Hereinafter, each component of the additive contained in the aqueous coating agent will be described.
(Pyroelectric powder and piezoelectric powder)
The pyroelectric material is a material that generates heat when receiving heat energy, and the piezoelectric material is a material that generates charge when receiving pressure. A pyroelectric material generally has a piezoelectric effect and is included in the piezoelectric material. Therefore, in the present invention, it is not necessary to strictly distinguish the pyroelectric body and the piezoelectric body.

  Typical examples of pyroelectric materials and piezoelectric materials include barium titanate, lead zirconate titanate, potassium niobate, and bismuth sodium titanate, but are not limited to these materials, and materials having piezoelectricity For example, piezoelectric polymer material powder, metal powder, silicon carbide powder, silicon powder, tourmaline, quartz, and the like may be used. Also, two or more of these materials can be used in combination.

  The pyroelectric body and the piezoelectric body are used in the form of powder in the present invention. By making the powder fine, dispersibility in water is improved. The average particle size of the powder can be about 3 μm or less. If the average particle size exceeds about 3 μm, the color of each powder affects the calcium hydroxide paint and coating agent, which is not preferable. Although it does not specifically limit about a minimum, Since manufacturing cost rises so that it makes fine, it can be set to about 0.5 micrometer or more. In the examples described later, those having an average particle diameter of 3 μm were used.

  In the additive of the present invention, the amount of pyroelectric powder and piezoelectric powder to water is not particularly limited. Pyroelectric powder and piezoelectric powder are sufficiently dispersed in water, and have the effect of decomposing volatile organic compounds when the additive of the present invention is used as a calcium hydroxide paint, adhesive or coating agent It can be an amount.

The metal complex, the metal powder, and the metal ion transfer charges generated from the pyroelectric body or the piezoelectric body, and generate holes in the pyroelectric body or the piezoelectric body. In the metal powder, the charge received from the pyroelectric body or piezoelectric body reacts with oxygen in the air to generate superoxide.

  Examples of the metal complex, metal powder, and metal ion include a copper complex, copper powder, or copper ion. Copper has good conductivity and antibacterial action. Therefore, by including a metal complex, copper powder, or copper ion in the additive of the present invention, not only the above-described effect of generating holes but also the effect of preventing mold generation. Therefore, it is useful for improving the health of residents in the home using the system containing the additive of the present invention. Furthermore, the metal complex, copper powder, or copper ion is less expensive than platinum or the like. Note that a plurality of metal complexes, copper powders, and copper ions may be included in the additive of the present invention. As for the water containing a metal complex, cupric tartrate water is mentioned, for example.

  In the additive of the present invention, the compounding amount of the metal complex, metal powder and metal ion with respect to water is not particularly limited. It can be determined as appropriate according to the amounts of pyroelectric powder and piezoelectric powder described above.

As the holding agent or dispersant, for example, zeolite or silicon oxide can be used. Moreover, a binder, an adhesive agent, etc. can be contained in the additive of this invention according to a use.

[Production method]
The additive of this invention can be manufactured by making water contain each above-mentioned component.

  In the air-conditioning indoor environment cleaning system 10, 20 of the present embodiment, a coating film of the aqueous coating agent is formed on the surface by applying the aqueous coating agent containing the above-described additive to the inner surface of the air filter or device, This coating film has an effect that the VOC gas in the air is decomposed by the circulating energy of the air and the air can be purified. In other words, the air filter or the inner surface of the device is applied as a more effective location that receives the circulating energy of air.

  Moreover, the air-conditioning type indoor environment cleaning systems 10 and 20 of the present embodiment are provided with a coating film of an aqueous coating agent containing the above-mentioned additives on the inner surface of the air filter or equipment of the air-conditioning type indoor environment cleaning systems 10 and 20. The surface of the wall near the air outlet that receives the airflow from the air outlets 14 and 24, the surface of the ceiling connected to the wall, or both the surface of the wall and the surface of the ceiling A coating film of an aqueous coating agent containing the additive can be formed, or the wall and / or ceiling near the outlets 14 and 24 can be made into a finishing material containing the aqueous coating agent containing the additive. . Then, even with a slight air flow from the air outlets 14 and 24, the wall near the air outlet contributed to air purification and was applied to the equipment of the air-conditioning indoor environment cleaning systems 10 and 20. Combined with the air purification by, the rooms 1 and 2 can be further cleaned. Furthermore, by providing the booster fan 19 at the outlets 14 and 24, the airflow from the outlet can be increased, and the rooms 1 and 2 can be further cleaned.

