Aromatic melt-blown non-woven fabric having low ventilation resistance, planar mask with melt-blown non-woven fabric and manufacturing method of planar mask

Abstract

The invention discloses an aromatic melt-blown non-woven fabric having low ventilation resistance, a planar mask with the melt-blown non-woven fabric and a manufacturing method of the planar mask. Theplanar mask is prepared from the following raw materials in parts by weight of 80-90 parts of polypropylene melt-blown non-woven fabric slices, 10-13 parts of maleic anhydride grafted polypropylene,5-7 parts of metallocene catalyzed linear low-density polyethylene, 1.8-2.2 parts of mesoporous silica, 2.5-3 parts of nano bismuth stearate, 1.5-1.8 parts of 3-[3-(benzotriazole-2-yl)-5-tert-butyl-4-hydroxyphenyl] methyl propionate, 3-3.8 parts of 2,6-dimethylphenylphthalimide, 2-2.5 parts of oleamide and 0.6-0.9 part of erucamide. The aromatic melt-blown non-woven fabric having low ventilation resistance is good in filtering effect and excellent in electret charge storage performance, the filtering efficiency of the non-woven fabric is still good after the non-woven fabric is stored for 3 months under the high-temperature and high-humidity conditions, and the prepared planar mask is good in filtering effect and good in protection effect. The mask is good in air permeability, low in ventilation resistance, and not liable to cause discomfort such as oxygen deficit when being worn.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics and masks, in particular to an aromatic melt-blown non-woven fabric with low ventilation resistance, a flat mask with the melt-blown non-woven fabric and a manufacturing method thereof. Background technique [0002] Masks are health care products commonly used in people's daily life. Most of the masks commonly used at the beginning are made of gauze, fine cloth or ordinary non-woven fabrics. These masks generally only function to isolate dust, impurities and fiber substances in the air. Enter the mouth and nasal cavity. The raging SARS in 2003, the widespread spread of bird flu and various respiratory infectious diseases in recent years, and the recent outbreak of new coronavirus pneumonia have brought serious threats to human health. These diseases are transmitted through the air. An important protective measure to prevent these diseases is to wear a mask. However, ordinary dust masks...

AI Technical Summary

Problems solved by technology

[0005] 1. The melt-blown non-woven fabric used has poor filtering effect, and the prepared flat mask has poor filtering effect and poor protection effect;

[0006] 2. The melt-blown non-woven fabric used has poor air permeability and large ventilation resistance, and it is easy to cause discomfort such as hypoxia when worn;

[0007] 3. The antibacterial and deodorizing effect of the flat mask is poor, which leads to the easy breeding of bacteria during use, causing secondary harm, and the protective effect is greatly reduced;

[0008] 4. Flat masks are irritating and even toxic to human skin and other biological skins, and have poor sweat absorption, moisture drainage, and air permeability, which can easily lead to skin allergies and other symptoms
