Embodiment 1

[0034] S1. First select a plurality of carbon fiber bundles, and then cross-weave the plurality of carbon fiber bundles into a strip-shaped conductive carbon fiber cloth 1. The formation of multiple fiber bundles is formed by discontinuous fibers that have undergone graphitization high-temperature treatment. The strip-shaped conductive carbon fiber cloth 1 is Graphitized carbon fiber cloth;

[0035] S2. First, the first protective layer 6 and the strip-shaped conductive carbon fiber cloth 1 are bonded together with thermoplastic polyurethane elastomer rubber, and they need to be smooth, and then use a brushing tool to evenly coat the conductive silver paste or missile carbon paste with the strip shape. The position of 13 centimeters of conductive carbon fiber cloth 1 both ends, the first protective layer 6 is flannelette, and bonding agent is the conductive silver paste that contains 80% weight;

[0041] S1. First select a plurality of carbon fiber bundles, and then cross-weave the plurality of carbon fiber bundles into a strip-shaped conductive carbon fiber cloth 1. The formation of multiple fiber bundles is formed by discontinuous fibers that have undergone graphitization high-temperature treatment. The strip-shaped conductive carbon fiber cloth 1 is Polyacrylonitrile carbon fiber cloth;

[0042] S2. First, the first protective layer 6 and the strip-shaped conductive carbon fiber cloth 1 are bonded together with thermoplastic polyurethane elastomer rubber, and they need to be smooth, and then use a brushing tool to evenly coat the conductive silver paste or missile carbon paste with the strip shape. Conductive carbon fiber cloth 1 both ends 10 centimeters position, first protection layer 6 is flannelette, and bonding agent is carbon content in 88% conductive carbon paste;

Abstract

The invention discloses a preparation method of a carbon fiber cloth heating sheet. The preparation method comprises the following steps: S1, selecting a plurality of carbon fiber bundles to prepare ashaped conductive carbon fiber cloth; S2, bonding a first protective layer with the shaped conductive carbon fiber cloth by thermoplastic polyurethane elastomer rubber; S3, then placing the coated heating sheet in an oven; S4, respectively and correspondingly welding a first lead and a second lead on a first end point and a second end point; S5, separately sewing a temperature sensor and a temperature control switch on the shaped conductive carbon fiber cloth; and S6, finally bonding a second protective layer with the previously prepared heating product by thermoplastic polyurethane elastomerrubber. Through the preparation method of the carbon fiber cloth heating sheet, the prepared carbon fiber cloth heating sheet is light, thin and soft, is easily bendable, is uniform in heating, and can be widely applied to the fields of medical treatment, textile and sports equipment.

Description

technical field [0001] The invention relates to the technical fields of medical treatment, textile and sports equipment, in particular to a method for preparing a carbon fiber cloth heating sheet. Background technique [0002] The heating sheet is a sheet-shaped electric heating element. The heating sheet uses the good insulation performance and high temperature resistance of the mica board (mica sheet). It uses the mica board (sheet) as the skeleton and insulating layer, supplemented by galvanized sheet Or stainless steel plate for support and protection, can be made into plate-shaped, sheet-shaped, cylindrical, conical, cylindrical, circular and other sheet-shaped heating devices, the normal surface load is 2.5-3W, and the temperature can withstand 500 ° C. Heater is a sheet-shaped electrical component that converts electrical energy into heat energy. Because of its cheap price, convenient use, easy installation, and no pollution, it is widely used in various heating occas...
