This black film forms a plurality of layered structures in which carbon contained in brown sugar spreads two-dimensionally, and alkali metals such as calcium, potassium, magnesium, etc. contained in brown sugar and molasses mentioned above between the layers. It is presumed to be composed of a graphite intercalation compound interspersed with alkaline earth metal.
In addition, the above heat resistance cannot be obtained with white sugar or honey.

次に、水ガラスは、硼砂を混入すると硬化するものの、さらに適量の黒砂糖を混合した場合には、適度の粘性を備えて液状組成物となる。そして、この液状組成物は、割り箸の先に塗布して、約８００℃の電熱ヒーターに近づけると、煙を放出するとともに気泡を形成しながら直径３ｃｍ程に膨張して、表面堅さを備えた膨張黒色被膜を形成する（加熱膨張性）。   Next, although water glass hardens when borax is mixed, when an appropriate amount of brown sugar is further mixed, it becomes a liquid composition with an appropriate viscosity. And when this liquid composition was applied to the tip of the disposable chopsticks and brought close to an electric heater at about 800 ° C., it released a smoke and expanded to a diameter of about 3 cm while forming bubbles to provide surface hardness. An expanded black film is formed (heat expandability).

本発明の液状組成物、およびこの液状組成物を塗料に配合した塗料組成物は、上述の適度の粘性、表面堅さおよび加熱膨張性により、被塗布物や塗料組成物に耐熱性・防炎性を付与するものと推認される。
特に、本発明の液状組成物、および液状組成物１００質量部に塗料５〜１０質量部を配合した塗料組成物は、同様に上述の粘性、表面堅さおよび加熱膨張性により、被塗布物に灰化形状を保持する灰化形状保持性能を付与するものと推認される。
さらに、上述の液状組成物５〜６０質量部を二液型エポキシ系樹脂塗料１００質量部に配合した塗料組成物は、上述の膨張過程において厚膜の独立発泡塗膜が形成されることにより、断熱性を備えるものと推認される。The liquid composition of the present invention, and the coating composition obtained by blending this liquid composition into the coating, have heat resistance and flameproofness to the coated object and coating composition due to the above-mentioned appropriate viscosity, surface hardness and heat expansion. It is inferred that it imparts sex.
In particular, the liquid composition of the present invention and the coating composition in which 5 to 10 parts by mass of the coating material are mixed with 100 parts by mass of the liquid composition are similarly applied to the object to be coated due to the above-mentioned viscosity, surface hardness and heat expansion property. It is presumed that the ash shape retention performance that retains the ash shape is imparted.
Furthermore, the coating composition in which 5 to 60 parts by mass of the above liquid composition is blended with 100 parts by mass of the two-part epoxy resin coating is formed by forming a thick-film independent foam coating film in the above-described expansion process. It is assumed that it has heat insulation.

5 parts by mass of borax powder (manufactured by Maruishi Pharmaceutical Co., Ltd.) and 100 parts by mass of 1 to 40 parts by mass shown in Table 1 with respect to 100 parts by mass of water glass No. 2 (Nippon Chemical Co., Ltd. sodium silicate No. 2) Add Okinawa brown sugar (manufactured by Nissin Cup Co., Ltd.) within the range, dissolve it by heating to 70-80 ° C, then let it cool to room temperature by leaving it to cool to room temperature. . 1-7 liquid compositions were obtained.

次いで、これらの液状組成物の粘性、加熱膨張性および表面堅さを、以下のようにして調べた。
粘性は、それぞれの液状組成物に割り箸を漬けて引き上げ、目視により次の基準にて判定した。液状組成物が連続的に滴下する場合には○、ほとんど滴り落ちない場合は×とし、その中間で断続的に滴下する場合には△として表１に示した。Next, the viscosity, heat expandability, and surface hardness of these liquid compositions were examined as follows.
Viscosity was judged by visually observing the following criteria by immersing and lifting the chopsticks in each liquid composition. The results are shown in Table 1 as ◯ when the liquid composition is continuously dropped, × when the liquid composition hardly drops, and Δ when it is dropped intermittently in the middle.

