Abstract

The invention provides an environment-friendly and simple method for preparing graphene and epoxy resin composite foam material by single-component foaming, comprising: allowing N-aminoethylpiperazine (AEP) and CO2 to react to obtain a latent curing-foaming agent (B-AEP); ball-milling epoxy resin and graphene, ultrasonically dispersing at 55-60 DEG C for 30-35 min, cooling to room temperature, adding the curing-foaming agent and a foam stabilizer, stirring to obtain single-component foam, pouring into a preheated mold, and curing at 120-125 DEG C to obtain the graphene and epoxy resin composite foam material. The prepared foam material has excellent storage stability, good foam pore structure, excellent compressibility and good antistatic property.

Description

technical field [0001] The invention belongs to the technical field of preparation of epoxy resin foam materials, and in particular relates to a single-component foamed graphene epoxy resin composite foam material and a preparation method thereof. Background technique [0002] Due to its light weight, high strength, good thermal stability and good chemical stability, epoxy foam materials are widely used in sandwich composite materials, transportation, high-strength floating materials, foam packaging and other fields. Existing epoxy resin foams are usually prepared by adding physical blowing agents or chemical blowing agents, such as trichlorofluoromethane and azodicarbonamide. The natural source of these blowing agents is petrochemical raw materials, which not only increases the burden of petrochemical energy exploitation, but also has certain damage to the atmospheric environment. At this stage, the use of environmentally friendly blowing agents has become the mainstream, ...
