Description

The present invention is a new cleaning for use in cleaning various vehicles, vehicles, transportation facilities such as automobiles, two-wheeled vehicles, bicycles, construction machines, agricultural machinery, aircraft, railroad vehicles, ships, and cleaning tools, workshops, pits, and factories. Regarding the agent composition and its aerosol composition, in particular, various vehicle parts and control devices such as bodies, brake parts, suspensions, wheels, etc. made of metal or a combination of metal and resin in various vehicles, vehicles, and transportation facilities. A cleaning agent that is used in large quantities because it is for degreasing and cleaning, is nonflammable, has a low risk of ignition and fire, and is a non-hazardous material under the Fire Service Law. There are no legal restrictions on the amount of composition that can be stored, and it has excellent properties such as low toxicity and low environmental load such as ozone layer destruction. Furthermore, it is equal to or better than conventional cleaning agent compositions. While having detergency and stain reattachment prevention properties, it has extremely low attack resistance to rubber and resin compared to conventional cleaning agent compositions, and is blended so as to have a desired drying rate according to the usage situation. The present invention relates to a cleaning agent composition and an aerosol composition thereof, which also has an excellent property that the ratio is adjustable.

Various vehicles, vehicles, and transportation such as automobiles, motorcycles, bicycles, construction machinery, agricultural machinery, aircraft, railroad vehicles, and ships have various parts and devices such as bodies, brakes, suspensions, and wheels made of metal and various resins. It is manufactured using such as. Further, in recent years, a member using a composite material in which a resin is combined with a metal has been used for the purpose of reducing the weight and enhancing the decorativeness.

Parts and devices using these metals have oil and dirt adhering to their surfaces during use, and their intended performance and decorativeness deteriorate. In addition, the metal surface is corroded depending on the adhered components, and the desired performance is irreversibly impaired. Furthermore, oil such as grease is applied to necessary parts of vehicles, vehicles, and transportation so that the movement of each device is smooth, but these oils are sprayed with air flow or rainwater during running. As a result, the oil gradually flows out to unintended parts, and the oil that has flowed out from other vehicles, vehicles, and transportation means is rolled up from the road surface together with dirt, and adheres to each part of the vehicle, vehicle, and transportation. , It becomes a factor to deteriorate the expected performance of various parts and devices. In particular, in a friction braking device in which a brake shoe with a brake lining, which is often used in vehicles, vehicles, and transportation, acts as a brake on a rotating body such as a brake disc or a brake drum, the friction coefficient decreases when oil adheres. In addition, dust generated by the wear of the brake lining tends to adhere, which causes the braking performance of the brake to deteriorate. Therefore, perform regular maintenance work to remove oil and dirt from metal parts. There is a need to clean.

In addition, when assembling and manufacturing various vehicles, vehicles, and transportation facilities, when resin or paint is applied to metal and processed, if a small amount of oil or the like remains on the metal surface, the resin or paint will adhere. The quality of the product deteriorates significantly due to peeling or deterioration without stable adhesion. In addition, for parts and devices that are particularly important for ensuring safety during operation, such as brakes, suspensions, and wheels, the friction coefficient will decrease if a small amount of oil is attached, and braking performance will be improved if assembled as is. It will be impaired, and it will not be possible to stably demonstrate the desired performance. Therefore, at the time of assembling and manufacturing vehicles, vehicles, and transportation means, it is required to sufficiently wash and remove the oil slightly adhering to the metal surface of each part in advance.

Therefore, as a cleaning agent composition mainly for cleaning the bodies, brake parts, suspensions, wheels, etc. of various vehicles, vehicles, and transportation facilities, conventionally, one containing trichloroethane having a cleaning property as a main component has been developed and used. It had been. However, trichloroethane is known to be toxic. In addition, trichloroethane is the Montreal Protocol on Ozone-Depleting Substances, which came into effect under the Vienna Convention for the Protection of the Ozone Layer, which will gradually reduce production and consumption in Parties and abolish it in 1996. Imports and exports with non-parties will be banned or restricted. Therefore, the use of a cleaning composition using trichloroethane has been avoided.

Therefore, based on C6 petroleum hydrocarbons such as isohexane and cyclohexane, alcohols such as ethanol and isopropyl alcohol are added to produce a cleaning agent composition having adjusted detergency, drying property, and boiling point, which is used as LPG. Aerosol compositions using gas and aerosol compositions using compressed air using a mobile simple aerosol filling machine have been proposed and are widely used.

