Embodiment Construction

[0011] The non-metallic electrothermal film made of the nanocomposite material provided by the present invention and its preparation method are: use nano-scale graphite carbon powder whose particle fineness averages below 70nm to make low-voltage, low-power electrothermal film, adopt neoprene, Base rubber and other rubbers and polymer vinyl compounds such as polybutadiene and polyisobutylene are used as insulating material carriers; high-voltage and high-power electric heating films and sheets are made of high-temperature resistant epoxy resin, phenolic resin, and polytetrafluoroethylene. Ethylene is used as the insulating material carrier, the epoxy resin type is used as the curing agent, and antimony trioxide (Sb 2 o 3 ) as a flame retardant, uniformly mix according to the ratio of nano-graphite carbon powder (calculated by volume percentage) 36-75%, insulating material 20-60%, curing agent 1-2%, and flame retardant 0.5-2%, and use heat Plastic molding and traditional proce...

Abstract

Proportioning (volume percent) of the composite material is as following: solidified agent 1-2%, flame retardant 0.5-2%, insulation material 20-60%, nano graphite powder 36-75%. Nonmetallic electrothermal film is prepared through thermoplastic molding and traditional technical molding. Characters of the composite material are as following: capability of any folding for many times repeatedly, water washable, high electrothermic conversion efficiency, portable and long service life. Electrical specification of the composite material is as following: AC or DC 1.2-380V, power 1W-3kW, heating temperature 20-85 deg.C and 100-250 deg.C. The composite material is applicable to thermal wear, electric carpet, drying apparatus and other heating elements.

Description

(1) Technical field: [0001] The invention belongs to a novel non-metal heating material electrothermal film made of nanocomposite material and a manufacturing method thereof. (two) background technology: [0002] At present, the heating materials and components commonly used in the market include metal alloy resistance wires, gas discharge heat sources, metal heating elements and some electric heating films. Its disadvantages are that it cannot be folded repeatedly, and it cannot be cleaned with water, and its safety is poor. . The electrothermal film produced by this method overcomes the above-mentioned defects, and is portable, efficient and environmentally friendly, safe and reliable, and can be folded and washed with water repeatedly for many times. According to the search and novelty of Chongqing Science and Technology Information Center, there is no similar product and its processing in China. The method, using this method to process the electric heating film and shee...
