The invention provides a yellowed-resistance type transparent urethane elastomer combination material, wherein the polyatomic alcohol part comprises 3 functionality and 4000-6000 molecular weight polyether polyol, 2 functionality and 2000-4000 molecular weight polyether polyol, aromatic, chain expansion agent and accelerant; the prepolymer part (NCO%=12%-17%)is made by 1000-2000 molecular weight, 2 functionality polyether polyol and isophorone diisocyanate at 70-90Deg. The use method comprises the following steps: mixing prepolymer with polyatomic alcohol part according to 2:1-1:1 at 25Deg.C-40Deg. C, pouring; vulcanizing at 25Deg. C-70Deg. C. The product avoids the low yellowed resistance problem of the urethane elastomer product, which is used to manufacture the armoured glass, the neon sign board, the shoe sign and the nameplate of the household electrical appliance.
