Description
The present invention relates to foundry engieering, a kind of moulding, binder for core-making-modified water glass are provided especially.
Along with development of modern industry, the mankind more and more pay attention to the consumption of the energy, material, the protection of environment.Foundry Production always is one of comparatively serious industry of environmental pollution, and wherein the binding agent of manufacturing mold core is one of pollution sources.The challenge that is faced with competition of the binder for casting of many, the harmful environmental protection of those cost height, energy consumption.Waterglass is introduced Foundry Production at early fifties, does type, core binding agent, substitutes clay dry type technology at that time, and puts it over waterglass CO very soon
2Method was once becoming one of main technology of Foundry Production.Occurred various self-setting silicate process technologies later on again, its main curing agent has: cement, ferrosilicon powder, red mud, slag etc.But these technologies have a common shortcoming, i.e. waterglass addition height, and type, core collapsibility are poor, and casting quality is bad, and old sand is difficult for regeneration.Because waterglass addition height (can reach 7～9% sometimes), the waterglass film of sand grain surface be (800～870 ℃) fusing at high temperature, forms continuous vitreum fused mass, after the cooling sand grains is sticked together securely, this is the root of water-glass sand shortcoming.For improving the collapsibility of water-glass sand, various countries founder author has done big quantity research, develop the waterglass of various modifications, modifier comprises dextrin, sugar, molasses, Sodium Polyacrylate, polyacrylamide, sodium phosphate trimer, cellulose (carboxymethyl cellulose rope, carboxylic propyl group fiber rope), humic acid, sodium humate, oxidizing glucose etc.Should be noted that these modifier have improved the collapsibility of water-glass sand to some extent, but all less than the basic shortcoming of eliminating water-glass sand.From the sixties, foundry resin is widely applied, and that resin sand has is efficient, energy-conservation, improve advantages such as casting quality, the renewable reuse of old sand, thereby has replaced the dominant position of water-glass sand.The application of resin sand has significantly promoted the progress of foundry engieering, but has also exposed some new problems.As: producing some in the production has the gas of penetrating odor, formaldehyde, amine gas, SO
2, benzene class, hydrocarbon gas, contain the gas of cyanide, these gases not only are detrimental to health, and cause environmental pollution, the especially discharging of pipe resin antiquated sand, the harm ecological balance.Along with the attention of various countries, cause that more numerous founders author pays close attention to environmental protection.Add the resin price costliness, the castings production cost is improved, corporate profit margin descends.Reason in sum, many founder authors take up to sodium silicate binder again.The research of ester sodified water glass sand descends the waterglass addition significantly, for the collapsibility of improving water-glass sand has been created condition.The present invention of day nineteen eighty-three waterglass VRH method hardening process, the nontoxic making core with aeration ossification method of waterglass had been invented by China in 1997, much go into to have carried out the research that makes the sclerosis of waterglass core with heating using microwave in recent years, further promoted the improvement of sodium silicate binder.New page is opened in the large-scale popularization application that is waterglass after 2000.
The object of the present invention is to provide a kind of modified water glass for casting, it has the intensity height, and collapsibility is good, and is with low cost, is used as the quality that binder for casting can improve foundry goods, helps environmental protection.
The invention provides a kind of modified water glass for casting, it is characterized in that: this modified water glass is by the xylitol modification, and the main chemical mass percent is (except that specifying, being mass percent)
