Description

technical field [0001] The invention relates to the technical field of graphene, in particular to an aqueous slurry for a graphene far-infrared planar heating element. Background technique [0002] Conductive paste refers to a new type of functional coating that can be applied to insulating substrates by various spraying methods, so that it has the ability to conduct current and eliminate the accumulated static charge. At present, conductive coatings can be divided into structural types according to the conductive mechanism and composition. Conductive coatings and additive conductive coatings, conductive coatings can be divided into two types: structural type and blending type. Due to the complex process and high price of structural conductive coatings, blended conductive coatings have become the focus of research and development and industrialization of conductive coatings. However, the problems of high cost, high density and serious pollution of blended conductive coatings...

Problems solved by technology

Due to the complex process and high price of structural conductive coatings, blended conductive coatings have become the focus of research and development and industrialization of conductive coatings. However, the problems of high cost, high density and serious pollution of blended conductive coatings still need to be solved further solution

[0003] There are also people who use graphene to prepare conductive paste, but now most of the graphene conductive pastes on the market are oily pastes. During the production process, oily pastes volatilize a large amount of harmful substances, which have a strong smell and serious pollution. With the development of the national economy Development and technological progress, improving people's livelihood, protecting the environment, saving resources, saving energy and reducing emissions, and developing a circular economy have become my country's basic national policies
