Abstract
Official abstract text for this publication.
Disclosed is a surface-treating agent for oil seal lip portion, comprising a lubricant filler and an adduct compound consisting of an adduct of toluene diisocyanate and trimethylolpropane, the surface-treating agent being applied to the surface of vulcanized rubber forming a lip portion of an oil seal comprising the lip portion and a metal ring. The application of the surface-treating agent of the present invention to the sliding surface of a seal lip portion of an oil seal effectively lengthens the service life of the oil seal, when used in a sliding part or a moving part, and leads to energy saving of equipment that uses the oil seal.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of surface-treating an oil seal lip portion of an oil seal comprising the lip portion and a metal ring, the method comprising providing a surface treating agent comprising a lubricant filler and an adduct compound consisting of an adduct of toluene diisocyanate and trimethylolpropane; and applying the surface-treating agent a surface of vulcanized fluororubber or vulcanized acrylic rubber forming a lip portion of an oil seal comprising the lip portion and a metal ring. 2. The method according to claim 1 , wherein the lubricant filler is a fluororesin powder, graphite, or molybdenum disulfide. 3. An oil seal comprising a lip portion made of vulcanized rubber and a metal ring, the surface of the lip portion being subjected to surface treatment method according to claim 1 . 4. An oil seal comprising a lip portion made of vulcanized rubber, the surface of the lip portion being subjected to the surface treatment method according to claim 2 .
