Abstract

The invention belongs to the field of new materials, and provides an inorganic resistor thick film and a preparing method and application of the inorganic resistor thick film. The inorganic resistor thick film comprises graphite powder, bismuth oxide, boric oxide, silica, antimonous oxide, zinc oxide, strontium carbonate and the like. According to the inorganic resistor thick film, the bismuth oxide serves as the framework material, the boric oxide, silica, the zinc oxide, the strontium carbonate and the like are used in cooperation with the bismuth oxide, the performance of the inorganic resistor thick film is achieved, and meanwhile compared with existing lead oxide, the inorganic resistor thick film has the advantages that the lead content is zero, and people are prevented from getting lead poisoning in the process of producing and using the inorganic resistor thick film and the environment is prevented from being polluted. The using temperature of the inorganic resistor thick film is greatly increased due to the bismuth oxide, and the application range of the inorganic resistor thick film is enlarged. The preparing method of the inorganic resistor thick film is easy to operate, low in cost and very suitable for industrial production.

Description

technical field

[0001] The invention belongs to the field of new materials, and in particular relates to an inorganic resistance thick film, its preparation method and application. Background technique

[0002] Inorganic resistor thick film has an important application range, and the electrical performance, stability, environmental protection performance and service life of inorganic resistor thick film are the decisive factors of inorganic resistor thick film. At present, the inorganic resistor thick film on the market uses lead oxide as the main component. Lead oxide is indispensable as the skeleton material of the inorganic resistor thick film. Without lead oxide, the film cannot be formed. The content of lead oxide in the inorganic resistor thick film reaches 50%. above. The preparation of this kind of inorganic resistance thick film with high lead content will produce waste water, waste gas and other pollutants. What's more serious is that because the application fiel...
