METHOD FOR MANUFACTURING COMPOSITE BODY AND COMPOSITE BODY, METHOD FOR MANUFACTURING COATED METAL PLATE AND COATED METAL PLATE

To provide a method for manufacturing a composite body which hardly causes blocking in a manufacturing process and has good adhesion.SOLUTION: A method for manufacturing a composite body includes: a step 1) of mixing a curable resin 2, a curing agent and carbon-based particles 3 having a DBP oil absorption amount of 100 ml/100 g or more of an aggregate, and obtaining a primer composition which has a content of the carbon-based particles of 3-25 mass% with respect to the curable resin and does not substantially contain a rubber component 6; a step 2) of adding a primer composition onto a metal plate, then curing the primer composition, and forming a primer layer; and a step 3) of adding a rubber composition containing a rubbery polymer and a crosslinking agent onto the primer layer, then crosslinking the primer layer, and forming a rubber layer.SELECTED DRAWING: Figure 1 【課題】製造過程でブロッキングを生じにくく、良好な接着性を有する複合体の製造方法の提供。【解決手段】１）硬化性樹脂２と、硬化剤と、凝集体のＤＢＰ吸油量が１００ｍｌ／１００ｇ以上であるカーボン系粒子３とを混合して、カーボン系粒子の含有量が、硬化性樹脂に対して３〜２５質量％であり、かつゴム成分６を実質的に含まないプライマー組成物を得る工程と、２）プライマー組成物を金属板上に付与した後、硬化させて、プライマー層を形成する工程と、３）プライマー層上に、ゴム系重合体と、架橋剤とを含むゴム組成物を付与した後、架橋させて、ゴム層を形成する工程と、を有する複合体の製造方法。【選択図】図１
