Abstract

The invention discloses water-based graphene conductive polyester resin and a preparation method thereof. According to synthesis operation steps and a formula of the water-based graphene polyester resin, graphene is introduced into a system by starting from resin synthesis and is evenly dispersed into water-based resin, thus improving electric conduction and heat conduction capabilities of water-based polyester resin per se, and solving the problems existing in traditional coating materials. The water-based graphene conductive polyester resin prepared by the method has high electric conduction and heat conduction capabilities, great market potential and wide prospect.

Description

technical field [0001] The invention belongs to the field of organic synthesis, more specifically, the invention relates to a water-based graphene conductive polyester resin and a preparation method thereof. Background technique [0002] Water-based polyester resin is a common water-based resin and an important raw material for the preparation of conductive amino baking varnish coatings. With traditional conductive coatings, it is difficult to increase the mechanical strength and electrical conductivity of the coating at the same time, and the density of the coating is relatively high. These problems greatly limit its application range. And recently developed, therefore, using graphene as a conductive filler is expected to solve the problems of the above-mentioned conductive coatings, and greatly expand the application range and field of conductive coatings. However, graphene is generally difficult to disperse into water-based systems, and water-based graphene polyester res...
