Definitions
- the invention relates to a molding material mixture for the production of moldings for the foundry industry, a method for producing a casting mold using the molding material mixture, a casting mold, and the use of the casting mold for metal casting.
- Molds for the production of metal bodies are essentially produced in two embodiments.
- a first group are the so-called nuclei and forms. From these, the mold is assembled, which is essentially a negative mold of the casting to be produced, wherein cores serve to form cavities in the interior of the casting, while the molds depict the outer boundary. Often, the inner cavities are imaged by cores, while the outer contour of the casting is represented by a green sand mold or a steel mold.
- a second group form hollow body, so-called feeders, which act as compensation reservoir. These take up liquid metal, whereby appropriate measures are taken to ensure that the metal remains in the liquid phase longer than the metal that is in the negative mold forming mold. If the metal solidifies in the negative mold, liquid metal can flow out of the compensation reservoir to compensate for the volume contraction that occurs when the metal solidifies.
- Casting molds are made of a refractory material, such as quartz sand, whose grains are connected after molding of the mold by a suitable binder to ensure sufficient mechanical strength of the mold.
- a refractory molding material which is mixed with a suitable binder.
- the molding material mixture obtained from molding material and binder is preferably present in a free-flowing form, so that it can be filled into a suitable mold and compacted there.
- the binder produces a firm cohesion between the particles of the molding base material, so that the casting mold obtains the required mechanical stability.
- both organic and inorganic binders can be used, the curing of which can be effected by cold or hot processes.
- Cold processes are processes which are carried out essentially at room temperature without heating the molding material mixture.
- the curing is usually carried out by a chemical reaction, which can be triggered, for example, by passing a gaseous catalyst through the molding material mixture to be cured, or by adding a liquid catalyst to the molding material mixture.
- hot processes the molding material mixture after molding on a heated sufficiently high temperature, for example, to drive off the solvent contained in the binder, or to initiate a chemical reaction by which the binder is cured by crosslinking.
- organic binders such as e.g. Polyurethane, furan resin or epoxy-acrylate binders used in which the curing of the binder is carried out by adding a catalyst.
- Polyurethanes based on polyurethanes are generally composed of two components, a first component containing a phenolic resin and a second component containing a polyisocyanate. These two components are mixed with the molding base stock and the molding mixture is rammed, compressed, blasted, shot or otherwise, compacted and then cured.
- the catalyst is introduced into the molding material mixture, a distinction is made between the "polyurethane no-bake process” and the "polyurethane cold-box process”.

- the polymerization must be correspondingly slow run so that not already in the storage containers or supply lines hardening of the molding material mixture.
- the curing should not be too slow to achieve a sufficiently high throughput in the production of molds.

- the components are diluted with solvents.
- aromatic solvents are used, which, however, may have a harmful effect.
- the binder decomposes under the action of heat of the liquid metal. When pouring therefore occurs a strong smoke smoke. The exhaust gases produced during casting must therefore be removed by a complex venting and worked up in order to comply with environmental and occupational safety regulations.
- EP 0 771 599 describes a polyurethane-based binder system which contains methyl esters of higher fatty acids as solvent. Particularly suitable is Rapeseed oil methyl ester used as the sole solvent.
- EP 1 137 500 B1 describes a polyurethane-based binder system in which the phenolic resin component or the polyisocyanate component comprises a fatty acid ester which is esterified with an alcohol which has a high carbon number. Particular preference is given to using fatty acid butyl esters and fatty acid octyl or fatty acid decyl esters.
- the phenolic resin component comprises an alkoxy-modified phenolic resin in which less than 25 mole% of the hydroxymethanol groups are etherified by a primary or secondary aliphatic monoalcohol having from 1 to 10 carbon atoms. Of the Solvent content of the phenolic resin component is at most 40% by weight.
- fatty acid esters which are esterified with long-chain alcohols, can significantly reduce the smoke and smoke during casting. Nevertheless, there is a constant search for further possibilities to further reduce emissions during casting. Among others there are two possibilities. As a first possibility, the components of the binder can be changed so that they lead to a lower smoke development. As a second possibility, the binder may be modified to have a higher bonding power, i. the proportion of the binder in the molding material mixture can be reduced.
- the invention therefore an object of the invention to provide a molding material for the production of moldings for the foundry industry, which allows the use of small amounts of binder, the production of moldings, which have a sufficiently high strength, even in a technical production safely and without Damage to be handled.
- carboxylic acid diesters of a branched alkanediol have both a good compatibility with the polyisocyanate component and with the polyol component, so that the components of the binder system can be dissolved in a relatively small amount of solvent. In most cases, it is not necessary to add aromatic solvents to the carboxylic acid diester of a branched alkanediol in order to reduce the solubility of the components of the binder system to polyisocyanates.
- the amount of solvent in the binder system can be kept low and on the other hand, the viscosity of the binder system or its components is lowered so far that the grains of the refractory molding material can be evenly coated with a thin layer of the binder system at low mixing times , This is very important, for example, in the no-bake method, since in this case the liquid catalyst is added to the binder system and therefore the processing time of the molding material mixture is relatively short before the binder cures.
- Aromatic solvents are to be understood as meaning aromatic hydrocarbons, such as toluene, xylene and, in particular, high-boiling aromatic hydrocarbons having a boiling point of more than 150 ° C.
- the inventors assume that the carboxylic acid diesters of branched alkanediols used in the binder system of the molding material mixture according to the invention are not useful because of their oxygen content -aromatic character compared to aromatic solvents tend significantly less smoke and smoke.
- the moldings produced and cured therefrom have a high mechanical stability. This means in a technical application that the proportion of the binder in the molding material mixture can be lowered, and yet the desired strength of the molding remains. By reducing the requirement for adequate mecha- niche stability of the mold required binder amount, the smoke and smoke during casting can be further reduced.
