The invention provides an adhesive preparation including a backing, and a pressure-sensitive adhesive layer which contains a drug and is disposed on at least one side of the backing; in which the backing includes a polyester film having a thickness of 0.5 to 6.0 [mu]m, and a polyester nonwoven fabric directly bound to the film. The pressure-sensitive adhesive layer preferably is directly or indirectly laminated on the nonwoven-fabric side of the backing. The adhesive preparation of the invention is flexible enough to comply to the skin and has reduced skin irritation and high stability.

The invention discloses a monascorubrin mordant dyeing method of silk textile, which is characterized by comprising the following step: using monascorubrin to perform mordant dyeing of silk textile by taking rare earth as mordant, wherein the use of the mordant is 0.5-2 g / L, and the concentration of the monascorubrin dye is 1-5% owf. The method uses the food coloring agent monascorubrin in the dyeing process of real silk, expands the application field of the monascus industry, can obtain relatively good color yield and color fastness of monascorubrin on the silk textile through the use of themonascorubrin, and realizes the green ecological staining process of silk textile.

The invention relates to a method for preparing dendritic nano-silver by liquid-phase synthesis. The method is characterized by comprising the following steps: a silver-ammonia solution with silver-ammonia concentration of 0.1 mol / L to 0.5mol / L is prepared, then a crystal-formation guider and a nometer protective agent are added, stirring is carried out till the mixed solution is evenly mixed, and reaction solution is obtained; an ascorbic acid solution with concentration of 0.4mol / L to 0.8mol / L is dripped into the reaction solution to carry out reduction reaction, the solution after reactionis directly filtered by decompression, the solid phase after filtering is baked in an oven to remove water, so as to obtain the dendritic nano-silver. The method has simple preparation process, the reagent used is nontoxic and of environmental protection, the diameter of the dendritic nano-silver obtained is less than 30nm, the length of the dentrites is less than 100nm, the cluster length of thedentrites is less than 200nm, and the granularity of the dendritic nano-silver is even and the structure is stable. The dendritic nano-silver obtained by the method which is composite with polymers can improve conductivity, conductive circuit can be formed only with relatively little silver powder, filling quantity of silver powder can be reduced and cost of conductive agents can be saved.

The invention relates to the field of papermaking and paper chemicals, aims to solve the problem that a paper used polyacrylamide dry strength additive, which has an efficient enhancement effect, and is good in adhesiveness, and environmentally friendly, is required to be prepared in the papermaking industry at present, and provides a preparation method of cross-linked polyacrylamide with high molecular weight and narrow distribution and application of the cross-linked polyacrylamide to papermaking. The cross-linked polyacrylamide prepared with the preparation method has higher weight-average molecular weight and narrower molecular distribution, and has the advantages of good enhancement effect, low loss of white water, good adhesiveness, less jello, environmental protection and the like. When the cross-linked polyacrylamide is applied to various fields, actual effective constituents are concentrated better, the operating barrier is reduced, and fewer side effects are caused.
