Definitions
- the invention relates to mixtures of fatty substances containing fatty alcohols with 16 to 24 carbon atoms, wax esters and fatty ketones and their use as mold release agents.
- fatty acid esters and wax esters as environmentally compatible mold release agents, for example in the production of concrete or in the tire industry, has long been known and has been widely published. Because of their structure, however, the esters have a melting point which is generally too low for use as a mold release agent. Furthermore, with mold release agents which predominantly contain esters, there is a risk that they will be split in contact with alkaline substances or contribute to undesirable softening of the materials, for example certain plastics [Fat.Sci.Technol. 92, 473 (1991)].
- the object of the invention was therefore to develop new mold release agents which are free from the disadvantages described.
- the invention relates to fat mixtures containing
- Ri-OH (I) in which R * stands for a saturated, linear, optionally hydroxy-substituted alkyl radical with the following C chain distribution:
- R- ⁇ CO for an optionally hydroxyl-substituted acyl radical with 16 to 24 carbon atoms and 0 or 1 double bond
- R ⁇ stands for an optionally hydroxy-substituted aliphatic hydrocarbon radical with 16 to 24 carbon atoms and 0 or 1 double bond
- R ⁇ and R 5 independently of one another represent alkyl radicals having 15 to 24 carbon atoms.
- Fatty alcohols of the formula (I) which can be considered as component a) have 16 to 24 carbon atoms. Typical examples are cetyl alcohol, stearyl alcohol, 12-hydroxystearyl alcohol, arachyl alcohol and behenyl alcohol.
- the fatty alcohols can also be used in the form of technical cuts.
- Suitable starting materials for this purpose are, for example, methyl esters based on rape oil rich in erucic acid, peanut oil, castor oil, formulationdowowoa oil, beef tallow or fish oil which are subjected to high pressure hydrogenation. In this case, not only is there a reduction of the ester group to the hydroxyl function, but at the same time there is also extensive saturation of double bonds contained in the fat chain.
- Antifoam agents with particularly advantageous technical properties contain fatty alcohols in the C number range mentioned, which have iodine numbers below 10, preferably 0.1 to 5.
- Fatty alcohol mixtures which are components a) in a special way for the production of hydrolysis-stable mold release agents can be characterized by the following C chain distribution:
- Cig 35 to 71% by weight
- Fatty alcohols or fatty alcohol mixtures are particularly preferred which have a hydroxyl number of 180 to 200, a softening point above 55 ° C. and are obtained as a wake in the distillation of fatty alcohols based on beef tallow or rapeseed oil.
- Wax esters of the formula (II) which can be used as component b) are to be understood as the esters of Ciss-C24 fatty acids with Ciss-C24 fatty alcohols. Typical examples are the esters of palmitic acid, stearic acid, 12-hydroxystearic acid, arachic acid and behenic acid with cetyl alcohol, stearyl alcohol, 12-hydroxystearyl alcohol, arachyl alcohol and behenyl alcohol.
- the wax esters can also contain small amounts of unsaturated components, both in the fatty acid and in the fatty alcohol component. Wax esters are preferred which have an iodine number of less than 10, preferably from 0.1 to 5.
- Typical examples are stearyl stearate, stearyl behenate and behenyl behenate.
- Pure or technical fatty acids and corresponding fatty alcohols can be used to manufacture the products, which are esterified in a manner known per se.
- Fat ketones of the formula (III), which serve as component c), are known substances which can be obtained by the relevant methods of preparative organic chemistry. For their production, one starts, for example, from fatty acid magnesium salts which are pyrolyzed at temperatures above 300 ° C. with elimination of CO2 and water [DE-OS 25 53 900]. Typical examples are fatty ketones, for example, by pyrolysis of the magnesium salts of palmitic acid, stearic acid, arachic acid, behenic acid and their technical mixtures Tallow fatty acid. The use of stearone (pentatriacontanon-18) is preferred.
- the fat mixtures can typically contain the fatty alcohols in amounts of 50 to 98, preferably 70 to 90% by weight, the wax esters in amounts of 2 to 20, preferably 5 to 12% by weight and the fat ketones in amounts of 2 to 20 ⁇ contain 10 to 15 wt .-%.
- the stated concentration data are in each case based on the sum of components a), b) and c).
- the fat mixtures according to the invention are solid at temperatures up to 65 ° C. and form a homogeneous, lubricious, non-adhesive film in the melt; they are also easily biodegradable.
- Another object of the invention therefore relates to the use of the fat mixtures according to the invention as mold release agents in the construction, rubber and plastics processing industries.
- the formulations A, B and C represent a mixture of fatty substances with a wax-like consistency, which melt without decomposing when heated and form a lubricious film.
- Recipe C is according to the invention, recipes A and B are used for comparison. Legend :
- Cig 50% by weight
