Abstract
The invention provides water-glass sand and preparation and use methods thereof in order to solve the problems of poor liquidity and the like of the water-glass sand. The main components of the water-glass sand comprise crude sand, water glass, foaming agents, auxiliary materials and the like. By cooperation with the methods of pre-foaming or mixed foaming, the novel water-glass sand good in liquidity and other performance and a sand mould and sand core thereof are obtained. While the inherent advantages of cleanliness, environmental protection, low cost, high strength and the like of the water-glass sand are retained, the problems of poor liquidity and the like of the water-glass sand are solved to the great extent, the good collapsibility, special thermophysical performance and the like can be given to the water-glass sand, and the water-glass sand and the preparation and use methods thereof are a novel environment-friendly cast material and casting method adapting to modern foundry production.
Description
Technical field
The invention belongs to casting field, a kind of water-glass sand and preparation and application thereof are provided.
Background technology
Along with the development of society, people's environmental consciousness improves constantly, day by day urgent to the requirement of energy-saving and emission-reduction, cleaner production.All the time there is serious problem of environmental pollution in foundry industry, realizing its cleaner production will be following research emphasis.
Casting is the basis of machine industry.In castings production, sand casting is with a long history, and Technical Economy is excellent, flourishing long time, and in modern Foundry Production, the share of sand casting is more than 80%, and sand casting usually has irreplaceability in the foundry goods device fabrication of complex appearance and inner chamber.
Water-glass sand is the representational sand casting molding sand of most, core sand, and have the advantages such as pollution is little, good manufacturability, good economy performance, water-glass sand casting is typical Green foundry technique.Meanwhile, because waterglass has, surface tension is large, viscosity high, the water-glass sand poor fluidity made.The modern Foundry Production of very difficult adaptation is in enormous quantities, high efficient production is complicated, accurate casting mold, core.By reducing to modifying water glass the mobility that waterglass viscosity can improve water-glass sand to a certain extent, but it is very limited to improve degree, be difficult to in enormous quantities, high efficient production is complicated, accurate casting mold, core.
Summary of the invention
The present invention adds blowing agent in water-glass sand, and then the performance such as the mobility improving water-glass sand.
The present invention is directed to the problems such as the poor fluidity of water-glass sand existence, propose a kind of New Type Silicate sand and preparation and application thereof.
The object of the invention is to be achieved through the following technical solutions:
Water-glass sand of the present invention by roughing sand, waterglass, blowing agent, auxiliary material through mixing, mass fraction ratio=100:(0.5 ~ 8 of roughing sand, waterglass, blowing agent, auxiliary material): (0.005 ~ 20): (0 ~ 15).Wherein: roughing sand is a kind of in silica sand, quartz sand, zircon sand, magnesia, emergy, Al-Si Refractory Materials sand, chromite sand, olivine sand, limestone sand, graphite sand, artificial nice foundry sand or their mixture; Waterglass is light water glass or modified water glass, and modulus is 1.0 ~ 4.0; Blowing agent is also called foaming agent or foaming agent, refers to and can promote that foam occurs, the material of formation closed pore or even pore structure material.Blowing agent kind is one or more in soap surfactant, alkyl sulfate surfactants, alkylaryl sulfonate surfactants, cationic surface active agent, nonionic surface active agent, protide surfactant, and their modified product, and blowing agent can be blowing agent reagent or the industrial goods of reset condition, also can be its solution or the composite blowing agent attaching foam stabiliser; Auxiliary material comprise one or more in curing agent, diluent, dispersant, reinforcing agent, fiber.
The preparation method of water-glass sand of the present invention is: mix with roughing sand, waterglass after blowing agent or its solution prefoam, mix with roughing sand after blowing agent and waterglass hybrid concurrency bubble, roughing sand, waterglass, blowing agent foam and one or more in the methods such as mixing together.
The using method of water-glass sand of the present invention is: the water-glass sand prepared adopts one or more of penetrating in the method such as sand back-up sand, perfusion back-up sand, gravity back-up sand, manual back-up sand to insert sandbox or core box, then by one or more methods sclerosis in the methods such as acid or potential acid curing agent sclerosis, physics dehydration sclerosis, the sclerosis of strong absorptive calcium salt class curing agent.
The present invention is retaining that the intrinsic clean environment firendly of water-glass sand, cost are low, while the more high advantage of intensity, significantly improve the problems such as the poor fluidity of water-glass sand, and the performances such as the good collapsibility of water-glass sand, special thermophysical property can be given, be the novel green mold material and the casting method that adapt to modern Foundry Production.
