摘要
为选择合适的基础油并制出相应的稠化剂,调配出合适锥入度的集中润滑系统的基础润滑脂.研究选择硫化异丁烯(T321)和MoDDP作为极压抗磨剂,以提高极压抗磨性.选择各单剂及其复配剂,采用正交试验设计,筛选最优方案.结果表明,试验筛选的最优方案为:T321的添加量为3.0%,MoDDP的添加量为2.0%时,锂基脂的最大无卡咬负荷(PB)值为981N,说明在不考虑其他添加剂影响的前提下,所制备的锂基润滑脂极压抗磨性能方面符合使用标准,且优于市面上的润滑脂.
This experiment was carried out to choose appropriate base oil and made the corresponding thickener, then to mix the centralism lubrication foundation lubricant oil with the appropriate penetration. The curing isobutene （T321） and MoDDP were taken as the anti-wear additives for extreme-pressure. Sin- gle additive and complex formulation of two additives were designed by orthogonal test to chose the opti- mum additive scheme. The extreme-pressure and abrasion resistance properties were evaluated by maximum nonseizure load P~ which was got through the four-ball method in various plans to reflect. The results dem- onstrated that the optimum additive percentage of T321 was 3. 0~ ,while that of MoDDP was 2. 0%, under this condition,the PB of lithium based grease reached to 981 N. This indicated that the anti-wear property of prepared lithium based grease reached to the standard and was better than those in the markets.
