Benefits of technology

[0009] The present invention is directed toward solving the above described problems, and an object of the present invention is to provide an insect pest-repellent film or the like to realize a safer repellent technique.

Problems solved by technology

Small insects attracted to light come into a glove through these narrow spaces and die within several hours due to lack of water, or heat, and this causes contamination of the interior of the glove.
However, since there is also a problem regarding release of heat generated inside, a decisive measure has not been proposed yet.
However, since lighting fixtures are used in a living environment including a living room, taking into consideration that it may be absorbed through the expiratory air of humans, an agent with a high vapor pressure cannot be used.

embodiment 1

[0063] As an agent having a contact repellent, among cyclopropane carboxylates, Cyphenothrin (α-cyano-3-phenoxybenzyl chrysanthemate) was selected in consideration of a safety standpoint or the like and used as a repellent ingredient. Using this repellent ingredient, a repellent paint having the following composition was prepared.

[0064] To obtain a repellent effect, 20 to 80 parts by weight of, in this embodiment, 50 parts by weight of Cyphenothrin, and 80 to 20 parts by weight of, in this embodiment, 50 parts by weight of Etofenprox were mixed to obtain a repellent ingredient.

[0065] As a sorbitan fatty acid ester type nonionic surfactant, 10 to 50 parts by weight of, here 50 parts by weight of sorbitan tristearate was added with respect to 100 parts by weight of repellent ingredient.

[0066] As a porous carrier particle of an inorganic oxide, a hydrotalcite compound having a high ability to support a repellent ingredient was used in this embodiment. As the properties of a carrier,...

embodiment 2

[0080] In the composition of a paint similar to Embodiment 1, there was used silica gel (average particle diameter: 1 μm) (trade name: SYLOPHOBIC 200) as a porous carrier particle of an inorganic oxide, the surface of which was subjected to a hydrophobic treatment. In respect of this paint also, an evaluation test was carried out in the same manner as in Embodiment 1 to confirm a repellent capability.

embodiment 3

[0081] As an agent having a contact repellent, 50 parts by weight of Cyphenothrin and 50 parts by weight of Etofenprox were mixed to prepare a repellent ingredient. To this, 50 parts by weight of sorbitan tristearate was added with respect to 100 parts by weight of the repellent ingredient.

[0082] As a porous carrier particle of an inorganic oxide, 50 parts by weight of carrier that is a hydrotalcite compound was fully mixed, dispersed and used with respect to 100 parts by weight of repellent ingredient.

[0083] To these ingredients, there was added a solvent having toluene as a main ingredient, which has a mutual solubility with a glove substrate that is an acryl binder, so that a paint was prepared to have a viscosity capable of being applied with a spray.

[0084] This paint was applied with a spray to a connection part between a glove and a lighting fixture body, and the repellent rate was evaluated by comparing with an untreated sample.

[0085] As a result, a practical repellent ca...

Abstract

Insects come into lighting fixtures, and enormous efforts are expended to clean the interior of an enclosure. There is provided a repellent paint, which prevents this and has a prolonged repellent effect. The repellent paint is characterized in that it has at least cyclopropane carboxylate as a repellent ingredient, and comprises at least a porous carrier particle of an inorganic oxide, a surfactant, a paint binder and a solvent.

Description

TECHNICAL FIELD [0001] The present invention relates to an insect pest-repellent film, an insect pest-repellent paint, which are directed toward preventing flying insects such as midges or planthoppers and are applied for lighting fixtures or the like, and improvement of a method for producing the same. BACKGROUND ART [0002] Conventionally, many insects have been attracted to lighting fixtures, and many contrivances have been provided as measures against this. In the case of an incandescent light, since the surface temperature of an envelope thereof is high and this light contains very little ultraviolet light, it attracts fewer insects when compared with a fluorescent light. [0003] On the other hand, with lighting fixture, to enhance a decorative effect or to protect a luminescent part from moisture or dusts, a type in which a luminescent part is not exposed but covered with a glove is broadly used. In this type of lighting fixture also, there are small holes or gaps between a glov...
