し成形して作られている。[Prior Art] In general, a friction brake device for an automobile is composed of brake shoes and a brake drum or brake disc, etc., and applies braking force by hydraulically pressing the brake shoes against the brake drum or the like that rotates with the tires. It is a system for giving. The surface of the brake shoe is covered with a brake lining, which is usually made of asbestos bonded with resin, rubber, etc. to ensure wear resistance and noncombustibility.

必要とされる事柄は以下のとおりである。すなわち、
(1)洗浄作業中にアスベスト粉塵等が飛散しないこと
、
(2)ブレーキ部品洗浄後は次の作業に移ることができ

(6)人体に対する悪影響のないこと(有機溶剤中毒予
防規則の対象となっていないこと)、が必要とされる。This brake lining gradually wears out as the brake gear is used. As a result, asbestos dust is generated and adheres to the brake lining surface, brake drum, etc., and adversely affects brake performance. In addition to replacing brake oil, removing asbestos dust S is an important item during vehicle inspections. In addition, the dust and oil-based contaminants of brake devices adhere to rubber parts such as cylinder boots, etc., and this obstructs the work of operators by staining their hands during disassembly and inspection. During a vehicle inspection, the tires and brake drums are first removed, and after removing asbestos dust and oil-based contaminants using some cleaning method, the brake system is disassembled, inspected, and parts replaced, etc., but this cleaning method requires the following: It is as follows. In other words, (1) asbestos dust etc. should not be scattered during cleaning work, (2) after cleaning brake parts, dry them promptly so that you can move on to the next work, (3) after cleaning brake parts, especially No residue of cleaning ingredients will remain on brake linings, brake drums, etc. (4) No damage to rubber parts such as cylinder boots installed as brake parts, (5) No damage to metal parts such as brake drums or springs. (6) It must not cause any harmful effects on the human body (not be subject to organic solvent poisoning prevention regulations).
一方、現在行なわれている一般的な洗浄方法には次の3
方法が挙げられる。On the other hand, there are three common cleaning methods currently in use:
There are several methods.
■ コンプレッサーを用いて圧縮空気を発生させ粉塵を
吹き飛ば1方法。■ One method is to use a compressor to generate compressed air and blow away dust.
粉塵が空気中に飛散する為、作業環境の汚染が著しく大
きい。また、アスベスト粉塵には癌を誘発する力がある
とも言われている為、作業者の健康上好ましくない。さ
らに油系の汚染物を取除く事は困難である。Dust is scattered into the air, resulting in significant pollution of the working environment. Furthermore, asbestos dust is said to have the ability to induce cancer, so it is not good for the health of workers. Furthermore, it is difficult to remove oil-based contaminants.
■ 塩素系有機溶剤を主成分とするエアゾール剤による
湿式洗浄方法。■ Wet cleaning method using an aerosol agent whose main ingredient is a chlorinated organic solvent.
塩素系有機溶剤(例えば、トリクロロエチレン、1.1

毒性の強い溶剤である為、労働安全衛生法に基づく有機
溶剤中毒予防規則の対重物質となっている。この為、使
用にあたっては各作業所で次の事柄を満足する必要性が
ある。Chlorinated organic solvents (e.g. trichlorethylene, 1.1
.. 1-)-Dichloroethane, etc.) are generally highly toxic solvents due to their vapors, and therefore are subject to the Organic Solvent Poisoning Prevention Regulations based on the Industrial Safety and Health Act. For this reason, each workplace must satisfy the following requirements when using the product.
・局所排気8Mまたは発散源密開設備などの滴設
・有機溶剤作業主任者の選任

最も一般的な方法であったが、昨今のフロン問題を鑑み
ると近い将来使用不可能となることは容易に推定される
。すなわち主成分であるフロン113はフロン規制の対
象物質となっており、また価格も上昇しつつある。This was the most common method, but considering the recent problems with fluorocarbons, it is easy to assume that it will become unusable in the near future. In other words, the main component, fluorocarbon 113, is a substance subject to fluorocarbon regulations, and its price is also rising.
[発明が解決しようとする課題]
以上のように自動車のブレーキ装置の洗浄方法は、実際
上、上記の方法を実施することが困難となったため、新
たな方法の開発が急務とされている。[Problems to be Solved by the Invention] As described above, since it has become difficult to actually implement the above-mentioned method for cleaning a brake device of an automobile, there is an urgent need to develop a new method.

ない。When handling hazardous substances that exceed the discharge rate specified in Table 1, please use the "
It is necessary to set up a "storage facility" and store or handle it based on technical standards specified by government ordinance. The first petroleum is a highly flammable solvent, typified by gasoline, and penetrates into the rubber parts of the brake device, causing them to swell. In addition, the first petroleum type dries too quickly, causing contaminants to re-adhere to brake parts, and the specified quantity is also small, so it is not preferred as a cleaning fluid for player equipment from a logistics standpoint.
一方、第3石油類はブレーキ装置のゴム部分を膨潤させ
ない反面、乾燥が極めて遅い為、作業上 。On the other hand, while No. 3 petroleum does not swell the rubber part of the brake system, it dries extremely slowly, making it difficult to work with.