However, petroleum-based hydrocarbons and alcohols used in the above cleaning agent composition are highly flammable and are regulated as dangerous goods under the Fire Service Act. Therefore, it is necessary to set up a dangerous goods warehouse for storage, and the cost for setting up is high. Moreover, even if a facility using a cleaning agent composition has a hazardous material warehouse, the amount that can be stored is limited. In particular, most of the cleaning agent compositions are classified as Class 4 First Petroleum, but the designated quantity of Class 4 First Petroleum that can be stored in one warehouse is set low by law. Although the amount of the cleaning agent composition used is large, there is a problem that only a small amount can be stored, and improvement thereof has been required.

Furthermore, although the hydrocarbons used in the cleaning composition are not as toxic as trichloroethane, there is a risk of hydrocarbon poisoning by inhaling an excessive amount, so they are used outdoors or indoors with a ventilation system. It is necessary to use it in a well-ventilated environment, and the product also has a note to that effect. However, since aerosol products are used, vaporized hydrocarbons flow not only in the workplace but also on the leeward side, and there is still a risk of inhalation by those who are there, and improvement has been sought.

In addition, if the cleaning agent composition is poured or the aerosol product is vigorously sprayed during the work, a large amount of the highly flammable cleaning agent composition may permeate into the gloves and clothes of the worker. In addition, a large amount of the cleaning agent composition may be impregnated in order to remove oil stains adhering to the gloves and work clothes of the worker. However, since the cleaning agent composition is highly flammable, if the subsequent drying is insufficient, there is a risk of ignition accident due to static electricity or cigarette fire. Therefore, in order to ensure reliable safety in the working environment, improvements have been required to avoid the use of these highly flammable components.

Halogen-based solvents are generally well known as solvents that do not have a flash point, but chlorine-based and bromine-based solvents have restrictions on production and use due to their harmfulness, and can be used in cleaning agent compositions. Is difficult. Therefore, as a proposal to solve the problems of storage volume and ensuring safety, we propose products with high flash points using petroleum-based hydrocarbons with a long carbon number and water-based products containing carbitol, alcohol, etc. as cleaning components. (See Patent Document 1).

However, the above-mentioned aqueous composition has very poor drying property and is slow, for example, it takes 30 to 40 minutes to dry (see Patent Document 1). Therefore, when these water-based compositions are used as a cleaning agent composition, the liquid of the water-based composition tends to remain around the brake after use, and if the brake is used with the liquid remaining, the braking force of the brake is reduced. It leads to a serious impact. Therefore, the work process using the above-mentioned aqueous composition is complicated because it is indispensable to sufficiently dry it after washing, and improvement is required. Furthermore, since it is water-based, it is inferior in cleaning performance to the conventional cleaning agent composition for brake cleaners, and depending on the type of dirt, it does not necessarily have sufficient cleaning performance, so there are restrictions on the usage situation. , Improvement was required so that it would be more versatile.

By the way, as a solvent that can be used for cleaning metal materials, an HFO-based nonflammable fluorine-based solvent that is a hydrofluoroolefin-based solvent such as (Z) -1-chloro-3,3,3-trifluoropropene It has been known. However, although this HFO-based nonflammable fluorosolvent has detergency against metal materials, it is known to have strong erosion properties against resins and elastomers that are materials other than metal materials. (Non-Patent Document 1). Therefore, it is necessary to thoroughly examine the situation in which such an HFO-based nonflammable fluorine-based solvent is used.

In particular, it is important to maintain high safety of various braking devices, lights, windows, etc. in various vehicles, vehicles, and transportation such as automobiles, motorcycles, bicycles, construction machinery, agricultural machinery, aircraft, railroad vehicles, and ships. Metallic materials are widely used for parts, but in addition to these metal materials, various types such as polycarbonate, acrylic, ABS, polystyrene, silicone rubber, natural rubber, HNBR, NBR, fluororubber and urethane rubber are usually used. Materials made of resin and elastomer are also used at the same time. For example, the brake is controlled by the hydraulic pressure of the brake fluid, which is generally filled in a rubber hose connecting the devices.

