The invention relates to a method for preparing an uramine-type macromolecule anti-bacterial agent, comprising two steps as follows: A, mixing any one solution of guanidine hcl, Polyhexamethyleneguanidine chloride and polyhexamethylene biguanide hydrochloride with maleic anhydride solution; introducing nitrogen for constant-temperature water bath reaction to obtain functional uramine salt; B, mixing functional uramine salt solution with acrylamide and / or styrene for constant-temperature water bath reaction to obtain ivory-white stringy liquid; depositing soft white solid with solvent for vacuum drying to obtain ivory-white bulk uramine-type copolymer, i.e, uramine-type macromolecule anti-bacterial agent. The uramine-type macromolecule anti-bacterial agent has remarkable effect and simple synthesis process, ensures that the anti-bacterial group is hard to move and the processing thermal stability is excellent through copolymerization on macromolecule long chain. The invention can be widely used in fields of plastic, dope, powder dope, rubber, wood plastic, rubber plastic, spinning, water processing, and the like.

The invention relates to a composition for killing microbes, which is mainly used for hand antisepsis, surgical hand antisepsis and antisepsis of skins and mucosa and can be also used for killing the microbes at the surfaces of the articles; polyhexamthylene guanidine hydrochloride and ethanol are adopted as main active fungicide ingredients to be combined with a fungicide synergistic agent isopropanol, wherein the concentration of the ethanol is 79-467 g / L, the concentration of the polyhexamthylene guanidine hydrochloride is 0.01-15 g / L and the concentration of the isopropanol is 3-54 g / L; meanwhile, a moisturizer, a stabilizing agent, a thickening agent and other agents can be added as needed to obtain different dosage forms; and the composition has the advantages of good fungicide effect, high speed, no washing, high stability, reduction of skin irritation of the product and functions of protecting and moisturizing skins.

The invention discloses a method for producing adipic acid, hexamethylenediamine hydrochloride and polyhexamethylene (di)guanidine chloride from waste nylon-66 serving as a raw amerial through depolymerization, which is characterized by comprising the following steps of: depolymerizing the waste nylon-66 by using hydrochloric acid to obtain refined adipic acid and hexamethylenediamine hydrochloride; polymerizing the hexamethylenediamine hydrochloride and dicyandiamide (in a molar ratio of 1:1) at the temperature of between 170 and 190DEG C for 1 to 3 hours to obtain a white or pale yellow solid polyhexamethylene diguanidine chloride; and adding dicyandiamide and ammonium chloride powder in a molar ratio of 1:2 into a reactor, performing reaction at high temperature for 1 to 3 hours, slowly adding hexamethylenediamine hydrochloride powder, continuously reacting for 3 to 7 hours to obtain a white or pale yellow solid polyhexamethylene guanidine chloride. The method improves production efficiency, reduces production cost, and solves the problems of difficult separation of the product hexamethylenediamine due to depolymerization, low yield and poor benefit; and the technological process is environment-friendly, simple and convenient, and is suitable for industrial production.

The present invention relates to a manufacture method of micro-organism-inhibiting gel. The manufacture method comprises the following steps: 1) raw materials are weighed and the weighed raw materialsare cleaned and selected for a standby application; 2) 20 ml of ethanol is taken to dissolve 3 g of methyl 4-hydroxybenzoate to prepare a methyl 4-hydroxybenzoate solution for a standby application;3) radix sophorae flavescentis, cortex phellodendri, fructus cnidii, safflowers and mint are taken, water is added, and the materials are cooked twice to obtain an extractum for a standby application;4) 20 g of carbomer is taken, 100 g of purified water is added, and the carbomer is soaked for 24 hours until fully swollen to obtain a gel matrix for a standby application; 5) the methyl 4-hydroxybenzoate solution is mixed with the extractum, polyhexamethylene biguanide hydrochloride and glycerin are added, triethanolamine is added dropwise to adjust pH to 7, purified water is supplemented to atotal mass of 1,000 g, and stirring and mixing evenly are conducted for a standby application; and 6) sub-packaging, inspecting, packaging, and storing after qualified are conducted. Advantages are asfollows: the micro-organism-inhibiting gel with an average micro-organism-inhibiting rate of 50% or more against staphylococcus aureus, candida albicans and escherichia coli can be prepared, and themicro-organism-inhibiting gel has remarkable results in diseases of genital itching, waist and abdomen pains, abnormal leukorrhea, frequent urination, odynuria, etc.

The invention provides a disinfecting washing agent. The disinfecting washing agent is prepared from, by weight, 10-15 parts of an anionic surfactant or a nonionic surfactant, 1-3 parts of sodium alginate, 3-5 parts of lignosulfonate, 5-8 parts of polyhexamethylene biguanidine hydrochloride, 5-10 parts of divaricate saposhnikovia extract, 1-3 parts of an active enzyme and 40-50 parts of deionized water. The disinfecting washing agent has the dual functions of stain removal and disinfection, and is mild, free of simulation or toxin and friendly to the environment.
