Composite low-voltage electrothermal film and making method

Abstract

The structure of the complex low-voltage electric heating film (CLEHF) consists of the electric heating inorganic compound (EHIC), the hi-temperature durable (HTD) isolator, the electrodes and the anti-oxidation HTD isolation layer. The EHIC consists of the carbon system inorganic material, the rare-earth material, the metal oxide, the inorganic compound and the polymerization liquid medium adhesive. The manufacture technology of CLEHF includes: ingredient configuring, mixing, skiving, spraying, solidifying and forming. With a low work voltage of 12 volts, CLEHF heats up to 100 degrees centigrade in only 50 seconds. This invention possesses advantages of fast response time, high heating efficiency and wide application range. Depending on different features and usages of various heater bodies, different materials are selected to form different shapes of heating films. Therefore, this heating film adapts to all handy low voltage electric heating apparatuses.

Description

technical field [0001] The invention relates to a composite low-voltage electric heating film and a manufacturing method thereof, belonging to a manufacturing method of an electric heating device. In particular, it relates to a composite low-voltage electrothermal film for low voltage below 12 volts. Background technique [0002] At present, in many fields such as household appliances and industrial appliances, electric heating products are more and more widely used. There are many restrictions on the application of these electric heating products, which are mainly used in high voltage applications. Due to the large resistance value, high voltage is required, and the safety of high voltage is poor, and there is a danger of leakage. Due to the need for insulation, there are many heat-conducting layers, the temperature rises slowly when starting up, the material is thick, and the product is heavy. It is difficult to process small and special-shaped products, and the comfort i...

There are many restrictions on the application of these electric heating products, mainly in high-voltage applications. Due to the large resistance value, high voltage is required, and high-voltage safety is poor, and there is a danger of leakage

Due to the need for insulation, the number of heat-conducting layers is large, the temperature rises slowly when starting up, the material is thick, and the product is heavy. It is difficult to process small and special-shaped products, and the comfort is poor. It is difficult to make special-shaped products.

General electrothermal materials can also be used in low voltage, but they have great control over the low voltage of low voltage. It needs to be above 12 volts or its power should be large, so it is very important for the design of products that people can carry with them in their daily life. There are limitations, and the response speed is not fast enough at low voltage heating temperature, the heating temperature is not high enough, the volume is large, and it is not light and compact enough
