Abstract

PURPOSE:To obtain a thickened oil agent for insecticidal and antiseptic use having improved hygienicity and safety in scattering work, by adding a specific amount of a polyisobutylene having a specific molecular weight to an aromatic or aliphatic hydrocarbon solvent or their mixture. CONSTITUTION:An aromatic or aliphatic hydrocarbon solvent (e.g. benzene, kerosine, etc.) or their mixture is added with 1-5wt% polyisobutylene having a molecular weight of 10,000-100,000 to obtain the objective thickened oil agent. Since polyisobutylene can be easily and directly dissolved in the above solvent to increase the viscosity of the solvent, it can be sprayed under pressure in the form of coarse droplets without forming fine mist. Accordingly, it can be used as an insecticidal and antiseptic oil agent in excellent hygienicity and safety.

(Prior art) In general, many of the insect repellent or preservative oils contained in the insect repellent or preservative have a strong mFJ, and are sprayed under pressure to treat the soil under the floor of a house or to treat wood. When spraying, due to its low viscosity, it may diffuse into the air under the floor space, emitting odors, or be inhaled by spraying workers, resulting in hygiene and safety problems during spraying work.

For this reason, it may be possible to increase the specific gravity or thicken the oil, but in the case of insect repellent or antiseptic oils, most of the solvents are hydrocarbon-based from the viewpoint of economy and safety. It uses a solvent, and it is not a thickener that can thicken the oil by directly dissolving in this hydrocarbon solvent. It is known that hydrogen, polybutylene, polyisobutylene, etc. are more soluble in the above-mentioned oil-based hydrocarbon solvents than in water; was not reached.

(Effects of the Invention) According to the thickening oil agent of the present invention, in order to thicken the oil agent, polyisobutylene having a molecular weight of from ioooo to 100,000 is added in an amount of 1% to 5% by weight based on the oil agent. If the content is set within the above range, it will dissolve well directly in the hydrocarbon solvent that makes up the majority of the oil, increase its viscosity, and when the oil is sprayed under pressure, it will not become a fine mist but a coarse liquid. It forms droplets, making it difficult to diffuse into the air in the work space, and also maintains pressurized dispersion and fabric properties.
