Intelligent temperature-adjusting aluminum honeycomb composite board based on phase-change material and manufacturing process of intelligent temperature-adjusting aluminum honeycomb composite board

Abstract

The invention discloses an intelligent temperature-adjusting aluminum honeycomb composite board based on a phase-change material and a manufacturing process of the intelligent temperature-adjusting aluminum honeycomb composite board, and relates to the field of building energy conservation. The phase change material provided by the invention is prepared by taking graphene composite cellulose and hydroxyethyl methylacrylate as raw materials, carrying out freeze molding, freeze drying and thermal crosslinking treatment to form composite cellulose aerogel, and then carrying out vacuum impregnation on polyethylene glycol, the graphene composite cellulose is prepared by reacting amino cellulose with epoxy functionalized graphene and an epoxidized polymer, so that a heat-conducting path of graphene and a rigid and heat-resistant structure of the polymer are synchronously introduced; an aluminum honeycomb panel is filled with the phase change material, and the intelligent temperature adjusting composite board is prepared through pressing. The phase change material prepared by the invention has low leakage rate, high heat conductivity coefficient and excellent mechanical properties, and is suitable for the field of building energy conservation.
