Abstract

The invention discloses a temperature-sensitive slow-release protective mask sticker and a preparation method thereof, and relates to the technical field of traditional Chinese medicine functions. The protective mask stickers include a non-woven backing layer, a drug-containing gel layer, and an anti-adhesive layer in sequence. The raw materials of the drug-containing gel layer include shikonin temperature-sensitive nanoparticles, partially neutralized sodium polyacrylate, glycerin, poly Vinylpyrrolidone, glycol, tartaric acid, silanediol salicylate and drinking water. It also provides the preparation method of protective mask stickers: preparation of shikonin temperature-sensitive nanoparticles, configuration of drug-containing gel layer, coating and sticking of anti-adhesive layer to make finished products. The medicinal materials selected in the present invention have a wide range of sources, mild medicinal properties, safe and reliable administration, high bioavailability of shikonin temperature-sensitive nanoparticles, strong stability of nanomaterials, good air permeability of the product itself, and slow release of medicines, which increases the cost of mask stickers. The comfort level can eliminate the bacteria and viruses adsorbed on the mask outside the body, so as to achieve the purpose of prevention.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine functions, in particular to a temperature-sensitive slow-release protective mask sticker and a preparation method thereof. Background technique [0002] Suspended particles in the air can stay in the atmosphere for a long time, and can enter the human body with breathing, accumulate in the trachea or lungs, and affect health. Due to the warming of the atmosphere caused by the deterioration of the atmosphere, smog is becoming more and more serious nowadays. The substances harmful to health are mainly aerosol particles with a diameter of less than 10 microns, and the diameter of virus particles floating in the air is generally less than 0.3 microns. It can directly enter and adhere to the human respiratory tract and alveoli, especially submicron particles will deposit in the upper and lower respiratory tract and alveoli respectively, causing acute respiratory diseases.
