An aqueous surface-treating agent which comprises an aqueous emulsion of a silicone oil, an aqueous emulsion of a polyurethane resin, and a silane compound represented by the general formula (A), (B) CH2=C(CH3)COO(CH2)3Si(OR1)nR2m, (C) CH2=CHCOO(CH2)3Si(OR1)nR2m, (D) H2N(CH2)3Si(OR1)nR2m, or (E) H2NC2H4NH(CH2)3Si(OR1)nR2m (wherein R1 and R2 each is C1-4 alkyl; and n and m satisfy 1≤n≤3 and m=3-n) and/or a partial hydrolyzate of the silane compound, wherein the polyurethane resin is used in an amount of 100 parts by weight or larger on a solid basis per 100 parts by weight of the nonvolatile matter of the silicone oil. This aqueous surface-treating agent prevents a sealing material made of rubber, such as an O-ring, from sticking to another sealing material or to a metal, resin, etc. It further attains a reduction in friction in the sliding of a sealing member made of rubber or resin.

Abstract

A grease composition comprising a mixture of thickening-agent-loaded nonfluorinated base oil and thickening-agent-loaded fluorinated base oil being incompatible with each other, wherein one of the base oils is uniformly dispersed in the other base oil in particulate form creating a morphological structure. This grease composition is produced by, for example, milling a mixture of thickening-agent-loaded nonfluorinated base oil and thickening-agent-loaded fluorinated base oil being incompatible with each other by means of a triple roll mill at least twice. By virtue of the formation of a microscopic dispersion state such that one of nonfluorinated base oil and fluorinated base oil being incompatible with each other is uniformly dispersed in the other base oil in particulate form creating a morphological structure, there can be exerted the effects inclusive of (1) less oil separation (separated oil level) at high temperature, (2) excellence in shear stability, (3) low and stable friction coefficient and (4) less abrasion.

Abstract

A lubricating oil composition for use in oil-impregnated bearings to be used in combination with a resinous member having C=C bonds or C=O groups in the molecule. It comprises a base oil comprising a synthetic hydrocarbon oil as the main ingredient and an ester base oil, the amount of the ester base oil being 0.1-30 wt.% based on the whole composition, and contains neither a zinc dialkyl dithiophosphate nor a molybdenum dialkyldithiocarbamate. This lubricating oil composition is one which contains a synthetic hydrocarbon oil as a major ingredient and has satisfactory resistance to resins. The composition is effective in minimizing the amountof a wearing inhibitor or extreme-pressure additive to be incorporated therein while retaining intact satisfactory lubricity, which is required of oils for sintered oil-impregnated bearings. Thus, it becomes possible to minimize the influence of these on various metals of sintered materials.

Abstract

Disclosed is a lubricant composition for oil retaining bearings which is obtained by adding and mixing a fluorine-containing di- or mono-amide compound into a base oil which is composed of at least one oil selected from perfluoropolyether oils represented by the following general formula: RfO(CF2CF2O)m(CF2O)nRf (wherein Rf represents a perfluoroalkyl group having 1-5 carbon atoms, m + n = 3-200, and m:n = 10-90:90-10), perfluoropolyether oils represented by the following general formula: RfO[CF(CF3)CF2O]p(CF2CF2O)q(CF2O)rRf (wherein Rf represents a perfluoroalkyl group having 1-5 carbon atoms, p + q + r = 3-200 and q and r may respectively represent 0, and (q + r)/p = 0-2), and polyfluoropolyether oils represented by the following general formula: F(CF2CF2CF2O)sC2F5 (wherein s = 2-100). This lubricant composition for oil retaining bearings is further improved in lubricating characteristics of perfluoropolyether oils, particularly in wear resistance and friction coefficient characteristics.

Abstract

A grease composition which comprises (A) a perfluoropolyether base oil, (B) a thickening agent, and (C) barium sulfate and/or antimony oxide, the amounts of the ingredients (B) and (C) incorporated being 0.1-50 wt.% and 1-25 wt.%, respectively. Due to the addition of the ingredient (C), which is at least one of barium sulfate and antimony oxide each having an average primary-particle diameter of 0.1-20 쎽m, the grease composition can produce the excellent effect of improving wearing resistance, frictional properties, load resistance, high-temperature durability, and unsusceptibility to corrosion while retaining the intact heat resistance.
