Embodiment

[0067] The present invention is explained in more detail with reference to the following Examples and Comparative Examples, but these Examples are exemplary embodiments and the present invention should not be construed as being limited thereto.

[0068] By mixing the first solid lubricant, the second solid lubricant, lubricant base oil, lubricant base oil plus thickener, organic resin, copper oxide, thallium oxide, iridium oxide, osmium oxide according to the mixing ratio shown in Table 1 , rhodium oxide and ruthenium oxide to prepare Test Examples 1 to 33. The preparation method of the test example is not particularly limited. The test example can usually be obtained by mixing and stirring the first solid lubricant, the second solid lubricant, lubricant base oil, lubricant base oil plus thickener, organic resin, copper oxide, thallium oxide, iridium oxide, osmium oxide, oxide Rhodium and ruthenium oxide, if necessary, using a three-roll mill or homogenizer for dispersion tre...

Abstract

An anti-seizing agent including: a first solid lubricant containing at least one of bismuth and a bismuth compound; and a second solid lubricant containing at least one of graphite, molybdenum disulfide and boron nitride. The anti-seizing agent satisfies the relationships 20 weight %<=a<=90 weight % and 10 weight %<=d<=80 weight %, in which a sum of the contents of the first solid lubricant and the second solid lubricant in the anti-seizing agent is taken as 100 weight %, and a represents a content of the first solid lubricant and d represents a content of the second solid lubricant.

Description

technical field [0001] The invention relates to a heat-resistant adhesive. In particular, the present invention relates to an anti-seizing agent for preventing partial seizing that may be exposed to a high temperature of 500° C. or higher, a sensor employing the anti-seizing agent, and a component including the sensor. Background technique [0002] An anti-seal compound is often applied to the threaded portion of a metal part to prevent heat-staining before the part is used for fabrication. The metal part includes a metal casing of a gas sensor and a metal casing of a temperature sensor, wherein the gas sensor is assembled to an exhaust pipe of an internal combustion engine, etc. for detecting a specific gas component in the gas to be measured, and the temperature sensor is assembled to an exhaust pipe Gas pipes and the like are used to detect the temperature of the gas to be measured. Examples of the anti-seal agent include a paste anti-seal agent comprising a lubricant b...
