The present invention belongs to the technical field of nanomaterial preparation, and discloses a method for preparing a self-repairing highly hydrophobic and highly transparent organic glass film layer. The method comprises: the first step of treating the organic glass surface with polysiloxane and solidifying it into a film; the second step of grinding and dispersing the nano-diamond prepared by the detonation method, oxidizing and removing impurities, extracting nano-diamond particles of a certain particle size by high-speed centrifugation, and dispersing them together with Ag@TiO2 nano-particles prepared by the hydrothermal method in an ethanol solution of water and polyvinyl pyrrolidone to form a PVP dispersion of the two, and then spraying them on the organic glass surface, drying and solidifying them into a film. The film layer prepared by the present invention has good hydrophobicity and high light transmittance, and can self-repair under light. The production method has simple steps, low energy consumption, is suitable for industrial production, and has strong practicality.

The application discloses a composite solid decoloring powder and a preparation method thereof, and belongs to the technical field of water treatment agent preparation. The modified nano titanium dioxide is obtained by coating titanium dioxide with 3-methyl acrylic acid sulfopropyl potassium salt grafted polydopamine. The titanium dioxide has photocatalytic effect and antibacterial property, can catalytically decompose pollutants in sewage, inhibit the breeding of bacteria in water, and can catalytically decompose free formaldehyde in dicyandiamide formaldehyde polycondensate. The modified nano titanium dioxide is loaded on phenolic resin foam, and after calcination, the nano titanium dioxide / foam carbon powder is formed. The large specific surface area and porous property of the foam carbon can increase the capture and fixation of free formaldehyde, and can synergistically accelerate the catalytic degradation of formaldehyde with the titanium dioxide. The dicyandiamide formaldehyde polycondensate grafted with castor oil is in-situ polymerized on the surface of the matrix. The castor oil grafting can significantly improve the dicyandiamide formaldehyde polycondensate, significantly increase the molecular weight, and increase the capture capacity.

And plane three-way fabric can provide isotropic tensile effect.

The invention discloses an anti-inflammatory composition containing limonin, a pneumonia spray and a preparation method. The anti-inflammatory composition containing limonin comprises the following components in parts by weight: 60-70 parts of limonin coated by cyclodextrin and 30-40 parts of clindamycin phosphate. The cyclodextrin is of an annular structure, and a cavity is formed in the cyclodextrin; the outer edge is hydrophilic and the inner cavity is hydrophobic, so that limonin can be wrapped; after the anti-inflammatory composition enters the lung through the respiratory tract, limonin in the anti-inflammatory composition can be gradually released along with dissolution of cyclodextrin; the clindamycin phosphate and the cyclodextrin are both dissolved in water, the clindamycin phosphate shows antibacterial activity after entering a human body, limonin is gradually released along with dissolution of the cyclodextrin, the synergistic effect of the clindamycin phosphate and the limonin can be stable and continuous, then the anti-inflammatory effect is continuous, and it is ensured that the pneumonia treatment effect is continuously and stably carried out.

This utility model discloses an anti-mildew composite artificial leather, comprising a surface layer, an antibacterial layer, an artificial leather layer, and an inner layer. The antibacterial layer is laminated between the surface layer and the artificial leather layer, and the inner layer is laminated on the lower surface of the artificial leather layer. The surface layer has several ventilation holes located at its edges. The antibacterial layer reduces bacterial growth on the artificial leather layer. The polyurethane coating on the surface layer reduces most of the moisture contact with the antibacterial layer. The ventilation holes allow moisture entering the antibacterial layer from the fabric edges to evaporate more quickly. The inner layer is woven from antibacterial fibers and cotton fibers, providing both antibacterial properties and good comfort.
