Definitions
- the invention relates to a self-lubricating lubricant composition based on a polyurethane and a lubricant.
- DE-OS 29 13 781 describes a lubricant which consists of a mixture of high molecular weight polyethylene and a grease.
- DE-OS 28 30 136 describes a self-lubricating material which consists of polymethylpentene in a mixture with a lubricating oil.
- WO-96/26978 describes a self-lubricating composition described, which consists of a predominant portion of certain thermoplastic polymers and a minor portion of a lubricant. Suitable thermoplastic polymers are polyamides, polyesters, polyphenylene sulfide, polyoxymethylene, polyolefins, styrofoam polymers and polycarbonates.
- the object of the invention is to provide a self-lubricating plastic-based material which withstands the high temperatures prevailing in the operation of corresponding devices and can easily be brought to the lubrication point by casting processes.
- polyurethanes can be mixed with various types of lubricants in a favorable manner and materials are formed which have particularly favorable self-lubricating properties.
- the invention thus relates to a lubricant composition which contains a) a polyurethane and b) a lubricant.
- the lubricant composition according to the invention can be a pore-free, compact or a foamed material.
- the amount of lubricant contained in the lubricant composition according to the invention is, based on the finished material, about 1 to 70% by mass and in particular about 10-60% by mass.
- lubricants 1. Mineral oils, synthetic hydrocarbon oils, ester oils, polyglycol oils, alkylphenyl ether oils, silicone oils, perfluorinated polyether oils or mixtures thereof.
- Greases consisting of at least one of the oils listed under 1. and a consistency agent, eg. B. a metal soap, a metal complex soap, a urea thickener, a silicate thickener or a powder of polytetrafluoroethylene or other plastics.
- a consistency agent eg. B. a metal soap, a metal complex soap, a urea thickener, a silicate thickener or a powder of polytetrafluoroethylene or other plastics.
- a polyurethane is prepared in a conventional manner by reacting a polyol component (A component) with an isocyanate component (B component), this reaction taking place in the presence of a lubricant.
- the lubricant can either be added to the A component or added as a third component during processing using a mixing and dosing system.
- the A component of the polyurethane consists essentially of polyether diols or polyester diols, with customary additives for controlling the mechanical and chemical properties of the system being added;
- the B component consists of an isocyanate or a so-called prepolymer, which has been obtained by reacting a diol with an isocyanate.
- the usual ones are isocyanates aliphatic and aromatic isocyanates in question.
- a component and the B component are mixed together in a certain mixing ratio, the mixing ratio depends on the existing in the A component the number of OH groups present in the B-group Number of NCO groups'.
- the lubricant composition according to the invention is generally suitable for filling slide or roller bearings or lubricant deposits on linear guides or for similar applications.
- the lubricant composition is particularly advantageous over conventional oils and greases because it prevents the ingress of contaminants and withstands high acceleration forces without loss of lubricant.
- the lubricant composition is characterized by a particularly high temperature resistance and can be easily processed by casting.
- the lubricant composition can thus be processed in two ways:
- a particular advantage of the lubricant composition according to the invention and the molded parts produced therefrom is that it is "stick-slip-free" at low sliding speeds. Leakage of lubricants is also largely prevented, so that contamination of the environment can be prevented. This is particularly important for applications in the textile and food industry.
- Another advantage of the lubricant composition is that it does not contain any mineral components, such as molybdenum sulfide, graphite or the like, which often tend to form residues and are difficult to remove.
- Terathane 650 polyether glycol, MW about 650, OH number 175; Fa.
- Terathane 650 (polyether glycol, MW about 650, OH number 175; Fa.
- Fig. 2 is a roller guide with rollers and lubrication and wiping unit.
- FIGS. 1a, 1b and 2 show in particular the case in which molded parts produced with the composition according to the invention are prefabricated and then brought to a lubrication point.
- 1a and 1 each show in elevation a radial bearing 10 with an inner ring 11, an outer ring 12, bearing balls 13 and a two-part molded part 14a and 14b, with FIG. 1a showing the individual parts of the radial bearing 10 for a clearer representation, while FIG. 1b shows one assembled state of the radial bearing 10 shows.
- the two parts 14a and 14b of the molded part are provided in such a way that they separate the bearing balls 13 from one another and are each produced from the composition according to the invention.
- the lubrication and wiper unit 21 consists of a housing 21 a, in which a wiper 21 b is inserted.
- the housing 21 a is preferably a plastic housing.
- the wiper 21b inserted in the housing 21a is pressed against the track of the roller guide by a spring.
- the scraper is, for example, a lubricating felt which is soaked with oil through a housing bore.
- this scraper 21b can advantageously be produced from the composition according to the invention, whereby the advantages described above are achieved.
