Description

Lubricant The invention relates to a lubricant, which consists of several Components.

The known lubricants often consist of mixtures of different Mineral oils. Substances of this type are not soluble in water. However, it is not uncommon suggest that lubricants come into contact with textiles and contaminate them. This risk arises, for example, with lubricated tn-clutch couplings or door locks in particular of motor vehicles. Often is that of the known lubricants outgoing risk of contamination, however also the reason why So far, lubrication has been completely dispensed with. This is for example This is the case with zippers sewn into garments, which experience has shown could become stiff over time due to insufficient lubrication. to the Removal of contamination caused by the known lubricants is Usually processing with a solvent or cleaning agent is necessary. However, this proves to be very cumbersome and costly and is therefore felt to be disadvantageous.

Starting from this, it is therefore the object of the present invention to To create a lubricant that can be washed out of textiles with water.

This problem is solved in a surprisingly simple manner by using a water-soluble carrier in which at least one lubricant is incorporated in fine distribution, the water-soluble carrier material about 75 - 95 parts by weight and the stored lubricant (s) Lubricants that contain residual weight percentages.

The water solubility of the high weight carrier enables washing out with water. The lubricants are thereby due to their small parts by weight practically washed out without leaving stains. Processing with a cleaning agent or solvent is more advantageous here Way not required. As tests have shown, the implementation is sufficient in practice normal washing. Another advantage of the lubricant structure according to the invention is in it too see that textiles or which are usually made of plastic existing accessories such as zippers etc., by the lubricant not to be attacked. For this reason, it is also possible in an advantageous manner Technical articles integrated directly into the textiles, such as B. zippers etc., which can become stiff over time and for which so far no suitable one Lubricant was available to properly lubricate, which is positive affects ease of use and service life. Another It can be used advantageously, for example, in the lubrication of gliders for curtains or the running channels of curtain rails exist. But also when used for Lubrication of moving parts to which textiles are frequently exposed, such as B. Xuto locks, towbars, etc., affects the opposite of the state of Technology s no risk of contamination is beneficial. The achievable with the invention Advantages are therefore particularly in an excellent economy see.

In further training of the overarching measures, several Lubricants of different particle sizes can be incorporated into the carrier. Because of the different particle sizes, they are more advantageous Way particularly good sliding conditions.

In a further development of the overriding measures, the GrEgerstoff a mono- or polyhydric alcohol and / or its ether and / or its ester. The use of poly- ethylene glycol as Carrier proved to be particularly preferred. Offer carriers of this type advantageously a stable, temperature-resistant over a wide temperature range Structure for storing lubricants. In addition, the desired Adjust the viscosity easily and simply using the molecular weight. A medium molecular weight out of 500 has proven to be particularly useful in experiments. This results in practically an ointment-like state of aggregation. By mixing several, each Different molecular weights having proportions of the same carrier can be in this case cover a large melting range at the same time in an advantageous manner. This ensures that the structure of the carrier material is not within a small temperature range can collapse, which has a wide field of application opened.

Another appropriate design of the overriding measures can consist in the fact that at least one lubricant in the form of a wax, such as a PE wax, ester wax or amide wax is present.

Substances of this type can be classified due to their particle shape and size Easily flush out in an advantageous manner. At the same time, in advantageously a temperature resistance of up to about 150 OC, so that the temperature resistance of the carrier material can be used within a wide range. Provided If higher temperature loads are to be expected, the waxes can be wholly or partially replaced by silica, thereby increasing the temperature resistance of the carrier can be used even further.

In a further expedient embodiment of the overriding measures can be at least one lubricant in the form of a fatty acid and / or its esters and / or whose amide are present. Substances of this type result due to their particle shape and - an excellent addition to wax.

Another advantageous measure can be that at least a lubricant is present in the form of polysiloxane. When using such a All in all, small lubricant proportions are sufficient, which corresponds to the proportion of the washable carrier and has a positive effect on the washout.

Further advantageous refinements and expedient further training of the overriding measures result from the remaining subclaims in Connection with the example description below.

