汽车防锈蜡的研制

摘要

采用自制氧化蜡制备汽车防锈乳化蜡,考察了氧化蜡的质量分数、复合乳化剂的质量分数、乳化温度、搅拌速率、乳化时间及防锈剂类型和用量对乳液性能的影响.结果表明,在氧化蜡的质量分数为15%,复合乳化剂的质量分数为7%,乳化温度为85～90℃,搅拌速率在1 000 r/min左右,乳化时间为40 min时,可以得到稳定的乳化蜡.选择防锈剂T-704添加到乳化蜡溶液中去,制备出性能稳定,防锈效果好的乳化型汽车防锈蜡.%Method of preparing anti-rusting wax-emulsion with oxidized wax was studied.Factors of affecting emulsion stability, such as the quantity of oxidized wax and complex emulsifier, emulsifying temperature , stirring speed, emulsifying time, and anti-rusting type and agent, were investigated.Experiment results showed that one stable wax-emulsion can be prepared when quantity of oxidized wax is 15％ , quantity of complex emulsifier is 7％ ,emulsifying temperature is 85 ～90 ℃ ，stirring speed is 1000 r/min,and emulsifying time is 40 min.One good anti-rusting wax-emulsion for automobile can be prepared when the antirust T-704 was selected.
