摘要:用硼氢化钠,氯化亚锡乙醇溶液,氨水,在乳液体系中反应生成纳米有机锡,最佳的反应条件是:硼氢化钠与氯化亚锡的摩尔比为2.52:1,反应时间为2h,反应温度为45℃,反应得到的产物的最高产率为79.9%。利用红外光谱仪分析产物,并在环-块式摩擦磨损试验机和四球试验机上,测定了纳米有机锡添加到基础油后的摩擦磨损性能及纳米有机锡的添加量对这些性能的影响进行了考察,结果表明,含纳米有机锡1.5%(wt%)时,抗磨效果最佳。测定基础油、添加1.5%(wt%)纳米有机锡的基础油及添加T202的基础油三者的最大无卡咬负荷PB,结果表明添加T202后基础油的PB值最大。最后测定纳米有机锡与T202复配后的摩擦化学性能以及两者的添加量对基础油的摩擦磨损性能的影响,结果表明,当添加1.5%(wt%)纳米有机锡时和添加1%(wt%)T202复配时,润滑油的抗磨效果最佳。24622

Preparation of nanometer tin compound and chemical properties of the friction
Abstract: The nano-organic-tin is the reaction of sodium borohydride, ethanol solution of stannous chloride and ammonia water under the micro-nano-emulsion system. The best reaction condition is when the mole ratio of sodium borohydride and ethanol solution of stannous chloride is 2.52:1,the reaction time is 2h, the reaction temperature is 45℃ and the most prolific rate of the product is 79.9%.Using the infrared spectrometer product, and in the ring-pieces type friction and wear tester and four ball, determinate of nano-organic-tin added to base oil and the friction and wear properties after the addition of nano-organic-tin on these properties were investigated, results showed that when the content of nano-organic-tin is 1.5%(wt%),wear the best. Determine the largest non-card bite load PB of base oil, adding 1.5%(wt%) of nano-organic-tin in the base oil and adding the T202's base oil, the results show that the base oil after adding T202,its PB is maximum. Finally, determine the friction chemical about the compound of nano-organic-tin and T202 and the friction and wear performance impact of these two adding amount of base oil, the results show that when add 1.5%(wt%) of nano-organic-tin and add 1 %(wt%) of T202 compound, the anti-wear of lubricating oil gains its best effects.