Below are some particularly preferred embodiments explained in more detail.

Example I: Experience has shown that zips become stiff over time, which has a negative effect on user-friendliness and service life. This one Vbelstand can be remedied by lubrication with a suitable lubricant. The lubricant used for this purpose in tests consisted of 80 percent by weight Polyethylene glycol, 10 percent by weight polyethylene wax and 10 percent by weight erucic acid amide. The polyethylene glycol forms the carrier in which the polyethylene wax is incorporated and the erucic acid amide are incorporated as lubricants in fine distribution. The lubrication For this purpose, fabrics were under normal pressure and normal Temperature stirred into the carrier.

The polyethylene glycol had an average molecular weight of 500. Here resulted in an ointment-like state of aggregation, which a targeted application with the help of a small brush or spatula allowed and still to one good distribution resulted.

The average molecular weight of 500 was obtained by mixing several proportions of polyethylene glycol, each with a different molecular weight in the order of magnitude set from 200 - 10,000. This resulted in a high melting range. Even at temperatures of the order of 150 ° the structure was as the carrier serving polyethylene glycol has not yet collapsed. The upper limit of the In the present example, the polyethylene wax was exposed to heat. For improvement In terms of temperature resistance, the wax could simply be entirely or partially made up of silica be replaced.

Long-term tests have shown that the lubricant used neither the zipper made of plastic nor the surrounding one made of a mixture attacks textile material consisting of natural fibers and synthetic fibers. One on purpose Any lubricant leak applied to the textile material could be left with no residue Wash out using tap water. The use of heated water of about 45 ° has proven to be particularly useful.

The zippers smeared with the lubricant had one extremely low running resistance. Even stiff zippers were through one Very easy lubrication within a very short time. This is due to the favorable particle size and shape of polyethylene wax and Recirculated erucic acid amide. By adding silica, its particle size is in the range between the particle size of polyethylene wax and erucic acid amide, an improvement could be achieved here. The addition of silica was about 2 - 3 percent by weight and was at the expense of the proportion of polyethylene wax.

Example II: In parallel long-term tests with a lubricant Consists of 90 percent by weight polyethylene glycol, 9.8 percent by weight polyethylene wax and 0.2 weight percent silicone oil, there were similar effects in terms of benefits as in example 1. It should be noted that the washing process is even easier here than in Example I. This is attributed to the fact that an even higher Proportion of carrier is present. This was through the use of silicone oil possible. Even with the recipe according to Example II, the wax can be wholly or partially replaced by silica.

A preferred device for lubrication is strip-shaped below Elements such as zippers and the like, explained in more detail with reference to the drawing.

The lubricating device shown in the drawing comprises a Storage space 1 for lubricant, through a wall provided with perforations 2 3 is separated from a work space 4, which houses an applicator roller 5 and penetrated by an insertion slot 6 running transversely to the axis of rotation of the applicator roller 5 is, through which a zipper 7 fastened to a fabric strip 9 can be passed is. The application roller 5, which is advantageously designed as a brush roller, is like this dimensioned and arranged that they the wall 3 in the area of the perforations 2 strips off and the lubricant emerging from the perforations 2 into the area of the insertion slot 6, d. H. to the zipper 7 transfers. The applicator roller 5 is made by the tangentially movable zipper that can be brought into engagement therewith 7 set in rotary motion.

The work space 4 with the rotatably mounted discharge roller 5 is shown in FIG a dimensionally stable housing 11 containing the perforated wall 3, can be plugged or screwed onto the housing 14 accommodating the storage space 1 is. The housing 14 can be designed simply as a tube or a rubber-elastic bottle be, so that the lubricant contained therein simply by pressing together accordingly the walls can be pressed out. But it would also be conceivable to use a Provide a spring or a threaded pin actuatable extrusion piston. In this case is the perforations 2 expediently a shut-off device in the form of a slide or the like assigned. The clear width of the perforations 2 is dimensioned so that that the lubricant particles embedded in the carrier material do not clog them can.
