Abstract

The invention provides water-based graphene conductive alkyd resin. Ricinoleic acid, neopentyl glycol, trimethylolpropane, m-benzene, trimellitic anhydride, diethylene glycol monobutyl ether, butanol and graphene xylene liquor are used as the raw materials, the mechanical strength and the electric conductivity of a coating prepared through traditional conductive coating paint cannot be easily improved at the same time, the density of the coating is large, and all the problems greatly restrain the application range of the coating. A recently-developed material using graphene as conductive filler can hopefully solve the above problems existing in the conductive coating paint, and the application range and field of the conductive coating paint are greatly widened. However, graphene cannot be dispersed in a water-based system easily in general, and thus the graphene is evenly dispersed in water-based alkyd resin through resin synthesis. High-performance conductive coating paint can be prepared through the resin. The problems that the mechanical strength and the electric conductivity of the coating prepared through the traditional conductive coating paint cannot be easily improved at the same time, and the density of the coating is large.

Description

technical field [0001] The invention relates to an organic compound, in particular to a water-based graphene conductive alkyd resin and a preparation method thereof. Background technique [0002] Graphene is a new material because of its low density and high mechanical strength. In addition, its carrier mobility reaches 200000cm2V -1 the s -1 , more than 10 times the mobility of commercial silicon wafers, and has a higher conductivity than silver. At present, conductive coatings mainly use conductive fillers, and conductive fillers mainly include metal systems, metal / glass composites, and carbon systems. Water-based alkyd resin is a common water-based resin and an important raw material for the preparation of conductive coatings. Water-based graphene alkyd resin has not been reported in the literature. 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 ...