加熱膨張性は、割り箸の先端にそれぞれの液状組成物を１．５ｇ程度付けて直径を計測し、８００℃程の電熱ヒーターに近づけて３分間加熱した後に、再度直径を計測して、次のように判定した。加熱後の液状組成物を付けた割り箸がシュークリームの皮状に直径２ｃｍ以上膨張した場合には○、ほとんど膨張せず、気泡ができる程度の場合には×とし、その中間で多少膨張（直径２ｃｍ未満）している場合には△として表１に示した。   Heat expandability is measured by adding 1.5g of each liquid composition to the tip of the disposable chopsticks, measuring the diameter, heating it close to an electric heater at about 800 ° C for 3 minutes, measuring the diameter again, Judged as follows. ○ when the split chopsticks with the heated liquid composition expands in diameter of 2cm or more in the cream of a cream puff, “X” when there is almost no expansion and bubbles are formed, and some expansion in the middle (diameter 2cm) If it is less than, it is shown in Table 1 as Δ.

表面堅さは、上記加熱膨張性において○と判定されたシュークリーム状に膨らんだ組成物の硬さを、指先で卵を摘む程度の力で摘み、以下のように判定した。
摘んでも全く損傷がない場合には○、簡単に壊れた場合には×とし、その中間で表面が一部剥がれた場合には△として表１に示した。The surface hardness was determined as follows by picking the hardness of the composition swelled in a cream puff shape determined to be ◯ in the heat expandability with the force of picking an egg with a fingertip.
Table 1 shows ◯ when there is no damage even when picked, x when it is easily broken, and △ when the surface is partially peeled in the middle.

表１からわかるように、液状組成物は、黒砂糖を５質量部以上加えた場合にシュークリームの皮状に適度に加熱膨張して多少の堅さを具備し、１０質量部加えた場合に所望の表面堅さが得られた。他方、黒砂糖を３０質量部以上加えた場合には粘性が高くなり、４０質量部加えた場合には、粘性が高くほとんど滴り落ちることもないため使用に適さなかった。
以上のことから、好ましい黒砂糖の添加量は、硼砂粉末５質量部に対して５〜３０質量部であることがわかった。As can be seen from Table 1, when 5 parts by mass or more of brown sugar is added, the liquid composition is moderately heated and expanded in the form of a cream puff to have some firmness, and desired when 10 parts by mass is added. The surface hardness of was obtained. On the other hand, when 30 parts by mass or more of brown sugar was added, the viscosity became high, and when 40 parts by mass was added, the viscosity was high and almost no dripping occurred.
From the above, it was found that the preferable amount of brown sugar added is 5 to 30 parts by mass with respect to 5 parts by mass of borax powder.

After that, the room temperature was changed to No. 8-14 liquid compositions were obtained. The same water glass No. 2, brown sugar and borax powder as those in Example 1 were used.
Next, the viscosity, heat expansibility and surface hardness of these liquid compositions were examined in the same manner as in Example 1 and shown in Table 2.

表２からわかるように、液状組成物は、硼砂粉末を１質量部以上加えた場合に表面が多少堅くなり、２質量部以上加えた場合に所望の堅さが得られた。他方、硼砂粉末を１５質量部以上加えた場合には粘性が高くなり、２０質量部加えた場合には、ほとんど滴り落ちないだけでなく、硼砂の一部が溶解せずに混在しており、添加剤として使用できない。
以上のことから、好ましい硼砂粉末の添加量は、黒砂糖１０質量部に対して１〜１５質量部であることがわかった。As can be seen from Table 2, the liquid composition had a slightly harder surface when 1 part by mass or more of borax powder was added, and the desired hardness was obtained when 2 parts by mass or more was added. On the other hand, when 15 parts by mass or more of borax powder is added, the viscosity becomes high, and when 20 parts by mass is added, not only does dripping hardly occur, but a part of the borax is not dissolved and mixed. Cannot be used as an additive.
From the above, it was found that the preferable addition amount of borax powder is 1 to 15 parts by mass with respect to 10 parts by mass of brown sugar.

