Modified hollow glass bead as well as preparation method and application thereof

The invention relates to a modified hollow glass bead as well as a preparation method and application thereof, and belongs to the technical field of plastic products. The modification method comprises the following steps: soaking hollow glass beads in a composite emulsion, carrying out solid-liquid separation, and then carrying out drying treatment, the composite emulsion is formed by mixing a sulfur-containing silane coupling agent into a rubber emulsion. According to the preparation method of the modified hollow glass beads, the sulfur-containing silane coupling agent is added into the rubber emulsion, so that the bonding strength between a coating layer formed after modification and the hollow glass beads can be enhanced; when the modified hollow glass beads are heated, the sulfur element in the sulfur-containing silane coupling agent promotes partial vulcanization crosslinking of the latex on the surfaces of the hollow glass beads, so that the binding property and the elastic property of the hollow glass
