一种铝合金压铸蜡乳液脱模剂的研制

摘要

研究了用氧化聚乙烯蜡、58#全炼蜡制备铝合金压铸蜡乳液脱模剂的方法。考查了乳化剂类型、乳化剂用量、乳化工艺对乳液稳定性的影响。实验结果表明，当复合乳化剂用量为复合蜡的30%，乳化温度为95℃，搅拌速度为500~700 r/min时，乳化时间为40~45 min，可以制取一种稳定的用于铝合金压铸蜡乳液脱模剂。%A preparation method of wax-emulsion releasing agent for aluminium alloy die casting from oxidized polyethylene wax and 58# fully refined paraffin wax was studied. Effects of emulsifier type, emulsifier dosage and emulsifying process on the emulsion stability were studied. The results show that, when the compounded emulsifier dosage is 30%of the mixed wax mass, the emulsifying-temperature is 95℃, the stirring speed is between 500~700 r/min, the emulsifying time is between 40~45min, stable wax-emulsion releasing agent for aluminium alloy die casting can be prepared.
