近年、アスベスト含有建材が経年劣化や脆弱化に伴う剥離、落下、あるいは解体時の飛散などによって人体への健康被害が及んで社会問題になっている。また、このアスベスト含有建材の除去処理工事においては、飛散するアスベスト繊維の低減と作業所以外に飛散するのを防ぐために負圧・除塵装置（高価で専門的な維持管理が必要）を設置して行っている。これは作業箇所を養生シートで厳密に囲み、その中に特別な保護衣と呼吸保護具を装備した作業者が入ってケレン棒やスクレーパなどを用いて除去作業を行っている。この除去したアスベストはプラスチック袋の中に入れて飛散防止剤で湿潤化させるか、セメントで固化させている。また除去作業の終了後、高価な高性能真空掃除機で床などの清掃を行っている。   In recent years, asbestos-containing building materials have become a social problem due to health damage to the human body due to peeling, dropping, or scattering at the time of dismantling due to aging and weakening. In addition, in this asbestos-containing building material removal processing work, a negative pressure / dust removal device (expensive and specialized maintenance management is required) is installed to reduce the amount of scattered asbestos fibers and prevent them from scattering outside the work place. Is going. In this, the work site is strictly surrounded by a curing sheet, and an operator equipped with special protective clothing and breathing protection equipment enters it and removes it using a keren rod or scraper. The removed asbestos is put in a plastic bag and moistened with an anti-scattering agent or solidified with cement. After the removal work, the floor is cleaned with an expensive high-performance vacuum cleaner.

しかし上記のアスベスト層の除去方法は、負圧・除塵装置や高性能真空掃除機などを使用する他、作業者が特別な保護衣と呼吸保護具を装備するためにコストがかかるという問題があった。また作業者がケレン棒やスクレーパなどを用いてアスベスト層を除去しているため多大な時間と労力を必要としていた。   However, the above asbestos layer removal method involves the use of negative pressure / dust removal equipment, high-performance vacuum cleaners, etc., as well as the problem that the operator is required to wear special protective clothing and respiratory protective equipment. It was. Further, since the worker removes the asbestos layer using a keren rod or a scraper, a great amount of time and labor are required.

そこで、乾式吹付け剤、有機系吹付け剤、無機系吹付け剤、または飛散防止剤をアスベストに吹付け塗布してこれを封じ込める方法をとっている。またその他のアスベストの飛散防止方法として、例えば特開平１０−３２３６１４号公報の発明がある。
特開平１０−３２３６１４号公報 Therefore, a dry spray agent, an organic spray agent, an inorganic spray agent, or an anti-scattering agent is sprayed onto asbestos to contain it. As another asbestos scattering prevention method, for example, there is an invention of JP-A-10-323614.
JP-A-10-323614

しかし上記の乾式吹付け剤は、湿式吹付け耐火被覆材に対しては浸透しない問題があった。また有機系吹付け剤は建築基準法などによる防・耐火規定に適合しない問題があった。また無機系吹付け剤は梁、柱などの動きのある部材には適用することができないという問題があった。または飛散防止剤を用いて固化した場合は、吸音・断熱性能などの基材性能を損なうものが多いという問題があった。   However, the dry spray agent has a problem that it does not penetrate into the wet spray fireproof coating material. In addition, organic sprays have a problem that they do not conform to the fire prevention and fire resistance regulations of the Building Standard Law. Further, there has been a problem that inorganic sprays cannot be applied to moving members such as beams and columns. Or, when solidified using an anti-scattering agent, there is a problem that many of the materials deteriorate the base material performance such as sound absorption and heat insulation performance.

本願発明は上記の課題を解決するためになされたものであり、その目的はアスベストの飛散を防止し、かつ下地の動きがある柱・梁などにも適用することができるアスベストの飛散防止方法を提供することである。   The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to prevent asbestos from being scattered, and to prevent asbestos from being scattered. Is to provide.

上記の課題を解決するための本願発明のアスベスト飛散防止剤は、水性有機系浸透剤と、発泡剤と、難燃剤と、金属酸化物と、分散剤と、混和剤とからなることを特徴とする。また水性有機系浸透剤が５０〜５５重量％、発泡剤が３０〜３５重量％、難燃剤が６〜１２重量％、金属酸化物が１〜３重量％、分散剤が１〜３重量％、混和剤が１〜３重量％であることを含むものである。   The asbestos scattering inhibitor of the present invention for solving the above problems is characterized by comprising an aqueous organic penetrant, a foaming agent, a flame retardant, a metal oxide, a dispersant, and an admixture. To do. Further, the aqueous organic penetrant is 50 to 55% by weight, the foaming agent is 30 to 35% by weight, the flame retardant is 6 to 12% by weight, the metal oxide is 1 to 3% by weight, the dispersant is 1 to 3% by weight, This includes that the admixture is 1 to 3% by weight.

