可生物降解的难燃液压液组合物及其制备方法
摘要：
本发明公开了一种可生物降解的难燃液压液组合物及其制备方法，该难燃液压液组合物包括重量比为100∶0.5～1.5∶0.05～2∶0.001～0.003的新戊基多元醇的不饱和脂肪酸酯、抗氧剂、极压抗磨剂和抗泡剂。与现有技术相比，由于本发明采用具有良好的润滑性、较好的粘度指数、较高的生物降解率、优良的高低温性能和良好的抗燃性的新戊基多元醇的不饱和脂肪酸酯为基础油，因此，本发明制备的难燃液压液组合物具有良好的可生物降解性、较高的粘度指数和良好的抗燃性，可应用于高温液压系统。
摘要（英）：

The invention discloses a biodegradable flame-resistant hydraulic fluid composition and a preparation method thereof, and the flame-resistant hydraulic fluid composition comprises unsaturated fatty acid ester of neopentyl polyol, an antioxidant, an extreme pressure antiwear agent, and an anti-foaming agent with a weight ratio of 100:0.5-1.5:0.05-2:0.001-0.003. Compared with the prior art, the invention adopts unsaturated fatty acid ester of neopentyl polyol as a basic oil which has good lubricity, a good viscosity index, a good biodegradation rate, excellent high and low temperature performance, and good flame resistance, so the flame-resistant hydraulic fluid composition prepared by the method of the invention has good biodegradability, a good viscosity index, and good flame resistance, and is applicable to a high temperature hydraulic system.