  The compounding amount when the additive of the present invention is added to an aqueous coating agent or a calcium hydroxide paint can be appropriately determined according to these uses. In one example, considering the decomposition effect of volatile organic compounds, the pyroelectric powder and the piezoelectric powder are about 1 to 3 g per square meter when applied to the surface of wallpaper or calcium hydroxide paint. It can be made into the compounding quantity.

The effect of the air-conditioning indoor environment cleaning system of the present invention will be clarified by experimental data.
An additive for interior material containing 100 g of tourmaline powder in 1000 cc of cupric water tartrate (800 ppm) was prepared. 630 cm ³ of this interior material additive was added to 500 g of calcium hydroxide paint and kneaded to obtain a coating material. A test piece was prepared by applying this coating material on a base paper and pasting it on an aluminum plate (3 mm thick). The dimension of the test piece was 165 mm × 165 mm × 3 mm.

Two test pieces were prepared, and a reduction test of formaldehyde was performed according to JSTM H 5001 (a test method for reducing performance of building materials for reducing indoor air contamination concentration by a small chamber method). The volume of the small chamber in this test was 20 L, the sample loading rate was 2.2 m ² / m ³ , and 100 μg / m ³ concentration of formaldehyde was continuously supplied into the small chamber at 167 mL / min using a seal box. The air after the first, third, and seventh days from the start of the test was collected at the small chamber outlet. Moreover, the air after 1 hour, 3 hours, 7 hours, and 24 hours after formaldehyde supply stop (airflow stop) was collected at the small chamber exit.

Formaldehyde feed in small chamber one day after the test started, formaldehyde concentration in a small chamber inlet concentration of formaldehyde small chamber outlet is 108μg / m ³ was 27 [mu] g / m ^3.
The formaldehyde supply to the small chamber 3 days after the start of the test was 106 μg / m ³ at the inlet of the small chamber and the formaldehyde concentration at the outlet of the small chamber was 47 μg / m ³ .
Formaldehyde was supplied to the small chamber 7 days after the start of the test. The formaldehyde supply concentration at the small chamber inlet was 109 μg / m ³ and the formaldehyde concentration at the small chamber outlet was 53 μg / m ³ .
From the above results, it was found that the formaldehyde concentration was reduced by the test piece.

An additive for interior material containing 100 g of tourmaline powder in 1000 cc of cupric water tartrate (800 ppm) was prepared. 630 cm ³ of this interior material additive was added to 500 g of calcium hydroxide paint and kneaded to obtain a coating material.

  This coating material was applied twice to 6 sheets of 30 cm square fireproof boards and dried. The fire-resistant board after drying was affixed to each of the six inner surfaces of a hollow rectangular parallelepiped sealed container to obtain a specimen.

  A formalin container with a lid opened was placed in the specimen, and the sealed container of the specimen was sealed. Subsequently, it heated and made the temperature in a test body into 40 degreeC. While maintaining the temperature of 40 ° C., the formaldehyde concentration and carbon dioxide concentration in the specimen were measured every 3 hours using a Kitagawa gas detector.

As a result, the formaldehyde concentration was 30 ppm at the initial value, 10 ppm after 3 hours, 5 ppm after 6 hours, and a trace amount after 9 hours.
The initial carbon dioxide concentration was 1000 ppm, 3400 hours after 1400 ppm, 6 hours after 1600 ppm, and 9 hours after 2000 ppm.
The heating of the specimen was stopped, the formaldehyde concentration after standing for 10 days was 0 ppm, and the carbon dioxide concentration was 500 ppm.

  From the above results, it was found that the concentration of carbon dioxide increases as formaldehyde decreases. This is considered because formaldehyde absorbed in the coating material was decomposed by the additive for the interior material.
