• Phosphorous amine lubricant additives

  Lubricant additives are produced by reacting an alkoxylated amine with phosphorous acid. The additives preferably also contain a boron moiety which is reacted with the phosphorous acid and amine, preferably in a one step reaction. More preferably, a mono-functional alcohol or a long-chain aliphatic carboxylic acid is added to this mixture. The additives are particularly useful in metalworking oils and particularly as extreme pressure additives to replace the currently used chlorinated paraffin additives.

  润滑油添加剂是通过烷氧基化胺与磷酸反应制得的。添加剂最好还含有一个硼基，该硼基与磷酸和胺反应，最好是一步反应。更优选的是，在该混合物中加入单官能醇或长链脂肪族羧酸。这种添加剂在金属加工油中特别有用，尤其是作为极压添加剂，可以取代目前使用的氯化石蜡添加剂。

The non-crosslinked foamed polyethylene resin particles can simply afford an antistatic molded non-crosslinked foamed polyethylene resin body that has a small shrinkage ratio with respect to mold dimension, is deformed in a small degree, and has good surface stretch. Shrinkage ratio = (BD-VBD) x 100/VBD (1) In the formula, BD is a bulk density of the non-crosslinked foamed polyethylene resin particles at 23°C and 0.1 MPa (under standard atmospheric pressure), and VBD is a bulk density of the non-crosslinked foamed polyethylene resin particles at 23°C under a reduced pressure of 0.002 MPa or less.
