摘　　要：为了制备出一种高含量外观接近透明的氧化聚乙烯蜡乳液,创造性的使用自制乳化剂,通过以氧化聚乙烯蜡固体蜡为主,采用常温高剪切的方式制备氧化聚乙烯蜡乳液,探讨了乳化剂用量、乳化时间和乳化温度对乳液性能的影响,结果表明采用乳化剂用量30%(相对OPE固体蜡),乳化温度130~135℃,剪切速度100~1500 r/min,乳化时间1 h能获得性能较佳的氧化聚乙烯蜡乳液,该配方工艺制备的乳液性能接近于高温高压制备的乳液。对优化后产品的性能进行了对比测试及对其在水性工业漆领域应用进行了简单探讨。In order to prepare an oxidized polyethylene wax lotion with high content and appearance close to transparency,self-made emulsifier was creatively used to prepare oxidized polyethylene wax lotion by using oxidized polyethylene wax solid wax as the main component and high shear at room temperature.The effects of emulsifier amount,emulsification time and emulsification temperature on the performance of lotion were discussed.The results showed that 30%of emulsifier amount(compared with OPE solid wax)was used,and the emulsification temperature was 130~135℃,The shear speed is 100~1500 r/min,and the emulsification time is 1 h.The oxidized polyethylene wax lotion with better performance can be obtained.The performance of the lotion prepared by this formula process is close to that of the lotion prepared under high temperature and high pressure.The performance of the optimized product was compared and tested,and its application in the field of water-based industrial paint was briefly discussed.
