Problems solved by technology

Usually, when wearing a mask, a large amount of water vapor will be generated, which will affect the electrostatic adsorption performance of meltblown nonwovens
[0007] Melt blown non-woven fabric is a filter material made of polypropylene as the main raw material, which has a certain protective effect on dust particles and smog. However, it has poor ability to kill and inhibit viruses and bacteria with a diameter of 2 to 5 microns. Therefore, Directly affect the protective effect of the mask

Abstract

The invention discloses nanometer polypropylene slices and a preparation method thereof, belonging to the technical field of new material processing. The preparation method comprises the following steps: with three nano-powder materials, namely nano-scale silicon dioxide, nano-scale titanium dioxide and nano-scale graphene, as main bodies, mixing the three nano-powder materials so as to prepare anovel nano-powder material, fully mixing the novel nano-powder material with conventional polypropylene slices, and preparing the nano-polypropylene slices through a granulator. The nano-polypropyleneslices provided by the invention have super-strong physical adsorption and chemical adsorption effects, so the super-efficient filtering function and super-strong sterilization and bacteriostasis functions of a product are realized.

Description

technical field [0001] The invention belongs to the technical field of new material processing, and in particular relates to a nano-polypropylene slice and a preparation method thereof. Background technique [0002] Air pollutants are ubiquitous in the environment. Pollutants include a variety of airborne respiratory infectious diseases and emerging diseases. In highly polluted areas, aerosols become the main air pollutants, that is, solid or liquid suspended particles in the gas. [0003] The hazards of air pollutants can be managed through the use of basic control measures, such as increased ventilation or providing workers with protective equipment such as protective masks, to keep harmful viruses in the air and prevent the spread of viral bacteria. [0004] Protective face masks are widely used by hospital workers, laboratory researchers, construction workers, and the general public in high-pollution areas, during flu season, or during an emerging disease. [0005] Mos...
