Description

ガソリンスタンドの床の施工方法およびテープGas station floor construction method and tape

本発明は、ガソリンスタンド等における人体帯電除去不足による火災発生を防止するための床施工方法に関するものである。The present invention relates to a floor construction method for preventing the occurrence of a fire due to insufficient removal of electrification of a human body at a gas station or the like.

ガソリンスタンドは人件費軽減のため、セルフサ−ビス化が急速に進んでいる。
危険物等事故防止技術センタ−の報告書では、セルフサービススタンドの平成10〜15年の5年間火災発生は27件である。この内、人体帯電除去不足によるものが15件(55.6%)で第1位である。一方セルフサービススタンド(全給油取扱所)では558件の火災が発生し、この内人体帯電除去不足によるものが13件(2.2%)である。また平成19年3月末のガソリンスタンド数は45790ケ所である。
Gas stations are rapidly becoming self-service to reduce labor costs.
According to the report from the Technical Center for Hazardous Material Accident Prevention, there were 27 fires in the self-service stand for 5 years from 1998 to 2015. Of these, 15 cases (55.6%) were due to insufficient charge removal from the human body, which was ranked first. On the other hand, there were 558 fires at the self-service stand (all refueling stations), and 13 cases (2.2%) were caused by insufficient charge removal from the human body. The number of gas stations at the end of March 2007 was 45790.

ドライバ−はガソリン給油作業に慣れていない人が多く、人体に3kv以上の静電気を帯びたままで給油機を操作している場合が多い。その為、給油機の金属部分に人体が触れた時に火花放電をすることがある。ガソリンタンクのフタを開いた時にタンク内から立ち昇る霧状のガソリンに引火して火災が発生することがある。 Many drivers are unfamiliar with gasoline refueling work and often operate the refueling machine with static electricity of 3 kV or more on the human body. Therefore, spark discharge may occur when a human body touches the metal part of the fueling machine. When the lid of a gasoline tank is opened, a mist of gasoline rising from the tank may ignite and a fire may occur.

セルフサービススタンドの人体帯電除去には次の問題点がある。
(1)給油活動中の静電気帯電は車の座席から立ち上がった時、衣服とシ−トの剥離帯電が起きているが、人体に感じていない。
(2)通常人体に3kv以上の帯電があった場合、導電体との間で放電が起こり、ガソリン等の低引火点危険物の可燃性蒸気に引火し火災を起こすエネルギ−がある。
(3) セルフサービススタンドを利用する顧客は、ガソリン等の危険物についての危険性や安全な取扱いについての知識を持っていない。ア−スボタンに触れない時がある。
There are the following problems in removing the electrification of the human body from the self-service stand.
(1) Static charge during refueling activities, when standing up from the seat of a car, is caused by peeling of clothes and sheets, but it is not felt by the human body.
(2) Normally, when the human body is charged with 3 kV or more, there is an energy that causes a fire by causing a discharge between the conductor and igniting a combustible vapor of a low flash point dangerous material such as gasoline.
(3) Customers who use self-service stands do not have knowledge about the dangers and safe handling of dangerous goods such as gasoline. Sometimes you don't touch the ground button.

以上の事から、顧客が事前に人体帯電を除去することなく給油しても、除電方法を知らなくても、除電が出来る新たな対策が必要である。静電気を防ぐには、接地(ア−ス)による方法。湿度の増大、静電気中和除去による方法などがある。 From the above, there is a need for a new measure that can eliminate the charge even if the customer refuels without removing the human body charge in advance or does not know the charge removal method. To prevent static electricity, use a grounding method. There are methods such as increasing humidity and neutralizing static electricity.

1、ア−スによる方法は、導電化のため導線を用い接地抵抗を100オーム以下にする必要があるが、確実に電荷を逃がすことが出来るのは導体の場合であり、靴底が合成樹脂製品であると絶縁体となり静電気除去には限界がある。 1. The method based on earth requires conducting wires to make the ground resistance less than 100 ohms for electrical conductivity, but it is the case of conductors that can surely release the charge, and the sole is made of synthetic resin. If it is a product, it becomes an insulator and there is a limit to static electricity removal.

2、湿度による除電は。散水や加湿器により、相対湿度を65%以上まで増大させ維持する必要がある。しかし、ガソリンスタンドは外気に開放されているため、湿度の維持が困難である。 2. Static elimination due to humidity. It is necessary to increase and maintain the relative humidity to 65% or more by watering or a humidifier. However, since the gas station is open to the outside air, it is difficult to maintain humidity.

3、炭素繊維を用いた自己放電式除電器による除電は、空気をイオン化し帯電物質電荷を中和するもので、限られた場所の静電気を有効に除去することが出来る。 3. Static elimination by a self-discharge type static eliminator using carbon fiber is to ionize air and neutralize charged substance charges, and can effectively remove static electricity in a limited place.

