Description

Antibacterial paste composition {ANTI-FUNGI STARCH COMPOSITION}

[Industrial use]

The present invention relates to a antibacterial pool composition, in particular, antibacterial and antimicrobial agents, such as antimicrobial agents are formulated as an effective ingredient, excellent antibacterial power and its sustainability and has a biological antibacterial function that is not harmful to humans and livestock It relates to a mycelium composition.

[Prior art]

There are tens of thousands of microorganisms on the planet, and especially fungi are distributed anywhere on the earth, damaging the interior and exterior of buildings and hindering their aesthetics. In addition, allergic syndrome, such as bronchial asthma, mycotoxin poisoning, or fungal infections can cause diseases in humans and livestock, and deterioration of food or drugs, damage to the material and performance of industrial products, etc. The damage varies. In addition, mold lives well in places with high humidity and organic substances, and there is a difference in distribution according to each region, and there are molds that are commonly distributed in hospitals, houses, hotels, food factories, or entertainment establishments. It is reported that some molds live in limited numbers (Korean Journal of Mycology, Vol. 12, No. 4, pp. 183 ~ 188).

General starch paste is manufactured by mixing strong acid and strong alkali such as formalin, hydrochloric acid, sulfuric acid and caustic soda, which are very dangerous to the human body and can cause fatal damage, but it does not prevent the formation of mold. Property and time loss, such as defect repair due to the occurrence of mold in the field occurs, and it is not provided with comfort of indoor environment by harmful substances or mold during or after work.

In particular, mold may occur due to moisture absorption of gypsum board or insulation material of underground buildings or apartments, or wetting of gypsum board paper or wallpaper, which has been constructed together, thereby degrading the function of building materials such as gypsum board, or applying wallpaper after applying wallpaper. The mold continues to be generated, contaminating the wallpaper surface or causing disease by the mold, resulting in a lot of loss of property and time.

In order to solve this problem, there is a method of spraying a sterilizing material, but when spraying, the sterilizing material can be scattered and damage to humans or livestock, and the effect is temporary.

In addition, coating the anti-bacterial paint solves this problem, but there are materials such as pigments, resins, and various additives in the paint components. Redundancy has been pointed out as a disadvantage.

In addition, an inorganic antibacterial pool prepared by mixing an inorganic antibacterial powder prepared by substituting silver ions with inorganic powders such as silica, alumina, iron oxide, titanium oxide, magnesium oxide, calcium oxide, and the grass component of sodium carboxymethylcellulose in water is disclosed. Although it is known in Korean Patent Publication No. 97-6446, it is difficult to prepare a uniform composition because the inorganic antimicrobial powder is an inorganic substance, and the antimicrobial effect of silver ions is effective only against bacteria, and is effective against antifungal properties. Is not known, and the use of silver ions greatly increases the manufacturing cost, and it is difficult to dissolve carboxymethyl cellulose sodium in water in a short time, which influences the adhesion performance. Therefore, there is a problem that the initial adhesive strength is low.

In view of the problems of the prior art, it is an object of the present invention to provide a novel antibacterial pool composition that exhibits a wide range of antibacterial power against mold or forms molds in buildings and maintains antibacterial power for a long time.

Another object of the present invention is to provide a fungal paste composition which does not generate mold even under ambient moisture absorption conditions after adhesion drying.

Still another object of the present invention is to provide an antibacterial pool composition having excellent antibacterial power which is not harmful to humans or livestock.

Another object of the present invention is to provide an antibacterial pool composition which can be easily used by anyone, and is excellent in adhesion to subsequent wallpaper construction.

[Means for solving the problem]

The present invention to achieve the above object,

a) starch; b) surfactants; And c) fungicides

It provides a antibacterial pool composition comprising a.

In another aspect, the present invention provides a antimicrobial pool composition further comprising d) an emulsion synthetic resin in the composition.

The present invention also provides an antibacterial pool composition further comprising e) water in the compositions.

In the composition, the composition ratio is

a) 1 to 40 parts by weight of starch;

b) 0.05 to 0.3 parts by weight of surfactant;

c) 0.1 to 5 parts by weight of antiseptic;

d) 50 parts by weight or less of an emulsion synthetic resin; And

e) Below 98.85 parts by weight of water is preferred.

[Action]

Hereinafter, the present invention will be described in detail.

The starch of a) may be wheat starch, potato starch, tapioca starch, corn starch and the like, and wheat flour starch is the most efficient in consideration of economy and adhesion.

The surfactant of b) is used to uniformly and stably disperse the antimicrobial agent and to evenly apply starch without agglomeration, thereby increasing the adhesion of the dopant while reducing the amount of the paste, and is based on 0.05 parts by weight of the total composition. To 0.3 parts by weight is preferred. If it is 0.05 parts by weight or less, the addition dispersion effect is low, and if it is 0.3 parts by weight or more, the compatibility with starch or resin becomes low, which may cause destabilization in adhesion of the prepared pool. Examples of such surfactants include sodium dihexylsulfosuccinate, t-octylphenoxypolyethoxy ethanol, and the like.

The antimicrobial agent of c) provides antibacterial (antifungal) properties to the composition of the present invention, prevents decay of the grass, and provides antibacterial and control effects where grass such as wallpaper is applied. As for content of a fungicide, 0.1-5 weight part is preferable with respect to 100 weight part of whole compositions. When used in an amount less than 0.1 parts by weight, the antibacterial power is low, and when used in an amount of 5 parts by weight or less, the compatibility with the starch or the resin may be low, which may cause destabilization of adhesion of the prepared pool.

Such antimicrobial agents can be used even if they are known in the art, but particularly water-insoluble or difficult to dissolve in water is preferable, for example 2-n-octyl-4-isothiazolin-3-one ( 2-n-octyl-4-isothiazolin -3-one), diodomethyl-p-tolysulfone, 2-4-thiazolyl-benzimidazole (2,3,5,6-tetrachloro-4-methylsulphonyl pyridine), methyl-2-benzimidazole carbamate (methyl-2-benzimidazole, 2,3,5,6-tetrachloro-4-methylsulfonyl pyridine) carbamate), N-trichloromethylthio phtalimide, zinc 2-pyridinethiol-1-oxide, sodium 2-pyridinethiol-1-oxide ( sodium 2-pyridinethiol-1-oxide, and methyl-1-butyl carbamoyl benzimidazole-2-ylcarbamate, which may be used alone or in combination Available Can be.

The emulsion synthetic resin of d) is added to protect the adhesion of starch according to the state of the wallpaper and the like to be applied to the addition of the antibacterial agent to protect the resin component in addition to the sustainability of the antibacterial activity. In particular, it is preferable that the nonvolatile content (105 DEG C, 3 hours dry basis) is at least 40% by weight or more. In addition, the amount to be used is preferably 50 parts by weight or less based on 100 parts by weight of the total composition, and use of 50 parts by weight or more is not preferable in terms of cost and effect.

Examples of such emulsion synthetic resins include vinyl acetate, styrene-butadiene, and acrylic.

In the preparation of the composition of the present invention, it is preferable to mix the surfactant and the antimicrobial agent first with water, and then add and mix the starch and the emulsion synthetic resin. If the order is changed, a lot of bubbles may occur.

In addition, the composition of the present invention may be used by adding other functional additives if necessary.
