Abstract

The invention discloses iron-nickel mixed liquid-state metal epoxy resin and a preparation method thereof. The iron-nickel mixed liquid-state metal epoxy resin is prepared from the following raw materials including iron ion liquid, nickel ion liquid, dispersing agents, bisphenol-A epoxy resin and curing agents. The preparation method comprises the following steps of S1, mixing iron ion liquid andnickel ion liquid to obtain a mixture A; S2, adding dispersing agents into the mixture A; performing stirring and ultrasonic dissolution; obtaining a mixture B after the dispersing agents are completely dissolved; S3, adding the mixture B into the bisphenol-A epoxy resin; performing stirring in a negative pressure state to obtain a mixture C; S4, adding curing agents into the mixture C; performingstirring; obtaining the iron-nickel mixed liquid-state metal epoxy resin. The epoxy resin provided by the invention has the advantages that the formula is reasonable; the preparation process is simple; the prepared product can passivate electromagnetic waves; when the iron-nickel mixed liquid-state metal epoxy resin is applied to the wave filtering material, the wave filtering frequency is 5GHz to 20GHz.

Description

technical field [0001] The invention relates to the technical field of epoxy resins, in particular to an iron-nickel mixed liquid metal epoxy resin and a preparation method thereof. Background technique [0002] Epoxy resins are widely used in daily human life, and bisphenol A epoxy resin is the most commonly used epoxy resin. By reacting with a curing agent, the epoxy resin can form a three-dimensional cross-linked polymer network, and then the network structure is cured to obtain a shaped product of the epoxy resin. Epoxy resins are widely used in coatings, adhesives, molding various electronic devices, integrated circuit packaging materials, and parts and products in the circuit board manufacturing industry, such as soda cans for acidic beverages and civil construction The structure is supplemented with a tank for strengthening additives. Moreover, epoxy resin can also be used in combination with carbon fiber or glass fiber to become a reinforcing material with extremel...
