Definitions
- the invention relates to molding material mixtures for the production of molds, cores or feeders for metal casting comprising at least one refractory molding material, a binder based on an alkaline resole resin and at least one sugar surfactant. Furthermore, the invention relates to a process for the production of molds and cores using the molding material mixtures as well as molds, cores and feeders produced by this process.
- Molds are essentially composed of molds and molds and cores, which represent the negative mold of the casting to be produced.
- These forms and cores usually consist of a refractory base molding material, such as quartz sand, and a suitable binder, which gives the mold after removal from the mold sufficient mechanical strength.
- the refractory molding base material is preferably in free-flowing form, so that it can be filled into a suitable mold after mixing with the binder, compacted and then cured. After curing, the binder provides for a firm cohesion between the particles of the molding base material, so that the casting mold obtains the required mechanical stability.
- Molds form the outer wall of the casting during casting, cores are used to form cavities within the casting. It is not absolutely necessary that the forms and cores are made of the same material. For example, in die casting, the outer shape of the cast pieces is carried out using metallic permanent molds. Also possible is a combination of molds and cores made from differently blended molding compounds and by different processes. Feeders are voids in the mold, which are filled with liquid metal during casting together with the casting. The feeder keeps the metal in it liquid for a longer time and can thus compensate for a volume deficit in the solidification phase of the casting. If, in simplification terms, only kernels are discussed below, the statements apply to the same extent to molds and feeders based on the same molding material mixture and produced by the same process.
- organic, inorganic and mixed organic / inorganic binder can be used, the curing of which can be done by cold or hot process.
- Cold processes are those processes which are carried out essentially without heating the mold used for core production, generally at room temperature or at a temperature caused by a possible reaction.
- the curing takes place, for example, in that a gas is passed through the molding mixture to be cured and thereby initiates a chemical reaction.
- hot processes the molding material mixture is heated to a sufficiently high temperature after molding, for example by the heated mold, to expel the solvent contained in the binder and / or to initiate a chemical reaction by which the binder is cured.
- alkaline phenolic resins as binders for molds is known per se and these are disclosed for example in EP 0323096 B2 and in EP 1228128 B1. These are alkaline resole resins that can be cured by introducing CO2.

- concentration of binder within the casting mold can vary.
- Resoles in the sense of the present invention are aromatics which are linked to one another via methylene groups (-CH 2 -) groups and / or via ether bridges (especially -CH 2 -O-CH 2 -) and which each carry at least one -OH group (phenol compound).

- the molar ratio of boron to phenol is more preferably in the range 0.1: 1 to 0.5: 1.
- organic aluminum, boron or tin compounds can also by introducing organic boron, aluminum and tin compounds such as aluminum alcoholates of the formula AI (OR) 3, wherein R can be independently a saturated or unsaturated, branched or unbranched hydrocarbon radical having 1 to 10 carbon atoms.
- a solution of a boron compound such as boric acid or boric acid ester in brine is suitable as a solution of boron-containing oxyanion.
- the solution used is a solution of a base in water, which is also used for mixing with the resole resin.
- both organic bases e.g. Amines or ammonium compounds as well as inorganic bases such as e.g. Alkali metal hydroxides

- the molar ratio of hydroxide ions to the phenol group in the binder system is preferably 0.5: 1 to 3: 1, preferably 1, 0: 1 to 2.5: 1. It is not necessary that the entire amount of base is added already at the beginning of the condensation; Usually, the addition takes place in two or more substeps, wherein a part can be added only at the end of the manufacturing process. Mixtures of basic catalysts can also be used.
- alkaline resoles The preparation of alkaline resoles is e.g. in EP 0323096 B2 and EP 1228128 B1. Further resol-based binders are described, for example, in US Pat. No. 4,426,467 and US Pat. No. 4,474,904.
- the resole contains water, preferably in an amount of 15% by weight to 50% by weight, based on the binder.
- water In the final part of the binder are resole, water, alkalis and oxyanion.
- the water may originate from aqueous solutions which are used in binder preparation, but on the other hand it may also be added separately to the binder or be obtained as condensation water from the resol condensation.
- water also serves, for example, to impart to the binder an application-specific viscosity (25 ° C.) of from 5 to 1200 mPas, preferably from 10 to 1100 mPas and particularly preferably from 10 to 950 mPas.
- the viscosity is determined using a Brookfield Rotational Viscometer, Small Sample Method, Spindle No. 21 at 100 rpm and 25 ° C.

- esters suitable for curing the resols are known to those skilled in the art, e.g. from US 4426467, US 4474904 and US 5405881. They include lactones, organic carbonates and esters of C1 to C10 mono- and polycarboxylic acids with C1 to C10 mono- and polyalcohols. Preferred but non-limiting examples of these compounds are gamma-butyrolactone, propylene carbonate, ethylene glycol diacetate, mono-, di- and triacetin, and the dimethyl esters of succinic acid, glutaric acid and adipic acid including their known under the name DBE mixture. Due to different saponification rates of the individual esters, the curing speed of the sole runs at different rates depending on the ester used, which can also influence the strengths. By mixing two or more esters, the desired cure time can be varied within wide limits.