However, when the above-mentioned HFO-based nonflammable fluorine-based solvent comes into contact with the resin or elastomer, it is an important component that is required to maintain high safety due to the strong erosion property of the above-mentioned HFO-based nonflammable fluorine-based solvent. Serious problems such as deterioration of the resin and elastomer in the above occur. In particular, polycarbonate, which is widely used in important parts of vehicles, vehicles, and transportation, is devitrified, acrylic, ABS, and polystyrene are dissolved, and silicone rubber, natural rubber, HNBR, NBR, fluorine rubber, and urethane rubber are swollen. (Non-Patent Document 1), there is a concern that the safety may be reduced.

Further, when it is used as a cleaning composition, it is necessary to sufficiently moisten the portion to be cleaned with the cleaning composition and wash it away. However, since the above-mentioned HFO-based nonflammable fluorine-based solvent has a low boiling point. It is very dry and is not suitable for the process of moistening and rinsing. When moistened, there is a concern that an excessive amount of HFO-based nonflammable fluorine-based solvent may reduce safety by coming into contact with resins and elastomers in important parts.

As the fluorine-based solvent, methoxyperfluoroheptene, which is an alkoxyfluoroalkene, and Opteon ^TM SF10 (former name: Bartrel (registered trademark) Suprion), which is a mixture thereof, (Mitsui DuPont Fluorochemical Co., Ltd.) There is. This Optheon ^TM SF10 is suitably used as a lubricant solvent using fluorine grease (Patent Document 2), but brakes in various vehicles such as automobiles, motorcycles, construction machinery, agricultural machinery, aircraft, railroad vehicles, and railroad vehicles. By creating a situation in which these lubricating components are applied and coated on related parts, the friction coefficient is not reduced and the braking force is not significantly reduced.

It is an object of the present invention to provide a new cleaning agent composition and an aerosol composition thereof, which have a drying property but have an extremely low attack property on rubber and resin as compared with a conventional cleaning agent composition.

Since the cleaning agent composition is used for the work of moistening and washing off the dirt components, the amount used and the amount stored are large. Therefore, it is required to greatly reduce the risk of fire due to ignition by selecting a solvent that does not have a flash point and does not have a combustion range under the temperature conditions of a normal use environment and a storage environment.

Further, in cleaning, it is required to moisten the stain component with a cleaning agent composition and wash it off.

The cleaning agent composition of the means of the present invention and its aerosol composition shall contain two components, an HFO-based nonflammable fluorine-based solvent and an alkoxyfluoroalkene.

Since the above-mentioned HFO-based nonflammable fluorine-based solvent causes deterioration, devitrification, or dissolution of the resin and the elastomer (Non-Patent Document 1), it is not possible to use the resin and the elastomer as they are as a component of the cleaning agent. Not preferred. Further, the alkoxyfluoroalkene is suitably used as a solvent for a lubricant using fluorine grease (Patent Document 2), and brakes in various vehicles such as automobiles, motorcycles, construction machinery, agricultural machinery, aircraft, railroad vehicles, and railroad vehicles. It is possible to avoid creating a situation where these lubricating components are applied / coated in related parts.

However, it is expected that an HFO-based nonflammable fluorine-based solvent, which is unsuitable as a component to be blended in such a cleaning agent composition, is contained together with an alkoxyfluoroalkene which is preferably used as a solvent for a lubricant. In addition, it does not cause any effects such as alteration, devitrification, and dissolution on resins and elastomers, has a wider range of excellent cleaning properties than conventional cleaning agent compositions, and has appropriate drying properties.

Therefore, by incorporating both an HFO-based nonflammable fluorine-based solvent and an alkoxyfluoroalkene as main components, it is possible to use it for a wider variety of materials while maintaining various safety. It has become possible to provide a new cleaning agent composition and an aerosol composition thereof having the above-mentioned characteristics.

<About HFO-based nonflammable fluorine-based solvents>
The cleaning agent composition of the means of the present invention and its aerosol composition described above contain an HFO-based nonflammable fluorine-based solvent which is a hydrofluoroolefin-based solvent as one of the two essential components. It shall be. Examples of the HFO-based nonflammable fluorine-based solvent include (Z) -1-chloro-3,3,3-trifluoropropene, 1,1-dichloro-3,3,3-trifluoropropene, and 1,2-dichloro. Non-flammable solvents such as -3,3,3-trifluoropropene, 2,3,3-trichloro-3-fluoropropene and AMOLEA® AS-300 can be used. These HFO-based nonflammable fluorine-based solvents can be used by obtaining commercially available ones ((Z) -1-chloro-3,3,3-trifluoropropene (1233Z) (Central). Glass Co., Ltd., Japan), 1,1-dichloro-3,3,3-trifluoropropene (Matrix Scientific, USA), AMOLEA (registered trademark) AS-300 (AGC Co., Ltd., Japan), etc.).

