| description | To provide negative thermal expansion fine particles which have good affinity and compatibility with a positive thermal expansion material, and have good dispersibility in the positive thermal expansion material, and a method for producing the same.SOLUTION: Negative thermal expansion fine particles have a negative thermal expansion material 14 having a negative thermal expansion coefficient, and a polymerizable component 12 including the negative thermal expansion material. The polymerizable component contains an epoxy ester-based resin or an urethane resin, a weight ratio A/B of the polymerizable component to the negative thermal expansion material is 90/10 to 25/75, and a volume average particle diameter D is 1-50 μm. The polymerizable component contains an epoxy ester-based resin formed of an epoxy ester methacrylic acid adduct (epoxy ester methacrylate) or an epoxy ester acrylic acid adduct (epoxy ester acrylate). The polymerizable component contains a urethane resin formed of isocyanurate type polyisocyanate or an isocyanurate type polyisocyanate prepolymer.SELECTED DRAWING: Figure 1
【課題】正熱膨張材料との親和性、相溶性が良く、正熱膨張材料内において良好な分散性を有する負熱膨張微粒子、及びその製造方法を提供する。【解決手段】負の熱膨張係数を有する負熱膨張材料１４と前記負熱膨張材料を内部に包含する重合性成分１２とを有し、前記重合性成分はエポキシエステル系樹脂又はウレタン樹脂を含み、前記重合性成分と前記負熱膨張材料の重量比はＡ／Ｂ：９０／１０〜２５／７５であり、体積平均粒子径がＤ：１〜５０μｍである。前記重合性成分は、エポキシエステルメタクリル酸付加物（エポキシエステルメタクリレート）、又は、エポキシエステルアクリル酸付加物（エポキシエステルアクリレート）によって形成されたエポキシエステル系樹脂を含む。前記重合性成分は、イソシヌレート型ポリイソシアネート又はイソシヌレート型ポリイソシアネートプレポリマーによって形成されたウレタン樹脂を含む。【選択図】図１ |
