The present invention relates to a kind of bonding agent, and in particular to a kind of casting chaplet box sand mold or the hot sticky glue of core, wherein, hot sticky collagen material includes refractory aggregate, bonding agent, suspending agent, curing agent, coupling agent and water.The refractory aggregate, bonding agent, suspending agent, curing agent, coupling agent and water weight portion are respectively:100 parts, 5~10 parts, 2~5 parts, 0.1~0.2 part, 0.1~0.2 part, 60~100 parts.The bonding agent of the present invention is carrier using water, and transport is used and casting process both environmental protection, and safety.

Description

A kind of casting chaplet box sand mold or the hot sticky glue of core
Technical field
The present invention relates to a kind of bonding agent, and in particular to a kind of casting chaplet box sand mold or the hot sticky glue of core.
Background technology
Sand mold or core that core shooter is manufactured, mold clearing temperature at 50~200 DEG C, for improve production efficiency. Repaired after production scene is intended to depanning immediately, then bonding, mould assembling is carried out at once using the waste heat of sand mold or core Etc. operation.General 1~2 minute bonding time just, is so accomplished by the hot lower bonding agent that can be used immediately.
Existing bonding agent typically with oils bonding agent as carrier, if using machine oil class as carrier, using depositing Very dangerous during putting, substantial amounts of flue gas can be produced in casting process, very not environmentally.
Content of the invention
For the defect that above-mentioned prior art is present, it is an object of the invention to provide one kind uses process safety, cast Process and the casting chaplet box sand mold of environmental protection or the hot sticky glue of core.
For reaching above-mentioned purpose, the technical scheme is that:A kind of casting chaplet box sand mold or the hot sticky glue of core, its In, hot sticky collagen material includes refractory aggregate, bonding agent, suspending agent, curing agent, coupling agent and water.The refractory aggregate, bonding Agent, suspending agent, curing agent, coupling agent and water weight portion are respectively:100 parts, 5~10 parts, 2~5 parts, 0.1~0.2 part, 0.1~ 0.2 part, 60~100 parts.
During using above-mentioned technical proposal, hot sticky glue is adopted and uses water as carrier, very safe during using and depositing, and is being poured Steam can be produced only during note, without producing flue gas, compared with the oil carrier referred in background technology, it is clear that more ring Protect.
Further, the refractory aggregate is one or more in silica flour, mullite powder, forsterite powder and talcum powder The mixture of arbitrary proportion, granularity are 300~800 mesh.The refractory aggregate of above-mentioned several types is conventional several types.
Further, the bonding agent is epoxy resin, phenolic resin, furane resins, rosin, silester, polyvinyl alcohol Mixture with one or more arbitrary proportions in polyvinyl butyral resin.The bonding agent of above-mentioned several types is conventional several Type.
Further, the suspending agent be sodium bentonite, lithium bentonite, rectorite and organobentonite in one kind or The mixture of several arbitrary proportions.The suspending agent of above-mentioned several types is conventional several types.
Further, the one kind of the coupling agent for silane.Silane is conventional coupling agent.
Further, the curing agent is the one kind in polyamide, p-methyl benzenesulfonic acid and methenamine.Above-mentioned a few species The curing agent of type is conventional curing agent.
Specific embodiment
The use temperature conditionss of a kind of casting chaplet box sand mold of the present invention or core with hot sticky glue:Sand mold or the temperature of core For 80~200 DEG C.
