Nanometer material electrothermal film

Abstract

The invention relates to an efficient energy-saving novel nanometer material electrothermal film which comprises (mass percentage): 10-25% of tin chloride, 2-8% of nickel chloride, 10-20% of ferric oxide, 5-10% of titanium tertrachloride, 2-5% of sodium chloride, 10-15% of stannic oxide, 5-10% of hydrochloric acid, 5-15% of glycerol and 20-40% of ionized water. Electrothermal film processing liquid is prepared by mixing, stirring and heating tin chloride, nickel chloride, ferric oxide, titanium tertrachloride, sodium chloride, stannic oxide, hydrochloric acid, glycerol and ionized water at high speed. Then physical vapor deposition (PVD) technology is used for depositing the electrothermal film processing liquid on a base material to form the nanometer electrothermal film, and then a nanometer electrothermal film end product is obtained by coating silver oxide slurry at two ends of a nanometer electrothermal film semi-product and baking. The efficient energy-saving novel nanometer material electrothermal film is high in working temperature, wide in application range, long in service life, high in cost performance and efficiency and simple in manufacture method.

Description

technical field [0001] The invention relates to the research and development of a high-efficiency and energy-saving novel nanometer material heating body, and belongs to the technical field of semiconductor heating. Background technique [0002] Nano electrothermal film heating element belongs to planar heating, its electrothermal efficiency is about 30% higher than that of ordinary resistance heating element, and its heating speed is fast. At the same time, it has the function of far infrared radiation heating and has the effect of physiotherapy; but there are three common problems in other invented electrothermal film : 1. The combination between the electrothermal film and the base material is not very good, and it is easy to cause defilming phenomenon if it is used for a long time; 2.

[0002] Nano electrothermal film heating element belongs to planar heating, its electrothermal efficiency is about 30% higher than that of ordinary resistance heating element, the heating speed is fast, and it has the function of far infrared radiation heating at the same time, and has the effect of physiotherapy; but there are three common problems in other invented electrothermal film : 1. The combination between the electrothermal film and the base material is not very good, and it is easy to cause defilming phenomenon if it is used for a long time; 2. The production process of the electrothermal film is complicated or the use of expensive raw materials is not cost-effective; 3. The vast majority in the market Most electrothermal films only reach the micron level, and their operating temperature and operating voltage are more restricted, and their application range is narrow

The defects in these three aspects lead to certain difficulties in the performance and promotion of the electric heating film
