Abstract

The invention provides a novel nano-carbon crystal electric strip heating floor and a preparation method thereof. The method is as follows: (1) dissolving nano-short carbon fibers in an alkaline solution, separating them after ultrasonic treatment, and placing them in 1-3mol / L In the ammonium bicarbonate solute, after anodic oxidation surface treatment, take it out and clean it with ethanol, dry it, place it in a high-energy ball mill and pulverize it to obtain the modified nano-carbon crystal; (2) the modified nano-carbon crystal and graphite powder Add additives, mix and grind, and add plant puree, stir evenly through a homogenizer, heat and pressurize to obtain a planar modified nano-carbon crystal heating material; (3) the planar modified nano-carbon crystal heating material The metal sheet electrodes are fixed with silver solution at both ends, and a temperature control device is installed to solidify to form a carbon crystal heating layer; (4) in the order from bottom to top, the solid wood base layer, polyester resin insulating layer, carbon crystal heating layer, all The reflective aluminum layer and the solid wood surface are cut to a suitable size, and then composited to form a nano-carbon crystal electric strip for heating the floor.

Description

Technical field: [0001] The invention belongs to the technical field of electric heating floors, and in particular relates to a novel nano-carbon crystal electric strip heating floor and a preparation method thereof. Background technique: [0002] With the continuous development of science and technology, traditional heating methods such as electric boilers and electric heaters have been gradually replaced by relatively mature new forms such as electric heating film and heating cables. Due to the unique advantages of point heating, domestic research on electric heating has become more and more in-depth. Various, and are being gradually applied to building heating. [0003] Carbon crystal electric heating floor heating system is an electric heating product made of carbon crystal heating material. It uses a flat plate made of short carbon fiber as a heating element. Combined together to make a planar heating plate. When the planar heating plate is powered on, the carbon cry...
