Description

  The present invention relates to a spray product for a quick-drying air conditioner that sprays on fins provided in an air conditioner.

In recent years, spray products for air conditioners that can be easily used have been developed to remove dirt and bad odors from home air conditioners (see, for example, Patent Document 1).
However, in conventional products, since aerosols (compositions to be sprayed) contain water, surfactants, and the like, aerosols sag and rebound when sprayed onto fins provided in air conditioners. In addition, there was a problem that the aerosol agent adhered to the floor surface, wall surface, and user. Moreover, a certain amount of time was required for drying on the sprayed treated surface, and there was room for improvement.
JP 11-92795 A

  The present invention provides a spray product for a quick-drying air conditioner that is less dripping or splashing of an aerosol agent when sprayed onto fins provided in an air conditioner, has excellent cleaning power, and is quick to dry on the processing surface. It is for the purpose.

As a result of intensive studies to achieve the above object, the present inventors have found that the object can be achieved by the following and have reached the present invention.

2) The quick-drying air-conditioner fin spray product according to 1) above, wherein the alcohol is ethanol, and the propellant is at least one selected from liquefied petroleum gas and dimethyl ether.
3) Water and a surfactant comprising at least one alcohol selected from ethanol and isopropyl alcohol, a propellant, and at least one selected from a deodorant, an antibacterial agent, an antifungal agent and a fragrance. a aerosol containing no alcohol / propellant 30 / 140-50 / 120, wherein the quick drying air-spray fin products you that filled with aerosols is (volume ratio during liquefaction).
4) A method for cleaning fins of an air conditioner, comprising at least one alcohol selected from ethanol and isopropyl alcohol and a propellant, wherein the alcohol / propellant (volume ratio at the time of liquefaction) is 30 / 140-50. A method for cleaning an air conditioner fin, wherein an aerosol agent / 120 is sprayed onto the fin of an air conditioner.
5) A method for cleaning fins of an air conditioner, comprising at least one alcohol selected from ethanol and isopropyl alcohol, a propellant, a deodorant, an antibacterial agent, an antifungal agent, and an aromatic. It is composed of one type, and does not contain water and surfactants, and the alcohol / propellant (volume ratio at the time of liquefaction) is 30/140 to 50/120. A method for cleaning air-conditioning fins.

  The spray product for an air conditioner of the present invention can suppress dripping or splashing of the aerosol agent when sprayed on the fins provided in the air conditioner.

[Example]
Test example 1
Preparation of test spray product An aerosol container composed of the components shown in Table 1 was filled into an aerosol container equipped with the same injection device as in Example 1, adjusted to an internal pressure of 0.39 MPa, and Examples 6 to 8 and Comparative Examples 1 and 2 were produced. The propellant was LPG / DME = 82.4 / 17.6 (mass ratio). As a reference example, a conventional product (“air-conditioner cleaning spray” manufactured by Earth Pharmaceutical) was used for the test.
The conventional product is an air conditioner spray product consisting of 292.7 mL of a stock solution consisting of an aqueous solution containing 0.1% of a higher alkylamine surfactant and 127.3 mL of liquefied petroleum gas, with an injection force of 127 mN / 5 cm and an injection amount. 120 g / 30 seconds.
1) Liquid sag and rebound test The tests were advanced in the order of the following (1) to (3).
(1) Lay the thermal paper 1m below the air conditioner (SANYO).
(2) Expose the cooling fins of the air conditioner and inject 170 mL of the sample evenly. The injection conditions are: injection amount: 42 g / 30 seconds, injection force: 147 mN / 5 cm.
(3) The number of black spots formed by reaction with the aerosol is counted for each size. The count is classified as follows, imitating black spots as circles.
A: Diameter 3 mm or more and less than 5 mm B: Diameter 5 mm or more and less than 10 mm C: Diameter 10 mm or more The results are shown in Table 1. In Examples 6 to 8, liquid dripping was hardly observed.
2) Cleaning test The test was advanced in the order of the following (1) to (3).
(1) An incense stick is attached to a 7.5 cm × 7.5 cm aluminum plate (the mass of the aluminum plate was measured in advance).
(2) The specimen is sprayed in a vertical direction on an aluminum plate surface fixed at 90 degrees with respect to the ground intermittently for 5 seconds × 6 times (30 seconds). The injection conditions are the same as in test 1).
(3) Measure the mass of the aluminum plate after drying.
The cleaning rate (%) was obtained from the following formula.
Washing rate (%) = 100 × (mass after adhesion-mass after washing) / (mass after adhesion-mass before adhesion)
The above test was performed twice, the average was calculated, and the results are shown in Table 1.
3) Quick-drying test 5 g of the spray product of Example 7 and the reference example (conventional product) were sprayed from a distance of 15 cm onto a 15 cm × 15 cm plastic decorative board, and the drying time was measured. The plastic decorative board was placed horizontally with the ground, and the test conditions were room temperature: 22 ° C. and RH: 35%.
The above test was performed twice, the average was calculated, and the results are shown in Table 1.

From Table 1, in Examples 6 to 8 of the present invention filled with an aerosol agent having an alcohol / propellant (volume ratio) of 30/140 to 50/120, no liquid dripping was observed, and there was almost no rebound. And it turns out that it has a high cleaning effect.
On the other hand, in a reference example (conventional product) containing a stock solution composed of an aqueous solution containing a surfactant, liquid sag was observed and the rebound was apt to be large. In the spray product of the present invention, dripping and rebound are remarkably suppressed, but the cleaning effect is equivalent to that of the reference example although it does not contain a surfactant or water. Moreover, the spray product of the present invention dries the treated surface in about 135 seconds after spraying, whereas in the reference example, wetting was confirmed even after 30 minutes. It turns out that it is excellent in quick-drying.

Test example 2
As a result of performing the same test as in Test Example 1 using Examples 1 to 5, the same effects as in Examples 6 to 8 were obtained. Furthermore, it can be expected that the deodorant and the antibacterial effect become more remarkable by blending the deodorant and the antibacterial agent.
