Heating element and preparation method thereof
The invention belongs to the technical field of novel tobaccos, and particularly relates to a heating element and a preparation method thereof. The heating element comprises a heating body and an insulating filler arranged in the heating body. Wherein the heating body is made of metal silicide and non-conductive ceramic, and the mass ratio of the metal silicide to the non-conductive ceramic is (0.1: 1)-(5: 1). The problem that the heating performance fluctuation difference of the heating assembly in the production process is large is solved, and the rate of finished products is greatly increased; and meanwhile, the heating element prepared by the method disclosed by the invention has better bending strength and fracture toughness, so that the service life of the heating element is prolonged.
本发明属于新型烟草技术领域，具体涉及一种发热元件及其制备方法。该发热元件包括发热体和设置在所述发热体内部的绝缘填充物；其中，所述发热体由金属硅化物及非导电陶瓷制成，所述金属硅化物与非导电陶瓷的质量之比为:0.1:1~5:1。本发明解决了发热组件在生产过程中发热性能波动差异大的问题，大幅提高成品率；同时通过本发明的方法制备的发热元件具有较优的弯曲强度和断裂韧性，从而提高发热元件的使用寿命。