二液型ポリウレタン１００質量部に対して、上記実験Ｎｏ．１２の液状組成物を表４に示す１〜８０質量部の範囲内で添加して、Ｎｏ．１５〜Ｎｏ．２０塗料組成物を得た。なお、二液型ポリウレタンは、主剤の軟質用ポリエステルポリオールＤ−１６１（大日本インキ化学工業（株）製）およびデスモフェン６７０（バイエル（株）製）と、硬化剤のコスモネートＮＤ（三井武田ケミカル（株）製）とからなる。また、液状組成物は、予め軟質用ポリエステルポリオールＤ−１６１に溶解した後に、デスモフェン６７０と、コスモネートＮＤとに溶解させた。[Example 4]
For 100 parts by mass of the two-component polyurethane, the above experiment No. No. 12 liquid composition was added within the range of 1 to 80 parts by mass shown in Table 4. 15-No. 20 paint compositions were obtained. The two-component polyurethane is composed of polyester polyol D-161 (manufactured by Dainippon Ink & Chemicals, Inc.) and desmophen 670 (manufactured by Bayer Co., Ltd.) as the main agents, and Cosmonate ND (Mitsui Takeda Chemical) as the curing agent. (Made by Co., Ltd.). The liquid composition was previously dissolved in the soft polyester polyol D-161 and then dissolved in desmophen 670 and cosmonate ND.

次いで、厚さ０．５ｍｍ、縦５ｃｍ、横１５ｃｍのステンレス板の片面に、上記Ｎｏ．１５〜Ｎｏ．２０の塗料組成物をそれぞれ全面塗布した（液量６ｇ）後、塗膜の発泡状態を観察して表４に示した。この発泡性の評価は、緻密な気泡（直径０．１〜０．５ｍｍ）が無数に存在して、１つ１つが独立している場合には○、さらに発泡が進んで、気泡が大きくなり、表面に大きな気泡による穴が出現し、または気泡同士が連通している場合には×、気泡が極端に小さい（直径０．１ｍｍ未満）場合には△として、目視により判定した。
なお、上記Ｎｏ．１５〜Ｎｏ．２０の塗料組成物を塗布したステンレス板は、それぞれ２枚ずつ用意して、以下のように断熱性と、耐熱性・防炎性とを評価した。Subsequently, the above No. 1 was formed on one side of a stainless steel plate having a thickness of 0.5 mm, a length of 5 cm and a width of 15 cm. 15-No. After coating each of 20 coating compositions (liquid amount 6 g), the foamed state of the coating film was observed and shown in Table 4. This foaming evaluation is based on the fact that countless bubbles (diameter 0.1 to 0.5 mm) are innumerable and each one is independent. When a hole due to a large bubble appeared on the surface or the bubbles communicated with each other, it was judged visually as x, and when the bubble was extremely small (less than 0.1 mm in diameter), Δ.
In addition, said No. 15-No. Two stainless steel plates coated with 20 coating compositions were prepared and evaluated for heat insulation, heat resistance, and flame resistance as follows.

断熱性は、電熱ヒーター上に鉄板を載せて、鉄板の表面温度を４００℃〜４５０℃に維持した状態で、上記Ｎｏ．１５〜Ｎｏ．２０の塗料組成物を塗布したステンレス板を、塗布面を表面側にしてそれぞれ鉄板上に載置して、以下のとおりに評価した。鉄板上にステンレス板を５分以上載置して、塗膜表面を指で押しても熱くない場合（５０℃未満）には○、３分未満の載置時間で、塗膜表面を指で押すと熱い場合（５０℃以上）には×、３分以上５分未満で熱くなる場合には△として表４に示した。   The heat insulation property was obtained by placing an iron plate on an electric heater and maintaining the surface temperature of the iron plate at 400 ° C. to 450 ° C. 15-No. The stainless steel plate coated with 20 coating compositions was placed on an iron plate with the coated surface as the surface side, and evaluated as follows. If the stainless steel plate is placed on the iron plate for 5 minutes or longer and the surface of the coating is not hot when pressed with a finger (less than 50 ° C), press the surface of the coating with a finger for a placement time of less than 3 minutes When it was hot (50 ° C. or more), x was shown in Table 4 as Δ when it became hot in 3 minutes or more and less than 5 minutes.

耐熱性・防炎性は、上記Ｎｏ．１５〜Ｎｏ．２０の液状組成物を塗布したステンレス板を、塗布面を表面側に向けて８００〜８５０℃の電熱ヒーター上に載置して、塗布面から煙が発生した際に、ガスライターの炎を近づけて、着火の有無および着火所要時間により、以下のように評価した。ガスライターの炎を近づけてから２分以上経過しても着火しない場合には○、直ぐに着火する場合には×、直ぐには着火しないが２分未満に着火する場合には△として、表４に示した。   For heat resistance and flameproofness, the above-mentioned No. 15-No. A stainless steel plate coated with 20 liquid composition is placed on an electric heater at 800 to 850 ° C. with the coated surface facing the surface side, and when smoke is generated from the coated surface, the flame of the gas lighter is brought closer. The following evaluations were made according to the presence or absence of ignition and the time required for ignition. Table 4 shows ◯ if the gas lighter flame does not ignite even after 2 minutes have passed since it is close, × if it ignites immediately, △ if it does not ignite immediately but ignites in less than 2 minutes, Indicated.

