5results about How to "Long-term antibacterial effect" patented technology

The present invention belongs to the technical field of laundry detergent, and specifically relates to an aerosol-type underwear laundry detergent and a preparation method thereof. The aerosol-type underwear laundry detergent provided by the present invention is prepared from polyethylene glycol-400, natural glycerin, a detergent, a bactericide, a preservative, anhydrous calcium chloride, polyethylene glycol 6000 distearate, a composite enzyme, rose essential oil, cottonseed oil, a propellant and water. The aerosol-type underwear laundry detergent provided by the present invention can remove blood stains, yellow stains, etc., and has a long-term antibacterial effect, is easy to use, has good sealing, and will not cause the laundry detergent to exceed the standard of microorganisms due to the humid environment in which it is placed, or inactivate the effective ingredients to reduce the decontamination ability.

This invention discloses an antibacterial air filter material and its preparation method, relating to the field of filter material technology. In preparing the antibacterial air filter material, terephthalaldehyde is reacted sequentially with 2-aminobenzimidazole and diethyl phosphite to obtain a phosphorus-nitrogen composite flame retardant; silica is reacted sequentially with γ-glycidyl etheroxypropyltrimethoxysilane and 1-hydroxymethyl-5,5-dimethylhydantoin to obtain modified silica; the modified silica is chlorinated with sodium hypochlorite to obtain haloaminated silica; 70-80 parts of polyacrylonitrile, 5-6 parts of the phosphorus-nitrogen composite flame retardant, and 3-4 parts of haloaminated silica are formulated into a spinning solution, and electrospinned to obtain a polyacrylonitrile fiber membrane; the polyacrylonitrile fiber membrane is reacted sequentially with ethylenediamine and curcumin to obtain the antibacterial air filter material. The antibacterial air filter material prepared by this invention has the advantages of both antibacterial and flame retardant properties.

The invention belongs to the field of food packaging, and relates to a preparation method and application of a slow-release antibacterial fiber membrane based on a Janus structure, and the preparation method comprises the following steps: taking a chitosan / polylactic acid nanofiber membrane as a receiving substrate, and adopting a double-needle parallel electrostatic spinning or needleless electrostatic spinning method to prepare the slow-release antibacterial fiber membrane based on the Janus structure. Performing opposite spinning on the positively charged spinning solution A and the negatively charged spinning solution B to obtain an electrostatic spinning fiber membrane, or taking a petal-shaped nano ZnO fiber membrane as a receiving substrate, and adopting a double-needle parallel electrostatic spinning method or a needle-free electrostatic spinning method to obtain the electrostatic spinning fiber membrane. Performing opposite spinning on the positively charged spinning solution C and the positively charged spinning solution D to obtain an electrostatic spinning fiber membrane, and performing post-treatment on the electrostatic spinning fiber membrane to obtain the slow-release antibacterial fiber membrane. The food fresh-keeping agent is applied to food fresh-keeping. The preparation method disclosed by the invention is simple in process, and the prepared slow-release antibacterial fiber membrane is high in interlayer bonding firmness and excellent in antibacterial performance, and has a relatively good application prospect in food preservation.

The present application relates to the field of daily chemical products, and discloses a light-color transparent odorless concentrated sterilization bead content, which comprises the following components in percentage by mass: p-chloro-m-xylenol 15-25%, non-ionic surfactant 0-5%, anionic surfactant containing at least C21 dibasic acid 10-20%, alcohol solvent containing at least isohexyl alcohol 43-55%, inorganic alkali agent 3-5%, bacteriostatic agent 0-2%, essence 0-2%, and water in remainder amount. The concentrated sterilization bead content of the present application uses inorganic alkali to replace organic amine alkali agent, so that the product appearance is stable and transparent light color under low cost conditions; the present application uses the combination of "non-ionic surfactant+C21 dibasic acid+isohexyl alcohol" to replace alcohol and ether solvents, so that the p-chloro-m-xylenol is significantly solubilized under the premise of no odor and safety.

The invention provides antibacterial gauze as well as a preparation method and application thereof, and belongs to the technical field of gauze. The antibacterial gauze comprises two layers of gauze and fibers distributed between the two layers of gauze; the fiber comprises a fiber tube and a filler filled in the fiber tube; the fiber tube comprises a first degradable polymer; the filler comprises a second degradable polymer and an antibacterial agent. The antibacterial gauze provided by the invention comprises the fibers, the fibers comprise the fiber tubes and the filler filled in the fiber tubes, the filler contains the antibacterial medicine, and when the antibacterial gauze is used for binding up a wound, polymers in the fiber tubes and the filler are gradually degraded, so that the antibacterial medicine in the filler is gradually released, and the antibacterial effect is improved. Therefore, the antibacterial time of the gauze is prolonged. The result of the embodiment shows that the release time of the antibacterial medicine in the filler in the antibacterial gauze provided by the invention reaches 28 days, and the antibacterial gauze has a long-term antibacterial effect.
