Abstract

The invention provides a multifunctional opening foaming polymer particle and a preparation method thereof. The method includes the steps that nano-titanium dioxide or nano-zinc oxide or nano silver powder or nano zinc sulfide is used as a multifunctional auxiliary, an appropriate coupling agent, polymeric dispersant, antioxygen and polymer resin are further adopted, a twin-screw extruder is used for achieving melt blending to conduct extrusion and particle cutting, functional nano powder is wrapped in matrix resin so that polymer particles can be formed, then the polymer particles are foamed by supercritical carbon dioxide gas, the multifunctional opening foaming polymer particle with excellent performance can be prepared, the particle has a surface opening through hole structure and an inner continuous large hole structure, the particle size is 0.5-5 mm, and the opening hole diameter and the inner through hole diameter of the surface of a particle spherical shell both can reach 50 nm-10 microns. The preparation method is simple in technology, convenient and easy to implement. The prepared opening foaming polymer particle has the functions of absorption, filtering, antibacteria and mold prevention, catalysis, odor removal, formaldehyde removal, anti-ultraviolet ageing and the like.

Description

technical field [0001] The invention relates to an open-cell foamed polymer particle and a preparation method thereof, in particular to a multifunctional open-cell foamed polymer particle and a preparation method thereof. Background technique [0002] As an excellent adsorbent, activated carbon is widely used in waste gas and harmful gas treatment, gas purification, water purification, sewage treatment, disinfection and deodorization, etc. However, because activated carbon only physically adsorbs impurities, it is effective in a short period of time, and the effect will become significantly worse after a long time. When a certain amount of impurities are adsorbed, it will easily reach a saturated state and no longer have any effect. Especially when activated carbon absorbs odors, the odors adsorbed earlier will also be released while adsorbing, especially when the light or temperature rises, the release will be more obvious, which is an inevitable defect of using activated c...
