Heating non-combustible smoking set metal substrate rare earth thick film heating sheet making method

Abstract

The invention discloses a heating non-combustible smoking set metal substrate rare earth thick film heating sheet making method. The method comprises the following steps of S1, substrate stamping, S2, surface treatment, S3, insulating layer making, S4, heating thick film slurry printing: screen printing rare earth thick film slurry is used outside the insulating layer, the printing thickness is controlled to be 0.05 to 0.1 mm, and then, heating and curing are carried out to form a rare earth thick film electrode, S5, connection circuit printing and S6, protection layer printing. The above making method has a simple processing step, the operation is easy, the above technical scheme overcomes the defects of high production cost, high risk coefficient and easy explosion of the conventional MCH ceramic heating body in the technical field of smoking sets, the rare earth thick film material is applied to the smoking set field to make a heating sheet, the production cost is greatly reduced, damage is not easy, the safety coefficient is high, wide promotion is easy, and the prepared product is high in conversion efficiency, good in insulation, quick in heating speed and good in use effects.

Description

technical field [0001] The invention relates to the technical field of smoking utensils, in particular to a method for manufacturing a heating sheet for a metal base material of a heating-not-burning smoking utensil. Background technique [0002] Cigarettes are a kind of tobacco products. Many people like to smoke cigarettes to relieve stress and refresh themselves. Regular smoking of cigarettes will lead to addiction. Tobacco will produce tar, nicotine, carbon monoxide, etc. when burned. Harmful, and the harm of second-hand smoke is greater than that of first-hand smoke, so many public places will have smoking ban measures, and when smoking tobacco will produce open flames, which can easily cause fires, so people have created a heat-not-burn smoke, heat-not-burn smoke It can meet the needs of smokers, and can reduce the content of tar and nicotine, so it is sought after by smokers. [0003] However, most of the existing heat-not-burn cigarettes are heated by resistance hea...

Problems solved by technology

[0008] However, the MCH co-fired ceramic heating substrate disclosed above and its preparation method need to be sintered under the protection of a hydrogen atmosphere at 1600°C, which not only has high production costs, but also has a high risk factor and is prone to explosion, which is not conducive to widespread promotion.