表４からわかるように、液状組成物を二液型ポリウレタン塗料に添加配合すると活発に発泡が生じ、５質量部添加した場合には、１つ１つ独立して存在する気泡の大きさが極端に小さかった。２０質量部以上添加した場合には、直径も大きくなり、所望の気泡が得られた。他方、６０質量部以上添加した場合には、気泡が大きくなって、表面に穴を形成する気泡や互いに連通する気泡が多く出現するようになり、８０質量部添加した場合には、このような気泡が一層多くなった。   As can be seen from Table 4, when the liquid composition is added and blended with the two-component polyurethane paint, foaming occurs actively, and when 5 parts by mass is added, the size of the bubbles that exist independently is extremely large. It was small. When 20 parts by mass or more were added, the diameter was increased, and desired bubbles were obtained. On the other hand, when 60 parts by mass or more is added, the bubbles become large, and many bubbles that form holes on the surface and bubbles that communicate with each other appear. When 80 parts by mass is added, There were more bubbles.

また、塗膜の断熱性は、液状組成物の添加量が、１質量部の場合にも多少発現し、５質量部以上の場合には充分に得られた。他方、６０質量部以上添加した場合には、添加量の増大とともに悪化した。
耐熱性・防炎性は、液状組成物の添加量が５質量の場合にも多少発現し、２０質量部以上の場合には充分に得られた。
以上のことから、好ましい液状組成物の添加量は、二液型ポリウレタン１００質量部に対して５〜６０質量部であることがわかった。Further, the heat insulating property of the coating film was somewhat exhibited even when the addition amount of the liquid composition was 1 part by mass, and was sufficiently obtained when the amount was 5 parts by mass or more. On the other hand, when 60 mass parts or more were added, it deteriorated with the increase in addition amount.
The heat resistance and flameproofness were somewhat exhibited even when the addition amount of the liquid composition was 5 mass, and was sufficiently obtained when the amount was 20 mass parts or more.
From the above, it was found that the preferable addition amount of the liquid composition is 5 to 60 parts by mass with respect to 100 parts by mass of the two-component polyurethane.

上記実験Ｎｏ．１２の液状組成物１００質量部に対して常温乾燥形アクリル樹脂ラッカー（大日本インキ化学工業（株）製）を１０質量部添加した塗料組成物（実験Ｎｏ．２１）と、上記実験Ｎｏ．１２の液状組成物１００質量部（実験Ｎｏ．２２）とを、各々市販のキッチンペーパーに塗布した。なお、これらの実験Ｎｏ．２１の塗料組成物を塗布したキッチンペーパーと、実験Ｎｏ．２２の液状組成物を塗布したキッチンペーパーとを、それぞれ２枚ずつ用意して、以下のように耐熱性・防炎性と燃焼後の灰化形状保持性とについて評価した。[Example 5]
In the above experiment No. Coating composition (Experiment No. 21) in which 10 parts by mass of a room temperature dry acrylic resin lacquer (Dainippon Ink & Chemicals, Inc.) was added to 100 parts by mass of the liquid composition of No. 12; 12 parts of the liquid composition (Experiment No. 22) was applied to commercially available kitchen paper. In addition, these experiment No. Kitchen paper coated with the coating composition of No. 21, and Experiment No. Two kitchen papers each coated with 22 liquid compositions were prepared, and the heat resistance / flame resistance and ashing shape retention after combustion were evaluated as follows.

耐熱性・防炎性は、これらの実験Ｎｏ．２１の塗料組成物を塗布したキッチンペーパー又は実験Ｎｏ．２２の液状組成物を塗布したキッチンペーパーを、それぞれ８００℃の電熱ヒーターに塗膜が接するように載置して、直接加熱した外は、上記実施例４と同様にして評価して表５に示した。   The heat resistance and flameproofness of these Nos. Kitchen paper coated with the coating composition of No. 21 or Experiment No. Table 5 was evaluated in the same manner as in Example 4 except that the kitchen paper coated with 22 liquid compositions was placed so that the coating film was in contact with an electric heater at 800 ° C. and heated directly. Indicated.

