Abstract
The invention relates to a binding agent, in particular to hot viscose for casting hot core box sand molds or sand cores. The hot viscose comprises, by weight, 100 parts of refractory aggregate, 5-10 parts of a binding agent, 2-5 parts of a suspending agent, 0.1-0.2 part of a curing agent, 0.1-0.2 part of a coupling agent and 60-100 parts of water. Water is used as a carrier for the binding agent, and the hot viscose is environmentally friendly and safe in the transporting, using and casting processes.
Description
Technical field
The present invention relates to a kind of bonding agent, be specifically related to a kind of casting chaplet box sand mold or the hot sticky glue of core.
Background technology
The produced sand mold of core shooter or core, mold clearing temperature at 50 ~ 200 DEG C not etc., in order to enhance productivity.Repair immediately after depanning is all wished in production scene, then utilize the waste heat of sand mold or core to carry out the operations such as bonding, mould assembling at once.General bonding time 1 ~ 2 minute just, so just needed at the hot lower bonding agent that can use immediately.
Existing bonding agent generally with oils bonding agent for carrier, if adopt machine oil class as carrier, then deposit in process very dangerous in use, a large amount of flue gases can be produced in casting process, very not environmentally.
Summary of the invention
For the defect that above-mentioned prior art exists, the object of the present invention is to provide a kind of use procedure safety, casting process is the casting chaplet box sand mold of environmental protection or the hot sticky glue of core again.
For achieving the above object, technical scheme of the present invention is: a kind of casting chaplet box sand mold or the hot sticky glue of core, and wherein, hot sticky collagen material comprises refractory aggregate, bonding agent, suspending agent, curing agent, coupling agent and water.Described 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.
When adopting technique scheme, hot sticky glue adopts water as carrier, is using and is depositing in process very safe, only can produce steam, and can not produce flue gas in casting process, compared with the oil carrier mentioned in background technology, and obviously environmental protection more.
Further, described refractory aggregate is the mixture of one or more arbitrary proportions in silica flour, mullite powder, forsterite powder and talcum powder, and granularity is 300 ~ 800 orders.The refractory aggregate of above-mentioned several types is conventional several types.
Further, described bonding agent is the mixture of one or more arbitrary proportions in epoxy resin, phenolic resins, furane resins, rosin, silester, polyvinyl alcohol and polyvinyl butyral resin.The bonding agent of above-mentioned several types is conventional several types.
Further, described suspending agent is the mixture of one or more arbitrary proportions in sodium bentonite, lithium bentonite, rectorite and organobentonite.The suspending agent of above-mentioned several types is conventional several types.
Further, described coupling agent is the one of silane.Silane is conventional coupling agent.
Further, described curing agent is the one in polyamide, p-methyl benzenesulfonic acid and methenamine.The curing agent of above-mentioned several types is conventional curing agent.
