Description

The present invention relates to a film-like gas adsorption / sustained release material and various substrates using the same. More specifically, the present invention relates to a film-like gas adsorption / sustained release material used for deodorization, interior / bedding, household goods or distribution-related base materials.

It is a very important technique to store and transport agricultural products after harvesting while maintaining good freshness. In particular, fumigation processing equipment and refrigeration equipment are being prepared to suppress ripening due to ethylene gas, but because it uses harmful gas or large equipment, it is costly or small There are many restrictions such as difficult things and things that cannot be done anywhere. On the other hand, in order to adsorb ethylene gas, methods using bamboo-derived substances, Otani stone, diatomaceous earth, and activated carbon have been proposed, but the effect is insufficient. Also, a metal salt coordinated to cross-linked polystyrene has been proposed (see, for example, Patent Documents 1, 2, and 3). However, the use of heavy metal makes the adsorbent come into contact with food or the like to be transported. This is not only a problem for use in food transportation, but also has the disadvantage of causing secondary pollution during disposal of the substrate. Moreover, since the hermeticity of the house has increased, it is also important to take measures against the so-called sick house (school) syndrome caused by harmful gases such as toluene, which are present in a small amount in the living space. Recently, by regulating the raw materials used, the concentration of toxic gases has been considerably suppressed, but it is still reported that problems are often occurring. A method using diatomaceous earth, activated carbon, bamboo charcoal, etc. has been proposed, but the effect is insufficient, and because it is dark, it is difficult to color it to your favorite color, it can only be in the form of paint or board It is difficult to commercialize and there is a lack of flexibility in product form.

Japanese Patent Publication No. 3-79971 Japanese Patent No. 2553878 Japanese Patent No. 2589499

The present invention provides a gas adsorption / sustained release material that is highly efficient, white (easy to be colored), low in price, safe and simple to use, and low in pollution during disposal.

The present inventor considered Patent Documents 1, 2, and 3, and as described in the patent, the ethylene gas once adsorbed to the crosslinked polystyrene was released to the outside again due to the rise in the temperature of the outside air. It has been found that if there is enough effective adsorbent, it is difficult to occur at a normal room temperature level (for example, 10 to 35 ° C.). In the example of the patent, the adsorbent is sufficient in terms of apparent quantity. However, it is considered that the number of sites where ethylene gas can be adsorbed is reduced because the metal salt is complexed at the benzene ring site where ethylene gas is adsorbed. Further, in the adsorbent, the surface area of the outer layer of the particles is an important factor as well as the micro surface area inside the particle. In the fixing method of the adsorbent of the patent, for example, the surface of the adsorbent is covered with an adhesive or fixed in a lump state, so that the function of the adsorbent is not likely to be sufficiently developed. Is also considered to be a cause. It is also important that the adsorbent is fixed in its packaging system so that the adsorbent does not touch the object to be transported even if the package is torn. When fixed in a lump state as in the embodiment of the patent, if the packaging is torn, the adsorbent may spill out and touch the object to be transported. Therefore, the present inventor uses divinylbenzene polymer fine particles without complexing a metal salt, maximizes the outer surface thereof, and makes the adsorbent contact the transport object in any case. Thus, the present inventors have studied a method for fixing to a film-like material, and have reached the present invention.

The gas adsorption / sustained release material of the present invention and various substrates using it are suitable for deodorization, interior / bedding, household goods or packaging / distribution-related substrates, high efficiency, low cost, and easy to use, It is easy to dispose and can be produced in a simple way.

The present invention will be described in detail below. As the divinylbenzene polymer fine particles used in the present invention, Diaion HP20, 21 or Sepabeads SP825, 850 commercially available from Mitsubishi Chemical Corporation can be used. These are water-insoluble fine particles having many hydrophobic fine pores, and have a high ability to adsorb hydrocarbons or highly organic substances. The particle size distribution is 90% over 250 microns, the specific surface area is 500 to 1000 m 2 / g, the most frequent pore size is 30 to 300 mm, and the pore volume is 1.0 to 1.5 ml / g.

As the hydrotalcite used in the present invention, Kyoward 200, 300, 500, 1000 and the like commercially available from Kyowa Chemical Industry Co., Ltd. can be used.

These are fine particles of 20 to 500 microns, but if necessary, they can be pulverized to atomize the aggregates.

The above-mentioned divinylbenzene polymer or hydrotalcite fine particles (hereinafter abbreviated as “fine particles”) are characterized by their properties, the surface of the particles being covered in some form, or the particles becoming clumped together. Therefore, it is necessary to devise so that the particle surface is exposed. For example, the following method is effective.
In the papermaking stage, fine particles are swallowed.
The upper and lower two sheets of paper, cloth, non-woven fabric or porous plastic film are fractionated and sewn so that fine particles are sandwiched between the fractions.
Sprinkle fine particles on paper, cloth or porous plastic film pre-coated with adhesive (adhesive) to a thickness of 100 microns or less, and then sandwich paper, cloth or porous plastic film on top of it. .

In consideration of the influence on the adsorbent, an aqueous base is preferable.

In the present invention, the amount of fine particles added is 5 to 70 g / m 2 with respect to the area of the gas permeable material. When it is less than 5, the effect is absolutely poor, and when it is more than 70, the cost performance is lowered.

Examples of the halogen acid salt used in the present invention include sodium hypochlorite and potassium iodate. These anion roots have high oxidizing power, are unstable themselves, and decompose the support, so that they are combined and stabilized by incorporating them between the layers of hydrotalcite. Specifically, a complex is obtained by adding a fine powder of hydrotalcite to an aqueous solution of a halide salt and performing anion exchange. Sodium hypochlorite has a high sterilizing power and is effective during transportation of vegetables, and potassium iodate is effective in oxidative decomposition of ethylene. The amount of hydrotalcite used with respect to the halide salt is 2 to 20 weight ratio. If it is less than 2, it is unstable, and if it is more than 20, the oxidizing power is reduced.
The complex is pulverized as it is or as necessary, and is fixed as a fine film in the same manner as the divinylbenzene polymer fine particle.
