Technical Field

The invention relates to the technical field of mask materials, in particular to a preparation method of a traditional Chinese medicine antibacterial mask material.

Background

The bacteria are very small and exist everywhere, however, some bacteria are pathogens of diseases, can spread the diseases among normal human bodies through various ways, such as contact, alimentary canal, respiratory tract, insect bite and the like, have strong infectivity and great harm to the society. Therefore, people develop and manufacture various bacteriostatic products for daily hand washing, clothes disinfection, wound disinfection and the like.

In hospitals, clinics, biological laboratories and other places, the mask needs to be worn for isolating bacteria, but the existing masks mostly prevent the bacteria from passing through the mask as much as possible through the aperture of the material. However, although this method can prevent bacteria from entering to some extent, the mask has a very short service life.

Therefore, the development of the material for the traditional Chinese medicine bacteriostatic mask with good bacteriostatic effect has important practical significance.

2) putting polylactic acid, an emulsifier OP-10 solution and the traditional Chinese medicine bacteriostatic concentrated solution prepared in the step 1) into a reactor; controlling the mass ratio of polylactic acid to the traditional Chinese medicine bacteriostatic concentrated solution to be 1: 1-3; the ratio of the oil phase to the external water phase is 13-20: 100, and the mixture is stirred and reacts for 10-20 hours at the temperature of 30-60 ℃ to prepare a traditional Chinese medicine bacteriostatic microcapsule solution;

3) uniformly spraying the traditional Chinese medicine bacteriostatic microcapsule solution to the mask non-woven fabric material, and 3) uniformly spraying the traditional Chinese medicine bacteriostatic microcapsule solution to the mask material to obtain the traditional Chinese medicine bacteriostatic mask material.

Preferably, in the step 1), the mass ratio of the radix sophorae flavescentis to the cortex moutan to the dandelion is 3-10: 4-8: 18-25.

According to the preferable scheme, the mass of the peppermint oil accounts for 0.01-0.1% of the mass of the traditional Chinese medicine bacteriostatic concentrated solution.

Furthermore, the mass of the peppermint oil accounts for 0.03-0.08% of the mass of the traditional Chinese medicine bacteriostatic concentrated solution.

As a preferred scheme, the mass ratio of the polylactic acid to the Chinese medicinal bacteriostatic concentrated solution is controlled to be 1: 2.

Preferably, in the step 3), the mask material is a mask non-woven fabric material.

Preferably, in the step 3), the mask material is a wood pulp fiber filter element.

The invention has the beneficial effects that:

1. the ethanol extract of the sophora flavescens, the moutan bark and the dandelion is mixed with the peppermint oil, so that the bacteriostatic effect is very good.

2. The traditional Chinese medicine microcapsule solution with remarkable bacteriostatic effect is sprayed to the mask non-woven fabric material or the wood pulp fiber filter core, so that the mask non-woven fabric material and the wood pulp fiber filter core have remarkable bacteriostatic effect, and meanwhile, the traditional Chinese medicine extracting solution is prepared into traditional Chinese medicine microcapsules which have a slow release effect, so that the bacteriostatic effect of the mask non-woven fabric material and/or the wood pulp fiber filter core can be maintained for a long time.
