Embodiment approach 1

[0063]In this embodiment, a description will be given of a case where a pest repellent paint is prepared using an extract of whole wintergreen of the family Wintergreen. Firstly, the whole plant of Wintergreen of the family Wintergreen is fully dried for extraction. The whole plant of Wintergreen of the family Wintergreen is immersed in a mixed solvent of acetone and water (acetone: water = 70 weight units: 30 weight units) for 48 hours. Using a rotary evaporator, the components contained in the substance soluble in the mixed solvent of acetone and water were concentrated. The obtained extract is a dark brown highly viscous viscous substance.

[0064] As the extraction method, general methods can be used, for example, a method of immersing raw plant parts in a mixed solvent for a long time, heating and stirring at a temperature below the boiling point of the mixed solvent for extraction, and a method of obtaining an extract by filtration, etc. In the present embodiment, extr...

Embodiment approach 2

[0092] In this embodiment, the case where the pest repellent paint is prepared using the extract of the whole nasturtium plant of Nasturtaceae family will be described. Firstly, the whole nasturtium plant of Nasturtium family is fully dried for extraction. The whole nasturtium plant of Nasturtaceae family is immersed in a mixed solvent of acetone and water (acetone: water = 70 weight units: 30 weight units) for 48 hours. Using the spray drying method, the components that are soluble in a mixed solvent of acetone and water are concentrated. The obtained extract is a thick tea-brown high-viscosity viscous substance.

[0093] As the extraction method, general methods can be used, for example, a method of immersing raw plant parts in a mixed solvent for a long time, heating and stirring at a temperature below the boiling point of the mixed solvent to extract, and filtering to obtain an extract, etc. . In this embodiment, the extraction with a mixed solvent of acetone and water ...

Embodiment approach 3

[0104] In this embodiment, the case where the insect repellent paint is prepared using the extract of the branches and leaves of the Eucalyptus plant of the family Carpetaceae will be described. Firstly, the branches and leaves of Eucalyptus eucalyptus plant in the family Xylocarpa are fully dried for extraction. Put the branches and leaves of Eucalyptus eucalyptus plant in the acetone and water mixed solvent (acetone: water = 70 weight units: 30 weight units) to immerse for 48 hours. Using the spray drying method, the components that are soluble in a mixed solvent of acetone and water are concentrated. The extract was obtained as an ivory-colored powdery substance.

[0105] In the same manner as in Embodiment 1, a pest repellent paint was prepared, and the repellent performance relative to the coating concentration of the extract was measured. As a result, this extract, at 100mg / 100cm 2 The above application amount shows the pest repelling performance to German cockroaches...

Abstract

A pest repellent paint contains at least one extract selected from the group consisting of an extract of a whole plant which belongs to a wintergreen family (Pyrolaceae), an extract of a whole plant which belongs to a nasturtium family (Tropaaeolaceae), an extract of branches and leaves of a plant which belongs to a myrtle family (Myrtaceae), and an extract of a whole plant which belongs to a primrose family (Primulaceae); at least one paint resin selected from the group consisting of polyvinyl alcohol, carboxymethylcellulose, epoxy resin, urethane resin, and polyester resin; and a paint solvent.

Description

technical field [0001] The present invention relates to a pest-repelling paint and its industrial products, in particular to a pest-repelling paint that prevents sanitary pests, household pests, and unpleasant pests from nesting in the living environment. Also, there is an effective pest repellent paint for improving sanitation that causes pests to build nests, improving habitability of living environments, preventing deterioration of building materials, and preventing allergies of occupants caused by dead insects. Furthermore, it relates to an industrial product printed or coated with the pest repellent paint of the present invention. Background technique [0002] If there are a large number of pests such as cockroaches to build nests on the materials around us such as the devices used in the living environment, the articles displayed, the materials of buildings, etc., it will cause unhygienic or uncomfortable feelings. Also, sanitation is lowered due to feces excreted by ...
