METHOD FOR MANUFACTURING LAMINATE, LAMINATE, AND ASPHALT WATERPROOF LAYER WITH URETHANE WATERPROOF MATERIAL
To suppress discoloration of an urethane coating film waterproof layer, when a laminate of a primer layer and the urethane coating film waterproof layer is provided on an asphalt waterproof layer.SOLUTION: A method for manufacturing a laminate that provides a laminate on an asphalt waterproof layer has a primer layer formation step of forming a primer layer as a curable layer of a composition for primer layer formation on the asphalt waterproof layer, and an urethane coating film formation step of forming an urethane coating film waterproof layer on the primer layer, wherein the composition for primer layer formation contains a first compound E having two or more epoxy groups in a molecule and a second compound H having two or more curable functional groups capable of reacting with the epoxy groups in the molecule, and at least one of the first compound E and the second compound H has a polysulfide structure P represented by -(R10-Sx)- (wherein, R10 is a divalent or trivalent organic group, x is an integer of 1 to 5, it satisfies at least x=2, and an average value of x is more than 1 and 2.5 or less).SELECTED DRAWING: None
【課題】プライマー層とウレタン塗膜防水層の積層体をアスファルト防水層上に設けたときの、ウレタン塗膜防水層の変色を抑制する。【解決手段】アスファルト防水層上に積層体を設ける、積層体の製造方法であって、アスファルト防水層の上に、プライマー層形成用組成物の硬化層であるプライマー層を形成するプライマー層形成工程と、プライマー層の上にウレタン塗膜防水層を形成するウレタン塗膜形成工程を有し、プライマー層形成用組成物が、エポキシ基を分子内に２個以上有する第１の化合物Ｅと、エポキシ基と反応し得る硬化性官能基を分子内に２個以上有する第２の化合物Ｈとを含み、第１の化合物Ｅ及び第２の化合物Ｈの少なくとも一方が、－（Ｒ１０－Ｓｘ）－で表される（Ｒ１０は２価又は３価の有機基、ｘは１～５の整数であり、少なくともｘ＝２を含み、ｘの平均値は１超２．５以下である。）ポリサルファイド構造Ｐを有する、積層体の製造方法。【選択図】なし
