Problems solved by technology

[0005] The existing graphene electric heating film and the heat sink are usually bonded with a layer of adhesive layer. The adhesive layer has poor heat resistance, and it will age after long-term use, and there are hidden dangers of bubbling and local delamination. , and the adhesive layer is almost polymer-based, which does not have thermal conductivity, which affects the heat conduction between the graphene electrothermal film and the heat sink, and reduces the heating efficiency

[0072] The preparation method is as follows:

[0073] (1) Preparation of graphene electrothermal film:

[0074] According to the general method of public information, first mix 90 parts of polymer film-forming resin vinyl resin, 10 parts of diluent absolute ethanol, 10 parts of graphene, and additive dodecylbenzenesulfonic acid sodium salt 0.2 parts, and mix evenly to obtain graphite Graphene resin mixture (graphene needs to be dispersed before use, and the dispersion method is ultrasonic dispersion in absolute ethanol for 30 minutes), and then the graphene conductive material is formed on the polyimide carrier by printing or spraying or coating. layer, and then dried to obtain a graphene conductive layer, electrodes are placed on the edge of the graphene layer, and a layer of polyimide insulating protective film with adhesive is attached on the graphene layer to make a graphene electric heating film .

Abstract

The invention relates to an insulating heat-conducting adhesive film for a heating device and the heating device. The insulating heat-conducting adhesive film is prepared from the following componentsin percentage by mass: 10%-70% of epoxy resin, 4.5%-50% of thermoplastic resin and / or synthetic rubber, 20%-80% of heat conducting filler and 1%-10% of a curing agent. The insulating heat-conductingadhesive film has excellent bonding, insulation, heat conduction, flame retardance and weather resistance, and the heating device made of the insulating heat-conducting adhesive film has the advantages of low energy consumption, high heating speed, high safety, long service life and the like.

Description

technical field [0001] The invention relates to an insulating and heat-conducting adhesive film used for heating devices and a heating device made thereof. Background technique [0002] The main fuel used in traditional heating methods is coal. However, with the use of coal, the problems of smog, air pollution, and environmental pollution are becoming more and more serious. The "coal-free" rectification is urgent. It is the general trend to completely replace coal-fired boilers with energy-saving and environmentally friendly electric heating. . As we all know, electric heating mainly uses electric energy. In today's developed circuits, the equipment is very convenient to use. The most important thing is flexible control, which can be used according to your own needs, controlled by room, switched on and off at any time, and is not affected by central heating. Time constraints, and will not affect your own heating due to other users' arrears of heating bills. [0003] Graphe...
