Embodiment 1

[0030] refer to Figure 1 to Figure 2 , a flame-retardant polypropylene film sealing bag for a graphene electric heating film, comprising a flame-retardant polypropylene film 1, a graphene electric heating film 2 and a flame-retardant polypropylene film 3 laminated sequentially from top to bottom, the graphene electric heating One short side of the membrane 2 is connected with a plug-in cable 4 for power supply. When sealing, a piece of special glue 5 is wrapped around the plug-in cable, and then it is initially bonded with the upper and lower layers of flame-retardant polypropylene film. The upper and lower layers of the ultrasonic plastic welding machine use a special mold. There is a groove 6 on the mold, and the groove 6 The position is aligned with the cable wrapped with glue. During the ultrasonic welding process, the special glue is melted to make the upper and lower flame-retardant polypropylene films and the plug-in cables tightly bonded together, and the flame-retard...

Abstract

The invention relates to a flame-retardant polypropylene film sealing bag used for a graphene electrical heating film. The flame-retardant polypropylene film sealing bag comprises the graphene electrical heating film and upper and lower flame-retardant polypropylene films, wherein the upper and lower flame-retardant polypropylene films sleeve the graphene electrical heating film. The short edge onone side of the graphene electrical heating film is connected with an insertion cable and used for being connected with a power supply. When the graphene electrical heating film is encapsulated withthe flame-retardant polypropylene films, the problems in the prior art are solved that a material for encapsulating the electrical heating film is poor in heat stability, high in smoke density duringcombustion, poor in shock resistance and environmentally unfriendly.

Description

technical field [0001] The invention relates to the technical field of electric heating films, in particular to a flame-retardant polypropylene film sealing bag for graphene electric heating films. Background technique [0002] Low-temperature electric heating film is a kind of polyester film that can generate heat after being energized. It is generally made of conductive special ink and metal current-carrying strips, and the electric heating film is covered with a polyvinyl chloride protective film for heating systems. When the electrothermal film is in working state, it sends heat into the space in the form of radiation, heating the human body and objects, and its comprehensive effect is better than the traditional convection heating method. [0003] In the traditional electric heating film, the electric heating film is externally encapsulated with polyvinyl chloride film. Under heated conditions, polyvinyl chloride is prone to self-catalyzed dehydrochlorination reaction, ...
