Description

ADHESIVE FOR CORRUGATED CARDBOARD CONTAINING NON-METAL MINERAL AND CORRUGATED CARDBOARD BOX USING THE ADHESIVE}

The present invention relates to a starch pool containing zeolite, elite and bentolite processed in a predetermined process and a cardboard box using the same, which maintains the freshness of agricultural and aquatic products stored in the cardboard box for a long time, It is to enable the removal of residual pesticides so that agricultural products can be stored for a long time in good storage condition.

Corrugated cardboard boxes used in the distribution of agricultural and marine products are generally manufactured by bonding the outer and front of the corrugated core to the outside and then bonding the printed manila or roe deer on the outer surface.

On the other hand, harmless starch paste is mainly used when bonding the core core and the outside and the outside, and the starch paste is excellent in adhesive strength, but it does not help to absorb or insulate during the winter and summer seasons, even when generating various gases such as carbon dioxide gas. There is a disadvantage that it does not maintain good storage conditions of agricultural and marine products stored in a cardboard box because it does not absorb or decompose.

That is, the conventional cardboard box using the starch pool does not smoothly provide the appropriate amount of air necessary for the preservation of agricultural and aquatic products, and does not easily remove carbon dioxide and other harmful gases, and also has a poor taste of agricultural and aquatic products due to lack of insulation or moisture absorption. The fragrance is easy to fall off, it does not inhibit the occurrence of mold, etc., there is a disadvantage that easily decay.

On the other hand, in order to solve this problem, there is a case in which zeolite, which is harmless to the human body and excellent in physical adsorption and chemical cation substitution, has been applied for the preservation of agricultural and aquatic products, but various non-metallic minerals have different activities and the unit cost in manufacturing is also different. In order to maintain the freshness of agricultural and marine products and to extend the storage period, it was urgent to obtain the composition ratio of non-metallic minerals to maximize the effects such as absorption of moisture, deodorization of harmful gases and emission of far infrared rays, and to lower manufacturing costs as much as possible.

An object of the present invention is to provide a cardboard box adhesive and a cardboard box using the same, which is devised to solve the problems described above, which is harmless to the human body and contains a nonmetallic mineral having excellent physical adsorption and chemical cationic substitution.

In order to achieve the above object, the adhesive for cardboard boxes containing the non-metallic mineral of the present invention is 70 to 75% by weight of starch paste, 20 to 15% by weight of zeolite pulverized to 300 mesh or less after high temperature vacuum dehydration and removal of impurities. And 7.5 to 5% by weight of illite and 7.5 to 5% by weight of bentorite after the removal of impurities.

On the other hand, in order to achieve the above object, the cardboard box using the cardboard box adhesive containing the non-metallic mineral of the present invention, starch paste 70 to 75% by weight, high temperature vacuum dehydration on the contact surface of the outer core and the corrugated core And an adhesive comprising 20 to 15% by weight of zeolite pulverized to 300 mesh or less after removal of impurities, 7.5 to 5% by weight of illite and 7.5 to 5% by weight of bentorite after drying and removal of impurities. The lower limbs, the corrugated cardboard and the upper limbs are characterized in that they are manufactured using corrugated cardboard.

According to the present invention as described above to maintain the proper humidity and temperature of the agricultural and aquatic products stored in the cardboard box by providing the absorption and insulation effect, and to maintain the storage environment of agricultural and aquatic products by providing the adsorption effect of odor and other gases, By providing the removal effect of residual pesticides, it not only helps to maintain the quality of the stored agricultural and aquatic products, but also maximizes the freshness and storage period of the agricultural and aquatic products stored due to the emission of far infrared rays.

Hereinafter, with reference to the accompanying drawings will be described in detail a cardboard box adhesive containing a non-metallic mineral and a cardboard box using the same.

Figure 1 is a reference view showing the outline of the corrugated cardboard box using an adhesive for a cardboard box containing a non-metallic mineral, Figure 2 is a perspective view showing a bonding structure of the cardboard applied to the present invention.

According to the enlarged view of the corrugated cardboard box shown in the upper right of Figure 1 corrugated cardboard is made up of (10a) facing the inner surface of the box and the outer shell 10b facing outward and the corrugated core 30 bonded therebetween. On the other hand, the cardboard box adhesive 20 is applied to bond the (10a) and the corrugated cardboard 30, and the cardboard box adhesive 20 is applied to bond the outer shell 10b and the corrugated cardboard 30 as well. .

On the other hand, if necessary, a plurality of vents 11 may be formed on one side of the cardboard box and a surface thereof to help ventilate the cardboard box. Alternatively, as shown in FIG. 2, a plurality of vents 11 may be formed only in (10a) in order to increase adiabatic effect rather than venting, and to maximize a sorption effect by a cardboard box adhesive 20 containing a non-metallic mineral. It may be.

At this time, the cardboard box adhesive 20 using a non-metallic mineral is composed of starch paste, zeolite, illite and bentorite as main components.

Zeolite is a mineral produced by the action of hot volcanic ashes of three new generations by hydrothermal action.The unit crystals are pulverized into needles or granules when crushed, and they are microporous and have a large number of pores. It is excellent in chemical cation substitution and absorbs and adsorbs water and gas. The chemical formula is (Na 2, Ca) (Al 2 SiO 18) 6 H 2 O, and Mordenite is Na (AlSiO 5 O 12) 3 H 2 O.

On the other hand, zeolites are non-toxic to humans or crops, and can utilize the inherent physical adsorption and chemical cation substitution properties to enjoy the effect of adsorption and dehumidification of residual pesticides and gases.

The illite, on the other hand, is a mica mineral belonging to the monoclinic system. The chemical formula is (K, H 3 O) Al 2 (Si, Al) 4 O 10 (H 2 O, OH) 2. It is produced in aluminium-rich heterogeneous or tuff sedimentary rocks, and is produced as an altered mineral of hydrothermal deposits. Illite has excellent adsorption, deodorization, and degradability for heavy metals and harmful gases, and excellent ability to emit anion and far-infrared rays with 7 ~ 13㎛ wavelength at room temperature.

Bentonite is a clay mainly containing montmorillonite, a mineral belonging to a monoclinic system having a crystalline structure such as mica. Bentonite is excellent in cation adsorption, in particular in absorbency and swelling.

Looking at the manufacturing process of the cardboard box adhesive 20 using a non-metallic mineral according to the present invention.

First, the zeolite is vacuum dehydrated at high temperature, impurities are removed, and then finely pulverized to 300 mesh or less. During the high temperature dehydration process, a large number of pores in the crystal of zeolite are formed well, and have a strong adsorption force on molecules that can pass through the pore inlet.

On the other hand, after collecting the illite and bentonite, the moisture content is dried to 7-10%, and then subjected to an impurity removal process, and similarly pulverized finely below 300 mesh. Illite is buried abundantly in Yeongdong-gun, North Chungcheong Province. Bentonite is generally pulverized to a sand thickness due to cost problems, but in the present invention, it is pulverized to 300 mesh or less like zeolite and illite.

Dry pulverized zeolite, illite and bentonite are mixed in a starch paste prepared in advance. Thus mixed cardboard box adhesive has a component ratio of 65 to 75% by weight starch paste, 20 to 15% by weight zeolite, 7.5 to 5% by weight illite and 7.5 to 5% by weight bentonite. The component ratio as described above is an optimum condition derived in consideration of the absorption and heat insulation effect, the odor and the adsorption effect of residual pesticides, the amount of far-infrared radiation and the manufacturing cost based on the experimental results.

Using a cardboard box using a cardboard box adhesive containing a non-metallic mineral as described above was able to obtain the following experimental results.
