Description

Anionic adhesive and method for producing the same

The present invention relates to an anion adhesive and a method for producing the same, and more particularly, to an anion adhesive added with a natural anionic material capable of emitting far infrared rays and anions to a starch paste and a method for producing the same.

Normally, organic adhesives are used for the interior coating of buildings, which have excellent adhesion but are toxic and difficult to carry out. It has been found to harm the human body, and there is an urgent need for a pollution-free adhesive comparable to that of an organic adhesive.

In addition, recently, anionic inorganic materials such as charcoal, jade, elvan, and loess radiate far infrared rays and anions that are beneficial to the human body to purify the surrounding air, remove odors, inhibit the growth of mold and harmful bacteria, and block water veins and electromagnetic waves. It has been found to contribute greatly to the health of the human body, such as preventing diseases, attracting sensational attention.

Therefore, even in beddings and building materials such as duvets and beds, super badges, papers, flooring materials and interior materials containing anionic inorganic materials such as charcoal are already on the market.

However, when the inorganic materials such as charcoal, jade, ganban stone and loess, which emit far infrared rays and negative ions are fixed to the super medium, wallpaper, flooring or building interior materials by natural adhesives, the adhesive strength decreases, so that the human body or object may be exposed to these super medium, wallpaper or building interior materials. In case of brushing, this inorganic material powder gets on your hands or clothes, which makes your work inconvenient.

However, when the inorganic material is fixed by the organic adhesive, as described above, it prevents the release of harmful substances as well as prevents micropores of the inorganic material including charcoal attached to the super medium or wallpaper and flooring material, so that moisture control is not achieved. As a result, the wallpaper floats and mold grows to shorten the lifespan of the wallpaper, and above all, the disadvantage of lowering the performance of the inorganic material is inherent.

In light of these current trends, the inventors of the present invention have also concentrated their efforts to develop a pollution-free adhesive that is beneficial to the human body, and is inexpensive and easy to work with. Therefore, by using the properties of existing starch pastes, such as jade, elvan, loess, etc. By adding the powder of anionic inorganic material in a special way, it is not only pollution-free and superior to the adhesive strength of the organic adhesive, but also the manufacturing process is simple and the unit cost is low, and the application of the adhesive to the paper and super medium can be easily performed. We have developed an adhesive that can improve your health.

According to the present invention, there is provided an anionic adhesive, characterized in that an additive mixture composed of 5 to 40% by weight of an anionic inorganic substance, a natural flavor and a mold generating inhibitor is added to a gelled starch paste.

The anionic adhesive according to the present invention is added to the starch while stirring slowly 3 to 5 times of water to make a slurry (slurry) state and then gradually heated to convert the starch to gel state and then cooled slowly below 30 ℃, cooling 1 to 5 to 40% by weight of the mixture of anionic inorganic substances, natural fragrances and mold-generating inhibitors mixed with each other in a mixed state, and then cooled and gradually cooled. It is characterized by producing an anionic adhesive.

As the starch used in the present invention, various starches such as flour, potato, corn, etc. are used, and water is added to the starch dough while stirring at an amount of 3 to 5 times the weight of the starch.

Anionic inorganic materials, which occupy almost all of the additive mixtures, may typically include porous charcoal, and other examples may be used alone or in combination of two or more thereof. It is applied in a powder state of about 200 to 500 mesh.

In addition, various flavorings such as sol, juniper, lemon, etc. are applied as the fragrance in the additive mixture, pentachlorophenol (PCP) and its sodium salt, salicylic anilide (brand name: shilan) , Bis (5-chloro-2-oxyphenyl) methane, p-nitrophenol-based fungal inhibitors are mixed with the anionic inorganic substances in an amount of about 5% by weight or less based on the weight of the anionic inorganic substance .

These additive mixtures are poured into the powdered anionic inorganic material by pouring a liquid flavoring agent and a mold inhibitor, and then left to stand for 1 day to allow the fragrance and mold inhibitor to sufficiently penetrate between the pores of the inorganic material such as charcoal.

That is, the anionic adhesive according to the present invention is added to the starch while stirring slowly 3 to 5 times of water to make a slurry state and then heated to about 60 ℃ or more to convert the starch into a condensed gel state Thereafter, the mixture is gradually cooled to about 30 ° C.

In addition, the additive mixture to be mixed with starch is first put the fine powder of the anionic inorganic material in a sealable container, a very small amount of natural fragrance and mold generation inhibitors, mixed well and left to stand for 1 day.

The anionic adhesive of the present invention is prepared by adding 5-40% by weight of the additive mixture to the cooled gelled starch based on the weight of the starch filler, and mixing and stirring the mixture to cool.

If the application amount of the anionic inorganic material is less than 5% by weight, far infrared rays and anion radioactivity are weak, but if more than 40% by weight, the anionic inorganic material may be released, which is inappropriate. In addition, the additive mixture must be added at a low temperature of 30 ° C or less because it may be volatilized at a high temperature.

By doing this, the starch and the anionic inorganic material are separated from each other and do not sink or form lumps.

The anionic adhesive of the present invention prepared by the above-described method is a starch which is a high molecular compound of three-dimensional network structure in which the powder of anionic inorganic material (1) is gelatinized as schematically illustrated in FIG. It is not impregnated into the voids 2 but is attached to the connection point 3 of the mesh to form one coating layer.

That is, when the starch is gelatinized and condensed in a gel state, the starch forms a porous network structure and forms a thin film. Therefore, in this state, when the fine powder of anionic inorganic material is injected and further coagulates, the fine powder is generally made of the network structure. It is firmly fixed to the connection point, and the anionic inorganic material can be surely functioned since the fine pores are not blocked by the starch paste.

Therefore, the anionic adhesive according to the present invention is manufactured to achieve the above-described specific structure, so that it has an adhesive force almost equivalent to that of the existing organic adhesive, and can firmly retain the anionic inorganic material, while almost blocking fine pores of the anionic inorganic material. It does not reduce the function of the anionic inorganic material.

Although an example is given and demonstrated so that this invention may be understood more clearly below, this invention is not limited to this Example, A change and correction are possible within the range of the scope of this invention and the range of a claim.

First, oak charcoal is pulverized very finely and put in a sealable glass bottle, and the scent of fragrance and bis (5-chloro-2-oxyphenyl) methane are added in 1 wt% and 4 wt%, respectively, based on the weight of the oak charcoal powder. The mixture was added, mixed well, sealed, and left at room temperature for 1 day to prepare an additive mixture to be added to the starch paste.

On the other hand, 5 times of water was added to the starch while stirring to make it into a slurry state, and it heated and gelatinized at the temperature of 60 degreeC or more. The anhydrous adhesive of the present invention was prepared by slowly cooling the gelatinized starch to 25 ° C. and condensing the gel slightly. Then, the prepared additive mixture was added 34 wt% based on the weight of the starch paste, stirred, and further cooled.

The anionic adhesive prepared above was applied to the paper medium in a conventional manner without dilution.
