Problems solved by technology

[0002] At present, most of the heating materials used in daily life are traditional electric heating wires, silicon carbide and more advanced PTC ceramic heating elements, and carbon fibers that have recently appeared on the market. Most of these heating materials are hard and brittle in texture, large in size, wide in thickness, The service life is short, cut into several heating pieces, the heating density is uneven, especially used for medical hot compress, cold-proof clothing, industrially used for precision electronic instruments, aviation and other high-end technical products are more heavy and clumsy, there are Great limitations, do not meet the requirements of energy saving and thermal efficiency improvement

Embodiment approach 1

[0025] A preparation method for printing a heat-generating flexible transparent film with silver paste and carbon paste, the steps are as follows:

[0026] 1. Preparation: carbon paste, conductive silver paste, TIE transparent plastic film with a thickness of 0.02-0.05, and nylon mesh with a mesh number of 200; the high temperature resistance of the TIE transparent plastic film is 160°C.

[0027] 2. To prepare high-performance plasma ink, first select highly conductive carbon paste: the mesh fineness of graphite powder is 99.9%, conductive silver paste: the mesh fineness of silver powder is 99.9%,

[0028] 1) The weight percentage distribution of graphite carbon is as follows: silicone rubber emulsion 56%, accelerator 2%, antioxidant 2%, stearic acid 3%, superconducting graphite powder 37%; volume specific conductivity 12~15 ;

[0029] 2) The proportion of silver paste is as follows: 58% silicone rubber emulsion, 2% accelerator, 2% anti-aging agent, 3% stearic acid, 35% supe...

Embodiment approach 2

[0037] A kind of preparation method of the flexible transparent film that prints heat with silver paste, carbon paste, its steps are as follows: On the basis of embodiment 1, replace plastic film with TIE transparent plastic film and be polyamide ammonium film, the temperature of high temperature resistance It is 260°C. Polyamide ammonium film in 50㎝ 2 up to 250cm 2 The voltage of the large heating film is 110V~220V, and the heating line is a wide conductive film layer. The conductive heating film layer circuit is a circular "electric hob-type" wiring circuit. Such as figure 2 shown.

Abstract

The invention relates to the technical field of heating thin films and discloses a heating flexible transparent thin film printed with silver paste and carbon paste and a production method thereof. The thermostatic heating flexible transparent thin film comprises a TIE (titanium ethylene) transparent plastic thin film, the conductive silver paste and the carbon paste, the TIE transparent plastic thin film is provided with a conductive heating thin film layer line which is printed with the conductive silver paste and the carbon paste, and the conductive heating thin film layer line is zigzag. The heating flexible transparent thin film printed with the silver paste and the carbon paste is applicable to high-technology applications in the agricultural and the medical fields. The line design of the conductive heating thin film layer is even; after the conductive heating thin film layer is powered for heating, the heat density is large, and the heat is even; the base material thin film is transparent, flexible and foldable; and the thickness can be from 0.02 to 0.05. The printed conductive heating thin film layer cannot drop even being soaked for 24 hours and cannot be eroded in an alkaline soap solution; and no broken line exists after carrying out a plurality of rub tests are carried out, so that the heating flexible transparent thin film printed with the silver paste and the carbon paste has the advantages of low pressure, low temperature, low manufacture cost, usage safety and convenience and , reliable quality and the like.
