To provide a rubber member improved in flame retardancy and normal-state physical properties of rubber such as modulus and tensile strength in a well-balanced manner.SOLUTION: The rubber member is provided with a coating layer on at least one surface. The coating layer contains an intumescent type phosphate as a flame retardant. A rubber component constituting the rubber member is preferably a natural rubber. When the total weight of the coating layer is 100 wt.%, the phosphate is preferably contained in an amount of 15-50 wt.%.SELECTED DRAWING: None
【課題】難燃性と、モジュラスや引張強度などのゴム常態物性とをバランス良く向上したゴム部材を提供すること。【解決手段】少なくとも一方の面にコーティング層を備えるゴム部材であって、コーティング層が、難燃剤としてイントメッセント系のリン酸塩を含有するゴム部材。ゴム部材を構成するゴム成分は、天然ゴムであることが好ましく、コーティング層の全重量を100重量%としたとき、リン酸塩を15〜50重量%含有することが好ましい。【選択図】 なし
