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、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。 The butyl rubber constituting the main ingredient is dissolved in an organic solvent to form a solution, and the organic solvent is particularly preferably toluene or xylene.
天然ゴム粉末とは、常法により加硫した天然ゴ

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 preferably 5 to 15% with respect to the butyl rubber solution.When added together with natural rubber powder, the addition ratio of both is Preferably it does not exceed 25% of the 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、18缶入りの防水被覆主剤に対

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, for 18 cans of the main waterproof coating material, about 540 c It is convenient to prepare a product containing an isocyanate compound of .c. to 720 c.c., mix and stir the two, and apply the mixture at the construction site.
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（気温20℃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 takes about 1 hour after the start of mixing and stirring.
The process starts within an hour (at a temperature of 20°C) and forms a water-resistant coating 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、24時間後に歩行に耐える程度の強度になる
が、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 paint film is still not strong enough, and it will be strong enough to withstand walking after 24 hours, but it will take about 5 days for it to be strong enough to install heavy objects or protrusions. It takes some time.
本発明において使用するイソシアネート化合物
としては、芳香族イソシアネートが好適に使用す
