Problems solved by technology

However, with the increase of market inspection time, the shortcomings of resistance wire heaters such as large volume, short life, and low efficiency of electric heat utilization are gradually emerging. Many new-generation products are gradually eliminating resistance wire heating methods and replacing them with thick film circuit heating. element
[0003] Thick-film circuit heating elements have long been used only for high-end electronic equipment heating elements, such as small heating sheets or heating strips, due to high production costs and complicated manufacturing processes, and are rarely used in daily high-power household appliances. product

Abstract

The invention discloses a lead-free resistance paste as well as a manufacturing process and an application of the lead-free resistance paste. The resistance paste is prepared from the following components in percentage by mass: 25-60% of Ag / Pd alloy powder, 20-55% of inorganic function phase, 15-25% of organic carrier and 0.15-1.0% of organic additive. The resistance paste is an environment-friendly material; the resistance paste can be well matched with a microcrystalline glass plate and can be manufactured into a microcrystalline glass heating plate (disc); the microcrystalline glass heating plate (disc) is resistant to shock chilling and shock heating impact, does not fall and deform, and is low in power fluctuation, high in electrothermal utilization efficiency, long in service life, safe and reliable, small and beautiful, and thus is a good substitute for a traditional electric heating wire heating element.

Description

technical field [0001] The invention relates to a formulation of a lead-free resistance paste and a manufacturing process thereof. The resistance paste can be used to manufacture a thick-film circuit heating element, is suitable for a glass-ceramic heating plate, and is a good substitute for a traditional resistance wire heating element; The invention belongs to the field of electronic materials and composite materials. Background technique [0002] Traditional heating appliances such as electric rice cookers, electric pressure cookers, electric soup pots, electric kettles, electric heaters, etc. are mostly heated by resistance wires, which have the advantages of low price, simple manufacture and assembly, and are deeply loved by ordinary consumers. Since then, it has occupied a large market share.
