摘要
在筛选原材料的基础上,通过优化组分之间的配比,得出的配方(质量分数)为:某牌号机械油为25%、脂类化合物为12.5%、羊毛脂为3.3%、Span80为1.6%、OP-10为3.2%、黄原胶为0.2%、防腐剂为0.3%、防氧化剂为0.2%、消泡剂为0.3%、水为53.4%;通过转相乳化法制得的脱模剂具有良好稳定性、高温润湿性和成膜性。在实际应用中发现,脱模剂以1∶90的比例稀释,具有较好的脱模效果。
Aqueous releasing agent is extensively used in the die casting because of its series of advantages. Based on the selection of raw materials, through optimizing the composition proportion, the optimized proportion of aqueous releasing agent is composed of 25%machie oil, 12.5% lipid, 3.3% lanolin, 1.6% span 80, 3.2% OP-10, 0.2% xanthan gum, 0.3% antiseptic, 0.3% antioxidant, 0.3% defoamer and 53.4% water. The releasing agent prepared by phase conversion emulsion method exhibits a better stability,and high temperature wettability and film properties. The practical application shows that the releasing agent exhibits a preferable releasing ability with being diluted as 1∶90 ratio, which is equivalent to an abroad releasing agent in comprehensive properties, however, showing the better glossiness. Meanwhile, the releasing agent has the lower cost than that of two kinds of abroad ones, decreased by 40%~50%.
