Abstract
The invention discloses a novel phosphate adhesive sand as well as a preparation method and a using method thereof and aims to solve the problems of poor fluidity of the phosphate adhesive sand. The phosphate adhesive sand mainly comprises the following components: raw sand, a phosphate adhesive, a foaming agent, a curing agent and auxiliary materials; through cooperation with methods such as a pre-foaming method or a mixed foaming method, novel phosphate adhesive sand with excellent fluidity as well as sand molds and sand cores thereof can be prepared. The phosphate adhesive sand retains the inherent advantages of cleanness, environmental protection, high collapsibility and high strength of the phosphate adhesive sand; meanwhile, the problems such as poor fluidity of the phosphate adhesive sand can be greatly alleviated; the special properties such as thermo-physical property are given to the phosphate adhesive sand; the phosphate adhesive sand is a novel green casting material suitable for modern casting production, and the methods are casting methods suitable for modern casting production.
Description
Technical field
The invention belongs to casting field, a kind of phosphate binders sand and preparation and application thereof are provided.
Background technology
As an ancient and traditional industry, foundry industry is the most important basic activity of machinery manufacturing industry always.The difference of foundry industry production environment is well-known, and it all exists severe contamination to air, soil, water, along with the raising of people's environmental consciousness, realizes the common recognition that clean Foundry Production has become everybody.In modern foundry industry, the share of sand casting is more than 80%, is therefore the key realizing Green foundry to the research of sand casting.
Phosphate binders is as a kind of inorganic binder, the performance of the aspects such as its physics, chemistry, heat can meet Foundry Production requirement very well, and, recycle each link of whole process at phosphate binders preparation-phosphate binders sand and core preparation-casting-cleaning-old sand thereof substantially to produce and discharge without poisonous and harmful substance, belong to environmental protection casting and link agent.
Also there are some problems in existing phosphate binders Foundry Production, wherein, comparatively distinct issues are that phosphate binders viscosity is large, and phosphate binders sand poor fluidity, the modern Foundry Production of very difficult adaptation is in enormous quantities, high efficient production is complicated, accurate casting mold, core.
Summary of the invention
The present invention adds blowing agent in phosphate binders sand, and then the performance such as the mobility improving phosphate binders sand.
The present invention is directed to the problems such as the poor fluidity of phosphate binders sand existence, propose a kind of New Phosphorus hydrochlorate binding agent sand and preparation and application thereof.
The object of the invention is to be achieved through the following technical solutions:
Phosphate binders sand of the present invention by roughing sand, phosphate binders, blowing agent, curing agent, auxiliary material through mixing, mass fraction ratio=100:(1 ~ 40 of roughing sand, phosphate binders, blowing agent, curing agent, auxiliary material): (0.005 ~ 20): (0.1 ~ 15): (0 ~ 10).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; Phosphate binders comprises one or more in phosphoric acid, mono phosphoric acid ester salt, salt of phosphoric acid; 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; Curing agent comprises one or more in metal oxide, hydroxide, complex compound; Auxiliary material comprise one or more in diluent, dispersant, reinforcing agent, fiber.
The preparation method of phosphate binders sand of the present invention is: mix with roughing sand, phosphate binders, curing agent after blowing agent or its solution prefoam, mixes with roughing sand, curing agent after blowing agent, phosphate binders hybrid concurrency bubble, roughing sand, phosphate binders, blowing agent, curing agent foam and one or more in the methods such as mixing together.
The using method of phosphate binders sand of the present invention is: the phosphate binders 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, one or more method sclerosis from hard, air hardening in hard by heat, obtains sand mold or core.
The present invention is retaining that the intrinsic clean environment firendly of phosphate binders sand, collapsibility are good, while the more high advantage of intensity, significantly improve the problems such as the poor fluidity of phosphate binders sand, and the performances such as the special thermophysical property of phosphate binders sand can be given, be the novel green mold material and the casting method that adapt to modern Foundry Production.
