If you stay in forests, valleys or waterfalls with a lot of negative ions for a long time, you can feel refreshed, refreshed, and feel better. Anions are therefore called "vitamins in the air."

Anion functions include deodorization, antibacterial, dehumidification, water softening (water), air cleaning, and the like. In order to create an anion atmosphere, materials and paints that emit anions are being developed.

Representative materials for generating anions are known materials containing tourmaline and radioactive elements. The tourmaline is spontaneously polarized and, in the presence of water, causes a discharge to electrolyze the water and generate anions in the process. Radioactive elements decay and emit radiation such as α, β, and γ rays, which are the nucleus of helium, β rays are electron beams, and γ rays are electromagnetic waves with very short wavelengths. It is known that anion is released from a substance containing radioactive elements by ionizing a gas or a solid. It is also reported that more negative ions are generated when a tourmaline that is spontaneously polarized and a material containing radioactive elements are mixed.

Therefore, a number of anion generating materials and applications to which such tourmaline powder or radioactive element-containing materials are added have been filed. Japanese Laid-Open Patent Publication No. 2002-145611 discloses a mineral mixed powder obtained by mixing a tourmaline powder and a powder of a mineral having a radioactive substance emitting weak radiation. Here, as a kind of ore having radioactivity, barite, pyranurite, phosphate minerals of cerium group metals, brown salts and hexondol are presented. Japanese Laid-Open Patent Publication No. 2001-131529 discloses an ion generator in which a rare earth element and a spontaneous polarization polar material are mixed, and garnet is used as the spontaneous polarization polar material. Japanese Laid-Open Patent Publication No. 2001-19420 discloses a powder in which a powder having spontaneous polarization and a powder of an excitation agent for generating anions are mixed. The patent (Japanese Laid-Open Patent Publication No. 2001-19420) presented a tourmaline as a spontaneous polarized powder, and suggested that a ferroelectric can also be used. In addition, as an exciton generating anion, natural ores that emit radiation are proposed. Korean Patent Laid-Open No. 2001-038856 discloses an antifouling paint additive in which a monazite powder and a tourmaline powder are mixed. Korean Unexamined Patent Publication No. 2003-018026 discloses a paint using a natural mineral containing a radioactive element. Here, as a natural mineral, a rough rock mineral of hornblende, olivine, and mica having a radioactive concentration of 370 Bq / g or less was used.

On the other hand, first ammonium phosphate is a flame retardant widely used as a filler for fire extinguishers, and is used as a flame retardant for imparting flame retardancy to various products. Korean Unexamined Patent Publication No. 2001-49099 discloses a composition of a fire retardant containing ammonium phosphate and its manufacturing method. Korean Unexamined Patent Publication No. 2002-69391 discloses a nonflammable and fire resistant transparent paint containing ammonium phosphate and its manufacture. The method is public.

As described above, anion generating paints and flame retardant paints have been disclosed, but there are no paints having both anion generating and flame retardant functions.

The inventors of the present invention are mostly a tourmaline material used as a negative ion generating material, while trying to solve the inconvenience of adding a new flame retardant in order to add flame retardancy, while trying various ways, the first ammonium phosphate used as a flame retardant spontaneously The present invention has been completed by noting that it is a polarizing ferroelectric. An object of the present invention is to provide a paint which generates anion and is imparted with flame retardancy.

Now, the principle of generating anions in the anion generating paint containing ammonium monophosphate according to the present invention will be described.

The positive and negative charges that appear when the crystal plate temperature is changed are also called pyro electricity. This property of crystals is also called superelectricity. Crystals are microscopically composed of several kinds of fine particles with positive and negative charges. Since the crystal is electrically neutral as a whole, unless externally charged, the total amount of positive and negative charges in the crystal is the same. However, the center of gravity of positive and negative charges may not coincide with the case of coincidence depending on the symmetry of the crystal. Inconsistent crystals are called polar crystals, which have electrical polarization in their natural state and are called spontaneous polarization in a broad sense. Since spontaneous polarization is generally temperature dependent, spontaneous polarization changes when the temperature of the polar crystal plate is changed, and positive and negative charges corresponding to the change appear on both sides of the plate. Such polar crystals all exhibit pyroelectricity. Representative pyroelectric materials include tourmaline. The tourmaline polarizes the tourmaline crystals into the + and-poles when heated, and discharges the moisture instantaneously when the tourmaline is in contact with moisture. At this time, water is electrolyzed and water molecules (H ₂ O) are separated into hydrogen ions (H ⁺ ) and hydroxyl ions (OH ⁻ ). The separated hydrogen ions (H ⁺ ) are attracted to the negative electrode and are combined with the electrons emitted therefrom to neutralize and become hydrogen gas (H ₂ ) to evaporate. That is, water becomes alkali ionization. Further hydroxyl ions (OH _-), in combination with the surrounding water molecules are surface-active substances, known as hydroxyl (H ₃ O ₂₎ anions. The anion is released by such a process. Since the ammonium monophosphate used in the present invention has a superelectricity like tourmaline, it releases anion like tourmaline and can be used as a tourmaline substitute. However, since most of the pyroelectric material alone does not generate anion or is extremely weak even if it is generated, it is not easy to use it as an anion generating material alone.

