Preparation of coated casting sand using unsaturated polyester resin as binder |
| abstract |
A crystalline unsaturated polyester, which is a scarcely tacky solid at room temperature but at a temperature somewhat above its softening temperature assumes a fluid state with a viscosity below about 500 poises, is used as a principal component of a binder for the preparation of a resin coated casting sand for use in shell mold casting of, particularly, aluminum alloys with an aim of facilitating the disintegration of molds and cores. The binder is mixed with a conventional foundry sand at an appropriately elevated temperature in the presence of an organic peroxide as a polymerization catalyst. The binder may preferably contain a cross-linking agent such as diallyl phthalate and optionally a silane as a coupling agent and/or a cross-linking accelerator. |
