Embodiment 1

[0034] S1. 25 grams of 3s non-woven fabric (the material is polypropylene, the same below) is ultrasonically cleaned with petroleum ether, absolute ethanol, and deionized water for 1 hour, and then dried in a 60°C drying oven to obtain a pretreated non-woven fabric. cloth.

[0035] S2. Take hexamethylenetetramine ethanol solution, drop zinc nitrate ethanol solution into it at a speed of about 2 drops / second, stir while adding, and continue stirring for 5 minutes after the dropwise addition to obtain hexamethylenetetramine Hexamethylenetetramine / zinc nitrate mixed ethanol solution with concentration of 0.05mol / L and zinc nitrate concentration of 0.05mol / L. Immerse the pretreated non-woven fabric in the above-mentioned hexamethylenetetramine / zinc nitrate mixed ethanol solution, place it in a drying oven at 95°C and heat it for 4 hours, take out the non-woven fabric from the solution after heating, and rinse it repeatedly with deionized water. Place it in a drying oven at 60°C a...

Abstract

The invention belongs to the field of materials, and relates to a super-hydrophobic antibacterial non-woven fabric, a mask and a preparation method and application of the super-hydrophobic antibacterial non-woven fabric. The preparation method of the super-hydrophobic antibacterial non-woven fabric comprises the steps that S1, the non-woven fabric is ultrasonically cleaned with petroleum ether, absolute ethyl alcohol and deionized water in sequence and then dried to obtain pretreated non-woven fabric; S2, the pretreated non-woven fabric is soaked into a mixed ethanol solution of hexamethylenetetramine and zinc nitrate, heating is carried out for 2-6 hours at 90-100 DEG C, then the non-woven fabric is taken out from the solution, and the pretreated non-woven fabric is repeatedly washed withdeionized water and dried; and S3, the step S2 is repeated for 1-5 times to obtain the super-hydrophobic antibacterial non-woven fabric. The obtained super-hydrophobic antibacterial non-woven fabrichas excellent super-hydrophobic performance and antibacterial performance, can be washed with water and recycled, and has a wide application prospect.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a superhydrophobic antibacterial non-woven fabric, a mask and a preparation method and application thereof. Background technique [0002] In recent years, people's awareness of safe production and respiratory protection has increased, and they have been hit by the epidemic. During the Spring Festival in 2020, it has become a situation of "hard to find one mask". Existing disposable masks usually include two layers of ordinary non-woven fabrics and a layer of meltblown fabric placed in the middle of the nonwoven fabric. The filtering effect of the mask mainly comes from the barrier of harmful substances by the meltblown fabric, while the nonwoven fabric on both sides The layer can only play the role of blocking large particles. Compared with other cloth masks, the existing disposable masks cannot be cleaned, because the melt-blown cloth mainly relies on electrostatic adsorpti...