本発明は、人体に帯電している静電気を効果的に除去することにより、セルフサービススタンド等の人体帯電に起因する火災等の発生を防止することを課題としている。 An object of the present invention is to prevent the occurrence of a fire or the like due to human body charging such as a self-service stand by effectively removing static electricity charged on the human body.

耐候性、耐油性の水性塗料に、炭素繊維の繊維長3mmから12mmの短繊維を2〜10%(owf)の割合で均一に混合分散したものでコンクリ−トの床を塗装する。さらに、その周辺に、不織布に、炭素繊維の繊維長3mmから12mmの短繊維を2〜10%(owf)の割合でコーティングし裏面にアルミ箔を貼る。 The concrete floor is coated with a weather-resistant and oil-resistant water-based paint in which short fibers having a fiber length of 3 to 12 mm are uniformly mixed and dispersed at a ratio of 2 to 10% (owf). Further, a short fiber having a carbon fiber length of 3 mm to 12 mm is coated on the non-woven fabric at a ratio of 2 to 10% (owf) , and an aluminum foil is pasted on the back surface.

顧客又は給油所作業員は給油作業をするに当たり、この炭素繊維の短繊維の塗装又はコ−ティングテーフ゜の上を歩く事になり、自動的に人間の人体帯電は中和される。 When a customer or a gas station worker performs a refueling operation, he / she walks on the carbon fiber short fiber coating or coating table, and the human body charge is automatically neutralized.

中和現象とは、帯電した物質に繊維状導電物質が接触すると、その先端がアンテナとなり帯電体との反対のイオン+か−が集まり、帯電体のイオンと結合して帯電を無くする事である。この現象は繊維状導電物質にのみ起こる現象で、繊維長3mm〜12mmを使う事が経済的である。繊維状導電物質とは、ステンレス繊維、金属メッキ合金、炭素繊維があるが価格、耐久性から見て炭素繊維が最もすぐれている。除電性を表1に示す Neutralization is a phenomenon in which when a fibrous conductive material comes into contact with a charged substance, its tip becomes an antenna and ions + or-opposite to the charged body gather and combine with the ions of the charged body to eliminate the charge. is there. This phenomenon occurs only in the fibrous conductive material, and it is economical to use a fiber length of 3 mm to 12 mm. Examples of fibrous conductive materials include stainless steel fibers, metal plating alloys, and carbon fibers, but carbon fibers are the best in terms of price and durability. Table 1 shows the charge removal performance.

炭素繊維の機能は、大気中のイオン(電子)を自動的に集める。プラス帯電した人体があると炭素繊維にマイナスイオンが集まり人体のプラスイオンと炭素繊維にマイナスイオンが中和し、人体帯電を除去する。 The function of carbon fiber is to automatically collect ions (electrons) in the atmosphere. If there is a positively charged human body, negative ions are collected in the carbon fiber, and the positive ions in the human body and the negative ion are neutralized in the carbon fiber to remove the human body charge.

所定長さの炭素繊維を塗料に均一分散させることにより、人体帯電を効果的に除去できる床を簡単に提供できる。  By uniformly dispersing carbon fibers having a predetermined length in the paint, a floor capable of effectively removing human body charge can be easily provided.

以下実施例により本発明を詳述する。アクリルニトル系重合繊維から標準的条件により製造した炭素繊維を3mmの繊維長にカットする。これには炭素繊維製造時に添加したサイジング剤が数パーセント付着しており、3mmにカットしても、なかなか1本毎の繊維に分離しない。サイジング剤を昇華して取り除くために加熱炉で800℃。15分間の熱処理をした後、自然冷却し、水中にて攪拌した。攪拌機は2000R/Mで10分間処理すると繊維はよく分離した。これに規定の塗料(耐候性、耐油性)を加えて、更に10分間攪拌した。出来上がった炭素繊維混合塗料は5時間以内にガソリンスタンド設備の周辺の所定の面積に塗装した。 The present invention will be described in detail below with reference to examples. Carbon fibers produced from acrylic nitrile polymer fibers under standard conditions are cut to a fiber length of 3 mm. The sizing agent added at the time of carbon fiber manufacture adheres to this, and even if it cuts to 3 mm, it does not separate easily into every fiber. 800 ° C in a heating furnace to sublimate and remove the sizing agent. After heat treatment for 15 minutes, it was naturally cooled and stirred in water. The fibers were well separated when the stirrer was treated at 2000 R / M for 10 minutes. The specified paint (weather resistance, oil resistance) was added thereto, and the mixture was further stirred for 10 minutes. The finished carbon fiber mixed paint was applied to a predetermined area around the gas station facility within 5 hours.

