Functional agglomerated stone capable of releasing negative ions and preparation method of functional agglomerated stone

The invention discloses functional agglomerated stone capable of releasing negative ions. The functional agglomerated stone is prepared from the following raw materials in parts by weight: 6-8 parts of resin powder, 7-10 parts of a curing agent, 0-2.5 parts of an accelerant, 20-30 parts of a powder material, 20-30 parts of a sand material and 0.1-1 part of a modified tourmaline material. The invention also discloses a preparation method of the functional agglomerated stone. The preparation method comprises the following steps: S1, mixing and stirring the above raw materials in proportion to obtain a material A; and S2, pouring the material A into a mold, carrying out vacuum oscillation for 1-2 minutes, and performing natural curing to obtain the functional agglomerated stone. The functional agglomerated stone is high in hardness and strength; the modified tourmaline material is added, so micro-current basically matched with bioelectricity of a human body always flows on the surface of the agglomerated stone,