燃焼後の灰化形状保持性は、実験Ｎｏ．２１又は実験Ｎｏ．２２の液状（塗料）組成物を塗布したキッチンペーパーを、それぞれ陶芸用の電気炉に入れて加熱し、１２００℃の高温雰囲気により１時間加熱した後に、取り出して、形状の変化を目視により以下のように判定した。燃焼前の形状がわかる程度に保持されていれば○、燃焼前の形状がわからない場合には×として、表５に示した。   The ashing shape retention after combustion was confirmed by Experiment No. 21 or Experiment No. The kitchen paper coated with the liquid (paint) composition of 22 was put in an electric furnace for ceramics, heated, heated for 1 hour in a high-temperature atmosphere at 1200 ° C., then taken out, and the change in shape was visually observed as follows. Judged as follows. The results are shown in Table 5 as ◯ if the shape before combustion is known to the extent that it can be understood, and x when the shape before combustion is not known.

表５からわかるように、液状組成物及びこれを塗料により溶解した塗料組成物は、耐熱性・防炎性のみならず燃焼後の灰化形状保持性を有する。
なお、液状組成物または塗料組成物を塗布したキッチンペーパーは、ともに２００℃近辺から小さな気泡が発生するものの、６００℃を超えると透明になり、灰化が進行するものの燃焼前の形状を保持していた。As can be seen from Table 5, the liquid composition and the coating composition obtained by dissolving it with a coating material have not only heat resistance and flame resistance but also ash shape retention after combustion.
Note that the kitchen paper coated with the liquid composition or the coating composition both generates small bubbles from around 200 ° C, but becomes transparent when the temperature exceeds 600 ° C, and maintains the shape before combustion although ashing proceeds. It was.

水性アクリルエマルジョンとしては、水性カチオンエマルション塗料ＵＷ５２０（大成化工（株）製）を用いて、アクメ乾燥器Ｂ−１型（（株）高杉製作所）により３０分間６０℃雰囲気に保ち乾燥させた。同様に、アクリルラッカーは、常温乾燥形アクリル樹脂ラッカー（大日本インキ化学工業（株）製）を用いて、３０分間６０℃雰囲気に保ち乾燥させた。焼付形アクリルメラミン樹脂は、焼付形アクリル樹脂塗料（大日本インキ化学工業（株）製）を用いて、３０分間１６０℃雰囲気に保ち乾燥させた。
また、二液形エポキシ樹脂塗料は、主剤のエピクロンＨ２０１−６０ＢＴ（大日本インキ化学工業（株）製）１０質量部に対し、硬化剤のトーマイド２１５−７０Ｘポリアミドアミンエポキシ硬化剤（富士化成工業（株）製）１質量部を配合したものを用いて、常温乾燥させた。As the aqueous acrylic emulsion, an aqueous cation emulsion paint UW520 (manufactured by Taisei Kako Co., Ltd.) was used and dried in an acme dryer B-1 type (Takasugi Seisakusho Co., Ltd.) for 30 minutes. Similarly, the acrylic lacquer was dried in a 60 ° C. atmosphere for 30 minutes using a room temperature drying acrylic resin lacquer (manufactured by Dainippon Ink & Chemicals, Inc.). The baking-type acrylic melamine resin was dried by keeping it in an atmosphere of 160 ° C. for 30 minutes using a baking-type acrylic resin paint (manufactured by Dainippon Ink & Chemicals, Inc.).
In addition, the two-pack type epoxy resin coating is based on 10 parts by mass of the main agent Epicron H201-60BT (manufactured by Dainippon Ink & Chemicals, Inc.), a tomide 215-70X polyamidoamine epoxy curing agent (Fuji Kasei Kogyo ( It was dried at room temperature using a blend of 1 part by mass.

このようにして得られた実験Ｎｏ．２３〜Ｎｏ．２６の塗料又は塗料組成物を塗布した軟鋼板を、それぞれ塗膜面にブンゼンバーナーの火炎が触れるように直接加熱して、塗布面から煙が発生（着火）した際の非塗布面である軟鋼板裏面の温度を、放射温度計（林電工（株）製）で測定して表６に示した。   Experiment No. obtained in this way. 23-No. Mild steel sheet coated with 26 paint or paint composition is heated directly so that the flame of the Bunsen burner touches the paint film surface, and mild steel is the non-coated surface when smoke is generated (ignition) from the coated surface. The temperature on the back of the plate was measured with a radiation thermometer (manufactured by Hayashi Denko Co., Ltd.) and shown in Table 6.

