Embodiment 1

[0029] An antibacterial composite layer includes an antibacterial outer layer and an antibacterial inner layer. The antibacterial outer layer is a starch-based polylactic acid composite material, the antibacterial outer layer is loaded with an inorganic nano-antibacterial agent, and the starch is corn starch. The antibacterial inner layer is ramie-polypropylene-montmorillonite composite material, lipase is adsorbed on the antibacterial inner layer, and chitosan is coated on the surface of the antibacterial inner layer.

[0030] The preparation method of the antibacterial outer layer is to add cornstarch, plasticizer, inorganic nano antibacterial agent and polylactic acid resin into the internal mixer at a mass ratio of 0.05:0.03:0.2:1 and mix them, and melt them in a twin-screw extruder Granulating to obtain granules, and then putting the granules into a spinning machine for spinning treatment. It can be processed by conventional spinning process. The plasticizer is glycerin...

Embodiment 2

[0033] The difference between this example and Example 1 is that the mass ratio of cornstarch, plasticizer, inorganic nano-antibacterial agent and polylactic acid resin in the antibacterial outer layer is 0.05:0.03:0.3:1.

Embodiment 3

[0035] The difference between this example and Example 1 is that the mass ratio of cornstarch, plasticizer, inorganic nano-antibacterial agent and polylactic acid resin in the antibacterial outer layer is 0.05:0.06:0.1:1.

Abstract

The invention relates to the technical field of antibacterial masks, and discloses an antibacterial combined layer which comprises an antibacterial outer layer and an antibacterial inner layer. The antibacterial outer layer is made of a starch-based polylactic acid composite material and is loaded with an inorganic nano antibacterial agent, and lipase is adsorbed on the antibacterial inner layer.The invention further discloses an antibacterial protective mask comprising the antibacterial layer, the antibacterial protective mask comprises a dustproof outer layer, a filter layer, an antibacterial combination layer and a skin-friendly layer which are connected in sequence, the antibacterial outer layer in the antibacterial combination layer is attached to the filter layer, and the antibacterial inner layer in the antibacterial combination layer is attached to the skin-friendly layer. The antibacterial material can be prevented from being polluted by bacterial carcasses or bacterial secretions, the antibacterial effect is continuously achieved, and the antibacterial material is green, degradable and good in antibacterial effect.

Description

technical field [0001] The invention belongs to the technical field of protective masks, and in particular relates to an antibacterial composite layer and an antibacterial protective mask comprising it. Background technique [0002] The pollution of air and water, the proliferation of viruses or other bacteria pose a huge threat to people's health. Masks are a convenient protective measure used to protect humans from germs. [0003] Traditional antibacterial masks include gauze masks and masks made of non-woven materials. Due to the complex fiber accumulation structure of non-woven fibers and the three-dimensional random distribution of fibers, the material contains a large number of tiny voids, and the particles undergo various types of bending around the fibers. Channels or paths can greatly reduce the resistance when airflow passes through, and at the same time, due to its fast production speed and excellent structural performance, it is widely used in the mask filter ma...
