RESIN FILLER AND REPAIRING METHOD USING THE SAME
To provide a resin filler which is made of a urethane foam resin excellent in toughness and is hardly crushable or is fracture-resistant even when a large load acts thereon, and to provide a repairing method using the resin filler.SOLUTION: A resin filler of the present invention is used for filling a cavity under a plate-like body and is made of a urethane foam resin having a bulk density of 0.20 to 0.40 g/cm3, a uniaxial compressive strength of 2500 to 9100kN/m2, and a deformation coefficient of 100 to 320 MN/m2. The urethane foam resin more preferably has densities of 0.225 to 0.30 g/cm3, uniaxial compressive strengths of 3000 to 5300kN/m2, and deformation coefficients of 120 to 200 MN/m2.SELECTED DRAWING: Figure 2
【課題】靭性に優れた発泡ウレタン樹脂からなり、大荷重が作用しても破砕あるいは破断し難い樹脂充填材および当該樹脂充填材を用いた補修方法を提供する。【解決手段】本発明の樹脂充填材は、版状体の下の空洞に充填するために用いられる樹脂充填材であって、密度が０．２０～０．４０ｇ／ｃｍ３であり、一軸圧縮強さが２５００～９１００ｋＮ／ｍ２であり、変形係数が１００～３２０ＭＮ／ｍ２である発泡ウレタン樹脂からなる。発泡ウレタン樹脂は、密度が０．２２５～０．３０ｇ／ｃｍ３であり、一軸圧縮強さが３０００～５３００ｋＮ／ｍ２であり、変形係数が１２０～２００ＭＮ／ｍ２であることがより好ましい。【選択図】図２
