Inorganic insect repellent composition and preparation method

The present invention prevents the damage caused by pests and molds when storing fabrics and clothes for a long time in the home and clothing manufacturing and retail stores as well as the antifungal mold having a use mark function to indicate the replacement time of the insect repellent It relates to an insect repellent composition and a manufacturing method.

Conventionally, the insect repellent composition which solidified naphthalene, paradichlorbenzene, etc. in the form was manufactured. Such insect repellents have a selective effect only on pests such as assorted worms, assorted worms, wormwood moths and small wormwood moths, and there is a problem in that they cannot remove molds generated in fabrics and clothes due to long-term storage. In addition, it is difficult to identify the completion time of use of the insect repellent, and often the case that clothing and fabrics are damaged by not replacing the insect repellent at the appropriate time. Furthermore, in order to solve such a problem, an economic loss is obtained by replacing the insect repellent in the middle without using it completely.

Therefore, there has been a continuous need for the development of new insect repellents capable of simultaneously removing pests and mold and knowing when to replace them.

Therefore, the present invention has been made to solve the above problems, and to meet the needs of the general consumer, to be able to remove the pests and fungi at the same time, and to display the time of completion of use of the insect repellent display function It is an object of the present invention to provide an insect repellent composition for removing pests and molds and a method for producing the same.

The present invention to achieve the above object

i) insect repellent mixture vaporized at room temperature;

ii) oil-permeable intrinsic color which gradually volatilizes the insect repellent mixture

iii) to provide a fungicide combined use insect repellent composition having a display function of use, characterized in that the coating material is applied to the holding material consisting of a permeability, a low refractive index chromophore visually identified.

In the present invention, the insect repellent is a mixture of 70-99.9% by weight of Empenthrin (Empenthrin) and 0.01-0.1% by weight of dimethylphthalate, which is a mixture vaporized at room temperature.

The insect repellent may be prepared by adding a mold inhibitor α-bromocinnamaldehyde (α-Bromocinnamaldehyde) to be mixed to remove pests and mold at the same time.

The insect repellent and antifungal agent are stirred for 30 minutes at 100 RPM in a mixer.

The retaining material is made of permeable natural and synthetic fibers, paper, pulp, nonwoven fabric or inorganic fiber, which do not chemically bond to the insect repellent mixture (mixing of the insect repellent and the fungicide) and gradually volatilizes the insect repellent. Keep chemically stable.

The chromophore was added to 30 to 60% by weight of water, 5 to 40% by weight of amorphous silica, 10 to 40% by weight of vinyl acetate binder, 0.02 to 10% by weight of epoxy resin, and 0.1 to 2% by weight of silicate, and then 8,000 to It is to provide a method for manufacturing by mixing by stirring at 12,000RPM or more for 4 hours.

Hereinafter, the present invention will be described in detail.

In the present invention, the white colorant of a chromophore (a mixture of a coloring agent, a crosslinking agent, and an adhesive) is applicable to inorganic materials such as amorphous silica, kaolin, calcium carbonate, zeolite, calcium silicate and alumina silicate, and organic materials such as pulp powder. Can be.

The bond strength as well as the degree of permeability may vary depending on the type, the mixing ratio, and the amount of the adhesive used to bond the chromosome to the holding material.

In this case, acrylic, vinyl acetate, polyvinylalcohol (PVA), ethylene vinylacetate (EVA), styrene-butadiene rubber (SBR), casein (casein), and starch may be used as the binder.

In addition, in order to improve the bonding strength with the holding material, it is preferable to apply a crosslinking agent such as melamine, urea and epoxy resin, and a pH adjusting agent such as ammonia water, phosphate and silicate.

In addition, the colorant of the chromophore may vary in the degree of permeability depending on the particle size, specific surface area, internal surface area, content and refractive index, so the particle size is 2.0-20 μm, specific surface area 150-300 m ² / g, internal surface area 150- 350m ² / g, the content of DOP (Dioctyl Phthalate) absorption standard 100 ~ 500cc / 100g, the refractive index is the range of 1.43 ~ 1.48 is most suitable.

