A virus inactivator composition, characterized in that it contains: (a) 0.01% to 5.0% by mass of a cationic virus inactivating component as a virus inactivating component; (b) 0.02% to 10.0% by mass of one or more selected from fumaric acid, phosphoric acid, lactic acid and citric acid as a virus inactivation efficacy enhancing component; and water.

The invention is applicable to the technical field of materials, and provides a polyacrylate dispersion, a preparation method and a water-based paint.The preparation method comprises the steps that a low-boiling-point solvent, an acrylate monomer and an initiator are added into high-pressure equipment for a reaction, and polyacrylate resin is obtained; under the condition of 50-75 DEG C, slowly pumping a neutralizer into the polyacrylate resin through a high-pressure pump to neutralize the polyacrylate resin for 30-50 minutes, and adding water to disperse the polyacrylate resin, so as to obtain the product. The neutralizer is obtained by compounding ammonia water and organic amine according to the mass ratio of 1: (0-6). Polyacrylate resin is preliminarily obtained through high-pressure equipment, a low-boiling-point solvent and an acrylate monomer, and the polyacrylate resin is neutralized through a composite neutralizer of ammonia water and organic amine to obtain the polyacrylate dispersion containing a large number of rigid rings and active hydroxyl groups. After being prepared into paint, the paint is matched with a water-based isocyanate curing agent, so that the paint has remarkable quick-drying performance and high-gloss and high-fullness characteristics, and the industrial production efficiency is greatly improved while the application scene of quick surface drying is met.

The utility model relates to a sun-proof quick-dry cool-feeling yarn which is of a bi-component skin-core structure, the bi-component skin-core structure comprises a core layer and a skin layer, the core layer is made of PA materials and has high specific heat capacity, so that the specific heat capacity of the yarn is greatly improved, and the PA materials have soft performance, so that the yarn has good softness while keeping cool feeling; the skin layer is made of a PET (Polyethylene Terephthalate) material, has excellent quick-drying performance and can quickly disperse moisture, so that the skin sticking phenomenon caused by sweating is avoided; the heat-conducting particles are added into the skin layer, so that the heat-conducting property of the skin layer is improved, the heat-conducting property of the yarn is remarkably enhanced, and the yarn has a more lasting and cool touch feeling by combining the heat-conducting particles with the PA with high specific heat capacity of the core layer; the nano-scale heat-conducting particles uniformly dispersed in the skin layer can reflect sunlight, reduce the absorption of sunlight heat energy by the yarn, improve the sun-screening performance of the fabric, play the antibacterial role of the nano-material, and solve the problems that a traditional after-finishing sun-screening agent is easy to fall off and the antibacterial effect is invalid.

The invention belongs to the technical field of coatings, and particularly relates to a preparation method of a low-temperature-resistant moisture solvent-free anticorrosive coating for a moon platform pillar of a railway station, which comprises the following steps: in a reaction kettle, adding hydroxyl-terminated epoxy butyronitrile resin into micromolecular epoxy resin, and stirring for 1 hour at the temperature of 45-55 DEG C to obtain composite toughened epoxy resin; putting an acrylic acid dispersing agent into a liquid feeding mechanism, adding the acrylic acid dispersing agent into the composite toughened epoxy resin, stirring for 20-40 minutes, adding an organic silicon defoaming agent, and stirring for 30 minutes; finally, the quick lime and the pigment in the two feeding mechanisms are added into the reaction kettle and stirred for 1.5-2 hours at the temperature of 45-65 DEG C, and a component A is obtained through a screen of the screening mechanism; in a reaction box, bisoxazolidine is added into low-molecular polyether amine and stirred, and finally a component B is obtained through a screen of a screening mechanism; compared with the prior art, two components can be processed and prepared at the same time, the two components can be stored while the preparation efficiency of the coating is improved, and convenient use of the coating is achieved.

This invention discloses a fast-drying waterborne polyurethane resin, its preparation method, and its application. By weight, it comprises the following components: 30-40 parts of self-made polyester polyol, 30-50 parts of polyether polyol, 2-5 parts of chain extender, 1-3 parts of hydrophilic monomer, 1-3 parts of trimethylolpropane, 40-60 parts of isocyanate, 1.1-1.5 parts of neutralizer, and 50-80 parts of solvent. This fast-drying waterborne polyurethane resin utilizes self-made branched polyester and polyether to construct flexible segments that combine rigidity and flexibility. Low hydrophilic monomer content enables self-emulsification and ensures water resistance. Trimethylolpropane and self-made polyester polyol form a double crosslinking network with built-in branching points. Isocyanate compounding balances hardness and pot life. The high R-value design allows residual NCO to naturally generate urea bonds during emulsification, compensating for the emulsification difficulties caused by low hydrophilicity. Ultimately, it achieves a balance between fast drying and high water resistance without the addition of external drying agents or amine-based chain extension. It combines fast drying, high water resistance, and excellent mechanical properties. The process is simple and low-cost, making it highly valuable for industrial promotion.
