Abstract

The invention provides a preparation method of full ocean depth hollow glass micro-beads, wherein the preparation method comprises the steps: mixing raw materials of SiO2, Na2O, CaO, B2O3, K2O or Li2O, BaO or MgO and Al2O3 evenly; putting the raw materials into a melting furnace, melting, pouring the prepared molten glass into a water quenching tank, and carrying out water quenching; drying the obtained glass, and then carrying out powder grinding classification into a glass powder through a gas flow crushing classifier; carrying out hollow balling of the glass powder by a bead forming furnace; separating the collected material to obtain hollow glass micro-beads through a flotation method; carrying out suppressing optimization of the hollow glass micro-beads; then carrying out primary winnowing of the hollow glass micro-beads, allowing the winnowed hollow glass micro-beads to enter an ultrasound vibration classifier, carrying out particle size classification, and thus obtaining the full ocean depth hollow glass micro-beads. The invention provides the full ocean depth hollow glass micro-beads prepared by the preparation method of the full ocean depth hollow glass micro-beads. The hollow glass micro-beads prepared by the preparation method have the particle size centralized at 5-45 [mu]m, have the density of 0.46+ / -0.02 g / cm<3>, the compressive strength of more than or equal to 110 MPa and the floating rate of more than or equal to 99%, have high rate of finished products, and are easy to melt.

Description

technical field [0001] The invention relates to an inorganic filler, in particular to a hollow glass microsphere for full sea depth. [0002] The invention also relates to a preparation method of the hollow glass microsphere for deep sea use. Background technique [0003] Full-sea deep solid buoyancy material (11,000 meters) is an important equipment for full-sea deep submersibles. It has the characteristics of low density, high mechanical properties, and excellent hydrostatic pressure performance. It can be applied to full-sea deep ROVs, full-sea deep AUVs, In the deep sea HOV, it is an important safety guarantee and buoyancy guarantee for the deep sea submersible to successfully complete tasks such as resource exploration and scientific data collection. The ultra-fine super-strong hollow glass microspheres are the core component materials for the preparation of full-sea deep buoyancy materials. However, the current hollow glass microspheres have the disadvantages of low ...
