DE398879C - Process for making neutral, solid colloids and consistent lubricants - Google Patents

Description

Method of making neutral, solid colloids and more consistent Lubricant. In the main patent is a process for producing more neutral, more solid Wax and resin colloids described after using the wax or resin with heating or without pressure with aqueous solutions of lactic acid salts, mainly thickened ones Alkali lactate solutions are stirred until the two are homogeneously combined @Components indicates the formation of the suspensoid.

It has now been shown that the usability of aqueous solutions not limited to lactate solutions in the manner characterized by the main patent is, but that also other aqueous solutions that are not dryable than Components of the colloids can be used. As such come for example Solutions of magnesium acetate, magnesium chloride ,. Calcium chloride into consideration. One There is just as little saponifying effect in these solutions as in the main patent in Ask how the acidic or alkaline reaction of the solution plays no role at all.

The addition of salt solutions to consistent fats has already been repeated has been proposed. For example, there is a patent specification for a method to remove fat by adding caustic soda and concentrated saline solutions to make them consistent. After another, a mixture of, wool fat and antimony butter becomes a zinc chloride solution added to the deterioration affecting the conductivity of the antimony butter at higher temperatures suffers to pick up again, i.e. to win a mixture, that conducts electricity well at any temperature. In an Austrian Patent highly concentrated viscous emulsion compositions are described, which made from various resinous and oily substances with sulphite pulp waste liquor are. These mixtures can be used for various purposes with additives such as sawdust, Tanning agents, metal salts and oxides. Acts in all of these cases it is therefore a matter of masses, which are quite specific, of what is present here completely divergent purposes are composed, whose properties are from those of the fixed Colloids are different and their composition is not suitable either would be for the same purposes as the solid colloids described in this application to serve.

Compared to the aforementioned method, the present invention aims to produce consistent fats, which in addition to resinous and oily masses to a considerable extent Part of water contained in the form of a saline solution. It has been shown that so produced colloidal fats are excellent lubricants, which in relation to their Ability to reduce the friction between sliding metal surfaces as well How to reduce the heat development that occurs here, that only from fats and resins are equal to or even better than existing lubricants.

Examples: i. io parts of Rolunontan wax are melted and under Stir with 50 parts of warmed magnesium chlorine solution of about 25 to 30 percent magnesium chlorine in a thin stream until the components that initially remain separate have united homogeneously, which is clearly recognizable from the outside. laugh your cold the colloid is present as a solid, uniform body.

The chlorine magnesium solution is expediently magnesium oxide or beforehand Magnesium hydroxide in an amount of about 1:, percent of the weight of the chlorine magnesium solution fed. The hydroxide or oxide can be generated in the solution itself.

2. Instead of the chlorine-magnesium solution, exactly the same and with the same can be used Successfully use an approximately 25 percent magnesium acetate solution. Here too it is advisable to add the magnesium oxide or hydroxide.

Such colloids can be further processed by they, with Ü1 and fat, z. B. Tran, rapeseed oil o. The like., Or with other organic solvents brings together and dissolves in it, preferably with heating and stirring, whereby one then possibly other organic bodies, such as pitch, anthracene residues, slack, paraffin masses and the like, with dissolves. In this way, consistent lubricants, pastes and ointments are obtained.

Matt can also be used in place of further processing of the colloid, such as it has just been described, make the pastes etc. from the start by inanan the 1: i1-formation of the suspensoid in the solvents (oils and fats etc.) does it himself.

It has also been shown that the waxes, resins, pitches, hydrocarbons etc. can be partially or completely replaced by wool fat or, more appropriately, by the raw wool fat alcohols (these are the wool fat alcohols including the unsaponifiable ones Proportions of wool fat) and also the purified 'Vollfettalkolt o1 e.

Claims (1)

PATENT CLAIMS: i. Embodiment of the process of the main patent for the production of neutral, solid colloids, characterized in that waxes, resins, solid Koblenwasserstoffe, pitch, wool fat or wool fat alcohol instead of lactate with aqueous, non-drying solutions, z. B. ivässi "er lIagnesiutnchlorid solution or magnesium acetate solution, treated" earth. For example, embodiment according to claim 1, characterized in that an additive of magnesium oxide or hydroxide is added to the solution of the magnesium salt. 3. Process for the production of consistent lubricants, pastes and ointments, characterized in that the solid colloids prepared according to the method of claim i are dissolved with heating and vigorous stirring or kneading in oils and fats, as well as other organic solvents (oil, rapeseed oil or the like), in which possibly others organic bodies such as pitch, anthracene residues, slack, paraffin masses and the like are dissolved 4. Embodiment of the method according to Claim 3, characterized in that the formation of the suspensoid is carried out in the solvents themselves.
