NOVELTY - Multi-wall carbon nano-tube heat-resistant coating comprises 10-80 pts. wt. multi-wall carbon nanotubes, 10-50 pts. wt. low-density oxidation graphene, 5-25 pts. wt. dispersant, 10-150 pts. wt. aqueous binder, 25-250 pts. wt. carbon fiber and 600-1500 pts. wt. pts. deionized water. USE - Multi-wall carbon nano-tube heating coating used for family, commercial building and heating in industrial building. Uses include but are not limited to electric heating wire heating, halogen tube heating, quartz tube heating and heat conducting oil heating. ADVANTAGE - The coating is low resistance, low voltage heating, fast heating speed, high heating power, heating in infrared radiation way, is convenient to design and construct, and can be maintained and installed. It can be flexibly applied to more space scene. It has good quality control program and good flexibility, improves the product yield and effectively processing the quality of the product. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation method of multi-wall carbon nanotube heat-resistant coating comprising: (1) adding dispersant into the deionized water, stirring uniformly, adding multi-wall carbon nano-tube and low density graphene, stirring uniformly to form multi-wall carbon nano-tube and low density graphene dispersion; (2) grinding and dispersing the multi-wall carbon nano-tube and low-density graphene dispersion liquid by grinding device, controlling the grain diameter below 15 microns; adding 200-700 pts. wt. deionized water, stirring uniformly to obtain suspension A; (3) adding aqueous binder in the suspension A, stirring uniformly to obtain suspension B; (4) adding carbon fiber in the suspension B, stirring uniformly to obtain suspension C; and (5) grinding and dispersing the suspension C by the grinding device; controlling the grain diameter below 10 microns; and obtaining the finished product.
