| titleOfInvention | A kind of Foundry Coated Sand of forming low bulk and preparation method thereof |
| abstract | The invention discloses a kind of Foundry Coated Sand of forming low bulk and preparation method thereof, comprise the following steps:1) quartz sand, spodumene, graphite are crushed, crosses 200 mesh sieves and form mixed sand；2）Mixed sand after heating is added to the thermoplastic phenolic resin of chlorinated paraffin and 0.5 times of amount while mixed grind；3）Methenamine is dissolved in water and forms solution；4）Close puddle mixer heating tube, it is air-cooled to 60 DEG C when crush, be screened in cooler, air-cooled to less than 25 DEG C, shake out pack it is standby.Synergist is made by special process in the present invention, curing rate is fast while improving the thermal diffusivity of precoated sand, mobility, intensity, gets angry small, prevents metal casting surface porosity, addition graphite, dimethyl silicone polymer have good lubricity, low bulk, friction is reduced, improve release property, iron oxide, prevent cast(ing) surface from producing elephant skin, manufactured precoated sand good combination property, be effectively improved casting inside and outside surface quality. |
