Abstract

The invention aims at providing an efficient antibacterial masterbatch. The method is characterized in that porous bentonite powder is selected as an antibacterial agent carrier and is modified to carry negative charges through a quaternary ammonium base solution, and then the processed porous bentonite powder is soaked in a resin solution with opposite charge; the surface layer of the porous bentonite powder is covered by a resin film under the mutual effect of charge; a solvent is removed; the product is dried and crushed to obtain the efficient antibacterial masterbatch. According to the efficient antibacterial masterbatch and the preparation method, the surface of an inorganic carrier is covered by the film, so that the technical problem of non-uniform dispersing of an current inorganic antibacterial agent in resin can be solved, and the antibacterial effect is improved.

Description

technical field [0001] The invention belongs to the field of composite materials and functional polymer materials, and in particular relates to an efficient antibacterial masterbatch. Background technique [0002] Antibacterial materials are a new class of functional materials with antibacterial and bactericidal properties. It is often made by adding or compounding one or several specific antibacterial ingredients (antibacterial agents) to common materials, such as antibacterial plastics, antibacterial synthetic fibers, and antibacterial ceramics. After ordinary materials are endowed with antibacterial properties, various products made of them have hygienic and self-cleaning functions, which can play an important role in protecting human health and reducing diseases. Antibacterial plastics and antibacterial fibers, as the most striking branches of antibacterial materials, are used in a wide range of fields and have important research and application values. Among them, the...
