The invention discloses a spherical aluminum oxide coating material for a lithium battery diaphragm and a preparation method of the spherical aluminum oxide coating material, and belongs to the technical field of lithium battery diaphragms.The spherical aluminum oxide coating material for the lithium battery diaphragm comprises, by weight, 40-70 parts of spherical aluminum oxide, 1-10 parts of lithiated PEEK and 50-100 parts of solvent, PEEK of the lithiated PEEK is hyperbranched PEEK, polymeric monomers of the hyperbranched PEEK comprise hexahydric phenol, diphenolic acid and 4, 4 '-dihydroxy-4, 4'-biphenyl. According to the present invention, the surface of the conventional polyethylene diaphragm is coated with the coating material composed of the lithiated PEEK and the spherical alumina particles, such that the electrochemical performance and the stability of the lithium metal battery can be easily improved, and the coating diaphragm has characteristics of excellent thermal stability, excellent wettability and excellent electrolyte absorption rate.

The present application belongs to the technical field of optical cable design and manufacture, and more particularly relates to a high-roundness air-blow micro-cluster optical cable, a design and manufacturing method thereof. The micro-cluster optical cable comprises a cable core, a reinforcing member arranged outside the cable core, and a polyethylene outer sheath. In addition to containing conventional polyethylene sheath material, the polyethylene sheath also contains at least one second polyethylene sheath material which has different shrinkage characteristics from the conventional polyethylene sheath material and is symmetrically arranged inside or outside the polyethylene outer sheath. The shrinkage characteristics of the reinforcing member side sheath material are comparable to the shrinkage characteristics of the non-reinforcing member side sheath material, so that the optical cable tends to be circular after forming.

The application provides an elastic supporting material and a preparation method and application thereof, and the elastic supporting material is prepared from 85-95 parts of low-density high-pressure linear polyethylene, 1.5-2.5 parts of nano filler, 1.5-2.5 parts of plastic lubricant, 3-5 parts of high-density polyethylene, 0.25-0.35 parts of antioxidant, 0.2-0.3 parts of foaming agent, 0.7-0.8 parts of stabilizer and 0.045-0.055 parts of diffusing agent through melting and shaping. Compared with conventional polyethylene type foaming materials, the elastic supporting material has better resilience and softness, and when being used for a hatband core, the hatband core is easy to bend and store, and has good portability.

The present invention relates to a high-temperature, heat-resistant, and oil-resistant food tray paper that is suitable for use in ovens and air fryers and has high recyclability, as well as a method for manufacturing the same. To address the lack of heat resistance and recycling issues associated with conventional polyethylene coatings, the present invention applies a three-stage coating process—undercoating, top coating, and back coating—to the paper. The undercoating secures barrier properties through pigment coating, while the top coating imparts oil resistance and heat resistance by using oil-resistant modified starch and water-resistant surface strength reinforcing additives. The back coating ensures paper curl control and strong water resistance. Through this, the invention provides a disposable food tray paper that can be used stably even at high temperatures of 180°C to 200°C, offers excellent processability such as adhesive bonding, is environmentally friendly based on natural compounds, and is recyclable.

The invention belongs to the technical field of postharvest preservation, and particularly relates to application of a PBAT composite film in waxberry preservation. The invention provides a PBAT composite film for waxberry preservation, which is prepared by taking PBAT and PLA as main raw materials, adding SiO2 (KH560) and ADR4468, and carrying out melt blending, film blowing and other processes. The film is used for packaging and fresh keeping of waxberries, can effectively inhibit fruit rot under a low-temperature storage condition, keeps fruit hardness and soluble solid content, and remarkably prolongs the post-harvest shelf life of the waxberries. Compared with a conventional polyethylene film, the PBAT composite film provided by the invention has better mechanical properties and air and moisture permeability, and is suitable for fresh-keeping packaging of perishable fruits such as waxberries and the like.
