The invention discloses an antibacterial outer shell used for an automotive electronic igniter. The outer shell comprises the following raw materials in parts by weight: 125-135 parts of a main material, 1-2 parts of isopropyl tri(dioctylpyrophosphate) titanate, 0.5-1.2 parts of maleic anhydride, 1-5 parts of a composite antibacterial agent, 5-10 parts of precipitated barium sulfate, 2-6 parts ofheavy calcium carbonate, 1-6 parts of calcined kaolin, 2-4 parts of graphene, 1-2 parts of trimethylethoxysilane, 2-4 parts of a dispersant, 1-2 parts of an anti-aging agent, and 1-2 parts of a defoaming agent, wherein the composite antibacterial agent is prepared by the following processes: performing uniform mixing on houttuynin and toluene, adding a hydrogen peroxide aqueous solution dropwise,raising the temperature, performing stirring, performing extraction by adopting dichloromethane, collecting an organic phase, performing evaporation to dryness, adding nano zinc oxide, nano silver oxide, sepiolite powder and water, performing mixing, raising the temperature, performing stirring, raising the temperature, continuing stirring, performing cooling, performing filtering, performing washing, and performing drying to obtain the composite antibacterial agent.

The invention belongs to the field of medicinal preparations and particularly relates to a preparation method of a lipid microsphere preparation of houttuynin and a houttuynin derivative. The lipid microsphere preparation contains the houttuynin or the houttuynin derivative. The preparation takes phospholipid and other surfactants as emulsifiers and takes high-purity plant oil as a solvent. Lipid microspheres are prepared by high-pressure homogenizing equipment. Compared with the conventional houttuynin injection, the lipid microsphere preparation avoids the application of latent solvents such as Tween and the like and remarkably improves the stability of a preparation.

A composite medicine in the form of injection for treating atypical pneumonitis, etc is prepared from medicine Libaweilin 50-2500 mg, sodium neohouttuyfonate 0.25-25 mg and medicinal auxiliary through heating, stirring, filter, and regulating pH value.

The invention discloses an antibacterial glass fiber air filter paper, which is prepared from the following raw materials in parts by weight: 80 to 100 parts of alkali-free glass microfiber, 10 to 15parts of polytetrafluoroethylene, 15 to 20 parts of dimethyl sulfoxide, 3 to 5 parts of houttuynin, 2 to 3 parts of 4-isopropyl-2-hydroxy-cycloheptyl-2,4,6-triene-1-ketone, 2 to 3 parts of methyl n-nonyl acetaldehyde, 0.3 to 0.5 part of an antibacterial agent, and 3 to 5 parts of a binder. The invention also discloses a preparation method of the antibacterial glass fiber air filter paper. The filter paper prepared by the invention can effectively block various bacteria in the air under the coaction of various raw materials to achieve the antibacterial effect; the bacterium resistance and sterilization are carried out separately inside and outside the filter paper by different substances, thereby effectively improving the air filtering effect.

The invention discloses a preparation method of antibacterial and antistatic coating and belongs to the technical field of coating preparation. The preparation method disclosed by the invention has the beneficial effects that montmorillonite and marble contain a large amount of metal oxides such as MgO, CaO and ZnO and the like, the metal oxides are inorganic antibacterial agent and are also goodconducting materials; both tea polyphenol and houttuynin have antibacterial and antiseptic effects, and by the fermenting action, the tea polyphenol and the houttuynin can be combined with inorganic minerals; compared with polyanilines with other structures, the polyaniline with a nanofiber structure has higher conductivity; carbon nanotubes have good mechanical property and electric property simultaneously, and by combination of polyaniline nanofiber with the copper-loaded surface and the carbon nanotubes with the copper-loaded surfaces, the conducting property of the coating is improved, simultaneously the coating has good antibacterial property and wear resistance; by adoption of a special spraying mode for loading copper, the copper can be almost loaded on the surfaces of the polyaniline nanofiber and the carbon nanotubes, so that the antibacterial property and the conducting property are improved and the preparation cost is greatly reduced.
