Resinous Porous Article and Method for Production Thereof |
摘要 |
The present invention provides a resinous porous article having a high interconnected hole porosity and capable of retaining a large amount of a lubricating oil and does not rust iron and steel, even though an unextracted portion of a pore-forming substance bleeds out when the resinous porous article is used as parts which contact a metal portion or the like and a method of producing the resinous porous article. The resinous porous article is formed by a producing method of molding a resin containing the pore-forming substance into a molding, and extracting the pore-forming substance from the molding with a solvent which does not dissolve the resin therein. The resinous porous article has an interconnected hole porosity not less than 30%. The pore-forming substance consists of an alkali compound.
