The invention discloses a slightly foaming flame-retardant polyurethane material, and a preparation method thereof. The slightly foaming flame-retardant polyurethane material is prepared from isocyanate, a polycarbonate dihydric alcohol, a filling material, a pigment, a halogen free fire retardant, a flame retardant synergistic agent, a chemical foaming agent, a physical foaming agent, an anti-oxidant, an ultraviolet ray absorber, and a mildew-resistant antiseptic. The preparation method comprises following steps: 1, the polycarbonate dihydric alcohol and the filling material are subjected topre-mixing; 2, isocyanate is added, full reaction is carried out, the pigment, the halogen free fire retardant, the flame retardant synergistic agent, the chemical foaming agent, the physical foamingagent, the anti-oxidant, the ultraviolet ray absorber, and the mildew-resistant antiseptic are added for full reaction. The internal part of the slightly foaming flame-retardant polyurethane materialpossesses uniform micropores; the elasticity is high; the flame resistance, the aging resistance, the mechanical properties, the wear resistance, and the slide resistance are excellent; no smell is observed; the preparation method is safe, is friendly to the environment, is simple, and is convenient for large-scale industrialized production.

A device used for applying an antiseptic preparation to a surgical site of a patient prior to surgery outside of an operating theater. A loose-fitting bag is provided which encloses the surgical site by securing the open end(s) to the patient by closing means. A high friction scrub surface is provided in the bag. A method and apparatus are also provided for releasing antiseptic into the interior of the bag. The method provides that the surgical site can be scrubbed within the bag so as to properly prepare the skin for surgery. A temperature indicator for the antiseptic preparation is also provided.

This disclosure provides generally for antimicrobial compositions and methods of use comprising an anthocyanin, an anthocyanidin or metabolites thereof. Methods for promoting healing of a wound using these compositions are also disclosed. These compositions have broad spectrum antimicrobial activity and are safe for human and animal uses. Further, these compositions are safe for medical uses and industrial uses as antiseptic preparations to reduce or prevent microbial growth.

The present invention relates to biguanide-containing liposomes and antiseptic preparations based on biguanide-containing liposomes, where the liposomes are characterized in that they are essentially free from lipids with anionic head groups, to the preparation of the biguanide-containing liposomes and of the antiseptic preparations, and to their possible uses and to the products arising from their use, in particular wound coverings.

The invention discloses a multilayer laundry detergent tablet, and a preparation method thereof. Each of the multilayer laundry detergent tablet comprises two layers or more than two layers of laundry detergent single tablets; an adhesive substance is arranged between the two layers of laundry detergent single tablets, or among the more than two layers of laundry detergent single tablets; and the adhesive substance is one or a mixture of a plurality of ingredients selected from a liquid bio-enzyme, a liquid perfume, a liquid softening agent, a liquid color protecting agent, and a liquid antiseptic. The preparation method comprises following steps: the surface of each laundry detergent single tablet is coated with the adhesive substance via smearing or spraying, and then two layers or more than two layers of the laundry detergent single tablets are glued together via extraction. The multilayer laundry detergent tablet is high in stability and washing capacity; deposition of insoluble substances on clothing is not caused; and the preparation method is simple.

The invention relates to the preparation technology of a sol, and aims at providing a preparation method of a self-cleaning anticorrosion sol for a metal substrate. The method comprises the following steps: feeding tetramethyl orthosilicate or tetraethoxysilane into a saturated alcohol solvent of ammonia gas under an agitating condition; then feeding water to react; performing rotary evaporation to remove some alcohol solvent to obtain high-solid-content particular colloidal silica sol; further feeding Al(OH)3 sol; ageing; further feeding nanometer titanium dioxide powder and glass beads; agitating; filtering the sol; further feeding a catalyst for regulating the pH; dropwise adding organo-siloxane to react to obtain the self-cleaning anticorrosion sol. According to the method, anatase titanium dioxide powder is introduced on the basis of Al(OH3) sol in-situ coated and modified coated silica sol and is grinded and uniformly dispersed into the Al(OH3) sol in-situ coated and modified coated silica sol, and therefore, the anatase titanium dioxide powder can be uniformly dispersed in the prepared coating to effectively improve the self-cleaning performance of the coating on the substrate while the corrosion resistance is ensured.
