Description
Technical Field
The utility model belongs to the technical field of antistatic films, and particularly relates to an antistatic heating film.
Background
Release paper, also known as silicone paper, release paper, mainly plays a role of isolating objects with viscosity, such as adhesive tapes. The release paper is mainly used as a carrier of an adhesive tape or an adhesive product, and generally needs to be peeled and discarded when in use, so that the application range is wider.
A heating film is a component for heating, which is a design of a pure resistance circuit, and generates heat by a resistance as a stable heat source through input voltage, and is conducted to a component to be heated through an insulating heat conducting material. Heating films are involved in many fields, such as the communication industry (outdoor/indoor cabinets), the new energy industry (automobiles, photovoltaics), the medical equipment field, etc. In order to make the heating film better applicable to various scenes, a double-sided adhesive tape is usually attached to the outside of the heating film, so that the heating film can be attached to any component to be heated. In order to facilitate film tearing and attachment, a layer of release paper is designed on the surface of the double-sided adhesive tape. However, the heating film can generate static electricity in the process of tearing off the release paper for adhesion, which is not only inconvenient for adhesion, but also causes dust adhesion phenomenon; and a large amount of static electricity may risk damaging the heated component. At present, the existing anti-static ionization paper cannot be well applied to a heating film, and a large amount of charges still remain on the double-sided adhesive tape during use and are finally conducted to a heated component, so that the heated component is influenced.
Therefore, it is desirable to provide a heating film that can reduce the generation of electrostatic charges and the residual of the electrostatic charges during the film tearing (release paper) process, and avoid the damage of the heated member by the electrostatic charges.
