Description

A kind of environment-friendly type sandbinder
Technical field:
The present invention relates to casting field, relate to a kind of environment-friendly type sandbinder 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, waterglass may be used for coremaking, low price, nonpoisonous and tasteless, all compare environmental protection in moulding, coremaking and casting process, but its sand mold collapsibility is poor.
Summary of the invention:
Technical problem to be solved by this invention is that overcoming existing technological deficiency provides a kind of environment-friendly type sandbinder.
Technical problem to be solved by this invention adopts following technical scheme to realize:
A kind of environment-friendly type sandbinder, is characterized in that being made up of the component of following weight portion: 100-110 part modified pulp waste liquid, 0.5-1 part ammonium persulfate, 0.5-1 part are oxidized two acyls, 12-16 part sepiolite, 6-11 part Isooctyl acrylate monomer, 1-2 part barium sulfate, 2-4 part sodium silicate aqueous solution, 8-12 part potassium oxide, 1-3 part phenolic resins, 15-22 part ethanol, 2-4 part hexamethylenetetramine.
