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.
