Definitions
- the present invention relates to a method for improving the release of hydraulic materials, in particular based on concrete, plaster or clay.
- Patent application DE-A-2 253 497 describes mold release compositions in the form of oil-in-water emulsions in which the mineral oil is partially replaced by triglycerides.
- triglycerides can only replace compounds of mineral origin due to their excessive reactivity and the risk of deactivation of the surface of the prefabricated part.
- Patent application EP-A-0 328 158 describes a mold release composition for concrete comprising esters of aliphatic carboxylic acids with mono- or dihydric alcohols, the total number of carbon atoms in the ester being 8 to 46 and esters having a melting point above 35 ° C. These products are advantageous from an environmental point of view but do not provide better performance than oils of mineral origin in terms of mold release.
- Patent application EP-A-0 561 465 describes a biodegradable mold release composition in the form of an oil-in-water emulsion comprising esters of hindered polyhydric alcohol and aliphatic carboxylic acids. However, the emulsion compositions generally require the introduction of surfactants stabilizing the emulsion.
- the ester can be a total ester, in which all of the hydroxyl groups are esterified. However, it can also be partial esters, having a certain number of free hydroxyl functions. Finally, the composition can also comprise complex esters, obtained by successive esterification in the presence of monocarboxylic acids and dicarboxylic acids. However, the latter are less sought after because of their high viscosity.
- the mold release composition comprises, in addition to the abovementioned ester, one or more terpene derivatives.
- the terpene derivative is present in the composition in a proportion of between 0 and 90% by weight, in particular from 10 to 70% by weight,
- the release composition further comprises an inorganic component.
- This mineral component can be a mineral solvent and / or a mineral oil.
- Solvents or mineral oils are understood to mean mixtures of hydrocarbons of mineral or synthetic origin, more or less heavy, containing mainly aromatic, paraffinic and cycloparaffinic hydrocarbons.
- release compositions described above can of course also contain additives customary in the material. Among these agents, mention may be made, for example, of wetting agents, anticorrosion agents, antioxidant agents, waxes and resins.
- a release composition particularly preferred in the context of the invention comprises 30 to 90% by weight, preferably 35 to 50% by weight of ester as defined above and from 10 to 70% by weight, preferably 50 to 65% by weight of terpene derivative.
- An especially preferred mold release composition consists of these two components, to the exclusion of any other additional component.
- the process improving the release of parts based on concrete, plaster or clay according to the invention comprises the application of a composition as described above on the mold.
- This application can be done by any means known to those skilled in the art, for example by spraying or application with a cloth.
- a particularly advantageous example of application is spray application.
- the consumption of the release composition, applied by spraying, is generally 50 to 100 m 2 / liter.
- compositions based on concrete, plaster or clay can be done in the usual manner.
- a pentaerythritol ester of tall oil fatty acid (Resinoline E 500, Terpene and Resinole Derivatives, France) is used.
- This product has a viscosity at 20 ° C of 175 cSt.
- the acid number measured is 15 mg KOH / g of product.
- a mold release composition is prepared by mixing at room temperature 4 kg of E 500 resinin and 6 kg of mixture of pine oil and terpene alcohols comprising from 88 to 93% by weight of terpene-ol alcohol (Dertol 90, Terpene and Resinoleic Derivatives, France).
- a mold release composition is prepared by diluting at room temperature 1 kg of the composition of the previous example with 1 kg of white spirit type solvent flavored (Spirdane D60, Total, France).
- the composition thus obtained has a viscosity at 20 ° C of 6.22 cSt and an acid number of 3.2 mg KOH / g of product.
- a mold release composition is prepared by mixing at room temperature 4 kg of pentaerythritol ester of tall oil fatty acid (Resinoline E 500, Terpene and Resinoleic Derivatives, France) with 6 kg of white spirit flavored solvent (Spirdane D60, Total, France).
- composition thus obtained has a viscosity at 20 ° C of 7.3 cSt and an acid number of 5 mg KOH / g of product.
- the composition thus obtained has a viscosity at 20 ° C of 15.6 cSt and an acid number of 3 mg KOH / g of product.
