Problems solved by technology

However, due to the low glass transition temperature of polystyrene, about 90-100°C, it is easy to deform and lose its hollow structure under high temperature and high pressure, so its use in high temperature and high pressure environments is limited, such as the ability to resist temperature and pressure. Required drilling fluid, cementing fluid, etc.

Abstract

The invention provides a preparation method for a plastic hollow globule and the prepared plastic hollow globule and application thereof. The preparation method comprises the following steps: dissolving an oil phase solute in an organic solvent to obtain an oil phase, wherein the oil phase solute is polycarbonate or a mixture of polystyrene and / or a styrene monomer and polycarbonate; adding an emulsifier into water to obtain a first water phase; adding a dispersant or a mixture of the dispersant and the emulsifier into water to obtain a second water phase; fully emulsifying the oil phase and the first water phase to prepare a first emulsion; adding the second water phase into the first emulsion for complete emulsification so as to obtain a second emulsion and heating the second emulsion to allow the organic solvent to evaporate and an oil phase liquid drop to be cured and foamed; and carrying out liquid-solid separation, separating out a solid phase and drying the solid phase to prepare the plastic hollow globule with a hollow structure inside and an average particle size of 1 to 300 mu. The plastic hollow globule has a small and controllable particle size and can be used in fields like oil drilling fluids, cosmetics and paints.

Description

technical field [0001] The invention relates to the field of plastic processing, and more specifically, relates to a method for preparing hollow plastic pellets, products prepared by the same and applications thereof. Background technique [0002] Hollow microsphere materials have unique chemical and physical properties due to their special hollow structure. In recent years, they have attracted more and more attention and become a research hotspot in the field of materials. So far, inorganic materials, polymer materials, metal oxide materials and semiconductor materials (gallium oxide, gallium nitride) have all been tried to be prepared into hollow microsphere materials by domestic and foreign researchers. Different special features for solid materials. These hollow microsphere materials with special characteristics are expected to be used in microreactors, drug delivery, controlled release, photocatalysis, enzyme coating, photonic crystals, etc. In addition, due to the lo...
