Definitions
- the invention relates to a binder system based on water glass, consisting of an aqueous alkali silicate solution of the general composition: xSiO 2 .yM 2 O .zH 2 O, where M is the alkali ions Li + , K + or Na + and a hygroscopic base in a ratio 1: 4 to 1: 6 is added, the modulus Na 2 O / SiO 2 being 2.5 to 3.5 with a solids content of 20 to 40% and using 30% sodium hydroxide solution in an aqueous solution as the hygroscopic base is, as well as a core sand mixture and a process for its preparation.
- a binder system based on water glass, consisting of an aqueous alkali silicate solution of the general composition: xSiO 2 .yM 2 O .zH 2 O, where M is the alkali ions Li + , K + or Na + and a hygroscopic base in a ratio 1: 4 to 1
- binder contained in the binder system is used for production of core moldings for foundry purposes.
- Binder are part of it a molding material that, under certain conditions, such as moistening or swelling and silicate formation, the composite between the individual grains of sand.
- pure Swelling binders and ceramic binders also become chemical binders water based or synthetic resin based, which react chemically with each other and solidify in the process.
- the known binders are either not sufficiently stable or show undesirable side effects or waste products that the Endanger the environment. Have therefore proven to be a favorable compromise Waterglass-bonded molding materials have been shown to have dehydration form solid phases and thereby solidify. However, it is not always easy to control the hardening processes that they only enter the core box. In particular through There is a risk of using modern core molding machines early consolidation of the molding sand. This will make the required good flow properties of the sand when flowing in not reached in the core box.
- DE-OS 15 08 634 (Diamond Shamrock Corp.) discloses a binder for raw materials for the production of self-hardening casting molds and casting cores.
- the binder consists of sodium silicate with a molar ratio of Na 2 O to SiO 2 of 1: 1, 5 to 1: 3 and potassium hydroxide, which is added in the form of an aqueous solution.
- potassium hydroxide which is added in the form of an aqueous solution.
- hydrogen is released under an exothermic reaction, the setting time being shortened by adding potassium hydroxide.
- a heat supply from the outside is not provided, a further silicon-containing material, for example ferrosilicon, having to be added, the grain size of which, however, should be less than 0.15 mm. Rapid setting is therefore only possible under certain, narrowly limited conditions and the presence of several components that need to be carefully controlled.
- 1.0 to 2.0% sodium hydroxide solution is added to a molding material mixture to improve the processability in the wet casting process of water glass bentonite or water glass clay mixtures.
- the molding material consists of 0.5 to 1.0% starch and 2.0 to 4.0% clay, the rest being quartz sand.
- the molding compound is applied to the model, backfilled with filling sand and the finished green mold is chemically or thermally solidified. It is therefore green sand molds that are not suitable for mechanical core production.
- the test specimens produced therefrom are hardened by esterification during drying for 1 hour at 200 ° C.
- DE 29 09 107 describes a process for the production of bodies made of granular and / or fibrous material with sodium silicate or potassium silicate known as a binder, the A surfactant is added to the mixture of the material becomes.
- the surfactant can consist of a surfactant, silicone oil or a silicone emulsion in a quantity of at most 0.1%, calculated on the weight of material.
- the object of the present invention is to provide a binder system for mechanical core production by core shooting / core blowing to develop that easily in the dry process (in dry, powdered state) and can be processed has improved flowability and reduced setting time.
- the new binder system based on water glass consisting of an aqueous alkali silicate solution having the general composition: xSiO 2 ⁇ yM 2 O ⁇ zH 2 O, wherein the alkali ions Li +, K + or Na + are for M and is characterized in that it additionally contains a hygroscopic base contains.
- Sodium hydroxide solution in a ratio of 1: 4 to 1: 6 is advantageously used as the hygroscopic base. If the module Na 2 O / SiO 2 is 2.5 to 3.5 with a solids content of 20 to 40%, the molding sand is prevented from solidifying prematurely under all operating conditions. 30% sodium hydroxide solution in an aqueous solution is used as the hygroscopic base.
- a surface-active substance is added to control the hygroscopic properties.
- the core shooter consists of a vertically arranged one Housing A, to which a horizontal air inlet B is flanged is.
- the air inlet is via a large air inlet valve 1 controlled, with an increased air pressure in the air storage tank 5 is pending.
- When opening the air inlet valve 1 the air pressure enters the machine room 10 of the housing A, in which a slotted sand cylinder 6 is arranged vertically.
- the Sand cylinder 6 is connected to a sand reservoir 3, which can be emptied via a slide 4.
- Binder system with a conventional core shooter can be processed into high-strength moldings.
- the test specimens show an approx. 10% improvement in compressive strength when 0.2% silicone oil is added to the test mixture.
- the compressive strength would be increased even further.