またアスベストの飛散防止方法は、水性有機系浸透剤と、発泡剤と、難燃剤と、金属酸化物と、分散剤と、混和剤とからなるアスベスト飛散防止剤を、吹付け施工された既存のアスベスト層に吹付け塗布することを特徴とする。また水性有機系浸透剤が５０〜５５重量％、発泡剤が３０〜３５重量％、難燃剤が６〜１２重量％、金属酸化物が１〜３重量％、分散剤が１〜３重量％、混和剤が１〜３重量％であることを含むものである。   In addition, asbestos scattering prevention method is an existing asbestos scattering prevention agent sprayed with an aqueous organic penetrant, a foaming agent, a flame retardant, a metal oxide, a dispersant, and an admixture. It is characterized by spraying on the asbestos layer. Further, the aqueous organic penetrant is 50 to 55% by weight, the foaming agent is 30 to 35% by weight, the flame retardant is 6 to 12% by weight, the metal oxide is 1 to 3% by weight, the dispersant is 1 to 3% by weight, This includes that the admixture is 1 to 3% by weight.

またアスベスト飛散防止剤において、水性有機系浸透剤が５０重量％未満の場合は動きのある部材には追従しにくくなり、５５重量％を越えると浸透性が悪くなる。また発泡剤が３０重量％未満の場合は発泡しにくくなり、３５重量％を越えると過剰な発泡になる。また難燃剤が６重量％未満の場合は難燃性が低下し、１２重量％を越えると物性が悪くなる。また金属酸化物が１重量％未満の場合は難燃性が低下し、３重量％を越えると混和しにくくなる。また分散剤が１重量％未満の場合は分散性が低下し、３重量％を越えると気泡が入りやすくなる。また混和剤が１重量％未満の場合は耐久性が低下し、３重量％を越えると付着性が悪くなる。   Further, in the asbestos scattering inhibitor, when the aqueous organic penetrant is less than 50% by weight, it is difficult to follow a moving member, and when it exceeds 55% by weight, the penetrability is deteriorated. When the foaming agent is less than 30% by weight, foaming is difficult to occur, and when it exceeds 35% by weight, excessive foaming occurs. On the other hand, when the flame retardant is less than 6% by weight, the flame retardancy decreases, and when it exceeds 12% by weight, the physical properties are deteriorated. Further, when the metal oxide is less than 1% by weight, the flame retardancy is lowered, and when it exceeds 3% by weight, it becomes difficult to mix. Further, when the dispersant is less than 1% by weight, the dispersibility is lowered, and when it exceeds 3% by weight, bubbles tend to enter. Further, when the admixture is less than 1% by weight, the durability is lowered, and when it exceeds 3% by weight, the adhesion is deteriorated.

柱や梁などの動きのある部材におけるアスベストにも適用することができる。また火災時においても耐火性、吸音、断熱性などのアスベスト基材の所定の性能を保持することができる。アスベストを封じ込めた後に飛散させずに除去することができる。また環境改善への社会的な貢献をすることができる。   It can also be applied to asbestos in a moving member such as a column or beam. Moreover, the predetermined performance of asbestos base materials, such as fire resistance, sound absorption, and heat insulation, can be maintained also at the time of a fire. After containing asbestos, it can be removed without scattering. It can also make social contributions to environmental improvements.

以下、本願発明のアスベスト飛散防止剤の実施の形態を図面に基づいて説明する。このアスベスト飛散防止剤は水性有機系浸透剤とカバーリング剤とから構成され、このアスベスト飛散防止剤における水性有機系浸透剤としては、柔軟性のある超微粒子有機系エマルションのアクリル樹脂系、酢酸ビニル樹脂系、エチレン酢酸ビニル樹脂系、ポリビニルアルコール、塩化ビニル樹脂系、ウレタン樹脂系のうちのいずれか一つが使用される。   Hereinafter, embodiments of the asbestos scattering inhibitor of the present invention will be described with reference to the drawings. This asbestos scattering inhibitor is composed of an aqueous organic penetrating agent and a covering agent. As the aqueous organic penetrating agent in this asbestos scattering preventing agent, flexible ultrafine organic emulsion acrylic resin-based, vinyl acetate Any one of a resin system, an ethylene vinyl acetate resin system, a polyvinyl alcohol, a vinyl chloride resin system, and a urethane resin system is used.

次に、このアスベスト飛散防止剤を使用したアスベストの飛散防止方法について説明する。これは建物の天井、壁面および耐熱の必要な箇所に吹付け施工されたアスベスト層を簡単かつ確実に除去しようとするものであり、本実施の形態においては天井に吹付け施工されたアスベスト層を対象に説明する。   Next, an asbestos scattering prevention method using this asbestos scattering inhibitor will be described. This is an attempt to easily and reliably remove the asbestos layer sprayed on the ceiling, wall surface, and heat-resistant part of the building. In this embodiment, the asbestos layer sprayed on the ceiling is removed. Explain to the subject.

この飛散防止方法は、建物の天井、壁面および耐熱の必要な箇所に吹付け施工されたアスベスト層にアスベスト飛散防止剤を吹付け塗布してこれを封じ込めて、その飛散を防止しようとするものであり、本実施の形態においては天井に吹付け施工されたアスベスト層を対象に説明する。   This scattering prevention method is intended to prevent the scattering by spraying and applying an asbestos scattering prevention agent to the asbestos layer sprayed on the ceiling, walls and heat-resistant areas of the building.
