A multi-layered structure of at least a polymer base-layer and paint-based protective layer or a paste-based protective layer, the protective layer being non-intumescent, wherein the protective layer exhibits at atmospheric pressure during an increase in ambient temperature, a drop in its thermal conductivity.

An asphaltic sheet comprising an asphaltic component including an asphalt binder and expandable graphite.

A lithium ion battery including a core-shell structured fire extinguishing particle is disclosed. When the battery is overheated to a predetermined temperature, a shell of the fire extinguishing particle coated on one surface or both surfaces of a porous separator is melted, a fire extinguishing material disposed in an inner space of the shell is released into an electrolytic solution of the battery, and as a result, it is possible to prevent the battery from being ignited or exploded even though the battery is overheated. Further, the melted shell clogs pores of the porous separator to block lithium ions from moving, such that the battery is blocked from being driven, thereby preventing the battery from being overheated any more.

A production method for a polyimide with a black resin cured film includes a process of obtaining the black resin cured film by curing a black resin composition on the polyimide. The process of obtaining the black resin cured film includes a process of processing the black resin composition with a predetermined spray impact. A distance from a point where a line that is perpendicular to a surface of the polyimide and that passes through a substrate-adhered edge between the black resin cured film and the polyimide intersects a top portion of the black resin cured film to an edge of the top portion is 25 m or less.

Disclosed is a transparent, flame-retardant thermally-insulating, UV-blocking polymer composite film, comprising sequentially from the top: a flame retardant layer, a base layer, a thermal insulation layer, and a UV-blocking layer, having a total film thickness of 1 m to 500 m, visible light transmittance greater than 80%, UV light transmittance less than 1%, and near-infrared transmittance less than 10%. Also disclosed is a preparation method for the present transparent, flame retardant thermally-insulating, UV-blocking polymer composite film, the technical processes whereof are simple and easy to execute, involve low production costs, and are suitable for industrial mass production. The present transparent, flame retardant thermally-insulating, UV-blocking polymer composite film can be used on such transparent materials and items as glass, windows, protective films, containers and electronic components, and has applications in such fields as construction, transportation, electronics, aerospace and medicine.
