Abstract
The invention relates to the field of casting, and in particular relates to a casting molding sand adhesive for improving the flowability. The casting molding sand adhesive is characterized by consisting of the following raw materials in parts by weight: 80-90 parts of clay, 5-7 parts of metal oxide, 100-110 parts of water and 10-15 parts of modified mixed plant oil. According to the casting molding sand adhesive, the added mixed metal oxide can improve the hygroscopicity resistance and the storage stability of a sand mold subjected to hot air solidification; the modified mixed plant oil and substances such as silicon and aluminum in the clay are fully mixed, so that the problem of low flowability of the clay can be well solved; the flowability of the adhesive is improved; and furthermore, only a small amount of plant oil is added, so that the production cost is lower.
Description
Technical field:
The present invention relates to casting field, relate to a kind of molding sand adhesive for casting increasing mobility in particular.
Background technology:
The binding agent of moulding in current Foundry Production, coremaking is mainly divided into organic and inorganic two large classes, organic binder bond (i.e. organic resin) adhesion strength is high, curing agent is liquid, be convenient to automation quantitatively produce, do not produce dust pollution during mulling, but organic resin sand produces toxic gas in casting process, as bioxin, ammonia, sulfur dioxide etc., environmental pollution is serious, and its cost is very high simultaneously.Inorganic binder meets the environmentally friendly requirement that the Party Central Committee proposes, current production using more is clay and waterglass, clay-bonded sand (mostly being wet type) is generally used for moulding, not high concerning its mobility coremaking, can not the comparatively complicated foundry goods of production external form.
Summary of the invention:
Technical problem to be solved by this invention is that overcoming existing technological deficiency provides a kind of molding sand adhesive for casting increasing mobility.
Technical problem to be solved by this invention adopts following technical scheme to realize:
Increase a molding sand adhesive for casting for mobility, it is characterized in that the weight portion of its constitutive material is: 80-90 part clay, 5-7 part metal oxide, 100-110 part water, 10-15 part modification mixed vegetable oil.
Further, described clay is calcium bentonite.
Further, described metal oxide comprises 50-60 part zinc oxide, 10-14 part calcium oxide, 2-4 part chromium oxide and 3-6 part aluminium oxide.
Further, described modification mixed vegetable oil is made up of the raw material of following weight portion: 80-100 part tung oil, 3-5 part sesame oil, 6-9 part olive oil, 5-8 part poly-vinyl alcohol solution, 1-2 part aluminum hydroxide solution, 6-11 part salicylic acid, 11-15 part Petropols, 3-5 part metabisulfite solution.
Further, described modification mixed vegetable oil preparation method is: tung oil is put into reactor, heating, then poly-vinyl alcohol solution and Petropols are added, stir while adding, then to add pH adjusting agent adjust ph be 8-9, and then add sesame oil, olive oil, heating aluminum hydroxide stir, finally add sodium sulphate and salicylic acid, stir and be cooled to normal temperature.
Increase a preparation method for the molding sand adhesive for casting of mobility, it is characterized in that comprising the following steps: that the water by clay and 60%-80% mixes, start agitator, heating, slowly add modification mixed vegetable oil and remaining water again, cool after stirring, add metal oxide.
In the present invention, the mixed-metal oxides added, resistance to water soak and the shelf stability of the rear sand mold of hot-air solidification can be improved, modification mixed vegetable oil fully mixes with materials such as sial in clay, the problem of clay mobility deficiency can well be made up, improve the mobility of binding agent, and only add small part vegetable oil, production cost is lower.
