The invention provides an aluminum hydroxide modified glass bead as well as a preparation method and application thereof. The aluminum hydroxide modified glass bead comprises a hollow glass bead and an aluminum hydroxide coating layer formed on the surface of the hollow glass bead through an in-situ synthesis method. The preparation method comprises the following steps: uniformly mixing hollow glass beads, a soluble aluminum salt solution and ammonia water, enabling soluble aluminum salt to react with the ammonia water, and forming an aluminum hydroxide coating layer on the surfaces of the hollow glass beads. Therefore, the aluminum hydroxide modified glass bead enables the hollow bead to have flame retardant property, and when the aluminum hydroxide modified glass bead is applied to a flammable polymer material, the candlewick effect of the flammable polymer material during combustion can be avoided, the flame retardant property of the polymer material is improved, and the density of the polymer material is
