Definitions
- the present invention relates to an inorganic filler suspension in polyester polyol and to the process for manufacturing this suspension.
- polyesters polyols in particular the polyesterdiols are raw materials used in the field of the manufacture of polyurethanes. Indeed, these are obtained by reaction with a compound comprising isocyanate functions and compounds comprising hydroxyl functions such as polyesterdiols. These polyesterdiols are obtained by reaction between a diol compound such as a glycol or a polyesterdiol with one or more diacids according to a conventional process for the manufacture of polyester. Such a process generally comprises an esterification step followed by a polycondensation step.
- reinforcing fillers such as inorganic particulate compounds. It is generally described that these fillers are added to the polyesterdiol or the isocyanate compound before carrying out the reaction leading to the polyurethane.
- One of the aims of the present invention is to provide stable suspensions of inorganic fillers in a polyesterdiol making it possible to manufacture polyurethane articles in which the inorganic filler is dispersed in a homogeneous manner making it possible to obtain good properties and a good appearance.
- the invention provides a stable suspension comprising as liquid medium a polyesterdiol compound and as dispersed particles, an inorganic particulate filler at a weight concentration of between 0.8 and 8%.
- the stable dispersion is obtained by addition of said particles in the polyester polyol esterification reaction medium or in the reaction medium at the start of the polycondensation step.
- the inorganic filler can be added directly to the medium, either in the form of a premix with the diol or, according to the preferred embodiment of the invention, in the form of a premix with at least part of the diacids.
- a very good dispersion and suspension of the inorganic filler particles in the polyesterdiol is obtained and therefore a very good dispersion in the polyurethane foam which will be obtained with this suspension.
- the process of the invention in particular the process for introducing the inorganic filler in the form of a mixture with the diacids, makes it possible to obtain a stable suspension. It is therefore possible with the process of the invention, to prepare suspensions based on polyesterdiol and to store them before their use for the manufacture of polyurethanes.
- This process also makes it possible to obtain stable dispersions at higher concentrations of inorganic fillers.
- the mixture of the filler with the diacids can be obtained by mixing the granules or powders of diacids with the particles of inorganic filler, at ambient temperature, for example, or at a temperature between room temperature and 120 ° C. It is also possible to coat the particles of inorganic filler with part of the diacids. This coating is obtained by heating the mixture to a temperature above the melting or softening temperature of the diacids.
- the coating of the particles of inorganic filler is advantageously carried out with a diacid comprising a number of carbon atoms less than or equal to 5 such as glutaric acid or a mixture of diacids containing a diacid comprising 5 atoms of carbon or less such as the mixture of diacids called AGS,

These diols can also be used as a mixture.
- dicarboxylic acids As an example of dicarboxylic acids, mention may be made of aliphatic diacids such as adipic acid, succinic acid, glutaric acid, suberic acid, azelaic acid, sebacic acid, penelic acid, the acids aromatics such as phthalic, isophthalic, terephthalic, naphthenic acids. Unsaturated aliphatic acids such as maleic acid, fumaric acid, itaconic acid. These diacids can be used individually or as a mixture.

- Unsaturated aliphatic acids such as maleic acid, fumaric acid, itaconic acid.
- the diacids used for the formation of polyesterdiol are advantageously constituted by a mixture of adipic acid and mixture of diacids called AGS obtained as a by-product in the process for the manufacture of adipic acid by oxidation of cyclohexanol and / or cyclohexanone and which comprises adipic acid, succinic acid and glutaric acid.
- the dispersions of polyesterdiols containing an inorganic filler are obtained according to a process comprising two stages, a first esterification stage and a second of polycondensation.
- the esterification step is carried out by mixing the diacids with diols, for example a mixture of ethylene glycol and diethylene glycol with a diol / diacid molar ratio of between 1.2 and 1.5.
- the reaction temperature in this first step is gradually increased during the progress of the reaction.
