摘　　要：在保证抗燃性能的前提下,对黏度等级为VG46的新型难燃液压液进行了研制。在参考进口难燃液压液性能的基础上,制定了VG46新型难燃液压液的技术指标。通过对基础油和添加剂的考察,新型难燃液压液的配方由特定结构的基础油,1.6%的复合抗氧剂(0.8%的烷基二苯胺+0.8%的单酚)及3.05%的复合抗磨极压剂(3.0%的含磷剂+0.05%的硫磷剂)组成。新型难燃液压液的闪点(开口)为288℃,通过了歧管着火试验(704℃),磨斑直径(75℃,1200 r/min,60 min,392 N)为0.42 mm,最大无卡咬负荷(常温,1500 r/min)为932 N,其抗燃性能,抗磨损性能和润滑性能均超过了进口难燃液压液,且较脂肪酸酯型难燃液压液的性价比提高了约15%。实际使用证明,新型难燃液压液可以替代进口难燃液压液使用。(图1表7参考文献3)For ensuring the fire-resistant performance,a novel non-flammable hydraulic fluid with viscosity grade of VG46 was developed.Based on the performance of imported non-flammable hydraulic fluid,the technical specifications of VG46 novel non-flammable hydraulic fluid were formulated.Based on the investigation of Stocks and additives,the formulation of the novel non-flammable hydraulic fluid was composed of special structure Stock,1.6%complex anti-oxidant(0.8%alkyl diphenylamine+0.8%monophenol)and 3.05%complex anti-wear extreme pressure additive(3.0%phosphorus agent+0.05%sulfur phosphorus agent).The flash point(opening)of the novel non-flammable hydraulic fluid was 288℃,and it had passed the manifold ignition test(704℃),the wear scare diameter(75℃,1200 r/min,60 min,392 N)was 0.42 mm,and the last non-seizure load(room temperature,1500 r/min)was 932 N.The fire-resistant performance,anti-wear performance and lubricity of the novel non-flammable hydraulic fluid were better than those of imported nonflammable hydraulic fluid,and its price performance ratio was about 15%higher than that of fatty acid ester nonflammable hydraulic fluid.The practice application showed that the novel non-flammable hydraulic fluid could replace the imported non-flammable hydraulic fluid.
