The invention discloses ultraviolet cured wood paint and a preparation method thereof. The raw material formula of the ultraviolet cured wood paint comprises the following components in percentage by weight: 30 to 35 percent of modified unsaturated polyester resin, 10 to 20 percent of polyester acrylate, 10 to 15 percent of 1,6-hexanediol diacrylate, 5 to 10 percent oftrimethylolpropane propoxylate triacrylate, 3 to 5 percent of polyhydroxyethyl methacrylate, 0.2 to 0.6 percent of settling agent, 10 to 20 percent of transparent powder, 3 to 6 percent of talcpowder, 0.5 to 1.5 percent of photoinitiator 1, 3 to 5 percent of photoinitiator 2 and 0.2 to 0.6 percent of flatting agent. The ultraviolet cured wood paint can be used as a transparent base coat, is low in cost, simple in preparationmethod and environmentally-friendly, has high transparency, high film performance, high rubbing property and high leveling property, and can create huge economic and social benefit.

The invention provides a dual-network reinforced composite quick-drying gel cement material and a preparation method thereof. The material comprises the following components in parts by weight: 30-40parts of polyhydroxyethyl methacrylate; 35-48 parts of a carbon fiber-organic-inorganic double-network polymer; 15-20 parts of plant fiber; 10-20 parts of bentonite nanoparticles; 10-20 parts of a surfactant; 10-20 parts of graphene; 10-20 parts of hexagonal boron nitride; 2-5 parts of boric acid; 10-15 parts of tricalcium phosphate; 5-10 parts of a redox system initiator; 4-8 parts of a crosslinking agent; and 3-5 parts of a polycarboxylate superplasticizer. The carbon fiber-organic-inorganic double-network polymer produced by using industrial production waste is adapted to graft the plant fiber, and a good graft copolymerization effect with polyhydroxyethyl methacrylate is achieved, the flexural strength and ductility of the synthesized cement material are enhanced, and addition of graphene can make a cement system form a self-monitoring system that monitors various parameters of concrete.

The invention provides a hydrogel dressing and a preparation method thereof. The dressing is prepared from a sea-buckthorn extract, a Chinese atractylode rhizome extract, hyaluronic acid, polylysin, polyhydroxyethyl methacrylate, carrageenan, 2-hydroxyethyl methacrylate, vitamin C, polyvinyl alcohol, calcium chloride, borax, ammonium dihydrogen phosphate, glycerinum, mannose and deionized water. The preparation method comprises the following steps: firstly preparing the sea-buckthorn extract and the Chinese atractylode rhizome extract, respectively, adding such components as hyaluronic acid, polylysin, polyhydroxyethyl methacrylate, carrageenan, 2-hydroxyethyl methacrylate and ammonium dihydrogen phosphate to 1 / 2 parts by weight of ionized water to obtain a mixed liquid I, next, adding such components as vitamin C, polyvinyl alcohol, calcium chloride, borax, glycerinum and mannose to the rest parts by weight of deionized water to obtain a mixed liquid II, and finally, mixing the sea-buckthorn extract, the Chinese atractylode rhizome extract, the mixed liquid I and the mixed liquid II, namely performing a thermal reaction, thereby obtaining the hydrogel dressing. The hydrogel dressing is capable of promoting the healing of a wound, and lasting in antibacterial effect and low in production cost.
