Abstract: A method for manufacturing a transparent heat-insulation building material from waste wood is provided. The method includes the following steps of: step S1, wood pretreatment, drying immersing, heating, adding a complexing agent solution, stirring, then drying the wood; step S2, wood acetylation treatment, loading the wood into a pressure vessel, adding acetylation fluid, reducing the pressure, and then pressurizing and raising a temperature; step S3, resin impregnating, adding a methyl methacrylate monomer solution and heating it, adding the methyl methacrylate monomer and benzoyl peroxide, bleaching the wood by hydrogen peroxide, and placing them in a vacuum permeator to allow the prepolymer liquid to penetrate into the wood and collecting the prepolymer liquid; and step S4, hot press molding polymerizing the wood in an oven and sleeving it into a heat press molding to obtain a densified wood.

Abstract: The present application relates to the technical field of composite film, and more particularly, to a diaphragm composite material and a preparation method thereof. The diaphragm composite material includes a polyethylene naphthalate (PEN) film layer, an aluminum-plated film layer, an aerogel layer, and an elastic adhesive layer disposed between the PEN film layer and the aluminum-plated film layer for bonding the PEN film layer and the aluminum-plated film layer, the aerogel layer is coated on one side of the aluminum-plated film layer away from the elastic adhesive layer. The diaphragm composite layer of the present application has high strength and strong rigidity, has better vibration dampening and noise-reducing effects, and wear-resistant and corrosion-resistant effects, and is worthy of popularization.