The above-mentioned HFO-based nonflammable fluorine-based solvent is a nonflammable solvent having no flash point and no combustion range according to the explosion limit test method ASTM E681. In addition, it has environmentally friendly chemical properties such as a low ozone depletion potential ODP or substantially zero global warming potential GWP <1. Therefore, it does not fall under the components specified by the Ozone Layer Protection Law, Global Warming Countermeasures Promotion Law, Freon Emission Control Law, Fire Service Law, High Pressure Gas Safety Law, etc., and its use is not subject to any special restrictions. There is no need for a dangerous goods warehouse for storage, and there are no legal restrictions on the amount of storage.

On the other hand, the above-mentioned HFO-based nonflammable fluorine-based solvent has invasiveness to the resin.

When it acts on a polyvinyl chloride (PVC) resin or a phenol resin, the resin is altered, and the weight and dimensions of the resin product are changed. Further, when it acts on the polycarbonate resin, the resin is whitened and devitrified. Further, when it acts on an acrylic (PMMA) resin, an ABS resin or a polystyrene resin which is a copolymer synthetic resin of acrylonitrile, butadiene and styrene, those resins are softened or dissolved. As described above, the above-mentioned HFO-based nonflammable fluorine-based solvent has poor compatibility with the resin material.

In addition, the above-mentioned HFO-based nonflammable fluorine-based solvent is also invasive to various elastomers. Therefore, HFO-based nonflammable fluorine-based solvents such as (Z) -1-chloro-3,3,3-trifluoropropene and 1,1-dichloro-3,3,3-trifluoropropene are SBR and chloroprene. When it acts on rubber, butyl rubber, EPDM and CSM, these elastomers are altered to change their weight and dimensions. Further, when it acts on silicone rubber, natural rubber, HNBR, NBR, fluororubber and urethane rubber, those elastomers swell. As described above, the HFO-based nonflammable fluorine-based solvent has poor compatibility with the elastomer as it is.

However, various vehicles / vehicles such as automobiles, motorcycles, bicycles, construction machines, agricultural machinery, aircraft, railroad vehicles, and ships, which have poor resin compatibility and high dryness of the above-mentioned HFO-based nonflammable fluorine-based solvent. -Unexpectedly, the properties that are inappropriate for cleaning agent compositions used in transportation facilities, etc. are eliminated by including alkoxyfluoroalkenes that have other properties that are inappropriate for cleaning agent compositions.

CF ₃ (CF ₂ ) CF = CF (CF ₂ ) ₂ (OCH ₃ ) CF ₃
CF ₃ (CF ₂ ) CF = CFCF (OCH ₃ ) CF ₂ CF ₃
CF ₃ CF = CFCF (OCH ₃ ) (CF ₂ ) ₂ CF ₃
CF ₃ CF = CFCF ₂ CF (OCH ₃ ) CF ₂ CF ₃
CF ₃ (CF ₂ ) CF = C (OCH ₃ ) (CF ₂ ) ₂ CF ₃

<Test Example 1: Evaluation of invasiveness (long-term contact)>
-Materials and methods As test solutions, the solutions of Examples 1 to 14 and Comparative Examples 1 to 8 are prepared.
In addition, the following test pieces are prepared to evaluate the invasiveness.
Rubber: NR (natural rubber)
: CR (chloroprene rubber)
: SBR (Styrene-butadiene rubber)
: EPDM (Ethylene Propylene Rubber)
(Both are obtained from Standard Test Piece Co., Ltd., Japan.)
Resin: ABS (Acrylonitrile Butadiene Styrene)
: LDPE (Low Density Polyethylene)
: PC (polycarbonate)
(Both are Japan Test Panel Co., Ltd.)

The weight of each of the above rubber or resin test pieces (size 10 mm x 10 mm x 2 mm) is measured.
Next, 20 mL of the solution of Example or Comparative Example was placed in a vial, and each of the above rubber or resin test pieces (size 10 mm x 10 mm x 2 mm) was immersed therein, and the vial was set at 45 ° C. Place in a constant temperature and humidity machine (HPAV-120-40, Isuzu Motors Ltd., Japan) and let stand.
After taking out each test piece from the vial and observing the surface condition, measure the weight and thickness of the test piece, calculate the degree of swelling, check whether it is within the range of ± 5.0%, and PC. Also check if the transparency of the is not lost.
When the amount of solution used is small, the test is performed with the size of the test piece and the amount of liquid proportional to the amount used.

