Description

Method for manufacturing melanin decorative plate having an insect repellent effect {Method of manufacturing a mothproofed melanin decoration panel}

The present invention relates to a method for producing a decorative plate having an insect repellent effect, and more particularly, to a method for producing a melanin cosmetic plate which allows an inorganic compound having excellent insect repellent effect to be uniformly distributed.

Recently, as the interest in hygiene has increased due to the improvement of living standards and the deepening of environmental pollution, the demand for insect repellent functionality is gradually increasing for the decorative boards used in desks and sinks as well as flooring and wallpaper.

In other words, living spaces inhabited by many people, such as apartments, apartments, buildings, and hospitals, are suitable conditions for insects to grow, and diseases such as respiratory and digestive diseases may be caused by harmful insects such as cockroaches. Insect repellent is also required for the makeup plate used in the sink and close to life.

In accordance with such a request, the present inventor invented the "insect functional flooring decorative material" and filed it with the patent application No. 94-24285. The present invention has incorporated an inorganic insect repellent into the floor decorative material to impart the insect repellent function. In order to exhibit an excellent insect repellent effect, the method of manufacturing the floor decorative material was applied to the process of manufacturing a decorative plate to produce a decorative plate having an insect repellent function.

However, when the inorganic insect repellent was added to the melanin resin during the manufacturing process of the melanin cosmetics, deposition problems of the inorganic insect repellent occurred, and thus, the overall uniform properties could not be obtained.

Accordingly, an object of the present invention is to provide a method for preparing an insect repellent decorative plate using the additive which improves the dispersibility of the inorganic insect repellent in the melamine resin, thereby solving the deposition problem.

In the method of manufacturing a decorative plate having an insect repellent effect, which is an object of the present invention, the impregnating step of the first impregnating resin, the second impregnating resin and the third impregnating resin and curing each of the backing paper, the printing paper and the surface paper, respectively In the manufacturing method of the decorative plate comprising the step of forming the back layer and the print layer and the surface layer to be pressed and the step of integrally pressing the back layer, the print layer and the surface layer, before the impregnation step, for the first impregnation It is characterized in that the addition of a predetermined inorganic repellent and dispersant to any one or both of the resin and the third impregnation resin.

The insect repellent effect of the plate made by this manufacturing method was proved through the test of evasion rate through ticks and cockroaches.

Explanation of symbols on the main parts of the drawings

1: back layer 2: printed layer

3: surface layer 4: inorganic insecticide

Hereinafter, described in detail with reference to the accompanying drawings, the present invention.

Melanin board according to the present invention is a step of impregnating the first impregnated resin, the second impregnated resin and the third impregnated resin, the curing step of the predetermined inorganic insect repellent and propellant and the backing paper, printing paper and surface paper, respectively The back layer, the print layer and the surface layer to be made through the forming step and the lamination step of integrally press-processing the back layer, the print layer and the surface layer is manufactured.

That is, the back paper, the printing paper, and the surface paper are impregnated in the first impregnating resin, the second impregnating resin, and the third impregnating resin, respectively, and cured to form the back layer, the print layer, and the surface layer, respectively. Inorganic insect repellent having an average particle size of 1 to 3 µm in any one or more of the first impregnation resin, the second impregnation resin, and the third impregnation resin before the impregnation resin is impregnated. And then, in order to improve the dispersibility, 0.1 to 2% by weight, preferably 0.1 to 0.5% by weight of the predetermined amount of the dispersant in order to improve the dispersibility to prepare a decorative plate of the present invention.

In this case, the reason why the inorganic repellent is not directly added to the surface layer is that the inorganic compound having a large specific gravity is not evenly dispersed in the resin while being deposited during the manufacturing process. In addition, the particle size distribution of the inorganic insecticide can be finely dispersed in the resin. However, if the particle size distribution is too fine, handling of the inorganic insecticide becomes inconvenient, and the manufacturing process is difficult, resulting in difficulty in the manufacturing process. Limited to 3 μm.

As such, the content of the inorganic insecticide having the particle size distribution is about 0.1 to 10% by weight, more preferably about 0.3 to 3% by weight, based on the weight of the impregnating resin used to prepare each layer.

For example, when the inorganic insecticide is included only in the surface layer, the inorganic insecticide may be included in the amount of the above-described weight% based on the weight of the third impregnating resin (usually melanin resin is used) to impregnate the surface paper.

1 is a schematic cross-sectional view showing an example of a conventional conventional makeup plate, which is a surface layer 3 formed by impregnating surface paper with a first impregnating resin, and a printing layer formed by impregnating printing paper with a second impregnation resin ( 2) and the backing layer 1 formed by impregnating the backing paper in the third printing layer, and FIG. 2, in contrast to this, uses SIB-500 manufactured by Nishi Chemical Co., Ltd. as an inorganic insect repellent according to the manufacturing method of the present invention. As a cross-sectional view of a makeup plate manufactured using Disper BYK-190 of BYK Chemie, Germany, it shows that the inorganic insecticide 4 is evenly dispersed in the surface layer 3.

In order to test the insect repellency of the melanin board prepared as described above, the following evasion rate test.

Melanin board and ordinary melanin board of the present invention is cut to a size of 7cm × 7cm and placed in a paper box of 20cm in height, 26cm in width, 16cm in height while the inside of the resin-treated paper facing the test sample and untreated sample.

On these samples, each part was attached to four corners of the same size veneer plate, and a 5 cm x 5 cm shelter was installed between the sample surface and the veneer plate to freely move the cockroach, and 20 cockroaches were cut into onions and cookies. Put it in a paper box with food such as water.

The cockroach feeds in a box and enters a dark shelter, and the evacuation rate is calculated by counting the number of roaches lurking in the treated and untreated shelters after 24 hours of testing.

The test results are shown in Tables 1 and 2 below.

TABLE 1

Comparison test results between the sample added with 1.0% by weight of inorganic insecticide and the untreated

TABLE 2

Contrast test result of the sample added with inorganic insecticide 2.0% by weight

As shown in the above table, the melanin decorative plate to which the inorganic insect repellent was added proved to have an insect repellent effect.

As described above, the melanin decorative plate manufactured according to the present invention uses an impregnating resin and an inorganic repellent having a particle size distribution having excellent dispersibility, and also has a good insect repelling effect by using a predetermined dispersant, and at the same time, the problem of depositing and dispersing the insect repellent. Degradation problems, etc. will be significantly reduced.
