Abstract

The invention discloses a preparation method of a nano zinc oxide-biomass fiber composite material, and belongs to the technical field of inorganic material processing. The method comprises the following steps of (1) nano zinc oxide pretreatment; (2) biomass fiber pretreatment; (3) steam explosion treatment; (4) corona treatment; and (5) cold plasma treatment. According to the preparation method of the nano zinc oxide-biomass fiber composite material, nano zinc oxide and biomass raw materials are treated and effectively combined, so that the finally prepared nano zinc oxide-biomass fiber composite material cannot be agglomerated when being combined with a high polymer, is excellent in dispersity, has good filling characteristics, and can be used for processing and preparation of plastics,castings, rubber and the like to improve the quality of processed products.

Description

technical field [0001] The invention belongs to the technical field of inorganic material processing, and in particular relates to a preparation method of nanometer zinc oxide-biomass fiber composite material. Background technique [0002] As a high-performance semiconductor material, nano-zinc oxide has unique small size effect, surface effect, quantum size effect, macroscopic quantum tunneling effect and dielectric confinement effect, so it is widely used in antibacterial materials, luminescent materials, piezoelectric materials, ultraviolet Shielding materials, self-cleaning materials, cell calibration materials, and nano-catalysts have a wide range of application prospects, but when nano-zinc oxide is directly used as a filler component and mixed with polymers, agglomeration will occur, and it will also be affected by interfacial effects. resulting in poor filling effect. [0003] Biomass fibers can be basically divided into three categories: biomass primary fibers, bio...
