The invention provides 300 DEG C-resistant low-viscosity white ink suitable for handheld equipment, and relates to the technical field of ink materials. The 300 DEG C-resistant low-viscosity white ink applicable to the handheld equipment is prepared from the following materials in parts by weight: 15 to 20 parts of organic silicon resin, 10 to 15 parts of polyester resin, 10 to 12 parts of cross-linking agent, 15 to 20 parts of silicon-aluminum coated rutile type titanium dioxide, 5 to 10 parts of modified nano zinc oxide, 10 to 15 parts of diethylene glycol diethyl ether, 5 to 10 parts of isopropanol, 4 to 6 parts of ethylene glycol monomethyl ether and 5 to 8 parts of functional additive. According to the 300 DEG C-resistant low-viscosity white ink suitable for the handheld equipment, disclosed by the invention, the balance of low viscosity and high temperature resistance is realized by optimizing the components, the proportion and the preparation method of the ink.

The application discloses a negative-electrode-free sodium battery electrolyte and a preparation method and application thereof, and belongs to the battery field.The negative-electrode-free sodium battery electrolyte comprises the following raw materials in parts by weight: 50-80 parts of a linear ether main solvent; 10-30 parts of 1,3-dioxolane cosolvent; 10-17 parts of an electrolyte sodium salt; and 0.3-2 parts of a pyridine boronic acid additive.The pyridine boronic acid additive is at least one of pyridine-3-boronic acid, pyridine-3-boronic acid neopentyl glycol ester and pyridine-4-boronic acid neopentyl glycol ester.The linear ether main solvent is at least one of ethylene glycol dimethyl ether, diethylene glycol dimethyl ether, tetraethylene glycol dimethyl ether, ethylene glycol diethyl ether and diethylene glycol diethyl ether.The negative-electrode-free sodium battery electrolyte can achieve the effects of good first-effect exertion and long cycle life.

The invention relates to a liquid crystal aligning agent, a liquid crystal alignment film, and a liquid crystal display element. Provided are a liquid crystal aligning agent, a liquid crystal aligning film, and a liquid crystal display element which are capable of suppressing poor coating of an aligning film and non-uniformity of display of a liquid crystal display element due to the influence of a wiring structure or C / H, and which are capable of reducing viscosity while maintaining a resin component and a molecular weight. A liquid crystal aligning agent containing: at least one polymer selected from the group consisting of polyimide precursors and polyimides that are imides thereof; and a solvent containing a solvent A, a solvent B, and a solvent C. Solvent A: is selected from the group consisting of N-methyl-2-pyrrolidone, N-ethyl-2-pyrrolidone, [gamma]-butyrolactone, and dimethylimidazolinone. The solvent B is dipropylene glycol dimethyl ether. Solvent C: selected from the group consisting of diethylene glycol diethyl ether and diacetone alcohol.
