Abstract

The invention provides a graphene antibacterial mask filter material and a preparation method and application thereof. According to the method, antibacterial primary masterbatches are prepared by a method for producing masterbatches through ingredient mixing by a double-screw extruder; and agglomeration of graphene nanosheets is effectively weakened by a melt-blowing process. A macro-structure with certain morphology is formed by graphene through superposition or overlapping of sheet layers. After macroscopic fibers are assembled by the graphene, the structural strength of the material is enhanced, furthermore, an effect of a flexible supporting body is achieved between graphene sheet layer structures, aggregation of graphene sheet layers is relieved, and mechanical properties, high thermal conductivity, high-speed electron mobility and good adsorption capacity of the graphene are played well, and the prepared material has excellent antibacterial effect and wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of filter masks, and in particular relates to a graphene antibacterial mask filter material and a preparation method and application thereof. Background technique [0002] After the industrial revolution, the rapid development of industry, population and cities has produced increasingly serious pollution of air, water and soil. Various pollutants formed in industrial production and daily life have caused problems such as the deterioration of the ecological environment and the decline in the quality of life. These pollutants include toxic gases and particulate matter, heavy metals, organic matter and biohazardous substances. Aiming at these pollutants, various physical, chemical and biological techniques have been successfully developed to deal with them. Among them, the adsorption method is widely used in the control of pollutants due to its simplicity, ease of operation and high efficiency. Moreover, the...