-Test results The results of the above tests are shown in Tables 1-1 to 1-3.

In Test Example 1, it was found that the composition containing the HFO-based nonflammable fluorine-based solvent and the alkoxyfluoroalkene improved the invasiveness of the HFO-based nonflammable fluorine-based solvent to rubber or resin. confirmed. Then, a comparative verification with a conventional cleaning agent regarding non-invasiveness to rubber or resin was performed.

HFO-based nonflammable fluorine-based solvent is invasive to rubber and resin when acted on for a long period of time, and is especially important for ensuring safety in various vehicles, vehicles, transportation facilities, etc. Swells NR (natural rubber), SBR (styrene-butadiene rubber), EPDM (ethylene propylene rubber), which are widely used in equipment and parts, dissolves and softens ABS (acrylonitrile butadiene styrene), and swells PC (polycarbonate). It showed strong invasiveness such as whitening, devitrification, and cracking, and the degree of deterioration of these rubbers and resins could not guarantee the quality as a product (Table 1-1).

In addition, conventional cleaning agents are flammable in the first place, and when acted on rubbers such as NR, CR, SBR and EPDM, and resins such as ABS, LDPE (low density polyethylene) and PC, they are strongly invasive. Similarly, the quality of the product could not be guaranteed (Table 1-1).

However, by blending an alkoxyfluoroalkene with an HFO-based non-flammable fluorine-based solvent, surprisingly, various rubbers and resins observed when the above-mentioned HFO-based non-flammable fluorine-based solvent was used. It has been clarified that the phenomena of swelling, dissolution, whitening, devitrification, and cracking can be eliminated (Tables 1-2 to 1-3).

It is possible to create a cleaning agent composition with new properties that does not show invasiveness to various rubbers and resins that are widely used in equipment and parts that are important for ensuring the safety of various vehicles, vehicles, and transportation facilities. It is understood that the invention capable of providing a highly effective means of replacing conventional cleaning agents that are invasive. Further, it is understood that the cleaning agent composition of the means of the present invention has very little concern that it may be invasive to rubber or resin even if it is used for a long period of time.

Further, since the amount of HFO-based nonflammable fluorine-based solvent that can be produced is limited, the cleaning agent composition of the means of the present invention is produced by mixing an HFO-based nonflammable fluorine-based solvent and an alkoxyfluoroalkene. Therefore, it is understood that the cleaning agent composition has an effect of increasing the supplyable amount and preventing a stagnation of product supply.

Of the above rubbers, SBR (styrene-butadiene rubber) is also used for sealing the brake fluid system of automobiles and for tires, etc. Therefore, the cleaning agent used for cleaning the brake device and its surroundings is erosive to SBR. Is desired to be low. PC (polycarbonate) is also used in control system mechanisms such as brake devices. However, by blending an alkoxyfluoroalkene with an HFO-based nonflammable fluorine-based solvent as in the present invention, surprisingly, the problem of erosion to SBR and PC is sufficiently reduced, and their swelling is achieved. The rate could be suppressed to 5% or less, which can maintain the quality of the product to a certain extent.

<Test Example 2: Evaluation of invasiveness (short-term contact)>
-Materials and methods Similar to Test Example 1, the solutions of Examples 1 to 14 and Comparative Examples 1 to 8 described above are prepared respectively. In addition, in order to evaluate the invasiveness in a short period of time, the following test pieces are prepared.
Resin: ABS (Acrylonitrile Butadiene Styrene)
: PC (polycarbonate)
(Both are Japan Test Panel Co., Ltd.)

The surface of each test piece of the above resin (size 10 mm x 10 mm x 2 mm is wiped with a microfiber cloth containing the solutions of Examples 1 to 18 or Comparative Examples 1 to 8.) After that, the appearance change of the surface of each test piece is visually observed. If there was no change in appearance, it was marked as ◯, and if there was a change, it was marked as x, and the state of the resin surface was recorded.

-Test results The results of the above tests are shown in Tables 2-1 to 2-3.

