The invention relates to a lubricant composition based on modified, natural and renewable raw materials, the viscosity of which can be adjusted according to the application. The invention relates more particularly to biodegradable lubricant compositions.
摘要:
The invention relates to lubricating grease compositions having a base oil mixture based on oils having viscosities (ISO VG 2 to ISO VG 1500) that are standard for industrial lubricants, an ionic liquid, a thickening agent, e.g., based on a polyurea compound and conventional additives that can be used at current service temperatures that are higher than 120° C. to 260° C., in particular at a service temperature in the region of high service temperatures that are higher than 180° C. to 260° C. and also at low temperatures as low as −60° C. The invention also relates to a method for producing said type of lubricating grease compositions.
摘要:
The rolling bearing of the invention to be incorporated in the compressor for fuel cell system comprises a fluorine-based grease containing a fluororesin and a fluorine-based oil, a urea grease containing a urea compound and a synthetic oil or a lithium complex grease containing a lithium complex and a synthetic oil encapsulated therein. In this arrangement, the grease deterioration of the rolling bearing incorporated in the compressor for force-feeding various fluids between machines can be prevented, making it possible to provide a fuel cell system which can maintain stable operation over an extended period of time.

A silicone composition containing: (A) 100 parts by weight of organopolysiloxane; 0.1 to 50 parts by weight of thickening agent (C) 0.01 to 20 parts by weight of fluorine-containing surfactant; and (D) 0.1 to 20 parts by weight of volatile water-soluble solvent.
摘要:
Coating formulations which behave as elastic solids having reversible stress-induced fluidity are prepared by creating a fluid having distributed therein effective amounts of ionic charge sites and countercharge sites. For instance, elastic solids having reversible stress-induced fluidity are prepared by combining liquid formulations with a dispersion of a small, but effective, amount of at least one crystalline mixed metal hydroxide conforming substantially to the formulaLi.sub.m D.sub.d T(OH).sub.(m+2d+3+n.multidot.a) (A.sup.n).sub.a .multidot.xH.sub.2 Owhere m is zero to one, D is a divalent metal, d is from zero to 4, T is a trivalent metal, A represents at least one anion or negative-valence radical of valence n and a is the amount of A, where n is 1 or more, (m+2d+3+n.multidot.a) is equal to or greater than 3, (m+d) is greater than zero, and xH.sub.2 O represents excess waters of hydration, if any. The coating formulations include, for example, paints, resin coatings, adhesives, de-icers, curable coatings, dryable coatings, and hardenable coatings.
摘要:
Silicone grease compositions are prepared by blending a thickening agent with a liquified crosslinked organosiloxane gel produced using a platinum-catalyzed hydrosilylation reaction. The gel is liquified by application of a shearing force to the crosslinked gel. The shearing force can be applied prior to and/or during blending of the gel with the thickener.
摘要:
Formulations or products are caused to be active antimicrobials by the addition thereto of at least one effective amount of at least one crystalline mixed metal hydroxide (MMOH) conforming substantially to the formulaLi.sub.m D.sub.d T(OH) (m+2d+3+na) (A.sup.n).sub.a.xH.sub.2 Owhere m is zero to one, D is a divalent metal, d is from zero to 4, T is a trivalent metal, A represents at least one anion or negative-valence radical, (m+2d+3+na) is equal or to greater than 3, (m+d) is greater than zero, and xH.sub.2 O represents excess waters of hydration. The MMOH forms an adduct with, an coats, the microbes, thereby deactivating the microbes.
摘要:
Disclosed is complex tolylene polyurea-thickened grease containing less than 7 parts per million 2,4-diaminotoluene and a process for making said grease comprising reacting an isocyanate, a polyamine and monoamine with a major portion of a lubricating oil and thereafter adding an alkaline earth metal oxide or hydroxide and a carboxylic acid anhydride containing 2 to 20 carbon atoms to said mixture and thereafter milling said mixture to the consistency of grease.
