AI Technical Summary

Problems solved by technology

Due to the filter media and the material of the filter material itself, these filter elements are easily polluted and breed bacteria and algae
In addition, traditional filter materials have very limited filtering effects on submicron particles. If the electrostatic adsorption between materials and particles is enhanced during the filtration process, charged particles or induced neutral particles can be polarized and then capture, so that while enhancing filtration efficiency, breathing resistance does not increase

Abstract

The invention discloses a multifunctional melt-blown filter element which is prepared from the following raw materials in parts by weight: 90-95 parts of PP resin, 1-5 parts of electret master batch, 1-5 parts of an antibacterial agent, 1-5 parts of a compatilizer and 1-3 parts of a dispersing agent. The electret master batch is prepared from the following raw materials in parts by weight: 70-80 parts of homo-polypropylene resin; 1-3 parts of tourmaline powder; 1-3 parts of nano silicon dioxide; 5-10 parts of polypropylene grafted maleic anhydride; 5-10 parts of dibenzylidene sorbitol; and 5-10 parts of erucyl amide. The prepared multifunctional melt-blown filter element has excellent filtering efficiency and antibacterial and mildew-proof properties.

Description

technical field [0001] The invention belongs to the technical field of melt-blown filter cores, and in particular relates to a multifunctional melt-blown filter core and a preparation process thereof. Background technique [0002] Melt-blown nonwovens are a manufacturing method that obtains extremely fine fibers by direct drawing, and forms a three-dimensional labyrinth structure by self-fusion and entanglement. Compared with nonwovens carded into a web by traditional weaving methods, it has a larger ratio Surface, higher porosity and finer pore size, its excellent filterability is better than ordinary filter materials. At present, melt-blown nonwovens can be designed into a variety of filter materials in the form of filter cloth, cylindrical filter elements, filter bags, etc., for the filtration industry. [0003] But at present, the function of various forms of filter materials is only to filter, which often cannot meet the requirements of use, especially the filter eleme...
