Problems solved by technology

[0003] However, in the production process of the cermet heating element, the resistance and TCR (resistance resistance) of the cermet heating element will be affected due to the ratio formula of the metal paste, modulation speed, storage time, printing environment, printing conditions and firing environment factors. temperature coefficient) electrical index, thereby affecting the heating performance, so the heating element of this type of low-temperature non-burning new cigarette is prone to fluctuations in heating performance during industrial production, resulting in low yield and increased production costs
At the same time, the heating element is easily damaged by pollution and has a short service life

Abstract

The invention discloses a heating assembly for a low-temperature tobacco product and a preparation method of the heating assembly, the heating assembly comprises a heating body and a protective body used for protecting the heating body, and the protective body wraps the heating body and is used for transferring heat generated by the heating body to the low-temperature tobacco product. The preparation method of the heating assembly comprises the following steps: firstly, obtaining the heating body; embedding the heating body into the protective body which is heated to a molten state, and cooling to form the heating assembly; or obtaining the heating body firstly; and embedding the heating body into the protective body powder, and performing pressure sintering to form the heating assembly. The problem of large heating performance fluctuation difference of the heating assembly in the production process can be solved, the rate of finished products is greatly increased, meanwhile, the heating body can be effectively protected against pollution and damage, and the service life of the heating assembly is prolonged.

Description

technical field [0001] The invention belongs to the technical field of new cigarettes, and in particular relates to a heating component for low-temperature tobacco products and a preparation method thereof. Background technique [0002] Low-temperature non-burning new cigarettes generally use MCH ceramic heating elements (ceramic heating elements) as the main electric heating method. The cermet heating element is a high-temperature co-fired multi-layer metal-ceramic composite material. The heat-generating metal paste is prepared with metal powder such as tungsten and manganese and an organic solvent, and then printed on the alumina ceramic as an insulating medium by a printing machine. On the green body, another alumina ceramic green body is superimposed on it, and it is integrated by high-temperature co-firing in a reducing atmosphere. [0003] However, in the production process of the cermet heating element, the resistance and TCR (resistance resistance) of the cermet hea...
