Abstract

The invention relates to waterborne CNTs (carbon nanotubes)-graphene composite wire dye paste, a waterborne CNTs-graphene composite heating wire and waterborne CNTs-graphene composite heating cloth. The waterborne CNTs-graphene composite wire dye paste is prepared from, by mass, 0.01-35 parts of waterborne graphene solution, 50-70 parts of waterborne carbon nanotube solution, 0.01-1 part of an antifoaming agent, 0.01-1.5 parts of a wetting agent, 5-30 parts of resin and 0.01-5 parts of a thickening agent. The waterborne CNTs-graphene composite heating wire is coated with the waterborne CNTs-graphene composite wire dye paste. The waterborne CNTs-graphene composite heating cloth comprises the waterborne CNTs-graphene composite heating wire. The waterborne CNTs-graphene composite wire dye paste is small in particle size range and uniform in conductivity, the average particle size is about 1micron, a resistance range of a graphene wire formed by coating of a wire with the wire dye paste is200 ohm / cm-300 ohm / cm, the waterborne CNTs-graphene composite heating cloth formed by the CNTs-graphene composite heating wire is uniform in heating, and the temperature difference of per square meter of the heating cloth is smaller than 5 DEG C.

Description

technical field

[0001] The invention relates to the fields of carbon nanotubes (hereinafter referred to as CNTs) and graphene heating, in particular to water-based CNTs-graphene dyeing thread slurry, heating wires and heating cloths. Background technique

[0002] Existing heating cloths often have uneven heating and have a strong smell. The main heating structure of the heating cloth is mainly the heating wire woven inside the heating cloth, and the existing heating wire has a large resistance value, or when the resistance value is small, there is a phenomenon of uneven resistance value of a single wire, and the current type of heating wire Basically, they are oil-based graphene heating wires composed of a single graphene. The existing graphene heating wire dyeing slurry is generally oily graphite-related slurry, the size of the slurry is large, the resistance is 150-750Ω / cm, and the resistance fluctuates in a large range, resulting in uneven heating and a strong smell.
