Knowledge Description

Epc coating formula

涂料成分为镁砂粉30-50%、珠光粉20-40%、云母粉15-30%、硅溶胶3-9%、白乳胶1-5%、聚丙烯酰胺0.1-0.8%、羧甲基纤维素钠0.1-0.8%、吸附剂1-6%、阻燃剂0.3-2%

制备时先将吸附剂、羧甲基纤维素钠、聚丙烯酰胺分别加水配成溶液,再与骨料及其他成分混合搅拌而成。本发明的涂料能有效吸附泡沫塑料模样热解产生的液态产物,大大减少铸件的孔隙率,并在铸型-镁液界面间形成还原性保护气氛层,使镁合金表面形成保护膜,阻止氧化进行,防止了浇注时镁合金在铸型内的燃烧,有利于获得表面光洁、无氧化皱皮的镁合金铸件