ガソリンスタンド周辺の塗装する面積部分には下記の下地準備をしておく。
1.素地調整 ウエスや刷毛で下地の汚れを除去する。
2.下塗り 弾性シ−ラ−をロ−ラ−刷毛で塗布する。
塗布量は0.1kg/m2で乾燥時間は2時間
Prepare the following groundwork for the area to be painted around the gas station.
1. Substrate adjustment Remove dirt on the ground with a waste cloth or brush.
2. Undercoat Apply an elastic sealer with a roller brush.
The coating amount is 0.1kg / m2 and the drying time is 2 hours

本発明の塗料の塗装後は、24時間以上養生をした後、施工された床の周囲に、不織布に炭素繊維の繊維長3mmから12mmの短繊維を2〜10%(owf)を均一に分散してコーティングし、裏面にアルミ箔と接着剤を重ねてラミネ−トした床の施工用テ−プを貼着した。その後ガソリン給油作業をし、給油作業者が自動車をスタンド設備横に停車して、下車したときの人体帯電を測定したところ3.9kvであった。同一人が本発明の塗装場所に入り、1分後人体帯電を測定したところ2.1kvであった。したがって、除電効果はあった。なお、作業者の衣服はポリエステル/レーヨン混、靴は底がゴム製のスポ−ツシュ−ズを着用していた。 After applying the paint of the present invention, after curing for 24 hours or more, 2-10% (owf) of short fibers having a carbon fiber length of 3 mm to 12 mm are uniformly dispersed on the non-woven fabric around the floor where the work is applied. Then, the tape for construction of the floor which laminated the aluminum foil and the adhesive on the back and laminated was stuck. After that, gasoline refueling work was performed, and when the refueling worker stopped the car next to the stand equipment and got off, the human body charge was measured to be 3.9 kv. When the same person entered the painting place of the present invention and measured the human body charge after 1 minute, it was 2.1 kv. Therefore, there was a static elimination effect. The worker's clothing was a polyester / rayon blend, and the shoes were wearing sports shoes with a rubber bottom.

アクリルニトル系重合繊維から、標準的条件により製造した炭素繊維を12mmの繊維長にカットし、加熱炉で800℃×15分間の熱処理をした。これに水を加えて、攪拌機で2000R/M×10分間攪拌した。 Carbon fibers produced under standard conditions were cut from acrylic nitrile polymer fibers into a fiber length of 12 mm and heat-treated at 800 ° C. for 15 minutes in a heating furnace. Water was added thereto, and the mixture was stirred with a stirrer at 2000 R / M × 10 minutes.

タテ300mm、ヨコ300mm、厚さ50mmのコンクリ−ト板をモルタル仕上げしたセメント板にプライマ−をスプレ−で下塗りをして4時間乾燥した。上塗りして4時間乾燥した。上塗りとして、合成樹脂エマルションペイント(JIS k5663)の第1種(屋外用暴露耐候性)を基材として、これに上記炭素繊維の攪拌済みのものを7%owf混合して1000R/M×5分間攪拌した塗料を刷毛塗装した。 A primer was coated with a spray on a mortar-finished cement board having a length of 300 mm, a width of 300 mm, and a thickness of 50 mm, and dried for 4 hours. It was overcoated and dried for 4 hours. As a top coat, synthetic resin emulsion paint (JIS k5663) type 1 (exposure weathering for outdoor use) is used as a base material, and 7% owf of the above-mentioned carbon fiber agitated material is mixed with it at 1000 R / M × 5 minutes. The stirred paint was brush painted.

24時間乾燥をして見本板を作った。表面を5倍の拡大鏡で観察すると炭素繊維が分散している事が確認出来た。 Samples were made after drying for 24 hours. When the surface was observed with a magnifier of 5 times, it was confirmed that carbon fibers were dispersed.

島津製作所製静電高圧発生装置(ハ゜ンテ゛ク゛ラフ起電機)で10000vの静電気を発生させ火花放電を起し、パチパチという火花を観察した。ここへ前記、炭素繊維塗装見本板を近づけると20〜50mmの間隔の非接触でも、火花放電は消えた。接触すると完全に消える。これは炭素繊維の短繊維による静電気中和現象によるもので、実施例1と同じ効果であった。静電気量は10000vから1000vに減衰した。 Shimadzu's electrostatic high voltage generator (handcraft generator) generated 10000v of static electricity to cause a spark discharge, and a crack was observed. When the carbon fiber coating sample plate was brought close to this, the spark discharge disappeared even in a non-contact manner with an interval of 20 to 50 mm. It disappears completely on contact. This was due to the electrostatic neutralization phenomenon caused by the short fibers of carbon fibers, and the same effect as in Example 1. The amount of static electricity was attenuated from 10000v to 1000v.
