Abstract

The invention discloses a preparation method of a composite material of epoxy resin and closed-cell foamed aluminum, and relates to a composite material which is formed by a high polymer material and a foamed metal material. The preparation method comprises the following steps of: degreasing and decontaminating closed-cell foamed aluminum pieces by using 0.1mol / L of sodium hydroxide alkali liquid; neutralizing the alkali liquid on the closed-cell foamed aluminum pieces by using 0.01mol / L of hydrochloric acid; mixing the epoxy resin E-44 and a curing agent according to a mass ratio of 1:1; proportioning the closed-cell foamed aluminum pieces and the epoxy resin with the curing agent in a mold in a water bath at 70 DEG C according to a volume ratio of 1:1 or 3:1; after bubbles float up, taking out the mold from the water bath; standing for one week at normal temperature so as to obtain a dispersed embedded type epoxy resin and closed-cell foamed aluminum material. By utilizing the method, the defects that the conventional foamed aluminum-based composite material is low in yield strength, resource and energy are wasted in production, the cost is high and the environment can be polluted, are solved.

Description

technical field [0001] The technical solution of the invention relates to a composite material formed of a polymer material and a metal foam material, specifically a preparation method of a composite material of epoxy resin and closed-cell aluminum foam. Background technique [0002] Although the damping performance of polymer materials is better than that of aluminum foam, in terms of mechanical properties, the strength of metal materials is much higher than that of polymer materials. For this reason, the research on metal foam with damping performance has gradually matured in recent years. The research and application of metal foam composite materials with damping properties, especially the research work on aluminum foam composite materials filled with polymer materials has been developed. This kind of composite material composed of aluminum foam filled with polymer phase is expected to combine the advantages of both to obtain a new type of aluminum foam composite material...
