1. A reinforcing material for rubber comprising amorphous aluminosilicate particles, wherein the aluminosilicate particles are represented by following Chemical Formula 1:
[(MaAlxO2x).(SiyO2y)].m(H2O)  [Chemical Formula 1]
wherein, in Chemical Formula 1,
M is an element selected from the group consisting of Li, Na, K, Rb, Cs, Be, Fr, Ca, Zn, and Mg, or an ion thereof;
a≥0, x>0, y>0, and m≥0;
a/x<1.2; and
3.0<y/x<20.0, and
wherein the aluminosilicate particles satisfy the following conditions:
in a data plot obtained by X-ray diffraction (XRD) of the aluminosilicate particles, a full width at half maximum (FWHM) in a 2θ range of 23° to 37° is 5° to 7° , and a maximum peak intensity (Imax) is in a 2θ range of 23° or more and 25.8° or less, and
wherein a secondary particle size distribution of the aluminosilicate particles has a volume average particle diameter (Dmean)of 1 to 25 μm, a geometric standard deviation of 1 to 20 μm, and a 90% cumulative particle diameter (D90) of 1 to 50 μm, when measured using distilled water.
