Problems solved by technology

However, the graphene heating film products currently on the market at home and abroad are positioned at the low-temperature far-infrared heating level of graphene (the temperature is generally lower than 200°C), which does not fully exert the electrothermal performance of graphene, and is limited by the quality and advanced nature of graphene. The research and development of graphene slurry technology failed to develop the application of graphene at high temperature and far infrared level

Abstract

The invention relates to graphene composite slurry and a heating coating thereof, and preparation methods thereof, belonging to the technical field of electric heating. According to the invention, theweight percentage of a grinding dispersant in the graphene composite slurry is 1%-5%; the weight percentage of a carrier adhesive in the graphene composite slurry is 10%-80%; a graphene additive accounts for 3%-15% by weight of the graphene composite slurry; and a base material accounts for 16%-70% by weight of the graphene composite slurry. Through improvement of a raw material formula and improvement of a processing technology, the heating temperature of a graphene far-infrared heating technology is increased.

Description

technical field [0001] The invention relates to a graphene composite slurry, a heating coating and a preparation method thereof, belonging to the technical field of electric heating. Background technique [0002] Since its discovery in 2004, graphene has attracted the attention of researchers in various fields around the world. Its excellent electrical conductivity, thermal conductivity, light transmission, flexibility, and super hardness have attracted a large number of scholars and experts in the fields of academia and business to devote themselves to the development and application research of graphene. With the development of graphene preparation technology, the cost problem that limits the application of graphene has become less serious. The large-scale production capacity of graphene has not only increased, but also the cost has plummeted. The industrial application of graphene is also becoming more and more common. After the graphene film is energized, due to Browni...
