Abstract

The invention discloses a graphene heating coating and a preparation method thereof. The graphene heating coating comprises the following components in percentage by weight: 40%-50% of graphene, 5%-14% of an oxide, 20% of water-based resin, 20%-32% of an adhesive, 0.1%-0.5% of a defoaming agent, 0.3%-0.5% of a coupling agent, and 0.2%-0.5% of a leveling agent. The graphene heating coating providedby the invention is high in electrothermal conversion rate, rapid in temperature rise, long in service life and uniform in heating temperature, and can directly roller-coats or spray-coats positionssuch as walls and ground. The energy utilization rate is improved, and more energy and electricity are saved compared with a traditional heating mode.

Description

technical field [0001] The invention relates to the field of functional coatings, in particular to a graphene heating coating and a preparation method thereof. Background technique [0002] At present, for southern regions that do not adopt central heating, the heating methods usually include air conditioners, floor heating, electric heaters, and coal stoves. The above-mentioned heating methods all need to be processed and formed. Using 220V mains electricity generally has problems such as complicated installation, uneven heating, low thermal efficiency, risk of electric leakage, and poor comfort. For the heating of special-shaped bodies, the operation is complicated. Although the use of carbon fibers is simpler, the cost is quite expensive. [0003] Graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery, and is considered to be a revol...
