Abstract

The invention discloses a mica heating film and a manufacturing method thereof. The mica heating film comprises an upper-layer mica plate, a lower-layer mica plate, a snakelike resistance wire and twometal terminals, the snakelike resistance wire is in a sheet shape and is horizontally arranged, and the upper-layer mica plate and the lower-layer mica plate are both parallel to the snakelike resistance wire; and the two metal terminals are arranged on the upper side and the lower side of the serpentine resistance wire respectively, the upper-layer mica plate and the lower-layer mica plate arebonded together to fix the serpentine resistance wire between the upper-layer mica plate and the lower-layer mica plate, and one ends of the two metal terminals are connected with the two ends of theserpentine resistance wire respectively. The other end of each mica plate extends out of the two mica plates. According to the mica heating film and the manufacturing method thereof provided by the invention, the manufacturing process is simpler, and the labor cost is reduced.

Description

Technical field[0001]The invention relates to the field of a mica heating film and a manufacturing method thereof. More specifically, the present invention relates to a mica heating film and a manufacturing method thereof.Background technique[0002]At present, a large number of toasters (ie bread toasters) are used in the market. Its heating and flame retardant materials are mainly mica with mica board as the skeleton, and the heating is made by winding nickel-chromium or iron-chromium alloy resistance wire on the mica board. The electric current passes through the resistance wire to convert electrical energy into heat to bake bread. At the same time, the mica board in the heating piece can play a role of support and insulation. Mica board is a kind of high-quality insulation and high temperature resistant material. It has the advantages of non-toxic, odorless, high temperature resistance, high pressure resistance, aging resistance, corrosion resistance, stable electrical performance...
