Description
含む防水層の表面処理剤に関する。また、本発明は、前記テルペンが、単環性のモノテルペンである、前記表面処理剤に関する。
(式中、点線部分は、二重結合となっていても良い箇所を示す。)で表される単環性テルペンの少なくとも1種である、前記面処理剤に関する。
[表面処理剤]
本発明の表面処理剤は、テルペンを含有することを特徴とする。
(式中、点線部分は、二重結合となっていても良い箇所を示す。ただし、隣接した点線部分は、その両方が同時に二重結合にはならない。)で表される単環性テルペンの少なくとも1種を使用することが好ましい。さらに、入手の容易性を考慮すると、メンタン、フェランドレン、シメン、テルピノレン、リモネン、ジペンテン、α−ピネン、β−ピネンの少なくとも1種、とりわけリモネン(特にd体)の使用が好ましい。
[防水層の補修方法]
本発明の表面処理剤を用いた既設のFRP防水層の補修方法を手順に沿って説明する。
を目的として、適宜トップコート層が形成されていてもよい。このようなトップコート層としては、アクリル、フッ素、ウレタン樹脂などがあげられる。
ン系、変成シリコーン系、アクリルウレタン系の防水材が好ましい。
d−リモネンを表面処理剤として用い、「付着性試験」を行った。
d−リモネンと乳酸エチルを重量比で50:50とした混合物を表面処理剤として用い、「付着性試験」を行った。
表1に示す各有機溶剤を表面処理剤として用い、「付着性試験」を行った。
表面処理剤を用いずに「付着性試験」を行った。
木製の板の上に厚さ1mmで施工したFRP防水層(日本特殊塗料社製、タフシール)を5年間屋外で暴露した後に2mm×2mmに切り出したものを被着体とした。
PF:プライマーと被着体の界面剥離
*1:カクタスソルベントP−20(ジャパンエナジー社製)
*2:エクゾールD40(エクソンモービル社製)
