Embodiment 1

[0029] A production method of an electric heating film for an electric heating floor:

[0030] (1) Spraying: Use an electrostatic spraying machine to spray graphite powder coating on the surface of the flame-retardant paper. The thickness of the flame-retardant paper is 0.5mm, 110g / square. Under the action of static electricity, the powder will be evenly adsorbed on the surface of the workpiece. After warm baking and solidification, the powder layer is leveled and becomes a uniform film layer, and the thickness of the film layer is controlled at 0.1mm; the amount of powder sprayed is generally controlled within the range of 70g / min, and the resistivity of the film-coated paper after spraying reaches 6Ω / cm;

[0031] During the test, the fixed width is 1 cm, and the length is selected from 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 cm paper blocks. After measurement, the resistance value per square centimeter is calculated, and the average value of 10 blocks is taken as a test whether it is ...

Abstract

The invention discloses a production method of an electric heating film of an electric heating floor. The method comprises the first step of spraying, wherein powder spraying equipment is used for spraying graphite powder coatings on the obverse surface and reverse surface of flame retarding paper, powder will be evenly adsorbed on the surface of a workpiece under electrostatic interaction, and a powder layer levels out to become an even film layer after heating, baking and curing are performed; the second step of smashing, wherein a paper pulverizer is used for carrying out micro block (paper scrap) cutting on the paper with the coatings; the third step of even distribution, wherein waste paper scraps are evenly distributed on a general polyester film of the electric heating floor, and the polyester film is fully covered with the paper scraps under control of slab slight shock equipment; the fourth step of junction, wherein pure copper strips are arranged at the two ends of the polyester film according to the manufacturing dimension of the product and serve as two poles of power source input; the fifth step of compounding, wherein another polyester film of the same size covers the product, the product is sealed in a high-temperature press fit mode, and water resistance and insulation are achieved.

Description

technical field [0001] The invention relates to a production method of an electric heating film, in particular to a production method of an electric heating film for an electric heating floor. Background technique [0002] Electrothermal film floor technology is a low-carbon heating high-tech product used in the field of surface heating, which is different from point heating systems represented by radiators, air conditioners, and radiators and linear heating systems represented by heating cables. The electric heating film is a translucent polyester film that can generate heat after being energized. When working, the electric heating film is used as a heating element, and the heat is sent into the space in the form of radiation, so that the human body and objects are warmed first, and its comprehensive effect is better than the traditional one. Convection heating. This unique heating method makes people feel that the indoor temperature is uniform, fresh, comfortable and quie...
