A method of making a lightweight thermal shield that includes obtaining a mold having a shaped support screen with a molding surface configured to allow the passage of air and moisture therethrough, and with the mold being adapted for drawing a vacuum from behind the support screen. The method also includes applying a wet insulation material onto the molding surface of the support screen and drawing a vacuum to withdraw moisture through the support screen and consolidate a layer of insulation material on top the molding surface. The method further includes removing the consolidated layer of insulation material from off the molding surface, installing the consolidated layer of insulation material into an outer shell layer, and drying the consolidated layer of insulation material within the outer shell layer to form a lightweight core insulation layer.

A method of preparing an elastomer membrane with high water pressure resistance includes the following steps: preparing a dry material by subjecting first thermoplastic polyurethane (TPU) powder/particles to a drying treatment; preparing a first mixture by mixing the dry material thoroughly with one or a mixture of at least two of diethylenetriamine, diethylaminopropylamine, and diaminodiphenylmethane; preparing a second mixture by mixing an initiator thoroughly with the first mixture; preparing a first membrane layer from the second mixture; and preparing a second membrane layer and a third membrane layer through the above steps such that the second membrane layer and the third membrane layer are sequentially formed on the first membrane layer.

A gypsum board manufacturing method is provided. The gypsum board manufacturing method includes a molding step of forming a plate-shaped molded body including gypsum slurry and cover base paper disposed to cover at least a part of a surface of the gypsum slurry. In a cross section orthogonal to the longitudinal direction of the molded body, the cover base paper completely covers the periphery of the gypsum slurry, portions of the cover base paper overlap each other, and a distance between a step formed by the overlap of the cover base paper and a lateral end of the molded body is greater than or equal to 15 mm.

The present invention discloses a polyimide-based composite carbon film with high thermal conductivity and a preparation method therefor. The preparation method includes: uniformly coating the surface of a polyimide-based carbon film with an aqueous graphene oxide solution, and then covering the same with another polyimide-based carbon film uniformly coated with an aqueous graphene oxide solution; repeating such operation; after the polyimide-based carbon films are dried, bonding the polyimide-based carbon films by means of graphene oxide so as to form a thick film; bonding the polyimide-based carbon films more tightly by means of further low-temperature hot pressing; and finally, obtaining a thick polyimide-based carbon film with high thermal conductivity by repairing defects by means of low-temperature heating pre-reduction and high-temperature and high-pressure thermal treatment. The thick polyimide-based carbon film with high thermal conductivity has a thickness greater than 100 m and an in-plane thermal conductivity of even reaching 1700 W/mK or above.
