Abstract
The invention relates to an oxygen sensor, and in particular relates to a material of a chip oxygen sensor insulating layer. An organic matter for the chip oxygen sensor insulating layer is sepiolite, talcum, or mica. Slurry for the chip oxygen sensor insulating layer is prepared by adding the inorganic matter to an organic matter binding agent and an organic solvent, and implementing three-roller mixing and grinding, wherein the material of a chip oxygen sensor insulating layer comprises the following components in percentage by mass: 50-80% of the inorganic matter, 5-10% of the organic matter binding agent and 10-45% of the organic solvent. The inorganic matter, which uses sepiolite, talcum, or mica as an insulating layer of a chip oxygen sensor, can achieve purposes of high-temperature insulation and helping aluminum oxide sintering to form a dense layer.
Description
Technical field
The present invention relates to lambda sensor, particularly the material of chip oxygen sensor insulation course.
Background technology
In lambda sensor, between heating electrode and induction electrode, clip skim insulation course, the working temperature that this insulation course can prevent lambda sensor when more than 300 ℃, the voltage influence output voltage signal of heating electrode.In patent CN102455311, disclosed a kind of composition of insulation course, 75 parts, aluminium oxide, 3 parts of monox, 5 parts, magnesium oxide, 15 parts of terpinols, 2 parts of ethyl celluloses, in this composition, three kinds of oxides are all dystectic oxides, during sintering cannot with zirconia matrix generation co-sintering, therefore after burning, still there is very macropore, reduced the thermal shock resistance of lambda sensor; The patent also having has added low-temperature glaze and aluminium oxide in insulation course, low-temperature glaze can reduce the sintering temperature of aluminium oxide, but also can bring a series of problem, as low-temperature glaze has electron conduction when the working temperature of lambda sensor, so insulation course cannot insulate, output voltage is greater than 1.0V; In other patent, disclosed BaAl

The present inventor analyzes some mineral and can be used as insulation course use, can meet high-temperature insulation and help alumina sintering to form the object of tight zone.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of chip oxygen sensor insulation course inorganics, and a kind of chip oxygen sensor insulation course slurry is also provided.
Technical matters to be solved by this invention is achieved by the following technical programs:
A kind of chip oxygen sensor insulation course inorganics is sepiolite or talcum or mica.Sepiolite has Mg

A chip oxygen sensor insulation course slurry, is mixed and finely ground and makes for above-mentioned inorganics adds organic matter binding agent and organic solvent to carry out three rollers.
Further, each constituent mass number percent is inorganics 50-80%, organic matter binding agent 5-10%, organic solvent 10-45%.
The present invention has following beneficial effect:
The present invention uses sepiolite, talcum or three kinds of mineral of mica to use as the insulation course of chip oxygen sensor, can meet high-temperature insulation and help alumina sintering to form the object of tight zone.
