のである。Due to these properties, attempts have been made to use it as a waterproof coating, but when applied as a solution, the adhesion to the substrate, tensile strength, weather resistance, and abrasion resistance are fully satisfactory. What should have been done could not be changed, and in the end, the method used for waterproofing was to form butyl rubber into sheets and paste them with adhesive on site for waterproofing work.

性がすぐれた防水被覆剤を得ることを見い出し、本発明
に至ったものである。As a result of repeated research into waterproof coatings that take advantage of the waterproof performance of butyl rubber and have excellent adhesion to substrates, tensile strength, weather resistance, and abrasion resistance, the inventors have discovered the use of isocyanate compounds as the curing agent. The inventors have discovered that a waterproof coating having the above-mentioned properties can be obtained by doing so, and have thus arrived at the present invention.
本発明の防水被覆剤は、溶液状で直接施工面に塗布する
ことができるため、従来のようなシート施工に比較して
、格段に作業性にすぐれ、しかも、より完全な防水塗膜
が効率的に形成することができるという特徴を有する。The waterproof coating material of the present invention can be directly applied to the construction surface in solution form, so it is much easier to work with than conventional sheet construction, and moreover, a more complete waterproof coating is produced more efficiently. It has the characteristic that it can be formed in a specific manner.
本発明によれば、ブチルゴムの有機溶剤溶液を主剤とし
、これに、硬化剤としてイソシアネート化合物を使用す
ることにより1強力な防水塗膜を形成する防水被覆剤か
えられるものである。According to the present invention, a waterproof coating that forms a strong waterproof coating film is obtained by using a solution of butyl rubber in an organic solvent as the main ingredient and using an isocyanate compound as a hardening agent.
また、本発明の防水被覆主剤に天然ゴム粉末を添加する
と、塗膜の弾性を増強することができるし、また、珪砂
粉末を添加すると、塗膜の硬度を高めることができ、こ
れら配合剤は必要に応じて併用することもできる。In addition, adding natural rubber powder to the main waterproof coating material of the present invention can enhance the elasticity of the coating film, and adding silica sand powder can increase the hardness of the coating film. They can also be used together if necessary.
主剤を構成するブチルゴムは、それを溶解する有機溶剤
に溶解して溶液状にするものであり。Butyl rubber, which constitutes the main ingredient, is dissolved in an organic solvent to form a solution.
有機溶剤としては、トルエンまたはキシレンが特に好ま
しい。Particularly preferred organic solvents are toluene or xylene.
天然ゴム粉末とは常法により加硫した天然ゴムを粉末化
したものであり、その粒度は大体40メツシユ以下のも
のが塗膜の性能上好ましく、その添加率はブチルゴム溶
液に対して10〜25(重量)%が好ましく、15〜2
0%が特に好ましい。Natural rubber powder is powdered natural rubber that has been vulcanized by a conventional method, and its particle size is preferably about 40 mesh or less for the performance of the coating film, and the addition rate is 10 to 25 mesh to the butyl rubber solution. (weight)%, preferably 15-2
0% is particularly preferred.
また、珪砂粉末は270メツシユ以下の微細なものが好
適に使用され、混合割合はブチルゴム溶液に対して5〜
15%が好ましく、天然ゴム粉末と一緒に添加する場合
は、両者の添加率はブチルゴム溶液に対して25%を超
えないことが好ましい。In addition, fine silica sand powder of 270 mesh or less is preferably used, and the mixing ratio is 5 to 5 to butyl rubber solution.
15% is preferred, and when added together with natural rubber powder, it is preferred that the addition rate of both does not exceed 25% relative to the butyl rubber solution.
硬化剤としてのイソシアネート化合物は防水被覆主剤に
対して、約3〜4%の量を添加するのが好ましく、通常
、18Q缶入りの防水被覆主剤に対しては予じめ別の容
器に約540cc〜?20圓のイソシアネート化合物を
入れたものを用意しておき、工事現場にて両者を混合攪
拌し、塗布するのが便利である。It is preferable to add the isocyanate compound as a hardening agent in an amount of about 3 to 4% to the main waterproof coating material. Usually, about 540 cc of the main waterproof coating material in a 18Q can is added in advance to a separate container. ~? It is convenient to prepare a product containing 20 g of isocyanate compound, mix and stir the two at the construction site, and apply the mixture.
この際、塗膜の硬化反応は混合攪拌開始後約1時間で開
始しく気温2o℃の場合)、約3時間後には耐水性の塗
膜を形成する。At this time, the curing reaction of the coating film starts about 1 hour after the start of mixing and stirring (at a temperature of 2° C.), and a water-resistant coating film is formed after about 3 hours.
しかし、この段階ではまだ塗膜の強度が十分でなく、2
4時間後に歩行に耐える程度の強度になるが1重量物や
突起物を設置するのに十分な強度が得られるのには約5
日程度の時間が必要である。However, at this stage, the strength of the coating film was still insufficient, and 2
After 4 hours, it will be strong enough to withstand walking, but it will take about 5 hours to get enough strength to place heavy objects or protrusions.
It takes about a day.
本発明において使用するインシアネート化合物としては
、芳香族イソシアネートが好適に使用することができる
。As the incyanate compound used in the present invention, aromatic isocyanates can be suitably used.
具体的には、
ジフェニルメタンジイソシアネート
パラフェニレンジイソシアネート
クロロフェニルジイソシアネート
トルエンジイソシアネート
ナフタレンジイソシアネート
などが使用され、特に好ましくはジフェニルメタンジイ
ソシアネートが使用される。Specifically, diphenylmethane diisocyanate, p-phenylene diisocyanate, chlorophenyl diisocyanate, toluene diisocyanate, naphthalene diisocyanate, etc. are used, and diphenylmethane diisocyanate is particularly preferably used.

一般屋上防水、廊下、ベランダの防水、コンクリートや
金属の耐酸塗装、水槽などの内部塗装、化学工場の耐酸
法塗装、電気絶縁塗装、一般防錆塗装などの巾広い用途
に用いられるものであり、とくに、天然粉末ゴムを添加
した防水被覆剤を歩行面に塗布した場合は防水性とあわ
せて適度の弾性があるため、歩行者に快適な歩行性を与
えることができる。Since the waterproof coating material of the present invention has the above characteristics,
It is used for a wide range of applications such as general rooftop waterproofing, waterproofing of hallways and balconies, acid-resistant coating of concrete and metal, interior coating of water tanks, acid-resistant coating of chemical factories, electrical insulation coating, and general anti-corrosion coating. In particular, when a waterproof coating containing natural powder rubber is applied to the walking surface, it has not only waterproof properties but also appropriate elasticity, so it can provide pedestrians with a comfortable walking experience.
