Abstract

The invention discloses ultrafiltration embossed melt-blown non-woven fabric and a preparation method thereof. The ultrafiltration embossed melt-blown non-woven fabric is prepared from a melt-blown non-woven fabric composite slice material; and the melt-blown non-woven fabric composite slice material is prepared from the following raw materials in parts by weight: 65-80 parts of polypropylene melt-blown non-woven fabric slices, 24-36 parts of poly(dimethylsiloxane)-grafted-polyacrylate, 5-8 parts of maleic anhydride styrene dimonomer grafted polypropylene, 4.5-6 parts of nano titanium dioxide,3-5 parts of mesoporous silicon dioxide, 2.4-3 parts of stearyl phthalamide and 1.5-2 parts of zinc stearate. The ultrafiltration embossed melt-blown non-woven fabric is prepared from the melt-blownnon-woven fabric composite slice material, and the melt-blown non-woven fabric composite slice material can be normally produced through an existing melt-blown non-woven fabric machine; and the produced ultrafiltration embossed melt-blown non-woven fabric is excellent in filtering performance, moderate in gram weight, high in tensile strength and good in softness.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to an ultra-filtration embossed melt-blown non-woven fabric and a preparation method thereof. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Non-woven fabrics have no warp and weft threads, are very convenient for cutting and sewing, and are light in weight and easy to shape, so they are deeply loved by handicraft lovers. Because it is a fabric that does not need spinning and weaving, it is just oriented or random arrangement of short textile fibers or filaments to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. [0003] Non-woven fabric is a kind of non-woven fabric. It directly uses polymer chips, short fibers or filaments to form fibers through airflow or machinery, and then und...
