Definitions
- the present invention relates to a composition for treating leather Process for their preparation and their use for hydrophobing and / or Softening leather.
- Water-soluble hydrophobic fatliquoring formulations contain the hydrophobierenden components emulsified or dispersed in a water phase. Many of the Emulsifiers used for this purpose have an effect due to their hydrophilic moieties Water repellency, which leads to insufficient water repellency of the leather.
- silicone oils without or with functional groups, such as OH, carboxy and Amino groups as well as halogen substituted polymers, e.g. Fluorocarbon compounds used. These have the disadvantage that they are often solvent-containing or even in Solvents must be applied. Also, the required waterproofness is sufficient Of the leather produced with it often not enough.
- fatty polyacrylates are used today. These cause a hydrophobing and at the same time softening effect. Their effect is enhanced by additional Use of silicone oils or functional silicone oils in the leather treatment agent (EP 1 087 021 A1). Disadvantage of these fatliquors is that the leather produced with it too much are soft, the typical "rubbery" handle acrylate-based fatliquor effect and thus for certain applications, e.g. for permanent shoe upper leather, not or only can be used proportionally.
- the present invention is therefore based on the object, an aqueous liquor to provide usable leather treatment agent for hydrophobing and / or Softening leather without the disadvantages of the prior art can be used can.
- the reaction product from the reaction of phosphating agent with the abovementioned OH components siloxane and furthermore alcohol and / or alcohol polyglycol ether is used, ie there is a phosphoric acid ester mixture in the composition according to the invention.
- a phosphating agent is understood to mean any agent that is capable of forming phosphoric acid esters with the OH components.
- the phosphating agent is P 2 O 5 , with which the phosphating reaction can be carried out in a particularly favorable, simple and rapid manner.
- the phosphoric acid esters are
- the ortho-phosphoric acid in particular derived from the ortho-phosphoric acid. It can be mono-, di- and triester act.
- the OH components used for the reaction with the phosphating agent are it is a mixture containing the above-described siloxanes and further either a C10-C40 alcohol or a C10-C40 alcohol polyglycol ether or both a C10-C40 alcohol as well as a C10-C40 alcohol polyglycol ether.
- the phosphoric acid ester mixture of the composition according to the invention can, as described above, by phosphating a mixture of the aforementioned OH components getting produced. But it is also possible in the inventive Composition each prepared separately with the respective OH components Use phosphoric acid ester.
- composition of the invention is the ⁇ , ⁇ -dihydroxypoly-C1-C4-alkylsiloxane the compound ⁇ , ⁇ -dihydroxypolydimethylsiloxane, with the in terms of their properties, in particular with regard to the hydrophobing and the Plasticizing, particularly advantageous composition of the invention is obtained.
- the viscosity of the siloxane is about 500 mPas. Siloxanes with this viscosity give, in particular with regard to the hydrophobic effect and the plasticizing Properties, particularly advantageous compositions according to the invention.
- Phosphoric acid ester mixtures can in the Phospatleitersrefractress several, from each other various C10-C40 alcohols are used.
- it may be primary Alcohols act.
- the alcohols are (i) unsaturated, especially simple unsaturated C12-C20 fatty alcohols, in particular cetyl alcohol and oleyl alcohol, or Mixtures of 2 or more of these, for example a mixture of cetyl alcohol and Oleyl alcohol in the ratio 1: 1, (ii) branched or unbranched saturated C20-C40 alcohols, for example, C30-C38 Guerbet alcohol, and (iii) saturated C10-C18 alcohols or mixtures from 2 or 3 of the alcohols (i) to (iii).
- the C10-C40 alcohol polyglycol ethers are preferably those derived from the C10-C40 alcohols described in more detail above, in particular the alcohols (i), (ii) and (iii) are derived.
- Alcohol polyglycol ethers have units derived from alkylene oxide of 0.5 to 10 moles. When Alkylene oxides can be used ethylene oxide, propylene oxide and mixtures thereof.
- the preparation of the phosphoric acid ester mixture used in the composition according to the invention can be carried out by initially charging the abovementioned OH components in a reaction vessel. If one of the OH components is solid, it may be necessary to melt it. Optionally, the mixture of the submitted OH components can be heated to about 40 ° C.
- the phosphating agent for example P 2 O 5 , is introduced into this mixture.
- the phosphating reaction is exothermic, the reaction temperature can rise to 80 ° C to 85 ° C. If it rises to over 85 ° C, it is favorable to carry out a cooling.
- the phosphating reaction can be carried out under a protective gas atmosphere, such as N 2 .
- the reaction temperature for the phosphating may be 70 ° C to 80 ° C.
- the reaction can be carried out with stirring. Conveniently, the reaction is stopped after completion of the phosphoric acid ester formation. This can be the case after about 5 to 6 hours.
- the phosphating agent P 2 O 5 is favorably used based on the OH groups of the OH components in a molar ratio of 1: 2 to 1: 3 (n P 2 O 5 : n OH groups). As a result, as complete as possible conversion of the phosphating agent is achieved.
- the amount of the siloxane is desirably 50% by weight to 60% by weight, based on the the phosphating reaction used mixture of OH components.
- the rest on 100% by weight, based on the mixture of the OH components used in the phosphating reaction, may then be the C10-C40 alcohol and / or C10-C40 alcohol polyglycol ether form.
- the above mixture of the OH components A, B, C and D may be 30 wt .-% to 40 wt .-% A, 5 wt .-% to 10 wt .-% B, 2 wt .-% to 4 wt .-% C and 50 wt .-% to 60 wt .-% D, wherein the amounts are based on the mixture of OH components are related.
