Abstract

The invention discloses a foamed aluminum composite porous material and a preparation method thereof. The foamed aluminum composite porous material comprises open-cell foamed aluminum and a porous filler filled in the pores of the foamed aluminum and formed by chemical foaming, wherein the filler at least comprises 40-60 weight parts of recycled foaming polyurethane, 50-60 weight parts of low-density polyethylene, 0.6-0.7 weight part of dicumyl peroxide, 2-4 weight parts of azodicarbonamide, 0.7-0.9 weight part of zinc oxide and 1-2 parts of zinc stearate, and is formed by foaming in the pores of the foamed aluminum. The preparation method comprises the steps of blending the mixture at 130-140 DEG C; plasticizing and cutting into particles; mixing at 130-140 DEG C, and tabletting to obtain an un-foamed material; feeding the un-foamed material into the pores of the foamed metal, and maintaining pressure at 4-5MPa at 180-195 DEG C for 8-10 minutes for a chemical foaming reaction; releasing the pressure so that the filler is sufficiently foamed; cooling to obtain the composite porous material.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to an aluminum foam high molecular polymer composite material; the invention also relates to a production method of the aluminum foam high molecular polymer composite material. Background technique [0002] With the increasing popularity of white goods, a large number of waste polyurethane plastics produced by air conditioners and refrigerators are seriously polluting the living and surrounding environment. The disposal of waste polyurethane is imminent, and its recycling and application have always been research hotspots at home and abroad. [0003] Metals containing voids are called foamed metals or foamed metals, such as foamed aluminum, foamed nickel, foamed copper, etc. Foamed aluminum is made by adding additives to pure aluminum or aluminum alloy and undergoing a foaming process. Because of its special loose pore structure, low density, light weight, large specific...
