Definitions
- the invention relates to a coating composition for molds and their use.
- the coating composition is suitable for cores and molds, especially those made using water glass as a binder.
- the coating composition comprises certain clay materials. Likewise, a method for sizing is claimed.
- Casting molds are obtainable from a refractory material, for example quartz sand, under molding into a casting mold and setting by means of a suitable binder in order to ensure sufficient mechanical strength of the casting mold.
- a refractory molding material for example quartz sand
- the refractory molding base material 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 carried out in each case by cold or hot processes.
- Cold processes are processes which are carried out essentially at room temperature without heating the casting mold.
- the curing is usually carried out by a chemical reaction, which is triggered for example by the fact that a gas is passed as a catalyst through the mold to be cured.
- hot processes the molding composition is heated to a sufficiently high temperature after molding to expel, for example, the solvent contained in the binder or to initiate a chemical reaction by which the binder is cured, for example, by crosslinking.
- Binder systems have been developed which can be cured by the introduction of gases. Such a system is for example in the GB
- the waterglass-based binder system consists of an aqueous alkali silicate solution and a hygroscopic base, such as sodium hydroxide, added in a ratio of 1: 4 to 1: 6.
- the water glass has a modulus S1O2 / M2O of 2.5 to 3.5 and a solids content of 20 to 40%.
- the binder system also contains a surface-active substance, such as silicone oil, which has a boiling point> 250 ° C.
- the binder system is mixed with a suitable refractory material, such as quartz sand, and then injected into a core box with a core shooter.
- a suitable refractory material such as quartz sand
- the hardening of the molding material mixture takes place by removal of the water still contained.
- the drying or hardening of the casting mold can also take place under the action of microwaves.
- inorganic binders also have disadvantages compared to organic binders, for example the known inorganic binders have a low stability of the casting molds produced therewith against high humidity or against water. For a storage of the molded body over a longer period, as usual with organic binders, not secured possible.
- 7,770,629 B2 proposes a molding material mixture which contains a water-glass-based binder in addition to a refractory molding base material. A proportion of a particulate metal oxide is added to the molding material mixture. Precipitated silica or fumed silica is preferably used as the particulate metal oxide.
- the methods described for the production of casting molds and cores usually also include the application of a refractory mold coating, which is also called sizing, at least on those surfaces of the basic mold which come into contact with the cast metal.
- a refractory mold coating which is also called sizing
- the purpose of the mold coatings is to influence the molding surface, to improve the casting appearance, to influence the casting metallurgically and / or to avoid casting defects.
- the commonly used sizing agents contain as base materials e.g. Clays, quartz, kieselguhr, cristobalite, tridymite, aluminum silicate, zirconium silicate, mica, chamotte and also coke and graphite. These precursors are the purportive part of the sizings which cover the mold surface and close the pores against the penetration of the cast metal.
- the surface of the casting mold can be modified and matched to the properties of the metal to be processed.
- the size can be used to improve the appearance of the casting by creating a smooth surface because the size compensates for irregularities caused by the size of the grains of the molding material.
- the sizing may metallurgically influence the casting by, for example, selectively transferring additives to the casting at the surface of the casting via the sizing which enhance the surface properties of the casting.
- the sizings form a layer which chemically isolates the casting mold from the liquid metal during casting. This prevents any adhesion between the casting and the casting mold so that the casting can be easily removed from the casting mold.
- the sizing can also be used to specifically control the heat transfer between the liquid metal and the casting mold in order, for example, to effect the formation of a specific metal structure by the cooling rate.
- the curing of the inorganic binder used is nowadays increasingly via a condensation reaction initiated by elevated temperatures, in which the formation of the binder bridges takes place via the splitting off of water.
- this is a reversible reaction, i. by contact and reaction with water, the bonds can be split again, with the extent of this back-reaction greatly different from the
- Process parameters for core production is dependent. Among the process parameters typically used in series production (fast cycle times, high temperatures), the casting molds lose their strength through contact with water and partly also through contact with alcohol, the surface softens and the casting mold loses its shape.

- amorphous silica was added, if necessary, with further stirring.
- the amorphous silica is pyrogenic silica from RW Silicium.
- the mixture was then stirred for an additional 1 minute.
- the molding material mixture was transferred to the storage bin, a H 2.5 hot-box core shooter from Röperwerk-G manmaschinen GmbH, Viersen, DE, whose mold had been heated to 180.degree.
- the molding material mixture was introduced into the mold by means of compressed air (5 bar) and remained in the mold for a further 35 seconds.
- compressed air 5 bar
- hot air 2 bar, 150 ° C on entering the mold
- the coating compositions were applied to the test bars by dipping, the application parameters are listed in Table 2.
- the test bars were coated either immediately after removal from the mold or after a 30 minute cooling time.
- the coated test bars were stored after application of the coating in a drying oven for 30 minutes at 150 ° C.
- test bars were placed in a Georg Fischer strength tester equipped with a 3-point bending device (DISA Industrie AG, Schaffhausen, CH), and the force was measured, which leads to the breakage of the test bars.
- the uncoated bending strengths were measured according to the following scheme:
- the flexural strengths were coated according to the following scheme:
- coated flexural strengths were measured according to the following scheme - 10 seconds after removal from the oven
- the quality of the inorganic cores and molds coated with these sizes is sustainably improved and, for example, storage stability of the cores and forms of several days can be achieved without problems.
- Particularly noteworthy is the fact that despite the unusually high solids content, the viscosity of the size is in a range which is usual for sizing.
- the size can be brought into the application state without the use of special additives or larger amounts of water.