On the other hand, the radioactive element contained in the material containing the radioactive element used in the present invention is decomposed to emit radiation such as α-ray, β-rays, γ-rays, α-rays are helium nucleus, β-rays are electron particles Lines and gamma rays are electromagnetic waves with very short wavelengths, and both act to ionize gases and solids. The emission of radiation from radioactive elements is independent of the chemical form or physical state of the radioactive element. The anion generating material according to the present invention only needs to contain the radioactive element presented in the present invention, and the amount of anion generation is related to the total content of the radioactive element. For example, in the case of radioactive element K-40, the abundance ratio of isotope is 0.0118%. Therefore, when using mineral containing potassium (K), it is preferable to use mineral containing 5% or more of mineral, preferably 10%. Do. If the potassium content is low, the amount of radiation emitted is too small, the effect of generating negative ions is lowered.

Except for the concentration of radioactive elements that form a decay series, such as uranium, most of the radioactive element-containing minerals contain trace amounts of radioactive elements that form a decay series or emit weak radioactivity that is harmless to the human body. Although it is believed that, it is preferable to use a substance containing a radioactive element that emits radiation below the allowable radiation dose. For this reason, all substances containing radioactive elements can be used in the anion generating material of the present invention, and the amount of anions can be controlled by using radioactive element-containing substances having different kinds or contents of radioactive elements. However, radioactive elements alone do not have enough anions or are not reasonable in terms of price.

As mentioned in the prior art, the generation of negative ions from an anionic material is caused by the spontaneous polarization of the radiation emitted from the radioactive material containing radioactive elements such as tourmaline and radioactive element-containing materials. By promoting the ionization of the ion, it is easy to release the anion, thus increasing the amount of anion released.

Since the ammonium monophosphate used in the present invention is superelectric, when mixed with a radioactive element-containing material, anions are generated and at the same time, it is possible to impart flame retardancy. The amount of the ammonium monophosphate added is not limited but is preferably within 5% by weight to 50% by weight with respect to 100% by weight of the paint. If it is less than 5% by weight, it is difficult to secure flame retardancy and the amount of anions generated is small. In the case of 50% by weight or more, flame retardancy can be secured, but the performance of the paint is significantly reduced.

The radioactive element-containing material is also preferably contained 5 to 50% by weight relative to 100% by weight of the paint. When it is added below 5% by weight, the anion generation is small. When it is contained above 50% by weight, the generation of anions is large, but it is unreasonable in terms of price.

Hereinafter will be described an embodiment of the present invention.

Example 1

100% by weight of acrylic resin contained radioactive elements as a substance containing 15% monazite powder and 15% ammonium monophosphate to prepare a paint imparted with anion generation and flame retardancy.

Example 2)

100% by weight of the fluorine resin contained radioactive elements as a substance containing 15% of monazite powder and 20% of ammonium monophosphate to prepare a paint provided with anion generation and flame retardancy.

Example 3

100% by weight of fluorine resin contained radioactive elements as a substance containing 25% of vastene powder and 30% of ammonium monophosphate to prepare a paint imparted with anion generation and flame retardancy.

The present invention is not limited to the above-described specific embodiments, and various modifications can be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims. Such changes are intended to fall within the scope of the claims.

Since the functional paint according to the present invention uses a flame retardant as an anion generating material, it is possible to prepare a paint imparting flame retardancy as well as anion generation without using an additional anion generating material. Therefore, it is possible to provide a paint having an additional value at a low cost while simultaneously generating anion and flame retardancy.
