It is mainly made of materials such as iron-chromium-aluminum alloy and nickel-chromium alloy, and has good oxidation resistance and high-temperature stability. However, the existing nickel-chromium electrothermal alloy wires have certain drawbacks. Firstly, their surface wear and compression resistance are poor, and during use, they may be punctured by sharp objects, resulting in a certain degree of damage to themselves, affecting their heating effect. In severe cases, it may lead to spontaneous combustion. Content of the Utility Model

[0005] As a further solution of the utility model: The heat conduction layer is wrapped on the alloy wire body, the number of the heat conduction blocks is ten, and the ten heat conduction blocks are evenly distributed on the heat conduction layer. The heat conduction blocks are fixedly connected to the heat conduction layer, and one end of the heat conduction block is lapped on the heat-resistant layer.

[0006] As a further solution of the utility model: The filling layer is installed between the heat conduction layer and the heat-resistant layer, and both sides of the filling layer are lapped on the heat conduction blocks. The anti-puncture layer is an aramid layer, the corrosion-resistant layer is an anti-corrosion rubber layer, and the wear-resistant columns are fixedly connected to the corrosion-resistant layer.

[0008] The electrothermal alloy wire for an electric blanket, by setting a heat-conducting layer, heat-conducting blocks, a heat-resistant layer, an insulating layer, a puncture-proof layer, a corrosion-resistant layer, and wear-resistant columns. When the alloy wire body generates heat during operation, the heat-conducting layer, through the cooperation of the heat-conducting blocks, transfers the heat to the heat-resistant layer, achieving good heat transfer and greatly improving the heat dissipation effect of the electrothermal alloy wire. And through the cooperation of the insulating layer, the occurrence of electric leakage of the electrothermal alloy wire is avoided. Moreover, multiple wear-resistant columns are fixedly connected to the corrosion-resistant layer, thus greatly reducing the wear rate of the corrosion-resistant layer. And the corrosion-resistant layer is an anti-corrosion rubber layer, which can effectively resist the erosion of corrosive media such as acids, alkalis, and salts, and has a certain compressive performance, protecting the alloy wire body from corrosion and wear. And the puncture-proof layer is an aramid layer.