表６からわかるように、塗料１００質量部に上記実験Ｎｏ．１２の液状組成物４０質量部を添加する前の塗料と比較すると、添加した後の塗料組成物は、着火温度が高く、耐熱性・防炎性に優れていた。特に、水性アクリルエマルジョンおよびアクリルラッカーは、塗料そのものの着火温度が１２０℃〜１２５℃と比較的低い温度であるが、液状組成物を添加すると着火温度が３３０℃〜３５０℃になり、２００℃以上も高くなり、その効果が絶大である。
また、塗料組成物の耐熱性・防炎性を重視するのであれば、二液形エポキシ樹脂に液状組成物を添加すると３９０℃〜４１０℃と最も着火温度の高い塗料組成物が得られることがわかる。As can be seen from Table 6, the experiment No. Compared with the paint before adding 40 parts by mass of the 12 liquid composition, the paint composition after the addition had a high ignition temperature and was excellent in heat resistance and flame resistance. In particular, the aqueous acrylic emulsion and the acrylic lacquer have a relatively low ignition temperature of 120 ° C. to 125 ° C., but when the liquid composition is added, the ignition temperature becomes 330 ° C. to 350 ° C., which is 200 ° C. or higher. The effect is enormous.
Also, if the heat resistance and flameproofness of the coating composition are important, a coating composition having the highest ignition temperature of 390 ° C. to 410 ° C. can be obtained by adding the liquid composition to the two-pack type epoxy resin. Recognize.

本発明の液状組成物はまた、アスベストを浸漬しておくだけで、アスベストの繊維状の針状結晶を膨潤破壊して無害化する処理剤として使用することができる。さらには、この処理剤をアスベストの吹き付け面に直接塗布することにより、アスベストの飛散防止・封じ込めを行うことができ、処理剤を塗布したアスベスト吹き付け面から回収したアスベスト廃棄物を加熱燃焼することによって、アスベストは無害化され、ホウ酸ガラスとして安定な固化物とすることができる。   The liquid composition of the present invention can also be used as a treatment agent that swells and destroys the fibrous needle-like crystals of asbestos just by immersing asbestos. Furthermore, by applying this treatment agent directly to the sprayed surface of asbestos, it is possible to prevent and contain the asbestos from being scattered. Asbestos can be rendered harmless and can be a stable solidified product as borate glass.

また、本発明の液状組成物を、添加剤として一般的な塗料に添加配合することにより、耐熱性や防炎性に優れた塗料組成物を得ることができる。
さらには、本発明の液状組成物に少量の塗料を配合した塗料組成物は、液状組成物そのままの処理剤と同様に、耐熱性や防炎性に優れ、証券・証書や重要文書等に直接塗布しても、外観上特に遜色がなく、火災にあって燃焼した場合には灰化形状を保持し得る処理剤として使用できる。Moreover, the coating composition excellent in heat resistance and flameproofness can be obtained by adding and blending the liquid composition of this invention to a general coating material as an additive.
Furthermore, the coating composition in which a small amount of coating is blended with the liquid composition of the present invention is excellent in heat resistance and flameproofness, just like the treatment agent of the liquid composition as it is, and directly on securities, certificates, important documents, etc. Even if it is applied, there is no particular discoloration in appearance, and it can be used as a treatment agent that can maintain an ashed shape when burned in a fire.

さらにまた、本発明の液状組成物を二液型ポリウレタン樹脂塗料に添加配合した塗料組成物は、独立発泡塗膜を形成するため、オートバイのマフラーや燃焼炉のダクト等の高温加熱箇所にかような塗料を塗布することにより、断熱性に優れた塗膜を形成して、塗膜の上から手を触れても火傷の危険のない触感温度をもたらすことができる。   Furthermore, the coating composition obtained by adding the liquid composition of the present invention to the two-component polyurethane resin coating forms an independent foamed coating film, so that it may be applied to high-temperature heating locations such as motorcycle mufflers and combustion furnace ducts. By applying a coating material, it is possible to form a coating film excellent in heat insulating properties, and bring about a tactile sensation temperature that does not cause a burn even if the hand is touched from above the coating film.