The HFO-based nonflammable fluorine-based solvent, which is one of the main components used in the cleaning agent composition of the means of the present invention, can be contacted only for a short time by wiping the surface with a microfiber cloth containing a solution. , The resin composed of ABS and PC is altered (Table 2-1).

However, by blending an alkoxyfluoroalkene with an HFO-based nonflammable fluorine-based solvent to prepare the cleaning agent composition of the means of the present invention, deterioration of the resin occurs due to such short-time contact. It was clarified that it disappeared (Table 2-2 to Table 2-3).

<Test Example 3: Evaluation of compatibility with grease and oil>
-Materials and methods Similar to Test Example 1, the solutions of Examples 1 to 14 and Comparative Examples 1 to 8 are prepared as test solutions.

As the oils and fats to be cleaned and removed, the following various greases and oils commonly used in automobiles and the like are prepared.
Grease: GRASE (Orange) (Kobe Synthetic Co., Ltd., Japan)
: Rubber combined brake grease (Kobe Synthetic Co., Ltd., Japan)
: Grease for disc brakes (Kobe Synthetic Co., Ltd., Japan)
: Brake grease (Kobe Synthetic Co., Ltd., Japan)
: Silicone grease (Kobe Synthetic Co., Ltd., Japan)
: Calipering grease (Honda Access Co., Ltd., Japan)
: Pad & Shoe Grease (Honda Access Co., Ltd., Japan)
: Rubber grease (Honda Access Co., Ltd., Japan)
: Brake grease (Honda Access Co., Ltd., Japan)
Oil: Engine oil Mobile10W-20 (ExxonMobil, USA)
: Brake fluid (DOT3) (Honda Access Co., Ltd., Japan)
: Brake fluid (DOT4) (Suzuki Corporation, Japan)

Prepare a 10 mL vial for each solution and add 1 g of each of the above grease or engine oil. Further, 5 mL of the solution of Example or Comparative Example is added to the vial, and the lid of the vial is closed. Each vial is sonicated with an ultrasonic cleaner (AU16C, Aiwa Medical Industry Co., Ltd., Japan) for 1 hour.
After 1 hour of sonication, remove each vial from the ultrasonic cleaner. Check the inside of the vial, and if the grease or engine oil and the solution of the example or comparative example are completely mixed, mark ○, if partially separated, mark △, if completely separated, mark ×. Evaluate solubility. If the amount of solution used is small, the test is performed with a liquid amount proportional to the amount used.

-Test results The results of the above tests are shown in Tables 3-1 to 3-3.

It was revealed that the alkoxyfluoroalkene used in the above test had almost no compatibility with grease or brake oil (Comparative Example 8 in Table 3-1). From this, it is understood that the alkoxyfluoroalkene is not suitable as a cleaning agent for removing stains caused by oil and fat components such as grease or brake oil. Further, although the HFO-based nonflammable fluorine-based solvent has appropriate compatibility, it has invasiveness to resins and elastomers as is clear from the test results of Test Example 1 and Test Example 2, and therefore, various vehicles, vehicles, and the like. It is not suitable for cleaning composition used in transportation. As described above, various HFO-based nonflammable fluorine-based solvents and alkoxyfluoroalkenes both lack the motivation to be added to the cleaning agent compositions used in various vehicles, vehicles, transportation means, and the like.

However, if the above-mentioned HFO-based nonflammable fluorine-based solvent that cannot be used for cleaning vehicles, vehicles, and transportation facilities and alkoxyfluoroalkene are contained together, it is surprisingly fats and oils such as grease or brake oil. It has been clarified this time that it exhibits a wide range of compatibility with the components, that is, it exhibits high detergency with respect to these oil and fat components (Table 3-2). In addition, the range of the mass ratio of the HFO-based nonflammable fluorine-based solvent and the alkoxyfluoroalkene showing compatibility was also wide (Table 3-2-Table 3-3). Therefore, as in the means of the present invention, by making the cleaning agent composition and its aerosol composition contain an HFO-based nonflammable fluorine-based solvent and an alkoxyfluoroalkene, oils and fats to be cleaned The range of the mass ratio of the HFO-based nonflammable fluorine-based solvent and the alkoxyfluoroalkene is set according to the type of the resin and the type of resin and elastomer used in the cleaning target area and the surrounding area to be deterred from invasion. It is understood that it is possible to provide a cleaning agent composition having properties suitable for the scene in which the cleaning agent composition is used and an aerosol composition thereof.

