This invention relates to the field of coating technology, and proposes a high weather-resistant alkyd protective coating and its preparation method. The alkyd protective coating comprises the following components in parts by weight: 45-55 parts alkyd resin, 20-42 parts methylphenyl silicone resin, 10-25 parts carbon nanotubes, 1-2 parts dispersant, 0.5-1.5 parts anti-settling agent, 1-2 parts drying agent, and 15-20 parts solvent. This technical solution solves the problems of poor weather resistance and flexibility caused by poor tensile properties, poor low-temperature flexibility, and poor aging resistance in related technologies of alkyd protective coatings.

This invention relates to the field of electrochemical energy storage materials and lithium metal battery technology, specifically to an in-situ polymerized solid electrolyte, its preparation method and application, and lithium metal batteries. This in-situ polymerized solid electrolyte is prepared by heating a ring-opening polymerization reaction using 1,3-dioxolane and 1,1,1-trifluoro-2,3-epoxypropane as reactants, sodium thiosulfate as an initiator, and lithium salt and plasticizer fluoroethylene carbonate as a precursor solution. This electrolyte possesses numerous amorphous regions, which is beneficial for ion transport, enabling the formation of a self-supporting dense structure. It also ensures close contact with the electrode, resulting in a pure interface that effectively reduces interfacial impedance and avoids side reactions at the electrode interface. Furthermore, it enhances oxidation resistance, broadens the electrochemical window, and inhibits dendrite growth. While achieving good mechanical properties, it also improves the cycle stability and safety performance of the battery. It has excellent application prospects in lithium metal batteries, lithium-ion batteries, solid-state energy storage systems, or flexible electronic devices.
