preparation example Construction

[0023] The preparation method of the antibacterial layer includes the following steps:

[0024] (1) Preparation of finishing liquid: take 10-15 parts by weight of polymer emulsion, 1-10 parts by weight of guanidine salt, and 60-70 parts by weight of water and stir to obtain finishing liquid;

[0025] (2) Immerse the fabric in the finishing solution at a bath ratio of 1: (40-60) (g / mL) for 60-70 minutes, one dipping and one rolling, with a margin of 70-80%, and then take the fabric out and dry it. Immediately.

[0026] The preparation method of the polymer emulsion includes the following steps: heating 40 parts by weight of PEG1000 to 110°C, vacuuming for 2 hours, reducing the temperature to 50°C, adding 20 parts by weight of 1,6-hexamethylene diisocyanate, 1 Parts by weight of 1,4-butanediol were reacted at 70°C for 4 hours, and then 2 parts by weight of C10-C18 alkylamine and 0.5 parts by weight of dibutyltin dilaurate were added, and reacted for 2 hours to obtain a polymer emulsio...

Embodiment 1

[0035] An antibacterial and antiviral mask, comprising a mask body. The mask body includes a fiber inner layer, a bacteriostatic layer, and a protective layer from the inside to the outside. The fiber inner layer and the bacteriostatic layer, the bacteriostatic layer and the protective layer pass through the entire The automatic flat mask is sliced ​​into the mask body.

[0036] The fiber inner layer is made of bamboo fiber and cotton fiber; the weight ratio of the cotton fiber to the bamboo fiber is 1:1; the specific preparation method of the fiber inner layer is: adding cotton fiber and bamboo fiber into water, After being evenly stirred, it is spread into a net by a netting machine, and then spunlaced once, and sprayed with 100Bar water pressure.

[0037] The protective layer is a medical non-woven fabric, which is a commercial product.

[0038] The preparation method of the antibacterial layer includes the following steps:

[0039] (1) Preparation of finishing liquid: take 12 par...

Embodiment 2

[0044] An antibacterial and antiviral mask, the specific implementation is the same as in Example 1, the difference is that the preparation method of the polymer emulsion includes the following steps: heating 40 parts by weight of PEG1000 to 110°C, vacuuming for 2 hours, and reducing the temperature Add 20 parts by weight of 1,6-hexamethylene diisocyanate, 1 part by weight of 1,4-butanediol, 0.5 part by weight of dibutyltin dilaurate to 50°C, and react at 70°C for 4 hours to obtain a polymer emulsion .

Abstract

The invention belongs to the technical field of antibiosis, and particularly relates to an antibacterial and antiviral mask. The antibacterial and antiviral mask comprises a mask body; the mask body sequentially comprises a fiber inner layer, an antibacterial layer and a protective layer from inside to outside, and the fiber inner layer and the antibacterial layer as well as the antibacterial layer and the protective layer are made into the mask body through full-automatic planar mask flaking. According to the antibacterial and antiviral mask, the innermost layer is made of the bamboo fibers and the cotton fibers, the skin affinity is good; the protective layer is made of the medical non-woven fabric, the water absorption performance is poor, and the air permeability is good; meanwhile, the polylactic acid electrostatic spinning nanofiber membrane dipping finishing liquid is adopted as the antibacterial layer, the air permeability is good, and a good filtering effect can be achieved; by using the mask, the sterilization efficiency is high, the repeated utilization rate is high, and the medical cost is reduced.

Description

Technical field [0001] The present invention belongs to the field of antibacterial technology. More specifically, the present invention relates to an antibacterial and antiviral mask. Background technique [0002] At present, my country's medical masks are mainly divided into three types: medical protective masks with the highest protection level, medical surgical masks commonly used in invasive operating environments such as operating rooms, and ordinary-level disposable medical masks; from the perspective of mask materials, polypropylene is high The special material for melt finger non-woven fabric becomes the best choice. It produces polypropylene products with a melt mass flow rate of 33-41g / min, which meets the standard of polypropylene non-woven fabric. The main material of meltblown non-woven fabric is polypropylene, which is a kind of ultrafine electrostatic fiber cloth, which can capture dust. When droplets containing pneumonia virus come close to the meltblown non-woven...
