摘　　要：以石蜡和聚乙烯蜡为原料制备改性石蜡,并进一步制备乳化蜡,考察了乳化剂及工艺条件对乳化蜡性能的影响。结果表明,在HLB值为10的复合乳化剂Tween 20+Span 40+硬脂酸的用量为24%,乳化温度为90℃,搅拌速度为900 r·min-1,乳化时间为40 min的工艺条件下,制得稳定性和分散性较好的乳化蜡,适合作造纸施胶用蜡。Paraffin wax and polyethylene wax were used as raw materials for the preparation of modified paraffin that was further processed to prepare wax emulsion for paper - making. Effects of emulsifier and process conditions on performance of the wax emulsion were investigated. Results showed that under condition as the HLB of compounded emulsifier consisting of Tween 20 ＋ Span 40 ＋ Stearie acid is 10; the dosage of compounded emulsifier is 24% ;the temperature is 90 ℃ ;the stirring speed is 900 r · min ＇;the emulsifying time is 40 in;the prepared wax emulsion shows good stability and dispersity. It is suitable for use in paper sizing process.