In addition, conventional cleaning agents may lack compatibility with GRASE (orange) and rubber grease (Table 3-1). However, as shown in Table 3-2, the HFO-based nonflammable fluorine-based solvent is diluted by containing the alkoxyfluoroalkene, which has almost no compatibility with GREASE (orange) and rubber grease. However, it was clarified that new ones showing compatibility with those GRASE (orange) and rubber grease were obtained.

As described above, by containing the HFO-based nonflammable fluorosolvent and the alkoxyfluoroalkene in the cleaning composition as in the present invention, the cleaning composition exhibits a wide range of compatibility with grease or brake oil. It is understood that new cleaning agent compositions can be provided that are nonflammable and low in toxicity, yet have excellent cleaning properties equal to or better than conventional brake cleaners.
<Test Example 4: Evaluation of Dryness in Cleaning Agent Composition>
-Materials and methods Similar to Test Example 1, the solutions of Examples 1, 3, 5, 7, 9 to 14 and Comparative Examples 1 to 5 described above are prepared respectively.

A constant temperature and humidity chamber (HPAV-120-40, Isuzu Seisakusho Co., Ltd., Japan) was set at 45 ° C., 25 ° C. or 10 ° C. under a temperature condition of 70% humidity, and a 2 cm flat plate was placed therein and allowed to stand. When the temperature of the flat plate became constant, 100 μL of the solutions of Examples 1, 3, 5, 7 and 9 and Comparative Examples 1 to 5 was placed in the flat plate, and the droplets of each solution completely volatilized from the flat plate and dried. Visually measure the time until this happens.

-Test results The results of the above tests are shown in Tables 4-1 to 4-3.

For cleaning composition that is required to ensure good workability and safety, the optimum time required for drying is typically 1 to 2 minutes in a high temperature environment of 40 ° C, 25 ° C. It is preferably 2 to 3 minutes in a normal temperature environment and 3 to 4 minutes in a low temperature environment of 10 ° C. With conventional cleaning agents, only the quick-drying stock solution type can achieve such conditions, and the other cleaning agents require an excessive amount of time to dry (Table 4). -1). However, this quick-drying stock solution type has a short time required for drying, but has high flammability, and has a problem from the viewpoint of ensuring the high safety required for the cleaning agent composition.

As was clarified in Test Example 3, the cleaning agent composition of the means of the present invention containing an HFO-based nonflammable fluorine-based solvent and an alkoxyfluoroalkene is a nonflammable cleaning having excellent properties for oil and fat components. It is an agent composition. Therefore, it was examined what kind of drying time the cleaning agent composition containing the HFO-based nonflammable fluorine-based solvent and the alkoxyfluoroalkene could have.

As a result, the HFO-based nonflammable fluorine-based solvent has a short drying time (Table 4-1), and as an example of the alkoxyfluoroalkene contained together, Opteon ^TM SF10 as an isomer mixture of methoxyperfluoroheptene. It was clarified that when the above was used, the drying time was lengthened and a standard working time could be secured (Tables 4-2 and 4-3). It was also confirmed that increasing the blending ratio of the alkoxyfluoroalkene makes it possible to obtain a cleaning agent composition having a longer drying time (Tables 4-2 and 4-3). Adjust the types of HFO-based nonflammable fluorine-based solvent and alkoxyfluoroalkene, and the mass ratio of HFO-based nonflammable fluorine-based solvent to alkoxyfluoroalkene so that the desired drying rate is obtained according to the usage situation. It became clear that it could be done.

By including HFO-based non-flammable fluorine-based solvent and alkoxyfluoroalkene in the cleaning agent composition, it is non-flammable, so the risk of ignition and the risk of fire are low, and it is a non-dangerous substance under the Fire Service Law. There is no legal limit on the amount of cleaning agent composition that can be used in large quantities, there is no need for a hazardous material warehouse, the toxicity is low, and the environmental load such as ozone layer depletion is small. While having a cleaning property equal to or higher than that of a cleaning agent composition for a brake cleaner, it is provided with an excellent property that it has an extremely low attack property on rubber and resin, and has a desired drying rate according to the usage situation. In addition, it becomes possible to provide a new cleaning agent composition and an aerosol composition thereof in which the mass ratio of the HFO-based nonflammable fluorine-based solvent and the alkoxyfluoroalkene is adjusted.
