Abstract

The invention discloses a high-barrier, flame-retardant and anti-electrostatic epoxy-resin adhesive and a preparation method and application thereof. The adhesive is prepared from the following ingredients in parts by weight: 100 parts of epoxy resin, 4-10 parts of ethylene-vinyl alcohol copolymer, 50-70 parts of polyamide resin, 0-10 parts of thermoplastic polyurethane, 20-30 parts of N-methyl pyrrolidone, 0.5-2.5 parts of antistatic agent, 2-4 parts of modified nano organic montmorillonite, 1-3 parts of modified nano-silica, 14-20 parts of di-n-butyl phthalate, 3-5 parts of inorganic filler and 14-20 parts of dimethyl methyl phosphonate. The adhesive prepared by the preparation method has the advantages of good electrostatic resistance, high barrier, excellent flame retardance, high adhesive strength, good toughness, strong deflection resistance and the like, and the preparation method is scientific and reasonable and is simple in process and strong in operability, so that the industrial production is easy to realize. The adhesive can be applied to fields with relatively high requirements for electrostatic resistance, barrier and flame retardance, such as the combination of plastic fuel tank materials and PET (Polyethylene glycol Terephthalate) beer bottle materials, which is relatively popular currently.

Description

technical field [0001] The invention belongs to the technical field of epoxy resin adhesive preparation, and in particular relates to a high-barrier flame-retardant antistatic epoxy resin adhesive and a preparation method and application thereof. Background technique [0002] Epoxy resin adhesive is an important one among the eight synthetic adhesives. It is widely used in aerospace, automobile, chemical industry, electronic appliances, light fields of work and daily life. Generally, epoxy resin adhesives are mainly composed of epoxy resin and curing agent. We can add tougheners, diluents, coupling agents, accelerators, inorganic fillers, etc. as needed. The bonding process of epoxy resin adhesives is a complex physical and chemical process, including steps such as infiltration, adhesion, and curing, and finally generates a cured product with a three-dimensional cross-linked structure to combine the adherend into a whole. Bonding performance (strength, heat resistance, cor...
