Abstract

The invention discloses an antibacterial PP melt-blown material and a melt-blown filter element, and relates to the technical field of filter elements. The antibacterial PP melt-blown material is prepared from the following components in percentage by mass: 90 to 96 percent of PP resin; 1%-4% of an antibacterial agent; 2%-4% of a compatilizer and 0.2-2% of a dispersing agent; the antibacterial agent is polyhexamethylene guanidine; the antibacterial PP melt-blown filter element is prepared from the antibacterial PP melt-blown material. The antibacterial PP melt-blown material is prepared by adding the antibacterial agent polyhexamethylene guanidine, the antibacterial PP melt-blown filter element is prepared from the antibacterial PP melt-blown material, the long-acting antibacterial effectof the filter element is achieved, and the problems that an existing filter element is poor in stability and low in sterilization efficiency are solved.

Description

technical field [0001] The invention belongs to the technical field of filter cores, and in particular relates to an antibacterial PP melt-blown material, a melt-blown filter core and a preparation method thereof. Background technique [0002] Water purifiers, also called water purifiers and water purifiers, are water treatment equipment that perform deep filtration and purification of water quality according to the requirements for water use. The water purifier that people usually talk about generally refers to a small purifier for household use. The water purifier is an indispensable household appliance in our daily family. It is generally connected behind the water outlet of the tap water to provide filtration protection for human drinking water and kitchen electricity. [0003] In addition, with the improvement of people's living standards, the functional requirements of water purifiers are getting higher and higher, especially the sterilization function of water purifi...
