Embodiment 1

[0037] A device for preparing a coating layer of an electric heating network, comprising a dip coating area, a hot air drying area, and a heat curing area arranged in sequence. When in use, inject the slurry of the coating layer material into the dip coating area, and then send the base material to be coated to the dip coating area to be immersed in the slurry of the coating layer material, so that the slurry of the coating layer material wets the substrate The surface of the material, and then immediately sent to the hot air drying area, under the action of hot air, the coating material slurry coated on the surface of the base material is gradually dried, and then sent to the heat curing area, under the action of hot air at a higher temperature to achieve Thermal curing of coating layers. The equipment adopts simple structure and convenient operation, and the prepared coating layer has uniform structure and stable performance.

[0038]As an option, in the above-mentioned equ...

Embodiment 2

[0050] like figure 1 As shown, a kind of equipment for preparing the coating layer of the electric heating network, the whole equipment is in the shape of a tower, including the tower body and the dip coating area, the hot air drying area and the heat curing area distributed in the tower body from bottom to top in sequence, the hot air The drying area and the heat curing area are respectively connected with the high temperature furnace and the fan through the air supply pipe, and the high temperature air generated in the high temperature furnace is sent to the hot air drying area and the heat curing area respectively through the fan, and the hot air drying area and the heat curing area After the temperature is lowered, the air is recycled or emptied. There are multiple guide rollers in the tower body, and a traction mechanism is provided outside the tower body. The traction mechanism is used to pull the product to drive the base material to be coated in the equipment The dippi...

Embodiment 3

[0056] A kind of equipment for preparing the coating layer of electric heating network, the difference between the equipment and the equipment described in Example 2 is only that: the dip coating area in the tower body includes two first dip coating tanks and two a second dipping tank. When in use, the substrate first enters the first first dip-coating tank for dip-coating, then passes through the hot-air drying zone and heat-curing zone upwards for drying and thermal curing, and then enters the second first dip-coating tank downwards and then goes up sequentially. Pass through the hot air drying area and heat curing area for drying and heat curing, then go down to the first and second dip coating tanks, then go up and pass through the hot air drying area and heat curing area in turn for drying and heat curing, and then go down to the second Two dip coating tanks, and then pass through the hot air drying zone and heat curing zone upwards for drying and thermal curing (this pro...

Abstract

The invention discloses a preparation method and equipment of a coating layer of an electric heating net. The preparation method comprises the following steps: dipping a base material to be coated in a sizing agent of a coating layer material; carrying out hot air drying; carrying out hot solidification under hot air; the preparation method is simple to operate, the product is stable in performance, the quality is easy to control and the service life is long. The equipment comprises a dip-coating groove, a hot air drying area and a hot solidification area. The equipment is simple in structure and convenient to use and is capable of carrying out large-scale continuous production. By using the equipment, not only a conductive layer, but also an insulating layer can be prepared, and the prepared coating layer is uniform in structure and stable in performance.

Description

technical field [0001] The invention belongs to the field of preparation of electric heating nets, and in particular relates to a preparation method and equipment for coating layers of electric heating nets. [0002] technical background [0003] At present, the existing electric heating grid is usually coated with conductive silicone rubber on the reticulated glass fiber fabric to form a conductive mesh structure, and it is usually necessary to coat an insulating layer on the periphery of the conductive silicone rubber layer. Due to its good high and low temperature resistance, silicone rubber, carbon particles and glass fibers are polymerized into a mesh heating element, which is one of the traditional conductive heating element materials, and silicone rubber is also an option for preparing insulating layers Material. Most of the equipment for preparing the coating layer of the electric heating net in the prior art is relatively complicated, and the manufacturing process i...
