Problems solved by technology

[0003] When melt-blown cloth is used as a mask filter material, in order to ensure its sterilization and filtration effect, electrostatic electret is usually required; however, the electrostatic adsorption sterilization effect is not long-lasting, and when the melt-blown cloth is wetted by water, it will cause electrostatic discharge. lead to sterilization failure

Embodiment 1

[0043] Silver zinc phosphate glass material, measured in parts by mass, includes the following raw materials:

[0044] 20 parts of ZnO, Ag 2 O 1 serving, P 2 O 5 35 servings, Na 2 O 14 servings.

[0045] The preparation method of silver zinc phosphate glass material is as follows:

[0046] 1) ZnO, Ag 2 O.P 2 O 5 with Na 2 Mixed with O, melted at 1000°C;

[0047] 2) Cooling, pulverizing and sieving after melting to obtain a silver zinc phosphate glass material with a particle size of not more than 10 μm, the silver zinc phosphate glass material has a stable structure and can withstand high temperatures above 550°C.

[0048] To detect the acute toxicity of silver zinc phosphate glass materials to experimental animals:

[0049] Select 4 healthy rats, 180-220 g, half male and half male, fasted overnight before the test.

[0050] The silver-zinc phosphate glass material was made into a suspension with water, and 1 mL / 100 g was administered by gavage. After 14 days, the p...

Embodiment 2

[0056] An antibacterial masterbatch, the raw materials of each 30g are as follows:

[0057] 21g of polypropylene, 0.6g of silver zinc phosphate glass material of Example 1, 6g of graphene, 1.2g of butyl titanate, pentaerythritol tetrakis[beta-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate ester] 0.6g, polyvinylpyrrolidone 0.6g.

[0058] The preparation method of the antibacterial masterbatch is as follows: the polypropylene is melted at 250° C., and the silver zinc phosphate glass material, graphene, butyl titanate, tetrakis[beta-(3,5-di-tert-butyl-4-hydroxybenzene are added. base) pentaerythritol propionate] and polyvinyl pyrrolidone, mixed uniformly, cooled and cut to obtain antibacterial masterbatch.

Embodiment 3

[0060] An antibacterial meltblown cloth, the raw materials per 120g are as follows:

[0061] 80g of polypropylene, 10g of maleic anhydride grafted polypropylene, 30g of antibacterial masterbatch of Example 2;

[0062]The preparation method of antibacterial meltblown cloth is as follows:

[0063] Polypropylene, maleic anhydride grafted polypropylene and antibacterial masterbatch are mixed, melted at 250 ℃, spin-sprayed and spread to make 20g / m 2 Antibacterial meltblown cloth can be used as sterilization filter material.

Abstract

The invention discloses an antibacterial melt-blown cloth, a preparation method and application thereof, and belongs to the technical field of melt-blown cloth production. The antibacterial melt-blown cloth includes a polypropylene layer; the polypropylene layer is measured in parts by mass and includes the following raw materials: 70-90 parts of polypropylene, 5-15 parts of maleic anhydride grafted polypropylene, 15-35 parts of antibacterial masterbatch; The masterbatch is obtained by mixing and cooling polypropylene, silver-zinc phosphate glass, graphene, and additives; among them, the amount of silver-zinc phosphate glass accounts for 0.5‑1% of the total mass of the polypropylene layer, and the amount of graphene accounts for 2-8% of the total mass of the polypropylene layer, and the auxiliary agent accounts for 0.1-5% of the total mass of the polypropylene layer. The antibacterial property of the melt-blown cloth of the present invention is effectively enhanced, and long-lasting antibacterial effect is realized.

Description

technical field [0001] The invention relates to the technical field of melt-blown cloth production, in particular to an antibacterial melt-blown cloth and a preparation method and application thereof. Background technique [0002] Meltblown cloth is made of polypropylene as the main raw material, and high-speed hot air flow is used to draw the thin stream of melt extruded from the spinneret hole of the die to form ultra-fine fibers and collect them on the condensing screen or roller. Bonded to become a non-woven fabric. It has many voids, fluffy structure, good filterability, shielding, heat insulation and oil absorption; it can be used as filter material, isolation material, absorption material and other fields. [0003] When melt-blown cloth is used as a mask filter material, in order to ensure its sterilization and filtration effect, electrostatic electret is usually required; however, the sterilization effect of electrostatic adsorption is not long-lasting. lead to ste...
