废油制作羟基酸型(芯)砂粘结剂的方法与应用

Method and Application of Manufacturing Hydroxy Acid from Used Oil for Mold and Core Sand Binder

介绍了一种用机械油、绝缘油、柴油机油、汽轮机油、汽缸油等各种废油制作羟基酸的方法及其作为型(芯)砂粘结剂的应用。该粘结剂制作简单,成本低,能够代替其它粘结剂如热芯盒树脂、植物油等用于铸件生产,并可实现废物利用。

Method and application of manufacturing hydroxyl acid from used oil for mold and core sand binder is introduced. These oil include motor oil, insulating oil, diesel oil, turbine oil, cylinder oil, etc. This kind of binder is easy-made and low cost, which can substitute other binder, such as heat core box resin and vegetable oil, etc, to be used in casting production and realize utilization of trash.
