The invention discloses an anti-wrinkle anti-ultraviolet core bast fiber spinning yarn and a preparation method thereof, and relates to the technical field of spinning yarns. When the anti-wrinkle and anti-ultraviolet core bast fiber spinning yarn is prepared, 6-bromine-1-hexyl acrylate and N-methylimidazole react to prepare an alkenyl imidazolium salt monomer; the preparation method comprises the following steps: carrying out a reaction on methyl p-hydroxycinnamate and acryloyl chloride to prepare an alkenyl cinnamate monomer; grafting an alkenyl imidazolium salt monomer and an alkenyl cinnamate monomer onto the pretreated flax fiber to prepare a modified flax fiber; performing blowing, cotton carding, drawing and roving processes on the modified flax fibers to obtain flax roving; converging and twisting the rough flax yarn and the polyester filament yarn to obtain core flax yarn; and finishing the core hemp yarn with 1, 6-hexamethylenediamine and coumarin-7-carboxylic acid in sequence to obtain the anti-wrinkle and anti-ultraviolet core hemp spun yarn. The anti-wrinkle and anti-ultraviolet core bast fiber spinning yarn prepared by the invention has the advantages of ultraviolet prevention and bacteria resistance.

The present disclosure relates to a protective layer having a self-repairing characteristic and a shape memory characteristic on one surface of a display panel. To this end, the protective layer may be manufactured from a product consisting of methyl methacrylate (MMA), hexyl methacrylate (HMA) and cinnamyl (Ci) mixed in a predetermined ratio that can ensure predetermined optical transparency, predetermined rigidity, or predetermined restorability against plastic deformation. Other various embodiments are possible.

This invention relates to the field of dampening solution technology and discloses a rinse-free, alcohol-free dampening solution and its preparation method. The invention utilizes the phenolic hydroxyl groups in cashew nut shells to react with cyanuric chloride to obtain intermediate 1. Then, the chlorine atoms in intermediate 1 are used to substitute the amino groups in 5-amino-4-hydroxy-1,3-benzenedisulfonic acid to obtain cashew nut shells containing sodium tetrasulfonate. Butyl acrylate, hexyl methacrylate, and cashew nut shells containing sodium tetrasulfonate are copolymerized under the initiation of azobisisobutyronitrile to obtain a modified acrylate polymeric surfactant. Finally, citric acid, sodium citrate, a polymeric film-forming agent, 1,2-propanediol, and the modified acrylate polymeric surfactant are mixed and stirred evenly to obtain the rinse-free, alcohol-free dampening solution. The acrylate polymeric surfactant prepared by this invention, when applied to the dampening solution, can improve the antibacterial and wetting effects of the dampening solution.

This invention belongs to the field of pharmaceutical formulation technology, specifically relating to a transdermal absorption patch for agomelatine and its preparation method. The patch is a pressure-sensitive adhesive dispersion type patch, consisting of a backing layer, a drug-loaded pressure-sensitive adhesive layer, and an anti-adhesion layer. The drug-loaded pressure-sensitive adhesive layer comprises an agomelatine-organic acid eutectic mixture, a non-functionalized polyacrylate pressure-sensitive adhesive containing hexyl acrylate, and a transdermal absorption enhancer. The agomelatine-organic acid eutectic mixture accounts for 5.0-20 wt% of the total weight, the pressure-sensitive adhesive accounts for 70-94 wt%, and the transdermal absorption enhancer accounts for 0.5-10 wt%. The transdermal absorption patch for agomelatine provided by this invention enables 12-hour drug delivery, improves the low bioavailability and poor compliance of existing oral formulations, provides good mechanical adhesion, and enhances medication safety, accuracy, and patient compliance.

The invention discloses a sunscreen cosmetic composition with excellent waterproofness and use feeling and a preparation method of the sunscreen cosmetic composition, and belongs to the technical field of cosmetics. The composition comprises a sun-screening agent, an oil-dispersible film-forming agent and a water-dispersible film-forming agent, the oil-dispersible film-forming agent is selected from one or more of polydimethylsiloxane, organic silicon resin and acrylic acid (ester) / polytrimethylsiloxane methacrylate copolymer; the water-dispersible film-forming agent comprises at least one of an acrylic acid (ester) copolymer and an acrylic acid (ester) / ethyl hexyl acrylate copolymer. Through specific combination and synergistic effect of the two film-forming agents, a compact and breathable composite protective film is formed on the skin surface, and the technical problem that a traditional sunscreen product is difficult to give consideration to high waterproofness and refreshing skin feeling is successfully solved. The composition is in an oil-in-water dosage form, can still keep a relatively high sunscreen index after being soaked in water, and simultaneously endows the skin with an excellent use feeling of lightness and non-stickiness.
