The application provides a highly fluorinated flame-retardant electrolyte additive, a preparation method, a highly fluorinated flame-retardant electrolyte and application thereof in lithium batteries, and the preparation method comprises the following steps: dissolving phosphorus trichloride in a solvent and cooling to 0-5 DEG C, then adding tert-butyl alcohol and stirring, then adding trifluoroalcohol and reacting to obtain intermediate product A; then, under a nitrogen atmosphere, adding the intermediate product A into a tert-butyl alcohol potassium solution in anhydrous dimethyl sulfoxide and reacting to obtain intermediate product B; finally, under a nitrogen atmosphere, adding dichloroalkane into the intermediate product B and reacting and purifying to obtain the highly fluorinated flame-retardant electrolyte additive. The flame-retardant electrolyte additive has good compatibility with lithium salt and organic solvent, and has high contents of fluorine and phosphorus flame-retardant elements. The additive can be used together with lithium salt and organic solvent to construct a flame-retardant electrolyte for lithium batteries, and can effectively reduce the flammability of the electrolyte and enhance the safety performance without sacrificing the efficiency and performance of the electrolyte.

The invention provides black paste for labor protection gloves and a preparation method of the black paste, and belongs to the technical field of preparation of labor protection appliances, an anionic surfactant in the black paste has good permeability, and can accelerate the exchange speed of a solvent and water in the black paste and improve the brightness; the added dispersing agent can avoid flocculation of carbon black particles, stability of the color paste is improved, in addition, the amine value of the color paste is low, and the viscosity cannot be affected under the high-temperature condition; the adopted hydroxyl acrylic acid modified polyurethane contains COOH, OH, benzene ring and other pigment affinity groups, has the advantage of high gloss, and also has certain dispersion and viscosity reduction functions. The black paste provided by the invention is wide in raw material source, low in price, simple in production process and low in cost, and the prepared black paste has the characteristics of high blackness, high brightness, high solid content, low viscosity, low odor and good wear resistance, and has good application prospects and popularization values.

This application relates to the technical field of fiberglass reinforced plastics (FRP), and in particular to an unsaturated polyester resin for FRP, a method for preparing the same, and FRP. The unsaturated polyester resin comprises the following raw materials in parts by weight: diols: neopentyl glycol 22-30 parts, 2,2-diallyl bisphenol A 2-4 parts, and bisphenol fluorene 5-9 parts; diacids: isophthalic acid 5-15 parts, terephthalic acid 5-15 parts; acid anhydrides: phthalic anhydride 3-15 parts, maleic anhydride 5-17 parts; toughening agent: double-ended hydrogen-capped silicone oil 5-9 parts; platinum catalyst: the amount of platinum catalyst added is 30-150 ppm of the total mass of 2,2-diallyl bisphenol A and double-ended hydrogen-capped silicone oil; diluent 25-45 parts; polymerization inhibitor 0.01-0.06 parts. It has the advantage of improving the hardness and toughness of the unsaturated polyester resin, thus enhancing its corrosion resistance.
