PROBLEM TO BE SOLVED: To provide an adhesive for a rubber with fiber, having a high dispersion stability and a good adhesive property even by using a small applied amount, a synthetic fiber for reinforcing the rubber capable of maintaining the original characteristics of the synthetic fiber and a high adhesive property, and a fiber-reinforced rubber structural material reinforced by using the above synthetic fiber. SOLUTION: This adhesive composition is characterized by blending the adhesive matrix component with fine particles of silisic acid salt compound containing silicon, aluminum and magnesium as main constituting elements, having 1/(0.1-1.0) molar ratio of silicon/aluminum, 1/(0.01-0.1) molar ratio of silicon/magnesium, 10/(1-4) molar ratio of aluminum/magnesium and >=5 wt.% aluminum content, and being adsorbed with a polymer having an ionic functional group. |