As the holding material, natural fiber, synthetic fiber, paper, pulp, nonwoven fabric and inorganic fiber are applied.

The retaining material should be chemically stable against the insect repellent mixture, and should not be chemically bonded, and its content should be 100 to 500 cc / 100 g based on DOP absorption.

In addition, during use, the insecticide mixture should be of a physical property that slowly migrates to the chromosome.

The retaining material and the chromophore initially exhibit an intrinsic color, but when the insecticide mixture contained in the retaining material penetrates into the chromophore, it becomes transparent due to the low refractive index of the insect repellent. Afterwards, when the insecticide mixture contained in the retaining material is completely vaporized, the chromophore becomes opaque again, and the original color appears.

Therefore, the color tone of the chromosome on a holding material is changed by volatilization of an insect repellent mixture, and the completion time of use of an insect repellent mixture is displayed. In addition, when the chromophore which is three kinds of mixtures of a binder, a crosslinking agent, and a coloring agent is excessively applied to the holding material, the color of the chromophore becomes unclear. In addition, when excessively applied, the change of color is accelerated, and the function of indicating completion of use according to the presence or absence of the insecticide mixture is not sufficiently exhibited. Therefore, the coating amount of the chromophor is suitably 0.1 to 10 g (dry state) per m ^{2 of the holding} material.

The amount of the adhesive to the chromosome is suitably 10 to 40% by weight, and the ratio of the colorant and the adhesive is 1: 0.6 to 2.0 (weight ratio). As for the ratio of an adhesive agent and a crosslinking agent, the range of 1: 0.01-1 (weight ratio) is the most suitable. The pH of the adhesive mixture is most suitably between 7.5 and 9.5.

As described above, in the present invention, when the insect repellent mixture is contained in the retaining material, the color change of the chromophore is accurately indicated when the use of the insect repellent mixture is completed. In addition, the retaining material and the colorant are preferably selected as complementary colors in order to accurately display the time of use completion. For example, white and black, red and blue, black and yellow.

The method of apply | coating and inject | pouring a chromophore and an insect repellent mixture which are three types of mixtures of a binder, a crosslinking agent, and a coloring material to a holding material is demonstrated.

The chromophore mixture can be applied by any method such as silk screen, gravure and offset printing. However, the coating amount is suitably 0.1 to 10 g (dry state) per m ^{2 of the holding} material as described above. The method of injecting the insect repellent mixture may be applied by an immersion method in which the retaining material coated with the chromosome mixture is impregnated into the insect repellent mixture and an injection method in which the insect repellent mixture is directly injected into the retaining material. In addition, any one of the above deposition method and injection method can be applied to the production, but it is preferable to adjust the composition ratio of the insect repellent mixture according to the injection method so that the insect repellent mixture evenly dispersed in the holding material.

When the deposition method is applied, the mixing ratio of the insect repellent mixture, the inorganic solvent and the organic solvent is most suitably 1: 0.01 to 0.1: 0.5 to 5 (weight ratio). In addition, the organic solvent allows the insect repellent mixture to diffuse and penetrate into the holding material quickly, and must be volatilized immediately, so that volatile (hexane), acetone, ethyl alcohol, ethyl alcohol, methyl alcohol and ether have good volatility. It is preferable to apply (Ether) or the like.

Insect repellent mixture contained in the retaining material should be chemically stable, and the opposite side of the chromosome should be applied with a barrier to block the flow of air in order to allow it to move slowly to the chromosome during the service period. Barriers should be non-air permeable and not dissolved by the insecticide mixture or solvent. In addition, it should be a material with good adhesion to the holding material. As the barrier material having the above characteristics, polyethylene, polypropylene, polyester, polyvinyl chloride, or the like may be applied.

Insect repellents are added with a mold remover to protect the fabric or clothing from pests and mold. The mold remover is good compatibility with the insect repellent, and should be applied to the medium pressure and the holding material is about the same, the material excellent in the fungal function. As a substance having such a property, α-Bromocinnamalde-hydle, ethoxyphenol, P-chloro-3,5-xylenol, etc. Apply. The mixing ratio of the insect repellent and the mildew is preferably 1: 0.001 to 0.1 (weight ratio).
