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。

Abstract

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%

0%.
